Overview
System Overview
The typical IP over-satellite system consists of a network hub with a single, very high-speed uplink broadcasting to
numerous remote stations, each of which includes an IPSat GW1000 terminal.
The IPSat GW1000 Terminal is part of a satellite-based IP network that allows remote sites high-speed
communications access to and from LAN/WAN links. The IPSat GW1000 provides full two-way connectivity to the
hub over a satellite channel and to a local Ethernet network through a standard 10/100Base-T interface. The hub
receives inbound SCPC satellite carriers from IPSat GW1000 remote terminals through a Multiple Receive Terminal
(MRT), offering up to 12 demodulators in only nine rack units of space.
The hub system is scalable from 1 to 72 Mbps outbound and can support virtually any number of satellite return
channels. Any combination of Internet protocol data streams, both TCP and UDP, unicast and multicast, may be
carried between the hub and remote stations. Radyne ComStream can also integrate additional networking
equipment and applications based on your system requirements.
Basic Network Topology Diagram
Hub Equipment
While the networking equipment used in the hub will vary greatly with the particular application of the network, the
basic core of the system remains the same and includes the following:
• Internet Protocol Encapsulator (IP Encapsulator)
• Satellite Modulator, DM-240
• Multiple Receiver Terminal (MRT)
• Optional Equipment
Hub Network Functional Block Diagram
101-0945-401 Rev A 08/2004
Internet Protocol Encapsulator (IPE)
The IPE receives data from the hub IP network and encapsulates the data into a MPEG transport stream according to
DVB data broadcast specification EN 301 192.
Satellite Modulator DM-240
The DM-240 is ComStream's standard DVB-compliant satellite modulator. Connecting to the IPE, the input
interfaces include DVB SPI, ASI, M2P, and RS-422. The modulator accepts the input MPEG transport stream and
provides scrambling, FEC encoding, and modulation of the satellite carrier channel in accordance with DVB
specification EN 300 421.
Multiple Receiver Terminal (MRT)
The MRT is a 9 rack-unit chassis housing redundant, hot-swappable AC power supplies, L-band amplifiers and
distribution, and up to 12 SCPC demodulators.
The chassis includes integrated cooling fans and front panel LEDs showing status of all installed demodulators. The
demodulator cards are hot swappable and operate between 19.2 kbps to 8.448 Mbps, meeting the same performance
specifications as ComStream’s standard DBR2000 receiver. Each demodulator is connected to a Cisco router, which
provides a standard Ethernet interface to the hub Ethernet network for return channel traffic from remote stations.
Optional Equipment
Based on the system application, a network may require additional equipment including:
• MPEG video and audio encoders
• TCP optimization hardware
• Quality of service (QoS) or traffic-shaping hardware
• Basic network equipment
• Application servers

IPSat GW1000 Overview
The IPSat GW1000 Terminal is an integrated two-way SCPC satellite modem with combined IP router/bridge
functionality designed specifically to carry high-speed broadband internet traffic.
IPSat GW1000 Remote System Block Diagram
The IPSat GW1000 Terminal is a two rack-unit chassis including a DVB-compliant demodulator, MPEG transport
demux, IP stack processor, and Ethernet controller functions. Innovative design of the receive path allows use of up
to the full satellite channel bandwidth to output to the Ethernet port.
IP data passed to the IPSat GW1000 Ethernet port is accepted and processed based on internal static routing tables,
framed in HDLC packets, and passed to the satellite modulator. The modulator scrambles, FEC encodes, and
modulates the data on an L-band IF carrier for transmission to the satellite. Up to 64 static routes may be defined in
the IPSat GW1000.
Connecting multiple client computers through an Ethernet Hub may cause data collisions and subsequent loss of
data. To resolve this potential issue, Radyne ComStream strongly recommends the use of an Ethernet Switch on the
IPSat GW1000 Ethernet interface.
Installation
This chapter provides step-by-step procedures for installing and cabling the IPSat GW1000 and a description of all
IPSat GW1000 rear panel connections and required cables.
Do not remove the IPSat GW1000 top cover! The IPSat GW1000 is powered by an exposed, switching AC power
supply which presents an electric shock hazard when the top cover is removed. Personal injury or damage to the
equipment can occur when the top cover is removed. None of the procedures in this manual require the removal of
the IPSat GW1000 top cover.
Before beginning your installation, read the Safety Precautions as they contain important safety information and

