1 Introduction

NOTE

l In this solution, the OptiX RTN 910 is connected to an RNC and BSC directly or through a regional backhaul network. l The OptiX RTN 910 provides a wide range of interfaces and service bearer technologies to adapt to the regional backhaul network. The regional backhaul network can be a time-division multiplexing (TDM) network or packet switching network (PSN). l The OptiX RTN 910 supports the Ethernet over SDH (EoSDH) function and Ethernet over PDH (EoPDH) function. Therefore, packet services can be backhauled through a TDM network. l The OptiX RTN 910 supports the pseudo wire emulation edge-to-edge (PWE3) technology. Therefore, TDM, ATM, and Ethernet services can be backhauled through a PSN. l The OptiX RTN 910 supports the VLAN sub-interface function. Therefore, MPLS packet services can be backhauled through a Layer 2 network. l When three or more microwave directions are required, cascade several sets of the OptiX RTN 910 or use the OptiX RTN 950 or OptiX RTN 980 that provides more powerful functions and supports more microwave directions.

1.2 Components The OptiX RTN 910 adopts a split structure. The system consists of the IDU 910 and the ODU. Each ODU is connected to the IDU through an IF cable.

IDU 910 The IDU 910 is the indoor unit for an OptiX RTN 910 system. It receives and multiplexes services, performs service processing and IF processing, and provides the system control and communications function. Table 1-1 lists the basic features of the IDU 910.

There are two methods for mounting the ODU and the antenna: direct mounting and separate mounting. l

The direct mounting method is generally adopted when a small- or medium-diameter and single-polarized antenna is used. In this situation, if one ODU is configured for one antenna, the ODU is directly mounted at the back of the antenna. If two ODUs are configured for one antenna, an RF signal combiner/splitter (hence referred to as a hybrid coupler) must be mounted to connect the ODUs to the antenna. Figure 1-3 illustrates the direct mounting method. The direct mounting method can also be adopted when a small- or medium-diameter and dual-polarized antenna is used. Two ODUs are mounted onto an antenna using an orthomode transducer (OMT). The method for installing an OMT is similar to that for installing a hybrid coupler.

The separate mounting method is adopted when a large- or medium-diameter and singleor dual-polarized antenna is used. Figure 1-4 shows the separate mounting method. In this situation, a hybrid coupler can be mounted (two ODUs share one feed boom). Figure 1-4 Separate mounting

NOTE

The OptiX RTN 910 provides an antenna solution that covers the entire frequency band, and supports single-polarized antennas and dual-polarized antennas with diameters of 0.3 m to 3.7 m along with the corresponding feeder system.

Lower order cross-connect module LOXC

The source TDM service unit transmits VC-4 signals to the higher order cross-connect module over VC-4 buses. If the VC-4 signals carry only VC-4 services, the higher order cross-connect module processes the VC-4 signals and then transmits the signals to the sink TDM service unit. If the VC-4 signals include VC-12 or VC-3 services, the higher order cross-connect module grooms the VC-12 or VC-3 services to the lower order cross-connect module. The lower order cross-connect module processes the VC-12 or VC-3 services and then transmits the services back to the higher order cross-connect module. The higher order cross-connect module processes the services and then transmits the services to the sink TDM service unit.

Clock Unit The clock unit selects an appropriate clock source from external clock sources or service clock sources at service ports based on clock priorities. Locking the clock source by means of the phase-locked loop, the clock unit provides the system clock and frame headers for service signals and overhead signals to other units on the system control, switching, and timing board and the other boards.

Auxiliary Interface Unit The auxiliary interface unit processes inputs and outputs of the orderwire phone port, asynchronous data port, synchronous data port, and external alarm port. The port for monitoring an outdoor cabinet and the clock/time port share one port.

Power Supply Unit The power supply unit performs the following functions: l

Combines and then converts the two -48 V power inputs into the power supply required by the chips of the other units on the local board.

l

Combines and then converts the two -48 V power inputs into the +3.3 V power supply required by the other boards in the IDU.

l

Combines and then converts the two -48 V power inputs into the +12 V power supply required by the fan.

NOTE

l The external clock port, outdoor cabinet monitoring port, and wayside E1 port share one port physically. This port can also transparently transmit DCC bytes, orderwire overhead bytes, and synchronous/ asynchronous data overhead bytes. This port, however, can implement only one of the preceding functions at one time. l The 64 kbit/s synchronous data port can transparently transmit one orderwire byte. This port, however, can transmit 64 kbit/s synchronous data or transparently transmit one orderwire byte at one time. l Time ports TOD are reserved for running the high-precision time protocol (IEEE 1588 protocol) and are not used in this product version.

Auxiliary ports and management ports use RJ45 connectors. The pin assignments for the ports, however, are different. Figure 3-7 shows the front view of the RJ45 connector.

