(ISU).
The CRS-500 is compatible for use with the Comtech EF Data CDM-625/625A modems when
equipped with the optional IP Packet Processor, and the Comtech EF Data CDM-750 or CDM-
760 Advanced High Speed Trunking Modems when equipped with either Copper Gigabit Ethernet
(also referred to as GigE), Packet Processor (CDM-760), or Copper E3/T3/STS-1. The CRS-500
is intended for hub applications, and provides fully automatic or manual Traffic Modem protection
of up to 10 Traffic (Prime) Modems with one Redundant (Standby) Modem.