IP Address: Used to identify the IPSat GW1000 on the network and is usually defined by your service provider
Subnet Mask: Used by the IPSat GW1000 in conjunction with its IP address to make forwarding decisions and is usually defined by your service provider.
Default Gateway: Used in situations where one or more routers exist on the IPSat GW1000’s subnet accessible
through the Ethernet interface. When a packet is received from the DVB channel and the IPSat GW1000 determines
that the packet contains a destination IP address that is not on its own subnet, the IPSat GW1000 forwards the packet
to a gateway. The gateway is chosen by searching the static routes that have been defined; if no static route exists to
handle the destination network, the packet is forwarded to the default gateway. Note: The default gateway (and static
route) configuration only applies to forwarding decisions made on packets received by the DVB port (demodulator
or receive port), not packets received by the Ethernet port. Packet received by the Ethernet port that contains an
unknown destination network will be forwarded out the HDLC port (modulator or transmit port).
MPEG PID 1: When a PID (Program Identifier) value is entered, the IPSat GW1000 will accept and process all
traffic received by the DVB port (demodulator or receive port) that contains the PID value. At least one PID must be
entered to receive DVB traffic and is usually defined by your service provider.
Subscribed Rx BW: Enter the amount of bandwidth that the IPSat GW1000 is subscribed to receive from the
service provider. The IPSat GW1000 uses this parameter to accurately reflect the network activity on the front panel
display.
RC-Rx coding rate: Sets the type and rate of the FEC (Forward Error Correction) decoding performed by the
demodulator. Defined by service provider. Default is Vit 2/3.
RD-Rx Data Rate: Sets the data rate in bps (bits per second) that the demodulator receives at and is usually defined
by your service provider. The Rx Symbol Rate is automatically determined by the Rx Coding Rate and the Rx Data
Rate.
RS-Rx Frequency: Sets the L-band frequency in Hz (hertz) that the demodulator receives at and is usually defined
by your service provider.
TC-TX Coding Rate: Sets the type and rate of the FEC (Forward Error Correction) coding performed by the
modulator. Defined by service provider. Default is Vit 1/2. Note: When the service provider is using Radyne
ComStream’s MRT (Multiple Receiver Terminal), the TX Coding Rate must use the DVB symbol-mapped Viterbi
types (DVB 1/2, DVB 3/4, DVB 7/8) or the sequential types.
TD-TX Data Rate: Sets the data rate in bps (bits per second) that the modulator transmits at and is usually defined
by your service provider. The TX Symbol Rate is automatically determined by the TX Coding Rate and the TX Data
Rate.
TS-TX Frequency: Sets the L-band frequency in Hz (hertz) that the modulator transmits at and is usually defined
by your service provider.
TP-TX Power Level: Determines the power level in dBm (decibel-meter) that the modulator transmits at. Default is
0.0dbm.
EM-Modulator: Enables or disables the modulator. It performs the same function as pressing TX Enable on the
front panel. Default is disabled.
HP-10 MHz Reference: Enables or disables 10 MHz BUC (Block UpConverter) reference frequency. Default is
disabled.
MIV-24 Volt Output: Selects the source for the power to the BUC (Block UpConverter). Choices are disabled,
enabled internal and enabled external. Default is disabled. Note: Enabled internal has a maximum of 24vdc at 3
AMPS.
AE-Modulator Auto Enable: Used to automatically return the modulator, 10 MHz and 24vdc to previous state
upon power-up or reset when set to Auto; otherwise, when set to manual, the modulator must be manually enabled
upon power-up or reset. Default is Manual.
PC-Pure Carrier: Enables or disables the transmission of an unmodulated carrier (continuous wave) out of the
modulator. The pure carrier signal is used for diagnostic and installation procedures. Default is disabled.
Once all of the parameters have been configured, press the Esc key. A reset may be required for some of the settings
to take effect. If this is the case, the IPSat GW1000 will reset itself after displaying a user prompt.
Refer to the Console chapter for more information about configuration and monitoring tasks and utilities that are

