Functional Description This topic provides background information about and describes the operation of the VSATPlus 3 network.

TDMA Overview

The VSATPlus 3 system makes maximum use of satellite bandwidth by combining Time-Division Multiple Access (TDMA) and Frequency Hopping (FHOP) techniques. Each station transmits short, high-speed bursts, one at a time for a given frequency. To do this, each earth station temporarily buffers its user information, and then it periodically transmits that information to the satellite in a short burst. Each burst is timed, or synchronized, so the bursts received on a given frequency by the satellite are closely spaced in time but never overlap. This approach assures that the satellite amplifies and retransmits bursts to all nodes. As a result, each VSATPlus 3 Terminal can receive information from all other earth stations with no additional hardware. This factor is significant in making TDMA lower in cost and more flexible than other multiple-access methods. The terms Node and Station have the following specific definitions: • Node – Addressable point on a network that is associated with one TDMA terminal • Station – Geographical location of nodes including the Radio Frequency (RF) equipment Although a VSATPlus 3 network is hubless, it does contain primary reference and non-reference nodes: • The VSATPlus 3 Terminal that is the primary reference node provides the primary timing reference signal that defines the start of the signaling channels, the start of the first frame, and the start of the superframe. • The VSATPlus 3 network contains a primary and a secondary reference node that may be geographically distant from each other. The secondary reference node transmits the reference signal when the primary node stops transmitting the signal. • The other VSATPlus 3 Terminals are the non-reference nodes. • Any node can become a reference node. The terminal hardware is the same at all nodes.

VSATPlus 3 > Overview > Functional Description

Frame Structure Bursts are arranged in frames. Each terminal is allotted bursts in the frame to transmit traffic. A frame is made up of three types of bursts: • Network Broadcast Channel (NBC) burst – Transmitted by the primary reference node to manage network configuration, status, and bandwidth allocation • Common Signaling Channel (CSC) burst – Used by each node to transmit to the primary reference node, configure and synchronize to the network, respond to queries, provide status, and request bandwidth allocation. Each node has one or more CSC slots in the superframe. • Customer information bursts – Includes information from a single node. Information is normally contained within IP packets that are routed to the Ethernet port of the destination terminal. Simplified Frame Structure Frame Guards

The parameter values are the same on all nodes. Command network reconfiguration – For example, to redefine which node is the primary reference node and which is the secondary reference node Status inquiry – The response to this inquiry is contained in the CSC bursts from each node. Bandwidth allocation

Characteristics of a superframe include: • The number of frames present is sufficient to include a CSC burst from each node. • The number of frames in the superframe and the number of CSCs per frame determine the maximum number of nodes that can be supported in the network. Each node tracks the superframe count that is transmitted by the primary reference node. This count is used to make sure that all nodes add or delete bursts at the same frame boundary.

TDMA Acquisition

TDMA acquisition is the process that a node uses to join the network. Acquisition has two phases: • Receive Acquisition – The node finds the reference signal that indicates the start of a superframe and frame. During receive acquisition, the terminal sweeps through time, frequency, and amplitude as it searches for the reference signal. • Transmit Acquisition – When the terminal finds the reference signal, it starts the transmit acquisition process. The terminal determines the time to transmit to the satellite based on the distance to the satellite. To determine transmission timing, the terminal uses the configured locations of the terminal and the satellite, along with the distance estimate provided by the primary reference. The center of a TDMA network is the satellite. Bursts must arrive at the satellite within two symbols from their expected arrival time. Otherwise, the integrity of the network is at risk if TDMA channels start to overlap. All terminals, except for the primary reference node, must complete receive acquisition and then transmit acquisition. The primary reference does not need to complete transmit acquisition because it is the first node to start in a network. It can start transmitting at an arbitrary time, and needs only to perform receive acquisition on its own signal.

VSATPlus 3 > Overview > Functional Description

Primary Reference Node Acquisition The Primary Reference Node provides network timing in the VSATPlus 3 network. The Primary Reference Node is the first node that is acquired in the network. Any node in the network can become the primary reference node, but only one node is the primary reference node at any time. During acquisition and synchronization: a The Primary Reference Node transmits and receives back its own reference (REF) bursts. b

The Primary Reference Node measures the round-trip satellite delay between the transmit and receipt of reference bursts. The round-trip time is estimated from the geographic coordinates that are configured at the terminal, and from the coordinates of the satellite. The difference between the estimated and the measured round-trip times indicates the distance the satellite has moved in the center of its orbit. The primary reference node broadcasts the difference to the other nodes in the network so that they can complete transmit acquisition more quickly.

Correction for any timing shifts caused by differences in local oscillators and satellite motion (Doppler shift) is done automatically.

