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.

Burst Structure
Each burst includes the following:
Guard – Period of time during which no node transmits
• Assures that no bursts overlap due to the imperfect timing of transmit
bursts from one node to the next
• Compensates for differences in clock frequency between nodes and the
doppler effect (satellite motion)
Preamble – Sequence of ones and zeroes providing defined transitions for
the demodulator
• Defines where information bits are located within the burst
• Used to detect the start of a burst and estimate carrier phase, carrier
level, and symbol timing
Payload – Sequence of data that begins immediately after the preamble
and contains an integral number of turbo blocks
Tail – Segment of bursts that incrementally reduces the transmit power

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.

Superframe
Structure
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.
20
VSATPlus 3 Terminal
PolarSat
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.
01-3000-001
Final
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.
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.

After acquisition, the VSATPlus 3 Terminal must monitor its timing in
relationship to the network, particularly to the Primary Reference Node.
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.

Note:
• The primary reference node provides timing for all nodes in the network.
• A secondary reference node is the backup to the primary reference node.
The reference switchover occurs automatically. No manual intervention
is needed.
• No extra equipment is needed for a node to become the primary or
secondary reference node.
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 44.

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 Parameters on page 41
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.
•

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 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.

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

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.

01-3000-001
Final
Enter the number of frames for each superframe in the network. A
superframe is a group of frames – Superframe Structure on page 20.
• The range of values is from 10 to 60 frames/superframe.
• Typically, select 30 or 60 frames/superframe.
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.

Terminal Number
Defines the number of the terminal, and defines which CSC timeslot the
terminal uses to contact the primary reference node.
• Enter a number from 1 to the maximum number of nodes in the network.
The network can contain a maximum of 1000 nodes.
• This number cannot be zero (0).
• The number must be unique within the network. Nodes cannot use the
same number.
IF Type
The IF is defined by the modem hardware signature.
• The possible values are 70 MHz or L-Band.
• This information is not editable.
This parameter is the IF frequency of the signaling carrier of the network.
This parameter shows the center frequency for Carrier 0.
• This is the only carrier frequency that you enter at a non-reference
terminal.
• You enter the frequency of the other carriers on the Carrier tab and only
at the primary reference node. See Configuring the Carriers on page 46.
Enter the center frequency of the carrier:
• For L-Band, the center frequency must be between 950 MHz and
1525 MHz.
• For 70 MHz, the center frequency must be from 50 to 90 MHz.
• 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.

Final
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 48.
• 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 64.
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.

• If ULPC is enabled, this is the nominal transmit power when there is no
local fade.
ULPC
When enabled, UpLink Power Control (ULPC) automatically adjusts transmit
power to overcome uplink fade in order to keep the signal power constant
at the satellite. Total fade is the sum of the uplink and downlink fades. Uplink
fade is derived from the total fade.
a Select Enable ULPC.

Configuring the Global Network Parameters
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.

Configuring IP
Routes

Configure the basic parameters of the VSATPlus 3 Terminal that is the
primary reference terminal – Configuring the Primary Reference Terminal
on page 36.
If not connected, connect to the user interface of the terminal that is the
primary reference node – Connecting to the User Interface on page 35.
To configure the IP Routes, click Configure > Route.
Only static routing is supported.
The VSATPlus 3 network centrally manages the IP addresses of all terminals
and distributes the addresses to all terminals.
To configure the IP network:
• Define the IP address of each terminal. This simultaneously defines the
IP subnet on the Ethernet port that is accessible through the configured
terminal.
• Define a default route for each terminal.
• Define IP routes to additional subnets that are within the network.
How you configure a terminal depends on whether or not the default route
of the node is by way of a LAN gateway or is over-the-air.
• LAN Gateway – The LAN gateway is typical for nodes that are collocated
with 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 LAN gateway, set the Default terminal to – (dash). This
setting signifies that the terminal does not have a default route that is
over-the air.
Define the actual default routes separately for each terminal. The first
type of default route is a default route through a gateway that is locally
connected to the LAN port of a terminal. The second type is a default
route over-the-air through another terminal.
In the following example network, Entry 4 indicates that Node 15 has
no Default Terminal value. This means that the default IP Gateway is
on the LAN side, rather than over-the-air.
• Default Terminal (over-the-air) – If you set the Default terminal to a
non-zero value, then the terminal configures a default route over-theair to the specified terminal. To remove a default over-the-air route, set
the Default Terminal to – (dash).
In the following example network, Nodes 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.

Define the route parameters:
For Terminal:
Terminal Number
• Enter the number of the terminal for the local subnet.
IP Address
• Enter the LAN IP address of the terminal.
• The IP address and mask define the IP subnet that is accessible from
the terminal.
Network Mask (CIDR)
• Enter the network mask of the local subnet in CIDR format (0 to 32).
• The Mask defines the subnet address that is routed.
Default Terminal
• The Default Terminal field is similar in concept to the Default Route. To
route packets to the Internet, each terminal has either a Default
Terminal (for routing over-the-air) or an explicit IP Gateway on the
terrestrial Ethernet port.
In the example network:
• Terminals 6 and 10 define Terminal #15 as the Default Terminal.
• Terminal 15 connects to the Internet Service Provider (ISP) on the
terrestrial side, so it does not have a Default Terminal (set to –).
For Route:
Terminal Number
• Enter the number of the terminal for the associated route.
• Entry 5 defines a subnet that is beyond Terminal 6: 172.16.206.1/24.

• If a packet is addressed to another subnet, then it must be forwarded
to an IP Gateway. Typically, an IP Gateway belongs to multiple subnets
and has an IP address in each subnet. In this field, you must enter the
IP address of the gateway node that belongs to the same subnet as the

Configuring IP
Links
6
7
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:
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.
44
PolarSat
VSATPlus 3 Terminal
01-3000-001
Final
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.
8
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 %.
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.
PolarSat
VSATPlus 3 Terminal
45
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.
9
Configuring the
Carriers
The carrier definitions defines the frequency offset for each carrier, in the range
of +/– 20 MHz, starting from carrier 0. Define the frequency offsets of each
carrier as seen at the satellite and, for L-Band terminals, independently of the
transmit and receive spectral inversion settings for each 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.

Final
IF Type
The Intermediate Frequency (IF) is defined by the modem hardware
signature.
• The possible values are 70 MHz or L-Band.
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.
• 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 the 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 64.
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.
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

Final
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.

Select Configure > QoS.
The page displays QoS rules in descending order of processing.
2
You can create, edit, or delete rules. Either:
• In the Action column, click the Edit icon for the rule.
• Double-click a 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.

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.

Final
VSATPlus 3 >
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