[1] IP Address: Used to identify the
IPSat GW1000 on the network and is usually
defined by your service provider.
[2]

make forwarding decisions and is usually
defined by your service provider.
Default Gateway: Used in situations
[3]
where one or more routers exist on the IPSat
GW1000's subnet accessible through the
Ethernet interface. When a packet is received
from the DVB channel and the IPSat
GW1000 determines that the packet contains
a destination IP address that is not on its own
subnet, the IPSat GW1000 forwards the
packet to a gateway. The gateway is chosen
by searching the static routes that have been
defined; if no static route exists to handle the
destination network, the packet is forwarded
to the default gateway. Note: The default
gateway (and static route) configuration only
applies to forwarding decisions made on
packets received by the DVB port
(demodulator or receive port), not packets
received by the Ethernet port. Packets
received by the Ethernet port that contain an
unknown destination network will be
forwarded out the HDLC port (modulator or
transmit port).

[1] MAC Address: The Media Access
Control address (physical address) of the
Ethernet port. While it is possible to change
the address, this is not recommended since
there is no guarantee that it will be unique.
The MAC address is also used by your
service provider to identify your IPSat
GW1000.
[2] Port Setting: In Auto-negotiation
Mode, the IPSat GW1000's Ethernet port will
automatically negotiate its speed and duplex
with the Ethernet port of the device the IPSat
GW1000 is plugged into. In Manual Mode,
the console will allow the user to specify the
port speed and duplex.
Note 1: When connecting two Ethernet
devices together, both devices should be set
to use the same port settings. For example, if
the IPSat GW1000 is set to use autonegotiation, the Ethernet device it is
connected to should also use autonegotiation. If this advice is not heeded, your
network performance could be reduced due to
excessive collisions.
Note 2: The Port Speed and Port Duplex
Mode options only appear when Manual
Mode is selected for the Ethernet port.
[3] Port Speed: The manually configured
speed of the Ethernet port.
[4] Port Duplex Mode: The manually
configured duplex mode of the Ethernet port.

Routes
When the IPSat GW1000 must forward
traffic to multiple networks that are
accessible through different routers on the
IPSat GW1000's subnet, static routes must be
used. To add a static route, press "a". You
will be prompted to enter the following:
Destination: The destination network IP
address.
Mask: The destination network subnet mask.
Gateway: The IP address of the gateway
(router) that will forward the packet to its
final destination or the next hop.
Port: The port that the incoming packet will
be forwarded out. This should always be the
Ethernet port unless a Multicast static route is
entered, in which case, the HDLC port should
be chosen.
Note: The default gateway and static route
configuration only apply to forwarding
decisions made on packets received by the
DVB port (demodulator or receive port), not
packets received by the Ethernet port.
Packets received by the Ethernet port that
contain an unknown destination network will
be forwarded out the HDLC port (modulator
or transmit port).
Configuration Example:
Consider the network diagram below for the
following discussion. Assume that Router A
can forward packets to ten different networks,
Router B can forward packets to network
192.168.34.240 with subnet mask
255.255.255.248, and Router C can forward
packets to network 192.168.34.232 with
subnet mask 255.255.255.248.
[IPSat GW1000]-------[Switch]--------[Router A]
The easiest way to configure the IPSat
GW1000 for this network is to perform the
following three steps:
1. Configure a default gateway of 10.0.0.30
on the Basic Configuration page. Using the
default gat
gateway in this instance saves the user from
entering ten static routes.
2. Configure a static route as follows:
Destination: 192.168.34.240
Mask: 255.255.255.248
Gateway: 10.0.0.35
Port: Ethernet
3. Configure a static route as follows:
Destination: 192.168.34.232
Mask: 255.255.255.248
Gateway: 10.0.0.40
Port: Ethernet