Primary and Secondary References

In a VSATPlus 3 network, the primary node provides the reference signal that indicates the start of the superframe. You can configure one other node to be the secondary reference node. The secondary reference node monitors the primary reference signal. If the primary reference signal stops, then the secondary reference node starts to transmit the reference signal in the second reference slot. The secondary reference node becomes the primary reference node and takes control of the NBC channels. After the secondary becomes the primary reference node, you can assign a new secondary reference node in the network. First and Second Reference Slots Frame Superframes

Bandwidth Pool

As shown in the figure, Superframe, Frame, and Burst Structure on page 17, the timeslots from Carrier 0 to Carrier n are aligned over one another. This bandwidth pool is managed by the Bandwidth on Demand (BoD) server that is at the primary reference node. When you add a new carrier to the VSATPlus 3 network, it is automatically added to the bandwidth pool, and the BoD server manages the new carrier along with the previously configured carriers. For detailed information about the rules to follow when you allocate bandwidth, see Configuring IP Links on page 48.

VSATPlus 3 > Overview > Configuration Overview

Configuration Overview To configure a VSATPlus 3 network: • First, you install and configure the VSATPlus 3 Terminal that will be the primary reference node. This node provides the primary timing reference signal that defines the start of the signaling channels, the start of the first frame, and the start of the superframe. • Then, you install and configure the other VSATPlus 3 Terminals that will be the non-reference nodes. Once the network is operating, any node in the network can become the primary reference node.

Primary Reference Node

On the primary reference node, you configure the parameters common to all nodes. The system automatically activates and downloads parameter lists to all nodes in the network. Nodes that are not operating during a download of new parameters automatically receive the parameter lists when they join the network. These parameter lists are distributed to each terminal by way of the signaling channels – the NBC and CSC. You can configure IP routes, IP links, and carriers when you configure the primary reference node. Alternatively, you can configure these parameters after you install and configure remote nodes. • Configuring the Primary Reference Terminal on page 36 • Configuring the Global Network on page 42

Non-Reference Nodes

When you configure a terminal at a non-reference node, first you configure the node locally with the minimum number of parameters it needs to join the network. When the terminal joins the network, it receives the global parameters that are common to all nodes. These include the IP routes, IP links, and carriers that are configured on the primary reference node. • Configuring a Non-Reference Terminal on page 54

QoS Configuration

VSATPlus 3 Terminals are pre-configured with a default set of QoS rules, so you may not need need to configure QoS in order to make the VSATPlus 3 network operational. If the default QoS rules are not suitable, you can edit the rules after the network is operating. • Configuring QoS Rules on page 59

VSATPlus 3 > Installation and Configuration > Configuring the Primary Reference Terminal

Configuring the Primary Reference Terminal This topic describes how to connect to the web-based user interface and configure the VSATPlus 3 Terminal that serves as the primary reference node in a network. The primary reference node is the first node that starts in a VSATPlus 3 network. It provides the primary timing reference signal that defines the start of the signaling channels, and the start of the satellite frame and superframe. On the primary reference node, you configure the parameters common to all nodes. The system automatically activates and downloads the global parameter lists to all nodes in the network. Nodes that are not operating will download the lists when they join the network. These parameter lists are distributed to each terminal over the signaling channel – the NBC and CSC. After the lists are distributed, and the configuration information from the primary reference is replicated throughout the network, any other terminal can become the primary reference node if needed. The web-based user interface is identical on all nodes in the network. You can edit and save global parameters for the network – IP Routes, IP Links, and Carriers – only on the primary node. However, you can display these parameters from a non-reference terminal. Note: • For background information about the configuration of a VSATPlus 3 network and a summary of which parameters you configure at the primary reference and non-reference nodes, see Configuration Overview on page 24.

Before you start:

Configuring the Initial Network Parameters

Select Configure > Network.

! CAUTION Risk of Loss of Connectivity If you change network parameters when the network is operating, you can break connectivity between nodes in the network. 2

The following parameters prepare the initial configuration. These parameters must be the same on every node in the network. Configure the following on the primary reference node:

Network Size Enter the number of terminals in the network. The system uses this parameter to define the number of CSCs that are needed for signaling. • The range of values is from 1 to 1000. • The maximum number of terminals is limited also by the number of signaling channels. Each terminal requires at least one CSC channel, so the number of terminals cannot be greater than the superframe size multiplied by the number of CSC bursts for each frame.

Symbol Rate Enter the number of symbols that occur each second. Each symbol carries 2 bits for QPSK, or 3 bits for 8PSK. • The range of values is from 0.128 to 5.0 MegaSymbols/second.

Frame Time Defines the duration of one TDMA frame in the network: • Select 20, 30, or 40 ms frames.