3.3.5 DIP Switches and CF Card This board has a set of DIP switches and a pluggable CF (compact flash) card. NE databases, system parameters (including NE-IP, NE-ID, and subnet mask), software packages, and NE logs are stored on the CF card. After you press the CRV button on the system control, switching, and timing board and hold it for eight seconds, the data stored on the CF card will be loaded to the board. To synchronize the NE databases, system parameters, and NE logs on the system control, switching, and timing board to the CF card, enable the regular backup function.

l

The CPU unit controls and manages the other boards in the IDU and collects alarms and performance events using the control bus.

l

The CPU unit controls and manages the ODU by transmitting the ODU control signal to the SMODEM unit in the IF board over the control bus in the backplane.

l

The CPU unit enables the packet switching unit using the control bus to groom Ethernet service packets.

l

The CPU unit processes Ethernet protocol packets from the packet switching unit using the control bus.

l

The CPU unit processes network management messages in DCCs using the logic control unit.

l

The CPU unit communicates with the NMS by its Ethernet NM port and NE cascading port.

l

The CPU unit implements software loading by reading information from the CF card with the bus.

l

The CPU unit monitors and manages an outdoor cabinet by reading the outdoor cabinet monitoring signal with the bus.

l

The logic control unit decodes the address read/write signals from the CPU unit and enables FPGA loading.

l

The logic control unit cross-connects the overheads between the auxiliary interface unit, the CPU unit, and other boards. This helps to achieve the following purposes: – Adding or dropping DCC information processed by the CPU unit – Adding or dropping orderwire and asynchronous data services – Exchanging the orderwire bytes, DCC bytes, and K bytes between different lines

Packet Switching Unit The packet switching unit grooms services and processes protocols for Ethernet services (including Native Ethernet services and MPLS/PWE3 packets carried over Ethernet). l

After receiving Ethernet services from the Ethernet interface unit on the board or an Ethernet board, the packet switching unit grooms the Ethernet services based on the configurations that are delivered by the system control and communication unit.

l

After receiving protocol packets from the Ethernet interface unit on the board or an Ethernet board, the packet switching unit transmits the protocol packets to the system control and communication unit for processing. After processing, the system control and communication unit sends the protocol packets back to the packet switching unit. The packet switching unit transmits the protocol packets to the Ethernet interface unit or the Ethernet board.

Cross-Connect Unit The cross-connect unit grooms services over the entire system using the higher order crossconnect module and the lower order cross-connect module. Figure 3-15 shows the functional block diagram of the cross-connect unit.

Higher order cross-connect module HOXC

SinkTDM service unit

Lower order cross-connect module LOXC

The source TDM service unit transmits VC-4 signals to the higher order cross-connect module over VC-4 buses. If the VC-4 signals carry only VC-4 services, the higher order cross-connect module processes the VC-4 signals and then transmits the signals to the sink TDM service unit. If the VC-4 signals include VC-12 or VC-3 services, the higher order cross-connect module grooms the VC-12 or VC-3 services to the lower order cross-connect module. The lower order cross-connect module processes the VC-12 or VC-3 services and then transmits the services back to the higher order cross-connect module. The higher order cross-connect module processes the services and then transmits the services to the sink TDM service unit.

Ethernet Signal Access Unit The Ethernet signal access unit transmits/receives FE/GE signals and works with the Layer 2 switching module to implement the Layer 2 switching function. l

In the receive direction, after restructuring, decoding, and performing serial/parallel conversion for electrical signals, the Ethernet signal access unit performs frame delimitation and preamble processing, extracts Ethernet frames, and performs cyclic redundancy check (CRC) and Ethernet performance measurement. If optical signals are received, the Ethernet signal access unit performs O/E conversion before performing the preceding operations.

l

In the transmit direction, after performing frame delimitation, preamble addition, CRC code computation, and Ethernet performance measurement, the Ethernet signal access unit performs serial/parallel conversion for signals, encodes the signals, and transmits the signals to the Ethernet port. In the case of an optical port, after performing the preceding operations, the Ethernet signal access unit needs to perform E/O conversion before transmitting signals through the optical port.

E1 Signal Processing Unit The E1 signal processing unit allows access of, codes/decodes, and maps/demaps E1 electrical signals and processes clock overheads. Signal processing on this unit is the same as that on the SP3S/SP3D. For details, see 3.16.3 Working Principle and Signal Flow.

Signal processing on the STM-1 signal processing unit is the same as that on the SL1D. For details, see 3.14.3 Working Principle and Signal Flow.

Clock Unit The clock unit selects an appropriate clock source from external clock sources or service clock sources at service ports based on clock priorities. Locking the clock source by means of the phase-locked loop, the clock unit provides the system clock and frame headers for service signals and overhead signals to other units on the system control, switching, and timing board and the other boards.

Auxiliary Interface Unit The auxiliary interface unit processes inputs and outputs of the orderwire phone port, asynchronous data port, synchronous data port, and external alarm port. The port for monitoring an outdoor cabinet and the clock/time port share one port.

NOTE

The NMS/COM port and the EXT port are equivalent to two ports on a hub. This means that no external Ethernet link should be configured between the two ports during the networking process; otherwise, an Ethernet loop will be formed. As a result, a broadcast storm is generated on the network, leading to repeated resetting of NEs.