This value depends on the type of equipment
your service provider is using to process the
IPSat GW1000’s HDLC (transmitted) traffic.
16-bit address mode is used for Cisco
equipment and 0-bit address mode is used for
RAD equipment. Your service provider
should provide you with this setting.
The IP address that is used by your service
provider's NMS (Network Management
System). The NMS allows your service
provider to configure your IPSat GW1000
and gather statistics from your IPSat
GW1000.
[1] MI - TX Spectral Inversion:
Enables or disables transmit spectral
inversion. Default is Disable
[2] TM - TX Modulation Type:
Modulation type can be set to QPSK or
BPSK. This should be provided by your
service provider. Default is QPSK.
[3] TO - TX Offset: A frequency that is
added (or subtracted) to the TX frequency.
Default is 0hz.
[4] ROE - Radio Output Enable: The
amount of time that the IPSat GW1000 will
wait upon power-up or reset to automatically
enable the modulator. The BUC requires a
warm-up period in order for accurate
transmission characteristics. Default is 180
seconds.
[5] TR - TX Symbol Rate: The symbol
rate at which the modulator transmits at.
19
01-0945-401 Rev. A 08/2004
It can be entered in sps (symbols per second).
When changing the symbol rate, the data rate
in the Basic Configuration will also change.
Symbol rate is related to data rate using the
following equation:
Symbol Rate = (Data Rate / (Code Rate x
Modulation Index))
For example, the symbol rate of a 2 Mbps,
Viterbi-DVB 3/4, QPSK transmission is
Symbol Rate = (2000000 / ((3/4) x 2)) =
1333333 sps
[6] DM - Differential Encoding on modulator: Enables or disables differential
encoding. Used to protect from the possibility
of phase ambiguity errors. Default is on.
[7] SM - Scrambling Type on modulator: selects type of scrambling
algorithm applied to transmit data stream.
Default is ComStream.
[8] PD - Power Detect: Enables or
disables optional power detector. Default is
disabled.
[9] MFS - Modulator Filter Select:

[1] EBT - Eb/No Threshold: When the
Eb/No falls below the Eb/No threshold, the
IPSat GW1000 will report a fault. Default is
0db.
[2] AO - Acquisition Offset: When the
demodulator begins its acquisition process, it
will begin its search at the Rx frequency plus
or minus the acquisition offset. For example,
if the Rx Frequency is 1200000000 Hz and
the acquisition offset is 1000 Hz, the
demodulator will begin its acquisition at
1200001000 Hz. Default is 0hz.
[3] DD - Differential Decoding: Enables
or disables differential decoding. Used to
protect from the possibility of phase
ambiguity errors. Default is on.
[4] RM - Rx Modulation Type:
Modulation type can be set to QPSK or
BPSK. This should be provided by your
service provider. Default is QPSK.
[5] RR - Rx Symbol Rate: The symbol
rate at which the demodulator receives at. It
can be entered in sps (symbols per second).
When changing the symbol rate, the data rate
in the Basic Configuration will also change.
Symbol rate is related to data rate using the
following equation:
Symbol Rate = (Data Rate / (Code Rate x
Modulation Index)) x Reed-Solomon
Overhead
For example, the symbol rate of a 70 Mbps,
Viterbi 7/8, QPSK transmission is
Symbol Rate = (70000000 / ((7/8) x 2)) x
(204/188) = 43404256 sps
[6] SD - Descrambling Type: enables or
disables DVB descrambling algorithm
applied to receive data stream. Default is
DVB descrambling.
[7] DFS - Demod Filter Select: Selects

Before the IPSat GW1000 can forward a
packet, it must decide which port the packet
should be forwarded out of based on the
source and destination IP addresses contained

