The CDM-425 Advanced Satellite Modem (Figure 1-1) is intended for closed network
applications. It is backwards compatible with the CDM-625 and CDM-625A in VersaFEC modes.
It is also backwards compatible with the CDM-625A in VersaFEC-2 modes.
•
It is compact – 1RU high and 14.0 inches deep – and consumes 43 watts (typical) with
AC supply and Packet Processor, and 40 watts (typical) with DC supply and Packet
Processor.
•
It features front panel Light Emitting Diode (LED) Indicators, a keypad, and a Vacuum
Fluorescent Display (VFD) for local configuration and monitoring and control (M&C). It
also can be fully remote-controlled through its serial remote control or Ethernet-based
HTTP (Web Server), SNMP or Telnet Command Line interfaces.
•
It provides a full range of built-in (i.e., no plug-in cards required) traffic data interface
types, including EIA-530/422, V.35, G.703 E1/T1 types, Quad E1 Drop and Insert, and
10/100 Ethernet.
•
Its IF frequency range simultaneously covers 50-180 MHz and 950-2250 MHz. The
extension to 2250 MHz is to address the needs of future high-throughput satellites (HTS).
