Product Description
Introduction
The Vipersat CDD-56X Satellite Network Demodulator Router is ideal for
operators wishing to supply mesh connectivity between sites, while keeping
network infrastructure costs down. The CDD-564 and CDD-564L provide four
separate demodulators (the CDD-562L provides two) and an integrated router in
a compact, cost-effective 1RU package.
The CDD-56X simplifies Hub site installations by reducing rack space and cost
with 2/4 independent demodulators in a single chassis. A bank of CDD-56X
demodulators is ideal for a star network consisting of a single outbound carrier
at the Hub with multiple carriers returned from the remote sites.
The CDD-56X can be used at Hub sites where multiple burst controllers are
needed. Demodulator roles are defined via software, configurable either as a
burst controller in STDMA (Selective Time Division Multiple Access) mode, or
as dedicated SCPC (Single Channel per Carrier) inbounds from remote terminals.
At Remote sites, the CDD-56X supports mesh connectivity between multiple
sites. Operating in mesh topology with links directly between sites eliminates
double-hops through the Hub, conserving bandwidth and reducing latency.

• 50–90 MHz or 100–180 MHz IF Range, each Demodulator (CDD-564)
950–1950 MHz IF Range, each Demodulator (CDD-562L/564L)
• QPSK, 8-PSK, and 16-QAM Operation
• Data Rate Range from 16 kbps up to 9.98 Mbps, depending on modulation
and FEC used (with FAST feature upgrade)

Network and Bandwidth Management
A Vipersat-powered network solution integrates this advanced demodulator/
router with the powerful network management tool, the Vipersat Management
System (VMS). The VMS provides for traditional monitor and control of the
CDM-570/570L modems and the CDD-56X demodulators, but more than just
an M&C package, the VMS offers unique bandwidth management that is ideal
for IP-switched networks. Short data transfers are typically executed using a
shared Selective Time Division Multiple Access (STDMA) channel, and when
large amounts of data transfer, voice, and/or video communications are needed,
these units can be automatically switched to a dedicated SCPC channel.
Dynamic SCPC (dSCPC)
The VMS provides for dynamic bandwidth allocation while in SCPC mode,
automatically altering the bandwidth based on traffic conditions. This effectively enables the network to better handle connection-oriented applications and
reduce network congestion, jitter, and latency.
In a typical Vipersat application used in conjunction with CDM-570/570L
modems, the CDD-56X demodulators are drawn from a pool for assignment to a
connection-oriented link.
Traffic inbounds from remotes can be switched manually or automatically,
application or load triggered, or scheduled, from shared STDMA (burst) mode
to a dedicated SCPC connection. The VMS automatically assigns a free demodulator at the Hub to a desired remote inbound, completely eliminating manual
intervention. At remote sites, the CDD-56X simplifies Single Hop On Demand
(SHOD) applications with direct remote-to-remote connections that do away
with double-hops. Once the session is completed, the remote is automatically
reverted back to its home state.
The result is an economical and flexible network with bandwidth shared and
directed where it is needed for any mix of IP voice, video, and data traffic.