Secondary Ref Terminal Note: • You can configure the secondary reference node only from the primary reference node. It becomes effective only when the primary reference node is installed and configured. Defines the node that operates as the secondary reference node in the network. • The secondary reference transmits the reference signal if the primary node stops transmitting the signal. • The range of values is from 1 to the maximum number of nodes that are in the network.

! CAUTION Risk of Network Outage Do not define the secondary reference node to be on the same terminal as the primary reference node. Also, make sure that the secondary reference node is geographically distant from the primary reference node. If the two reference nodes are close together, interference (for example, from a solar outage) can affect both terminals at the same time and bring down the network. In this case, the network loses the reference signal.

TPC parameters Turbo Product Code (TPC) parameters display detailed information about the type of Turbo Coding that is used in data bursts. Each coding type has trade offs between coding gain and bandwidth granularity of the bandwidth pool. Columns: TPC Codec – The TPC codec (encoder-decoder) that is used for data bursts • You cannot edit this parameter for the CSC channel. It is displayed for information only. • You can edit this parameter for the data bursts. # Blocks • The number of blocks in each burst • For CSC only, enter 2 for symbol rates above 2.5 MegaSymbols/second. # Bursts For DATA bursts, the system computes the number of bursts. For CSC only: • The number of CSC columns or bursts at the start of each frame • The default value is 1. You can enter a different value. • The number of CSC bursts must be the same on every terminal. Signal Modulation – The modulation type that is used for data traffic: • Select QPSK or 8PSK. Note: • If the DATA bursts use 8PSK modulation, the signaling bursts (NBC, CSC) continue to use QPSK.

VSATPlus 3 > Installation and Configuration > Configuring the Primary Reference Terminal Note: • Define the VSATPlus 3 carriers only on the Primary Reference node because the carriers are global to the VSATPlus 3 network. Configure the ODU Frequency Offset on the local VSATPlus 3 Terminals to add to the global value of the carrier frequency definitions and adapt to the local ODU frequency – Configuring Terminal Parameters at a NonReference Terminal on page 55. • The 70 MHz modem filters pass frequencies only in the range from 50 MHz to 90 MHz, and cannot transmit or receive frequencies outside of that range. If a combination of the carrier frequency plus the ODU frequency offset falls outside of this range for any carriers, the terminal switches to the In-Network state. In that state, the terminal releases all bandwidth and remains manageable from the Primary VSATPlus 3 Terminal over the NBC and CSC. The operator at the Primary terminal can detect the change on the remote terminal from the On-line to InNetwork state. Then, delete the carrier that was just added to bring the terminal back into the On-line state. Note that when the terminal switches to the In-Network state, you cannot manage it over the satellite link from the browser because all bandwidth has been released. However, the browser remains available from the Terrestrial port. When a carrier is defined outside the frequency range, the log records the alarm, "Carrier X is beyond limit when local ODU offset applied." • For a CW (continuous wave test carrier), the ODU Frequency Offset also applies.

L-Band parameters Only for L-Band, define the following parameters for both transmit (Tx) and receive (Rx) directions. For a detailed description, see Assigning Carrier Frequencies – L-Band Center Frequency on page 72. Receive and Transmit Center Frequency • Define the center frequency of a 40 MHz band. The center frequency must be between 950 MHz and 1525 MHz. Note: • The center frequency that you enter is the center frequency that the modem uses to transmit and receive, and it must match the frequency that the ODU equipment expects. Receive and Transmit Spectral Inversion • Activates spectral inversion on the transmit or receive links. Receive and Transmit 10 MHz Reference Output • Select to send a 10 MHz reference signal to ODU equipment. Receive and Transmit 24 V DC Output • Select to send 24 V DC to ODU equipment.

Configuring the Global Network You can display the global parameters at every node, but you can edit them only at the primary reference node. If you change global parameters at a nonreference node, the system detects the change, and overwrites the changes by a download of the original values from the primary reference node. Global parameters affect every node in the network and are the same on every terminal. Make sure that you configure the global parameters on the primary reference node. The primary reference node distributes the global parameters to every node in the network over the NBC or CSC signaling channel.

Default Route 7

PolarSat

How you configure a terminal depends on whether the default route (address/CIDR: 0.0.0.0/0) of the terminal is on the LAN or over-the-air (satellite). • When the default route is on the LAN side of the terminal, add another IP Route entry to configure the default route to the associated Gateway IP address. The entry is a Route type. • When the default route is over the satellite side, configure the route in the Default Terminal field of the Terminal entry.