When the GE SFP ports and STM-1 SFP ports on the CSHC function as optical ports, optical modules are required. l

When dual-fiber bidirectional SFP optical modules are used to provide GE ports, one SFP optical module, like an STM-1 SFP optical module, provides one TX port and one RX port. For details, see Figure 3-21, in which TX represents the transmit port and RX represents the receive port. One optical fiber is connected to each port.

l

When single-fiber bidirectional optical modules are used to provide GE ports, one optical module provides only the port on the left. This port is an optical port that can receive and transmit service signals. One optical fiber is connected to this port.

3.4.5 DIP Switches and CF Card This board has a set of DIP switches and a pluggable CF (compact flash) card. NE databases, system parameters (including NE-IP, NE-ID, and subnet mask), software packages, and NE logs are stored on the CF card. After you press the CRV button on the system control, switching, and timing board and hold it for eight seconds, the data stored on the CF card will be loaded to the board. To synchronize the NE databases, system parameters, and NE logs on the system control, switching, and timing board to the CF card, enable the regular backup function.

NOTE

The software packages on the CF card are synchronized with those on the system control, switching, and timing board during package diffusion. Therefore, automatic backup mechanisms or manual operations are not needed to synchronize software packages on the system control, switching, and timing board and the CF card. If the system control, switching, and timing board and the CF card have different software packages or data, the SWDL_PKGVER_MM alarm will be reported.

The logic control unit cross-connects the overheads between the auxiliary interface unit, the CPU unit, and other boards. This helps to achieve the following purposes: – Adding or dropping DCC information processed by the CPU unit – Adding or dropping orderwire and asynchronous data services – Exchanging the orderwire bytes, DCC bytes, and K bytes between different lines

Packet Switching Unit The packet switching unit grooms services and processes protocols for Ethernet services (including Native Ethernet services and MPLS/PWE3 packets carried over Ethernet). l

After receiving Ethernet services from the Ethernet interface unit on the board or an Ethernet board, the packet switching unit grooms the Ethernet services based on the configurations that are delivered by the system control and communication unit.

l

After receiving protocol packets from the Ethernet interface unit on the board or an Ethernet board, the packet switching unit transmits the protocol packets to the system control and communication unit for processing. After processing, the system control and communication unit sends the protocol packets back to the packet switching unit. The packet switching unit transmits the protocol packets to the Ethernet interface unit or the Ethernet board.

Cross-Connect Unit The cross-connect unit grooms services over the entire system using the higher order crossconnect module and the lower order cross-connect module. Figure 3-29 shows the functional block diagram of the cross-connect unit. Figure 3-29 Functional block diagram of the cross-connect unit Source TDM service unit

The source TDM service unit transmits VC-4 signals to the higher order cross-connect module over VC-4 buses. If the VC-4 signals carry only VC-4 services, the higher order cross-connect module processes the VC-4 signals and then transmits the signals to the sink TDM service unit. If the VC-4 signals include VC-12 or VC-3 services, the higher order cross-connect module grooms the VC-12 or VC-3 services to the lower order cross-connect module. The lower order cross-connect module processes the VC-12 or VC-3 services and then transmits the services back to the higher order cross-connect module. The higher order cross-connect module processes the services and then transmits the services to the sink TDM service unit.

Ethernet Signal Access Unit The Ethernet access unit receives/transmits FE/GE signals, and works with the Layer 2 switching unit to provide Layer 2 switching functions. In addition, the Ethernet signal access unit receives IEEE 1588v2 messages (not supported by SFP electrical modules), adds timestamps to the messages, and sends the messages to the clock unit. l

In the receive direction, after restructuring, decoding, and performing serial/parallel conversion for electrical signals, the Ethernet signal access unit performs frame delimitation and preamble processing, extracts Ethernet frames, and performs cyclic redundancy check (CRC) and Ethernet performance measurement. If optical signals are received, the Ethernet signal access unit performs O/E conversion before performing the preceding operations.

l

In the transmit direction, after performing frame delimitation, preamble addition, CRC code computation, and Ethernet performance measurement, the Ethernet signal access unit performs serial/parallel conversion for signals, encodes the signals, and transmits the signals to the Ethernet port. In the case of an optical port, after performing the preceding operations, the Ethernet signal access unit needs to perform E/O conversion before transmitting signals through the optical port.

E1 Signal Processing Unit The E1 signal processing unit transmits/receives and processes E1 electrical signals, and works with the packet switching unit and cross-connect unit to transport various signals. l

In the receive direction, the E1 signal processing unit performs the following functions: – Implements the functions of impedance matching, signal equalization, level conversion, clock recovery, de-jitter, and decoding for received E1 signals. – If the received E1 signals need to be transmitted through the TDM plane in form of native E1 signals, the E1 signal processing unit maps the E1 signals into VC-4s, performs pointer processing, and sends the signals to the cross-connect unit for grooming. – If the received E1 signals need to be transmitted through the packet switched plane in form of packet services, the E1 signal processing unit performs PWE3 encapsulation for a required service category such as ATM service, IMA service, and CES service, and sends the encapsulated packets to the packet switching unit for grooming.

l

In the transmit direction, the E1 signal processing unit performs the following functions: – For the VC-4 signals from the cross-connect unit, the E1 signal processing unit implements the functions of clock processing, demapping, and overhead processing, and extracts E1 signals.