Product Description MN/22137, rev 1
STDMA
The addition of STDMA capability to a Vipersat network allows multiple terminals to share the same satellite resources that would be dedicated to a single
terminal in an SCPC configuration. This means that more terminals can be
added to the network with minimal additional cost in either satellite bandwidth
or Hub Terminal hardware.
Vipersat STDMA thus provides a low cost solution for medium to large sized
networks with generally moderate bandwidth requirements, while at the same
time providing all the features of the existing Vipersat systems, including the
availability of a switched pool of SCPC channels for occasional high bandwidth
traffic such as video conferences and large file transfers. Each STDMA
upstream channel from the remote terminals to the Hub uses an STDMA frame
operating at an aggregate data rate of from 16 kbps to 9.98 Mbps and can
support up to hundreds of remote terminals with multiple burst channel
inbounds.
Configured as a Hub terminal, the CDD-564/564L provides one demod for
receiving an upstream STDMA channel from the remotes, and three demods for
receiving three SCPC channels.
Single Hop On Demand
The CDD-56X is ideal for mesh applications such as Vipersat's Single Hop On
Demand (SHOD). With the CDD-56X, SHOD (meshed) circuits are easily and
economically established between remotes. SHOD provides significant and
dynamic connectivity between latency connections without suffering the high
costs associated with multiple carriers and/or 1-to-1 multi-receiver links.
Turbo Product Coding
The Comtech Vipersat CDD-56X incorporates a Turbo Product Codec (TPC)
error correction, delivering significant performance improvement when
compared to Viterbi with concatenated Reed-Solomon. TPC simultaneously
offers increased coding gain, lower decoding delay, and significant bandwidth
savings.
Header Decompression
Header compression reduces the required Voice over Internet Protocol (VoIP)
bandwidth by as much as 60%. Example: a G.729 voice codec operating at 8
kbps will occupy 32 kbps once encapsulated into IP framing on a LAN. Using
IP/UDP/RTP Header Compression, the same traffic only needs 10.8 kbps total
WAN satellite bandwidth to cross the link. The CDD-56X demods perform
header decompression prior to passing the data onto the LAN.
1-6 Vipersat CDD-56X Series User Guide
MN/22137, rev 1 Product Description
Payload Decompression
Payload compression condenses the size of data frames and reduces the satellite
bandwidth required to transmit across the link. Configurable on a per route
basis, Payload Compression provides traffic optimization and reduces bandwidth up to 40%. The CDD-56X demods perform payload decompression prior
to passing the data onto the LAN.
Data Decryption
The CDD-56X decrypts 3xDES data that it receives. Data encryption, configurable on a per route basis, is used to prevent unauthorized access to data over the
satellite link.
New in This Release
The following firmware version incorporates a number of additional features
and enhancements.
1.6.11/2.6.11 Release
Dynamic Entry Channel Mode
Dynamic ECM (ECMv2) utilizes a modified slotted Aloha method for Remotes
to establish registration in the network and obtain the means for switching into
dSCPC mode. Rather than sharing an STDMA burst map, as is the method with
STDMA ECM, the Remotes rely on communicating with the Hub channel
controller through the use of a multicast Transmission Announcement Protocol
(TAP) message. This eliminates the restriction in the number of Remotes in an
Entry Channel group that is inherent with the burst map method.

QUICK START CONFIGURATION
Introduction
This chapter describes the minimum configuration of a Vipersat CDD-56X
Series Demodulator Router that is necessary in order for the equipment to function in a Vipersat network.
The Vipersat CDD-56X Demodulator Router stores its configuration in an
ASCII file named the PARAM file. Equipment Configuration is typically
performed through the use of the Command Line Interface (CLI), particularly
the initial configuration. Once the equipment is functioning in the network,
additional configuration can be performed via the VMS.
Refer to Chapter 3, “Using the Command Line Interface (CLI)”, for a detailed
description on the usage of this feature.
This manual covers the configuration specifics of the CDD-56X when used in a
Vipersat network. Refer to the CDD-564L L-band Quad Demodulator Installa-
tion and Operation Manual for general instruction on setting up, installing and
configuring this equipment.
Note: Before attempting to configure a CDD-56X to be used in a Vipersat
network, make certain it has the Vipersat option installed and enabled.
Chapter 2 - Quick Start Configuration 2-1
Initial Configuration MN/22137, rev 1
NOTE
Initial Configuration
Note: Many of the settings required for equipment configuration are based on
the LAN/WAN and Satellite network design, and should be obtained from
the network administrator.
Terminal Connection
These procedures are performed using the CLI from a workstation connected to
the CDD-56X either via a direct connection to the Console port (a console cable
is shipped with each unit), or via a telnet connection to the Traffic 100 port.
Alternatively, HyperTerminal or any of the other connection methods described
in the CDD-564L L-band Quad Demodulator Installation and Operation
Manual may be used.
Make a terminal connection to the target CDD-56X demodulator/router. If
connecting via the Traffic 100 Ethernet port (do not use the M&C port), enter
the IP address of the unit. The factory default IP address for a Vipersat enabled
unit is 192.168.254.2. Configure the terminal for VT-100 emulation mode.
Once a terminal connection has been made, the CDD-56X will respond with a
Login prompt. The factory defaults for accessing the Admin level are:
Login: comtech
Password: comtech
Once the operator has logged in, the Main Menu shown in figure 2-1 is
displayed.
Network Role
The first and most important step prior to configuring the CDD-56X is to define
its network role.
The CDD-56X is a flexible network component able to perform different functions depending on how it is used in a network. The role that is defined for each
CDD-56X will determine what functions are available for each unit to fill its
role. Table 2-1 lists the network roles and the corresponding network functions
for which the CDD-56X can be configured.