VSATPlus 3 Terminal

Installation and Operation Guide

43

VSATPlus 3 > Installation and Configuration > Configuring the Global Network LAN Gateway Default Route – A default route (0.0.0.0/0) to a LAN gateway is typical for nodes that are at the same location as Internet gateways. These nodes provide access to the Internet for the other VSATPlus 3 Terminals in the network. When you configure a terminal with a default LAN gateway, make sure that the Default terminal is set to – (dash = none). This setting indicates that the terminal does not have a default route that is over-the-air.

! CAUTION Risk of Unexpected Behavior If you configure both a default route over a LAN gateway and a default route over-the-air, you can cause routing loops and unexpected routing behavior. In the example network, Entry 1 indicates that Node 15 has a Default Terminal value of –, which means that the default IP Gateway is on the LAN side, rather than over-the-air. As a result, Terminal 15 must have another entry – entry 2 of type Route – to specify the default route on the LAN side. Default Terminal (over-the-air) – If you set the Default Terminal to a nonzero value, the terminal configures a default route over-the-air to the specified terminal. To remove a default route, set the Default Terminal to – (dash). In the example network, Terminals 6 and 10 are configured to use Terminal 15 as the default gateway. Any IP packet that arrives at these terminals on their LAN port that does not match a specific route is forwarded over-the-air to Node 15.

Dynamic Routing

If you enable dynamic routing, you must enable it over both the satellite (overthe-air) and over the LAN interface of each terminal.

OSPF Notes • •

For most networks, set both the LAN and satellite OSPF areas to 0.0.0.0 You do not need to enable OSPF on the LAN side of terminals that do not have other OSPF-enabled routers. This is typical at branch office or Small Office Home Office (SOHO) sites.

Enabling OSPF on the Satellite Interface 14 Over-The-Air Routing – The over-the-air routing is common to all terminals: a For each terminal, click Configure > Route. b

Set Routing Protocol to OSPF.

c

Area – Configure the OSPF Area in dotted decimal notation. To configure the Air segment to be part of the OSPF backbone area, use 0.0.0.0

d

Cost Over Satellite – Set a cost for the satellite segment. OSPF selects a path through the network that has the lowest cost. If the VSATPlus 3 network is being used as a backup network, set the cost to be higher than any terrestrial pathways. If the VSATPlus 3 network is the only network that connects remote sites, the cost is irrelevant.

e

Enable Static Route Redistribution – Select to allow OSPF routers to see static routes that are defined at the terminal. Otherwise, configured static routes are visible only from the VSATPlus 3 Terminal where they are defined.

f

Disable TCP Accelerator Globally – Select to correctly balance TCP traffic flow. With OSPF and depending on the network topology, some routes may be asymmetric where the forward path is different from the reverse path. If this occurs, the TCP accelerator does not work. In this case, disable the TCP accelerator globally on all terminals.

b

Set Routing Protocol to OSPF.

c

Configure the OSPF Area in dotted decimal notation. To configure the LAN segment to be part of the OSPF backbone area, use 0.0.0.0

d

Set a cost for the LAN segment. The value depends on the reference bandwidth used by other routers on the LAN segment. If other routers use 1,000,000,000 (1 Gbps Ethernet), set the LAN cost to 10 to represent the 100 Mbps fast Ethernet connection of the VSATPlus 3 Terminal. If the LAN routers use 100,000,000 (100 Mbps Fast Ethernet), set the cost to 1.

e

Click Save the Configuration.

16 To configure IP Links, click Configure > Link. An IP Link is a connection from one node to another. The direction of the connection is important. Normally, two nodes have a pair of IP links, one link for each direction: A to B and B to A. Initially, an IP link has no allocated bandwidth. As packets arrive, the node allocates timeslots from the bandwidth pool, and transmits packets to the destination node. For each IP link, you can define the following parameters:

VSATPlus 3 Terminal

Revision 08, March 2012

Final

VSATPlus 3 > Installation and Configuration > Configuring the Global Network

MIN The minimum bandwidth (MIN) remains allocated while the two nodes are up, even if no traffic needs this bandwidth. MIN treats pre-assigned bandwidth in a similar manner to with Permanently Assigned Multiple Access (PAMA). • If one of the nodes on the link goes down, then the bandwidth is released to the bandwidth pool. When the system detects that the two nodes are up, it allocates the MIN bandwidth again. • The range for the MIN parameter is from 0 to the maximum number of bursts on the carrier. The MIN must be less than or equal to the CIR.

CIR The CIR defines the bandwidth to allocate to the link when the traffic load needs it. • The system allocates bandwidth in priority up to the limit of CIR, and guarantees bandwidth only when the network is not over-subscribed. • The range for CIR is from MIN to the maximum number of bursts on a carrier. • The value of CIR always includes the value of MIN.