– For the PWE3 packets from the packet switching unit, the E1 signal processing unit implements the functions of protocol processing, PWE3 decapsulation, queue scheduling, and other QoS processing, and sends out E1 signals. – For output E1 signals, the interface part of the E1 signal processing unit implements the functions of encoding, de-jitter, pulse shaping, and line driving, and sends the signals to an E1 port.

Clock Unit The clock unit selects an appropriate clock source from external clock sources or service clock sources at service ports based on clock priorities. Locking the clock source by means of the phase-locked loop, the clock unit provides the system clock and frame headers for service signals and overhead signals to other units on the system control, switching, and timing board and the other boards. The clock unit receives IEEE 1588v2 messages from the FE signal access unit and GE signal access unit on the local board or from other Ethernet service boards, and performs protocol processing to implement clock/time synchronization.

Auxiliary Interface Unit The auxiliary interface unit processes inputs and outputs of the orderwire phone port, asynchronous data port, synchronous data port, port for monitoring an outdoor cabinet, and external alarm port. The port for monitoring an outdoor cabinet and the clock/time port share one port.

Power Supply Unit The power supply unit performs the following functions: l

Combines and then converts the two -48 V power inputs into the power supply required by the chips of the other units on the local board.

l

Combines and then converts the two -48 V power inputs into the +3.3 V power supply required by the other boards in the IDU.

l

Combines and then converts the two -48 V power inputs into the +12 V power supply required by the fan.

NE databases, system parameters (including NE-IP, NE-ID, and subnet mask), software packages, and NE logs are stored on the CF card. After you press the CRV button on the system control, switching, and timing board and hold it for eight seconds, the data stored on the CF card will be loaded to the board. To synchronize the NE databases, system parameters, and NE logs on the system control, switching, and timing board to the CF card, enable the regular backup function. NOTE

The software packages on the CF card are synchronized with those on the system control, switching, and timing board during package diffusion. Therefore, automatic backup mechanisms or manual operations are not needed to synchronize software packages on the system control, switching, and timing board and the CF card. If the system control, switching, and timing board and the CF card have different software packages or data, the SWDL_PKGVER_MM alarm will be reported.

a: The ODU-PWR switch is equipped with a lockup device. To turn on or turn off the switch, you need to first pull the switch lever slightly outwards. When the switch is set to "O", it indicates that the circuit is open. When the switch is set to "I", it indicates that the circuit is closed. b: A 5D IF cable is connected to an IF board; therefore, an IF jumper is not required.

Labels There is a high temperature warning label, an operation warning label, and an operation guidance label on the front panel. The high temperature warning label indicates that the board surface temperature may exceed 70°C when the ambient temperature is higher than 55°C. If surface temperature reaches this level, you need to wear protective gloves before handling the board. The operation warning label indicates that the ODU-PWR switch must be turned off before the IF cable is removed. The operation guidance label indicates that the switch must be pulled slightly outwards before the switch is set to the "I" or "O" position.

NOTE

a: The ODU-PWR switch is equipped with a lockup device. To turn on or turn off the switch, you need to first pull the switch lever slightly outwards. When the switch is set to "O", it indicates that the circuit is open. When the switch is set to "I", it indicates that the circuit is closed. b: A 5D IF cable is connected to an IF board; therefore, an IF jumper is not required.

Labels There is a high temperature warning label, an operation warning label, and an operation guidance label on the front panel. The high temperature warning label indicates that the board surface temperature may exceed 70°C when the ambient temperature is higher than 55°C. If surface temperature reaches this level, you need to wear protective gloves before handling the board. The operation warning label indicates that the ODU-PWR switch must be turned off before the IF cable is removed. The operation guidance label indicates that the switch must be pulled slightly outwards before the switch is set to the "I" or "O" position.

Combiner interface unit

Combines the ODU control signals, microwave service signals, and -48 V power supplies and transmits the combined signals to the IF cable.

Control Signal Processing The board is directly controlled by the CPU unit on the system control and communication unit. The CPU unit issues configuration and query commands to the other units of the board over the control bus. These units then report command responses, alarms, and performance events to the CPU unit over the control bus. The logic control unit decodes the address read/write signals from the CPU unit of the system control and communication unit.

Power Supply Unit The power supply unit performs the following functions: l

Performs soft-start and filtering operations for the -48 V power received from the power supply bus in the backplane and supplies -48 V power to the ODU after performing DCDC conversion.

l

Performs soft-start and filtering operations for the -48 V power received from the power supply bus in the backplane and supplies +3.3 V power to the other units on the ISU2 after performing DC-DC conversion.

Clock Unit This unit receives the system clock from the control bus in the backplane and provides clock signals to the other units on the board.

a: The ODU-PWR switch is equipped with a lockup device. To turn on or turn off the switch, you need to first pull the switch lever slightly outwards. When the switch is set to "O", it indicates that the circuit is open. When the switch is set to "I", it indicates that the circuit is closed. b: A 5D IF cable is connected to an IF board; therefore, an IF jumper is not required.