Configure the Route Table
Routing in a Vipersat Network
CDD-56X Demodulator Routers operating in Vipersat mode do not use the
small or large network described in the CDD-564L Installation and Operation
Manual. There is no HDLC address in a Vipersat network; instead, the
CDD-56X role designation — Hub or Remote, Expansion unit or not — determines routing rules that prevent multicast loops. This simplifies the configuration of a Vipersat network.
Because satellite networks are often used as extensions for access to services
such as the Internet or the PSTN, they lend themselves quite readily to private
addressing. For example, to provide Internet access to the satellite network, only
the Hub requires a public IP address in order for the entire satellite network that
is controlled by the Hub to have access to the Internet backbone. Utilizing
Network Address Translation (NAT), the administrator can effectively address
the network using a minimum number of static route statements.
Example:
The IP address 172.16.0.0 is the private address network number for class B
networks. If there is a router at the Hub with a connection to the Internet, the
operator can define the local network as a class B. If the operator splits the Class
B in half and points the upper half toward the satellite there will be over 16000
usable addresses at the Hub as well as at the Remotes. For details on IP addressing, refer to Appendix A, "Network Addressing".
Chapter 2 - Quick Start Configuration 2-7
Initial Configuration MN/22137, rev 1
By putting the one route statement “Remotes 172.16.128.0/17 Wan to Sat” in
the TDM Hub modem, and by using the route statement “GW 0.0.0.0/0 Wan to
Sat” at each of the remote modems, the network will successfully route packets.
The remotes can then be sub-netted as class C networks or below. Additional
routers at the remotes can be added for unusually large sites, allowing an additional layer of NAT without requiring any more explicit routing within the
Vipersat Modem/Routers.
Refer to the CDD-564L Installation and Operation Manual for additional information on entering routes.
Creating the Routes
The following procedure outlines the basic route structure that the target
CDD-56X will require for its role in the network. One of the key routes that
must be created is a gateway address for routing the data traffic that is received
by the unit.
1. From the Main Menu shown in figure 2-1, select Route Table by entering
R at the command prompt.
2. From the Configuring the Route Table screen shown in figure 2-7, enter
1 at the command prompt to set the first route that will define the default
gateway.
In a Hub configuration, the default gateway will typically point to a router
on the same LAN as the CDD-56X Hub unit.
In a Remote configuration, the default route will typically point to the
satellite modem used for communications back to the Hub.
3. When prompted, enter the Route Name (GW), the IP Address, the
Number of Bits in the subnet mask, the Route Interface (Ethernet or Sat-
ellite), and the Next Hop address. The system administrator can supply
this information, if necessary.
In a Hub role, for example, enter the name of the route (e.g., GW), enter
0.0.0.0 for the destination IP address and 0 for the mask, enter E for
Ethernet interface, then enter the IP address of the appropriate router or
modem for the next hop.