EIR The EIR is bandwidth in excess of the CIR that the system can allocate whenever bandwidth is available in the bandwidth pool. • The total bandwidth that the system can allocate to a link is CIR + EIR. The total bandwidth is not MIN + CIR + EIR. • The range for EIR is from 0 up to the maximum number of bursts on a carrier. However, the sum of CIR + EIR must be less than or equal to the maximum number of bursts on a carrier. Note: • The system allocates bandwidth in units of bursts. The definition of the bandwidth pool specifies the burst size. The MIN, CIR, and EIR are in units of bits-per-second (bps), and the BoD server rounds up the burst size to the nearest unit of burst. • In a network of n terminals, a fully-meshed network can have many connections. You do not have to define the MIN, CIR, and EIR parameters for each of the links. Instead, you can define explicit parameters for an IP Link, and then define default IP Link parameters for any link without explicitly defined parameters. • The MIN, CIR, and EIR Bandwidth are allocated in a pro-rated manner. If the network is oversubscribed, then each link has the same percentage of MIN, CIR, and EIR parameters. • The CIR bandwidth is always allocated first and released last. 17 In addition to the MIN, CIR, and EIR parameters, you can configure the following Advanced Parameters to control the bandwidth allocation and release:

Low Bandwidth Threshold The Low Bandwidth Threshold is a percentage of the currently allocated bandwidth that defines when to start to release bandwidth. • When the usage of the currently allocated bandwidth decreases below this threshold, and during the last N seconds that you define in the Decrease Timer, the system starts to release bandwidth. • For example, if the Decrease Timer is 6 seconds, and the Low Bandwidth Threshold is 35 %, the system releases bandwidth every 6 seconds when the usage of the currently allocated bandwidth is below 35 %.

PolarSat

VSATPlus 3 Terminal

Installation and Operation Guide

49

VSATPlus 3 > Installation and Configuration > Configuring the Global Network

High Bandwidth Threshold The High Bandwidth Threshold is a percentage of the currently allocated bandwidth that defines when to allocate more bandwidth, up to the limit of CIR + EIR. • When the usage of the currently allocated bandwidth increases above this threshold for a sampling interval of approximately 2 seconds, the Bandwidth Manager requests more bandwidth.

CIR Increase Ratio and CIR Decrease Ratio The CIR Increase Ratio and CIR Decrease Ratio together define the percentage of CIR that gets allocated and released for every request. • For example, in networks where the configured CIR is small – for example, 64 kbps – the system can allocate CIR entirely to 100 %, as soon as the first packet arrives on the link. • Conversely, in networks where the configured CIR is large, the system can allocate the CIR gradually until the CIR limit is reached. Then, the system starts to allocate EIR bandwidth, if the EIR is greater than 0. • Similarly, you can define the amount (in %) by which to release the bandwidth.

EIR Increase Ratio and EIR Decrease Ratio The EIR Increase Ratio and EIR Decrease Ratio together configure the amount of bandwidth to allocate or release from the excess bandwidth in the bandwidth pool. • Often, IP Links can be configured with a small CIR – for example, 32 or 64 kbps – and a large EIR (as large as the carrier permits). This allows multiple IP Links to share the excess bandwidth in the pool. • These two parameters configure the percentage of the EIR that is allocated and released when thresholds are crossed. Since the EIR can represent a large amount of bandwidth, the bandwidth increase can be small – for example, 10 % – while bandwidth decreases can be done more rapidly – for example, 40% each time.

Decrease Timer The Decrease Timer sets the amount of time that the bandwidth usage is below the Low Bandwidth Threshold, before the system starts to decrease the bandwidth. • PolarSat recommends that you set the value to 6 seconds or more, but no less than 6 seconds. 18 Click Save the Configuration.

Configuring Multicast Links

Multicast links are configured on and controlled from the Primary Reference terminal for the entire network. If you need to configure or enable a multicast link remotely, remotely connect over the satellite link to the Web interface of the reference terminal. Then, you can control (enable or disable) the multicast links. In general, you first configure a multicast link and save the configuration. Then, you enable the multicast link and save the configuration. You cannot change the configuration of an active multicast link. First, you must disable the active multicast link. Then, you can change the configuration. Multicast traffic has a Time-to-Live (TTL) parameter that defines the maximum number of routers that the multicast packets traverse. To send multicast packets over a satellite network, set the TTL to at least 3, because the TTL count decreases by 2 for each satellite link (between a pair of terminals).

! CAUTION Risk of Signal Loss Multicast links have higher priority than unicast links. When multicast links are enabled, the system allocates bursts to the multicast links. If needed, this removes bursts from the unicast links and can disrupt the unicast traffic. The bandwidth for multicast links is either all allocated or not at all. Multicast links do not have a partial amount of bandwidth allocated. 24 Select Configure > Multicast.