Labels There is a high temperature warning label, an operation warning label, and an operation guidance label on the front panel. The high temperature warning label indicates that the board surface temperature may exceed 70°C when the ambient temperature is higher than 55°C. If surface temperature reaches this level, you need to wear protective gloves before handling the board. Issue 01 (2011-10-30)

3.11 EM6T/EM6TA/EM6F/EM6FA The EM6T/EM6F/EM6TA/EM6FA is an FE/GE interface board, which provides four FE electrical ports and two GE ports. The EM6T/EM6TA has similar functions to the EM6F/ EM6FA. The only difference is as follows: The GE ports on the EM6T/EM6TA use fixed electrical ports whereas the GE ports on the EM6F/EM6FA use the SFP modules and therefore can function as two FE/GE optical or GE electrical ports. The GE electrical ports on the EM6F/EM6FA and the EM6T/EM6TA are compatible with the FE electrical ports. NOTE

EM6TA/EM6FA boards have the same functions as EM6T/EM6F boards. The only difference is that EM6TA/EM6FA boards reserve hardware resources for the IEEE 1588v2 function.

3.11.1 Version Description The functional version of the EM6T/EM6F/EM6TA/EM6FA is SL91.

3.11.2 Functions and Features The EM6T/EM6TA/EM6F/EM6FA receives/transmits, processes, and converges four FE signals and two GE signals. The GE port on the EM6F/EM6FA can receive/transmit 2xFE optical signals using FE small form-factor pluggable (SFP) optical modules. Table 3-167 lists the functions and features that the EM6T/EM6TA/EM6F/EM6FA supports. The EM6T/EM6TA/EM6F/EM6FA needs to work with the packet switching unit of the system control, switching, and timing board to implement Ethernet service functions.

Straight-through cables are used between MDIs and MDI-Xs, and crossover cables are used between MDIs or between MDI-Xs. The only difference between straight-through cables and crossover cables is with regard to the pin assignment. The NMS/COM port, NE cascading port, and Ethernet electrical service ports of the OptiX RTN 910 support the MDI, MDI-X, and auto-MDI/MDI-X modes. Straight-through cables and crossover cables can be used to connect the NMS/COM port, EXT port, and Ethernet electrical service ports to MDIs or MDI-Xs.

Proxy ARP

Disabled

Disabled

l The proxy ARP enables the NEs in the same network segment but different domains to communicate with each other.

l To realize communication between such NEs, the source NE sends the ARP broadcast packet to address the route to the destination NE. The NE with the proxy ARP function enabled checks the routing table after sensing the ARP broadcast packet. If the routing table contains the destination address that the ARP broadcast packet looks for, the NE returns an ARP spoofing packet, which enables the NE that sends the ARP broadcast packet to consider that the MAC address of the NE that returns the ARP spoofing packet is the MAC address of the destination NE. In this manner, the packet that is to be sent to the destination NE is first sent to the NE with the proxy ARP function enabled and then forwarded to the destination NE.

0

l This parameter specifies the duration of the hold-off time. l When a line is faulty, SNCP switching can be performed on the NE after a delay of time to prevent the situation where the NE performs SNCP switching and other protection switching at the same time. l Hold-off Time(100ms) is generally set to prevent SNCP protection switching, when SNCP works with N+1 protection. Hold-off Time(100ms) must be longer than the switching time of any protection mode that works with SNCP. Generally, Hold-off Time(100ms) is set to 200 ms. l When SNCP works with 1+1 FD/SD, trigger conditions for HSM switching or SNCP switching trigger HSM switching but do not trigger SNCP switching. Therefore, Hold-off Time(100ms) does not need to be set in this case. l The switching time of 1+1 HSB/FD/SD protection is much longer than that of SNCP. Therefore, to shorten service interruptions, it is recommended that you do not set Hold-off Time(100ms) when SNCP works with 1+1 HSB/FD/SD protection. l If only the SNCP scheme is available, it is recommended that you set the hold-off time to 0.

0

l This parameter specifies the duration of the hold-off time. l When a line is faulty, SNCP switching can be performed on the NE after a delay of time to prevent the situation where the NE performs SNCP switching and other protection switching at the same time. l Hold-off Time(100ms) is generally set to prevent SNCP protection switching, when SNCP works with N+1 protection. Hold-off Time(100ms) must be longer than the switching time of any protection mode that works with SNCP. Generally, Hold-off Time(100ms) is set to 200 ms. l When SNCP works with 1+1 FD/SD, trigger conditions for HSM switching or SNCP switching trigger HSM switching but do not trigger SNCP switching. Therefore, Hold-off Time(100ms) does not need to be set in this case. l The switching time of 1+1 HSB/FD/SD protection is much longer than that of SNCP. Therefore, to shorten service interruptions, it is recommended that you do not set Hold-off Time(100ms) when SNCP works with 1+1 HSB/FD/SD protection. l If only the SNCP scheme is available, it is recommended that you set the hold-off time to 0.

-

This parameter specifies the VLAN ID of the sink service.

NOTE

l The VLAN ID of the UNI-UNI E-Line service can be converted after a VLAN forwarding table item is created. In this case, a service from Source Interface to Sink Interface carries the VLAN ID specified in Sink VLAN ID when the service is transmitted from Sink Interface. l The VLAN ID in a VLAN forwarding table item is converted unidirectionally and can be converted from Source VLAN ID to Sink VLAN ID only. The VLAN ID can be converted bidirectionally only when the other VLAN forwarding table item is configured reversely. l In normal cases, Ethernet services are bidirectional. Hence, you need to set bidirectional conversion of VLAN IDs.

A Parameters Description

NOTE

l Regardless of whether VLAN ID swapping is required by an E-AGGR service, a VLAN forwarding table needs to be configured, specifying the source and sink VLAN IDs of each VLAN-based service. l A VLAN forwarding table enables VLAN ID swapping for an E-AGGR service. After a VLAN forwarding table is created, a service from Source Interface will carry the VLAN ID specified in Sink VLAN ID when leaving Sink Interface. l For an E-AGGR service, the VLAN forwarding table specifies bidirectional VLAN ID swapping relationships. This means that swapping from Sink VLAN ID to Source VLAN ID and swapping from Source VLAN ID to Sink VLAN ID will be implemented once a VLAN forwarding entry for changing Source VLAN ID to Sink VLAN ID is configured. l For service aggregation from UNI ports to an NNI port, Source VLAN ID must take any of the VLAN IDs that have been configured for UNI ports. l For service aggregation from NNI ports to a UNI port, Sink VLAN ID must take any of the VLAN IDs that have been configured for UNI ports.

NOTE

l Regardless of whether VLAN ID swapping is required by an E-AGGR service, a VLAN forwarding table needs to be configured, specifying the source and sink VLAN IDs of each VLAN-based service. l A VLAN forwarding table enables VLAN ID swapping for an E-AGGR service. After a VLAN forwarding table is created, a service from Source Interface will carry the VLAN ID specified in Sink VLAN ID when leaving Sink Interface. l For an E-AGGR service, the VLAN forwarding table specifies bidirectional VLAN ID swapping relationships. This means that swapping from Sink VLAN ID to Source VLAN ID and swapping from Source VLAN ID to Sink VLAN ID will be implemented once a VLAN forwarding entry for changing Source VLAN ID to Sink VLAN ID is configured. l For service aggregation from UNI ports to an NNI port, Source VLAN ID must take any of the VLAN IDs that have been configured for UNI ports. l For service aggregation from NNI ports to a UNI port, Sink VLAN ID must take any of the VLAN IDs that have been configured for UNI ports.

l This parameter indicates or specifies the hold-off time of the ERPS hold-off timer. l The hold-off timer is used for negotiating the protection switching sequence when the ERPS coexists with other protection schemes so that the fault can be rectified in the case of other protection switching (such as LAG protection) before the ERPS occurs. When a node on the ring detects one or more new faults, it starts up the hold-off timer if the preset hold-off time is set to a value that is not 0. During the hold-off time, the fault is not reported to trigger an ERPS. When the holdoff timer times out, the node checks the link status regardless whether the fault that triggers the startup of the timer exists. If the fault exists, the node reports it to trigger an ERPS. This fault can be the same as or different from the fault that triggers the initial startup of the hold-off timer.

Guard Time(ms)

500

l This parameter indicates or specifies the guard time of the ERPS guard timer. l The nodes on the ring continuously forward the R-APS packets to the Ethernet ring. As a result, the outdated RAPS packets may exist on the ring network. After a node on the ring receives the outdated R-APS packets, an incorrect ERPS may occur. The ERPS guard timer is an R-APS timer used for preventing a node on the ring from receiving outdated R-APS packets. When a faulty node on the ring detects that the switching condition is cleared, the node starts up the guard timer and starts to forward the RAPS (NR) packets. During this period, the R-APS packets received by the node are discarded. The received R-APS packets are forwarded only after the time of the guard timer expires.

When the working channel is restored, the WTR timer of the RPL owner starts up. In addition, a signal that indicates the operation of the WTR timer is continuously output in the timing process. When the WTR timer times out and no switching request of a higher priority is received, the signal indicating the operation of the WTR timer is not transmitted. In addition, the WTR release signal is continuously output. l The WTR timer is used to prevent frequent switching caused by the unstable working channel.

Non-Sharing

l Set Load Sharing to the same value as the peer equipment. It is recommended that you set Load Sharing to Non-Sharing at both ends if the LAGs are used for protection and set Load Sharing to Sharing at both ends if the LAGs are used for increasing bandwidths.

