CDM-570/L & CDM-570/L-IP Satellite Modems

Satellite Modems

Overview

The CDM-570 and the CDM-570L are Comtech EF Data’s entry-level satellite modems that

provide industry leading performance and flexibility in a 1 RU package at a very competitive

price. Designed to address the market for low-cost terminals, the modems are available with

70/140 MHz or L-Band IF and EIA-530/-422, V.35, EIA-232 and G.703 data interfaces. An

optional Internet Protocol (IP) Module with 10/100Base-T Ethernet port is available for IP-

centric applications.

• Redundancy options

• CDM-570 & CDM-570-IP: FSK communications to CSAT-5060 or KST-2000A

• CDM-570L & CDM-570L-IP: 10 MHz reference for BUC, FSK communications and optional BUC power supply

• CDM-570L & CDM-570L-IP: 10 MHz reference and power supply for LNB

• Optional, integrated IP Module with 10/100Base-T Ethernet port (CDM-570-IP and CDM-570L-IP)

 Static IP routing for unicast and multicast

 Header and payload compression for maximum efficiency

 IGMP v1 and v2

 VLAN capability with 802.1Q compliant QoS

 Vipersat Management System (VMS) integration

Turbo Product Coding

The optional Turbo Product Codec delivers significant performance improvement when compared to Viterbi with concatenated Reed-

Solomon. It offers increased coding gain, lower decoding delay, and significant bandwidth savings compared to traditional FEC.

EDMAC & AUPC Operation

The CDM-570/L-IP has the ability to monitor and control the distant end of a point-to-point satellite link using EDMAC or EDMAC2. User

data is framed and bits are added to pass control, status, and AUPC information. This is transparent to the user.

Management

The modems support SNMP, web-based and command line interfaces for management. The modems can also be configured and

monitored from the front panel, or through the remote M&C port (for non-IP mode of operation). Ten complete RF configurations may

be stored in the modem. An event log stores alarm and status information in non-volatile RAM, while the link statistics log stores link

performance (Eb/No and AUPC performance) for monitoring and reporting purposes.