VSATPlus 3 > Installation and Configuration > Configuring a Non-Reference Terminal

Configuring a Non-Reference Terminal When you configure a non-reference VSATPlus 3 Terminal, first you configure the node locally with the minimum number of parameters it needs to join the network. Then, the terminal downloads from the primary reference terminal the parameters that are common to all nodes. These parameters are called the parameter lists or the lists. The network and terminal parameters are stored locally on each terminal. You can configure these parameters from the web-based user interface either from a remote node over the satellite link, or from the LAN port at the terminal. Note: • For background information about the configuration of a VSATPlus 3 network and a summary of which parameters you configure at the primary reference and non-reference nodes, see Configuration Overview on page 24.

Before you start: • • • •

Configure the VSATPlus 3 Terminal that is the primary reference terminal – Configuring the Primary Reference Terminal on page 36. Configure the network parameters – Configuring the Global Network on page 42. Install the VSATPlus 3 Terminal that will be the non-reference terminal – Installing a VSATPlus 3 Terminal on page 32. Connect to the user interface for the terminal, see Connecting to the User Interface on page 35.

! CAUTION Risk of Failed Configuration Because the VSATPlus 3 Terminal ships from the factory with a preconfigured IP address of 192.168.200.1, you cannot configure multiple terminals on the same LAN. If you need to connect the terminals on an IF loop (that is, not over the satellite link), make sure that the terminals are on different LANs.

Configuring Network Parameters at a Non-Reference Terminal

1

Select Configure > Network.

2

Configure the following parameters to prepare the initial configuration. These parameters must be the same on every node in the network, but you must enter them on each terminal to get the network to recognize the terminal, and so that the terminal acquires the network.

Network Size Enter the number of terminals in the network • The system uses this parameter to define the number of CSCs that are needed for signaling (NBC and CSC bursts). • The range of values is from 1 to 1000. • The value must be the same on all terminals in the network.

Symbol Rate • •

Enter the number of symbols that occur each second. Each symbol carries 2 bits for QPSK, or 3 bits for 8PSK. The range of values is from 128,000 to 5,000,000 symbols/second.

IF Type The Intermediate Frequency (IF) is defined by the modem hardware signature. • The possible values are 70 MHz or L-Band.

Signaling Carrier Frequency This parameter is the IF frequency of the signaling carrier of the network. • Enter the center frequency of the carrier. This parameter is the same as on the primary reference terminal. • For L-Band, the center frequency must be between 950 MHz and 1525 MHz, and must be within +/- 20 MHz of the Rx Center frequency. • For 70 MHz, the center frequency must be between 50 MHz and 90 MHz. ODU Frequency Offset • For 70 MHz modems, enter a frequency offset to compensate for any frequency offset of the local ODU. The range is from -20 MHz to +20 MHz. The default is 0. The same offset applies to both TX and RX directions. Note: • Define the VSATPlus 3 carriers only on the Primary Reference node because the carriers are global to the VSATPlus 3 network. Configure the ODU Frequency Offset on the local VSATPlus 3 Terminals to add to the global value of the carrier frequency definitions and adapt to the local ODU frequency – Configuring Terminal Parameters at the Primary Reference Terminal on page 38.

L-Band parameters Only for L-Band, define the following parameters for both transmit and receive directions. For a detailed description, see Assigning Carrier Frequencies – L-Band Center Frequency on page 72. Receive and Transmit Center Frequency • Define the center frequency of a 40 MHz band. The center frequency must be between 950 MHz and 1525 MHz. Note: • When you use spectral inversion, the center frequency that you enter is the center frequency that the modem uses to transmit and receive.

You can configure and enable Simple Network Management Protocol (SNMP) on any terminal that will be polled by an SNMP console. When enabled, an SNMP Agent starts on the terminal and listens for SNMP requests. The SNMP consoles are third-party modules not provided by PolarSat. VSATPlus 3 supports version 2c of the SNMP protocol. The Management Information Base (MIB) defines the list of parameters to query from a VSATPlus 3 Terminal. The details of the parameters in the MIB are in the file POLARSAT-VP3-MIB.txt. You can download the file and other standard MIBs that the terminal supports from: http:// /snmp Enable the SNMP Agent so that it can respond to SNMP requests. The default User Datagram Protocol (UDP) port for the Agent is 161. You can change this port number to a number between 1 and 65535. You can also define a community name of up to 20 characters. The name is case-sensitive. To enable the SNMP Agent traps to generate and send SNMP traps: Configure an IP address and community name. Enable the trap destination.