Non-Sharing

l Sharing: Each member link of a LAG processes traffic at the same time and shares the traffic load. The sharing mode can increase a bandwidth utilization for the link. When the LAG members change, or certain links fail, the system automatically re-allocates the traffic. l Non-Sharing: Only one member link of a LAG carries traffic, and the other link is in the standby state. In this case, a hot backup mechanism is provided. When the active link of a LAG is faulty, the system activates the standby link, thus preventing link failure.

l This parameter indicates or specifies the hold-off time of the ERPS hold-off timer. l The hold-off timer is used for negotiating the protection switching sequence when the ERPS coexists with other protection schemes so that the fault can be rectified in the case of other protection switching (such as LAG protection) before the ERPS occurs. When a node on the ring detects one or more new faults, it starts up the hold-off timer if the preset hold-off time is set to a value that is not 0. During the hold-off time, the fault is not reported to trigger an ERPS. When the holdoff timer times out, the node checks the link status regardless whether the fault that triggers the startup of the timer exists. If the fault exists, the node reports it to trigger an ERPS. This fault can be the same as or different from the fault that triggers the initial startup of the hold-off timer.

Guard Time(ms)

l This parameter indicates or specifies the guard time of the ERPS guard timer. l The nodes on the ring continuously forward the R-APS packets to the Ethernet ring. As a result, the outdated RAPS packets may exist on the ring network. After a node on the ring receives the outdated R-APS packets, an incorrect ERPS may occur. The ERPS guard timer is an R-APS timer used for preventing a node on the ring from receiving outdated R-APS packets. When a faulty node on the ring detects that the switching condition is cleared, the node starts up the guard timer and starts to forward the RAPS (NR) packets. During this period, the R-APS packets received by the node are discarded. The received R-APS packets are forwarded only after the time of the guard timer expires.

LAG Type

Static

Static

l Static: A static LAG is created by the user. To add or delete a member port, you need to run the Link Aggregation Control Protocol (LACP) protocol. In a static LAG, a port can be in selected, standby, or unselected state. By running the LACP protocol, devices exchange aggregation information so that they share the same aggregation information.

Manual

l Manual: A manual LAG is created by the user. When you add or delete a member port, you need not run the LACP protocol. In a manual LAG, a port can be in the UP or DOWN state. The system determines whether to aggregate a port according to its physical state (UP or DOWN), working mode, and rate. Load Sharing

Sharing

Sharing

Non-Sharing

l Sharing: In a sharing LAG, all member ports always share the traffic load. The sharing mode can improve bandwidth utilization on a link. When the member ports are changed or some member ports fail, the traffic load of each member port is automatically re-allocated. l Non-Sharing: In a non-sharing LAG, only one member port carries the traffic load and the other member ports are in Standby state. Actually, a non-sharing LAG works in hot-standby mode. When the active port fails, the system selects a standby port to substitute for the failed port, thus preventing a link failure.

Sharing Mode

IP Sharing Mode

IP Sharing Mode

You can set this parameter only when Load Sharing is Sharing.

Revertive

l You can set this parameter only when Load Sharing is Non-Sharing.

MAC Sharing Mode Revertive Mode

Revertive Non-Revertive

l If this parameter is set to Revertive, services are automatically switched back to the working path after the working path recovers. l If this parameter is set to NonRevertive, services are still transmitted in the protection path after the working path recovers and the LAG remains the same.

The weighted proportion of these WRR queues is 1:2:4:8:16:32:64 (from priority 0 to priority 6). On the EFP8 board, the weighted proportion of these WRR queues cannot be changed. On the EMS6 board, the weighted proportion of these WRR queues can be changed. l If the traffic shaping feature of some queues is enabled, bandwidth is allocated first to the queues whose traffic shaping feature is enabled based on the CIR. The remaining bandwidth is allocated to the eight queues by using the SP+WRR algorithm.

Queue 1: WRR

WRR

Queue 2: WRR

By default, queue 8 (with the CoS priority of 7) of the EMS6 board is the SP queue, and queues 1-7 (with the respective CoS priority of 0-6) are the WRR queues and their weights are in the proportion of 1:2:8:16:32:64.

Queue 3: WRR Queue 4: WRR Queue 5: WRR Queue 6: WRR Queue 7: WRR Queue 8: SP

The scheduling principles of the SP+WRR are as follows: l A port immediately transmits the packets in the SP queue and can transmit the packets in the WRR queue only when no packets exist in the SP queue. l If multiple SP queues exist on a port, the port compares the SP queues according to their priorities (queue 8 has the highest priority and queue 1 has the lowest priority). l According to the fixed weight value, you can allocate the time slice to each WRR queue. Then, the port transmits the packets in the corresponding WRR queue in each time slice. If a WRR queue in a time slice does not contain any packets, the WRR queue removes this time slice and then transmits the packets in the corresponding WRR queue in the next time slice.

l The SSM protocol is a scheme used for synchronous management on an SDH network and indicates that the SSM is passed by the lower four bits of the S1 byte and can be exchanged between the nodes. The SSM protocol ensures that the equipment automatically selects the clock source of the highest quality and highest priority, thus preventing mutual clock tracing.