Before the IPSat GW1000 can send data to a
host on its Ethernet subnet, it must know the
host's physical address or MAC (Media
Access Control) address. The ARP (Address
Resolution Protocol) table contains a
MAC address and IP address mappings.
Entries
will be removed from the table
according to the ARP Table Timeout value. Demodulator Status: Reports whether the
demodulator is synchronized or not
synchronized to a carrier signal.
Modulator Status: Reports whether the
modulator is enabled or disabled.
AGC value: The AGC (Automatic Gain
Control) of the demodulator is a gauge of
how powerful the received signal is. As the
signal strength increases, so does the AGC
value.
Eb/No: The Eb/No value is the energyper-bit with respect to noise (or signal-tonoise ratio) of the signal received by the
demodulator.
Receive Offset: The frequency difference
between the signal acquired by the
demodulator and the configured Rx
frequency.
Displays the number of packets received on
each configured PID in the DVB stream.
[DVB] Received Packets: Number of
packets received on the DVB port.
[DVB] Dropped Packets: Number of
packets received at the DVB port that could
not be forwarded due to an unresolvable
destination IP address or some other error
condition.
[DVB] Local Packets: Number of packets
received on the DVB port that are destined
for the IPSat GW1000.
[Ethernet] Transmitted Packets:
Number of packets that are transmitted out of
the Ethernet port.
[Ethernet] Received Packets: Number of
packets that are received by the Ethernet port.
[Ethernet] Receive Errors: Number of
errors that occur on received packets on the
Ethernet port. For example, if the IPSat
GW1000 receives a frame that is too short
due to an Ethernet collision, an error will be
logged. Another example would be when the
IPSat GW1000 receives traffic at a faster rate
than it can transmit.

When new features are added or "bugs" are
fixed, a firmware upgrade is required. The
firmware can be downloaded to the IPSat
GW1000 using the console interface or your
provider may choose to download it through
the DVB stream. For the fastest console
download, the console port speed should be
set to 115200 bps and 1K X-MODEM should
be used as the transfer protocol. Note: While
a firmware upgrade is being downloaded, the
IPSat GW1000 will not forward any network
traffic.