VSATPlus 3 > Installation and Configuration > Configuring QoS Rules

Configuring QoS Rules Quality of Service (QoS) rules classify IP packets and assign a transmission priority for the satellite link. The 8 priority levels are from 0 to 7; 0 is the highest priority. You cannot specify bandwidth limits on different traffic types. Normally, you do not need to configure QoS rules to make the VSATPlus 3 network operational. Predefined QoS rules allow the network to operate with a set of QoS rules. If the default QoS rules are not suitable, and after the network is operating, you can edit or delete any of the rules, or create new rules.

Predefined QoS Rules Priority

Description

0, 1

Alarms • Priority 0 and 1 do not have pre-defined rules. Typically, only alarms travel at these priorities.

2

VoIP DSCP • All IP packets that have the Differentiated Services Code Point (DSCP) field set to 46 (0x2E) for Expedited Flow (EF), or 40 (0x28) for IP precedence 5, are assigned priority 2. • The primary targets are Voice over Internet Protocol (VoIP) signaling and voice packets.

3

DNS UDP • All User Datagram Protocol (UDP) packets that have port 53 as a source or destination port are assigned priority 3. • The well known port for the Domain Name System (DNS) is 53.

4

HTTP, HTTPS, SSH • All packets for the interactive protocols HTTP, HTTPS, and Secure Shell (SSH) are assigned priority 4. • These interactive protocols use TCP sessions.

5

Non-interactive TCP • All TCP packets, other than HTTP, HTTPS, and SSH, are assigned priority 5. • Priority 5 is intended for non-interactive TCP applications, such as email transfer.

6

UDP • All UDP packets are assigned priority 6.

7

Other • All remaining packets are assigned priority 7. For example, all "ping" packets are assigned priority 7.

When a packet arrives at the terrestrial port, the system examines it for a match. It examines the packet from the first rule at the top of the list of QoS rules, then with each rule in descending order, until the packet matches the criteria specified by a rule. When there is a match, the system assigns the priority of the rule to the packet. If the packet passes through every rule without having a match, then it is assigned priority 7 (lowest priority). QoS statistics show the number of packets and number of bytes that each rule has matched.

Before you start: • • • •

Configure the VSATPlus 3 Terminal that is the primary reference terminal according to Configuring the Primary Reference Terminal on page 36. Configure the network parameters according to Configuring the Global Network on page 42. Configure the VSATPlus 3 Terminals that are the non-reference terminals according to Configuring a Non-Reference Terminal on page 54. QoS rules are not managed globally; the rules can be different on each terminal. Connect to the user interface for the terminal – Connecting to the User Interface on page 35.

Select Configure > QoS. The page displays QoS rules in descending order of processing.

2

You can create, edit, or delete rules. In the Action column, click the Edit icon for the rule.

3

Edit the Priority, Description, and Rule specification for each rule. Priority – Values from 0 to 7; 0 is the highest priority. Description – A free-text comment that explains the actual rule. The description is saved in the configuration, but is not used by the system. Enter a description to record the purpose of the rule. Rule – Contains the rule that classifies the packets. The rule associates values to the fields of the IP packet to find a match. When IP packets arrive, the system examines each to verify if any fields match values in the rule. If matched, the system assigns the packet the priority for that rule. a You can define the following fields of the IP packet in a rule: DSCP, Protocol, Source IP address or subnet, Destination IP address or subnet. b

You can define a compound rule that requires that any or all fields must match to assign a priority. Tip: • For a packet to match and be assigned the associated priority, the packet must meet the conditions defined by each of the four fields. So, if one field is not important for a rule, select the condition that all packets must meet that condition. For example, if the DSCP field is not important for a rule, select Any DSCP for that rule. This ensures that all packets meet the condition for the DSCP field, regardless of the value in that field. 4

VSATPlus 3 > Operation > Front Panel Status LEDs

Front Panel Status LEDs Each front panel LED contains one red and one green LED that can display green, yellow, or red light.

During Start-Up

1

During the terminal boot-up sequence as the terminal software loads, the LEDs are green except for one, yellow walking LED.

2

After the software is loaded and while the terminal initializes, the Status LED is yellow.

3

As the terminal acquires the network, the LEDs flash to indicate the current operation: a While the terminal tries to perform receive acquisition in the network, the SATNET led flashes yellow. This can take several seconds or minutes while the terminal sweeps frequencies for different signal amplitudes. b

During SteadyState Operation

4

While the terminal tries to perform transmit acquisition, the SATNET LED flashes green. Normally, this takes only a few seconds.

After the terminal acquires the network, it synchronizes configuration with the primary reference node, and starts normal operation, all LEDs are green.

Front Panel LED Status Indicators – Steady-state Operation LED

Color

Indication

STATUS

Green

The terminal is operating normally: • The parameter lists are up-to-date.

Yellow

The local parameter lists are out-of-date with the parameter lists on the primary reference node. • This condition is temporary, and normally disappears within a maximum time of one minute. • Normally, this condition occurs only after a terminal is installed for the first time. The terminal is acquiring the network for the first time, but does not yet have all of the updated lists.

Red

The terminal is in an error state: • An example cause is that the local terminal lost the timing reference signal to the network (deep fade).

Green

The terminal is operating normally.

Yellow

A signaling burst has data errors. The terminal detects the burst but cannot decode it successfully.

Red

A signaling burst cannot be detected. The transmitting node may in a fade or has stopped transmitting.

Green

The terminal is operating normally. • This LED does not flash as a result of the traffic that the terminal carries.

Yellow

The terminal cannot detect the data burst correctly.

VSATPlus 3 > Assigning Carrier Frequencies – L-Band Center Frequency

Assigning Carrier Frequencies – L-Band Center Frequency Carrier frequencies in VSATPlus 3 networks are defined as offsets relative to the center frequency of the transponder. This allows a mix of 70 MHz and L-Band terminal types to share a common carrier configuration, with each carrier defined by an offset. The frequencies can be VHF (70 MHz) or L-Band. To participate in the network, the center frequency of the terminal must be configured correctly: • For 70 MHz terminals, no setup is required, because the center frequency is 70 MHz. • For L-Band terminals, the center frequency must be set correctly on both Tx and Rx sides.

Mixed network of 70 MHz and L-Band terminals

In a mixed network, the center frequencies must be consistent between the 70 MHz terminals and the L-Band terminals. 1

First, determine the RF frequencies that correspond to a 70 MHz carrier. Do this for both Rx and Tx sides.

2

The L-Band center frequencies (fCF_TX (transmit) and fCF_RX (receive) in the following formula) for a terminal must correspond, and are calculated from the value of the Local Oscillators (LO) for the Low Noise Block (LNB) (fLO_LNB) and Block Up-Converter (BUC) (fLO_BUC). If the ODU equipment is non-inverting, calculate the frequencies by: • fCF_TX = fRF_UL – fLO_BUC • fCF_RX = fRF_DL – fLO_LNB If the equipment is inverting, calculate the frequencies by: • fCF_TX = fLO_BUC – fRF_UL • fCF_RX = fLO_LNB – fRF_DL Where: • fRF_UL – RF frequency of the Up Link • fRF_DL – RF frequency of the Down Link • fLO_BUC – LO frequency of the BUC • fLO_LNB – LO frequency of the LNB • fCF_TX – Center frequency for TX • fCF_RX – Center frequency for RX When the L-Band center frequencies are well configured, a carrier configured with an offset of 0 MHz, appears at 70 MHz on the 70 MHz terminals, and at the L-Band center frequency on L-Band terminals.

L-Band-only network

If a network consists only of L-Band terminals, either: • Proceed as in the Mixed network of 70 MHz and L-Band terminals. Set the central frequency to the value that corresponds to a 70 MHz carrier transmitted by a 70 MHz terminal, as if such a terminal is in the network. This allows the future addition of a 70 MHz terminal to the network without re-configuration of the network. • Otherwise, select arbitrary RF center frequencies (fRF_UL and fRF_DL) to define the center frequency in the network, and use the formulas in step 2 to calculate the corresponding L-Band center frequencies. Important: Once the RF center frequencies are selected, they apply to all terminals in the network and cannot be changed easily. Select the RF center frequencies, according to the following constraints: • Normally, the frequencies are a multiple of 1 MHz. However, if the uplink and downlink frequency of the transponder are not separated by a multiple of MHz, you can configure only the TX L-Band center frequency as a fraction of MHz. • fRF_UL corresponds to fRF_DL when down-converted by the transponder. • Choose the frequency so that all carriers in the network are within +/– 20 MHz of the center frequency.

VSATPlus 3 > Assigning Carrier Frequencies – L-Band Center Frequency Note: • The chosen RF center frequencies become a reference for the network. All carriers are configured as offsets from this reference. Use the same RF center frequency on all terminals in a network when you calculate the L-Band center frequency. For example: • fRF_UL = 6042 MHz = RF frequency of the Up Link of the network • fRF_DL = 3817 MHz = RF frequency of the Down Link of the network • fLO_BUC = 4900 MHz = LO frequency of the BUC for one site • fLO_LNB = 5150 MHz = LO frequency of the LNB (Rx spectral inversion) The computed L-Band center frequencies are: • fCF_TX = 1142 MHz = L-Band center frequency for Tx • fCF_RX = 1333 MHz = L-Band center frequency for Rx