Start Standard SSM Protocol Stop SSM Protocol

l After the standard SSM protocol is started, the NE first performs the protection switching on the clock source according to the clock quality level information provided by the S1 byte. If the quality level of the clock source is the same, the NE then performs the protection switching according to the clock priority table. That is, the NE selects an unlocked clock source that is of the highest quality and highest priority from all the current available clock sources as the clock source to be synchronized and traced by the local station. l If the SSM protocol is stopped, it indicates

A Parameters Description

Parameter

Value Range

Default Value

Description

Data Output Method in Holdover Mode

Normal Data Output

Normal Data Output

l When all the reference timing signals are lost, the slave clock changes to the holdover mode. At this time, the slave clock works based on the latest frequency information stored before the reference timing signals are lost. Then, the frequency of the oscillator drifts slowly to ensure that the offset between the frequency of the slave clock and the reference frequency is very small. As a result, the impact caused by the drift is limited within the specified requirement.

Keep the Latest Data

l Normal Data Output: The slave clock works based on the latest frequency information stored before the reference timing signals are lost, and the holdover duration depends on the size of the phase-locked clock register on the equipment. The holdover duration can be up to 24 hours. l Keep the Latest Data: The slave clock works in holdover mode all the time based on the latest frequency information stored before the reference timing signals are lost.

cyclic redundancy check

A procedure used in checking for errors in data transmission. CRC error checking uses a complex calculation to generate a number based on the data transmitted. The sending device performs the calculation before transmission and includes it in the packet that it sends to the receiving device. The receiving device repeats the same calculation after transmission. If both devices obtain the same result, it is assumed that the transmission was error free. The procedure is known as a redundancy check because each transmission includes not only data but extra (redundant) error-checking values.

T tail drop

A type of QoS. When a queue within a network router reaches its maximum length, packet drops can occur. When a packet drop occurs, connection-based protocols such as TCP slow down their transmission rates in an attempt to let queued packets be serviced, thereby letting the queue empty. This is also known as tail drop because packets are dropped from the input end (tail) of the queue.

UDP provides application programs with the unreliable connectionless packet delivery service. Therefore, UDP messages can be lost, duplicated, delayed, or delivered out of order. UDP is used to try to transmit the data packet, that is, the destination device does not actively confirm whether the correct data packet is received.

user network interface The interface between user equipment and private or public network equipment (for example, ATM switches).

V V-UNI

See virtual user-network interface

variable bit rate

One of the traffic classes used by ATM (Asynchronous Transfer Mode). Unlike a permanent CBR (Constant Bit Rate) channel, a VBR data stream varies in bandwidth and is better suited to non real time transfers than to real-time streams such as voice calls.

VCI

See virtual channel identifier

VCTRUNK

A virtual concatenation group applied in data service mapping, also called the internal port of a data service processing board

virtual channel connection

The VC logical trail that carries data between two end points in an ATM network. A logical grouping of multiple virtual channel connections into one virtual connection.

virtual channel identifier

A 16-bit field in the header of an ATM cell. The VCI, together with the VPI, is used to identify the next destination of a cell as it passes through a series of ATM switches on its way to its destination.

virtual concatenation group

A group of co-located member trail termination functions that are connected to the same virtual concatenation link

virtual container

The information structure used to support path layer connections in the SDH. It consists of information payload and path Overhead (POH) information fields organized in a block frame structure which repeats every 125 or 500 μs.

virtual local area network

A logical grouping of two or more nodes which are not necessarily on the same physical network segment but which share the same IP network number. This is often associated with switched Ethernet.

virtual path identifier

The field in the Asynchronous Transfer Mode (ATM) cell header that identifies to which virtual path the cell belongs.

virtual private LAN service

A type of point-to-multipoint L2VPN service provided over the public network. VPLS enables geographically isolated user sites to communicate with each other through the MAN/WAN as if they are on the same LAN.

virtual private network A system configuration, where the subscriber is able to build a private network via connections to different network switches that may include private network capabilities. virtual route forward

VRF performs the function of establishing multiple virtual routing devices on one actual routing device. That is, the L3 interfaces of the device are distributed to different VRFs, performing the function of establishing multiple virtual route forwarding instances on the device.

virtual user-network interface

A virtual user-network interface, works as an action point to perform service classification and traffic control in HQoS.

VLAN

See virtual local area network

voice over IP

An IP telephony term for a set of facilities used to manage the delivery of voice information over the Internet. VoIP involves sending voice information in a digital form in discrete packets rather than by using the traditional circuit-committed protocols of the public switched telephone network (PSTN).

W wait to restore

The number of minutes to wait before services are switched back to the working line.

WAN

See wide area network

Web LCT

The local maintenance terminal of a transport network, which is located on the NE management layer of the transport network

weighted fair queuing

A fair queue scheduling algorithm based on bandwidth allocation weights. This scheduling algorithm allocates the total bandwidth of an interface to queues, according to their weights and schedules the queues cyclically. In this manner, packets of all priority queues can be scheduled.

weighted random early A packet loss algorithm used for congestion avoidance. It can prevent the global TCP detection synchronization caused by traditional tail-drop. WRED is favorable for the high-priority packet when calculating the packet loss ratio. weighted round Robin N/A WFQ

See weighted fair queuing

wide area network

A network composed of computers which are far away from each other which are physically connected through specific protocols. WAN covers a broad area, such as a province, a state or even a country.