Appendix B
Cable Specifications
This appendix provides installation procedures and defines the required performance parameters for the following
cables and connectors:
• IFL TX and Rx cables
• Y-cable
• Optional Power Detector Cable
• IFL F- and N- connectors
IPSat GW1000 Cabling
IFL Cables
IFL cables must conform to the specifications provided in this manual to ensure that ComStream equipment operates
properly.
Quad-shielded coax must be used for IFL cables. Without quad shielding, the system may be subject to outside RF
interference, which can degrade performance.
IFL cables must be properly installed for the system to operate at the specified performance levels. Radyne
ComStream strongly recommends purchasing the following IPSat GW1000 IFL cables from the following vendors:
• LMR-400 quad-shielded coaxial cable, Times Microwave Communications, 800-867-2629
• RG-11 quad-shielded coaxial cable, type 2282, Times Fiber Communications, 800-677-2288
It is assumed that the TX and Rx IFL cables are the same length. A record of the length of these cables should be
kept for reference. Radyne ComStream can provide complete IFL Kits including all required connectors and cables
pre-wired...
3101-0945-401 Rev A 08/2004
IFL F- and N Connectors
Radyne ComStream supplies the necessary F- and N-connectors for use with the IPSat GW1000 IFL coax cables.
These connectors are designed for the recommended Times Microwave LMR-400 and Times Fiber RG-11 coaxial
cable. If another IFL coaxial cable is used, different F and N-connectors will be required and must be matched to the
coaxial cable selected.
IFL F-Connector
The F-connectors supplied with the IPSat GW1000 are designed to be used with the recommended Times Fiber RG11 coaxial cable. One F-connector must be installed on both the indoor and outdoor ends of the Rx coaxial cable. A
crimping tool must be used to securely fasten the F-connector collar. Although this crimping tool is available from
different vendors, ComStream recommends the following vendor for additional F-connectors or crimping tools:
• CABLE Prep, 203-526-4337
• Crimp tool part number HCT-211
For up-to-date information on vendors, contact your Radyne ComStream representative.
RG-11 Cable Assembly with F-Connector
To prepare the RG-11 cable and attach an F-connector, follow these steps.
1 Expose 5/16 inch (7.9 mm) of the center conductor. Ensure that the center conductor is not scored.
2 Remove 1/4 inch (6.4 mm) of jacket. Ensure that the braid is not cut. Fold exposed braid back over the
cable jacket.
1 Remove first foil. Ensure that the braid is not cut. Fold the second braid back over the cable jacket.
1 Guide the center conductor into the connector. Push the connector onto the cable until a reasonable stop is
felt.
2 Crimp the connector using the recommended crimping tool (.475 inch [12.1 mm] hexagon tool.)
IFL N-Connector
The N-connectors supplied with the IPSat GW1000 are designed for the recommended Times Microwave Quadshielded LMR-400 coaxial cable. One N-connector must be installed at both the indoor and outdoor ends of the TX
coaxial cable. By using the quad-shielded LMR-400 cable from Times Microwave, cable runs of up to 100 m (328
ft.) can be used for data rates above 19.2 kbps. For lower data rates, the maximum cable lengths are shown in the
following table.
Data Rate (kbps) Maximum Cable Length (m)
9.6 86
19.2 100
The maximum length assumes a receive Eb/N0 of 5 dB. With higher Eb/N0 values, maximum cable runs can be
increased to a maximum of 100 m. This cable attenuates the received signals by 6 dB per 30.5 m (100 ft.). For
longer cable runs, the receive signal E
caused by the additional cable length. For example, increase the far end transmit power by 6 dB for each additional
30.5 m of IFL coax cable length.
must be increased by an amount equal to the increased signal attenuation
b/N0
3201-0945-401 Rev A 08/2004
Cable Loss
For all data rates, the degradation of system NF due to the IFL coaxial cable is negligible for cable lengths up to 100
m (328 ft.).
LMR-400 Cable Assembly with N-Connector
To prepare the LMR-400 cable and attach an N-connector, follow these steps.
1 Flush cut end of cable using a fine saw blade. Cut cable so that the end remains round and the face of the
cable is perpendicular to its length. Slide on shrink boot, clamp nut, washer, and gasket.
2 Expose the 0.240 inches of the conductor. Cut through the cable jacket, braids, and dielectric core. Do not
nick the cable conductor.
3 Expose 0.500 inches of the outer braid. Do not to nick the braids when removing the cable jacket.
4 Slide on the ferrule. Ensure that all braids come up through the ferrule
5 Flare out the braids and fold them back onto the ferrule. Trim braids to shoulder. Trim core back to 0.030
inches maximum. Trim the conductor back to 0.230 inches.

01-0945-401 Rev. A 08/2004
6 Install the contact. Solder on the contact using 60/40 solder. Feed solder through solder hole while
heating the contact.
7 Install the connector body onto the cable. Check for proper pin height. Apply Locktite 242 to the clamp nut
threads. Thread the clamp nut into the connector body. Torque to 50 in-lbs. Check pin height.
8 Install strain relief boot. Position the boot onto the connector body. Apply hot air until boot is smoothly
seated onto both the cable and connector. Use only an adhesive lined shrink boot.

Appendix C
Outdoor Unit Recommendations
For TX IFL cable lengths less than those listed in the following table, an in-line attenuator should be inserted into
the cable. ComStream recommends the use of a Radyne ComStream attenuator, part number 17-0107-101. The
attenuator ensures a minimum dynamic range of 15 dB in the output power.
The minimum cable length should be used as a guide by the system integrators and installers as an approximation
only.
The maximum cable length is 100 meters in all installations.
Radyne ComStream strongly recommends the use of Times Microwave LMR-400 TX IFL cable and Times Fiber
RG11 quad-shielded Rx cable. For information on ordering LMR-400 or RG-11 cable, refer to the appendix on
cable specifications.
The following table provides the recommended Outdoor Unit:
