Comtech CRS-530 Redundancy Controller

Description

The Comtech CRS-530 Control Switch Unit is the redundancy controller of the CRS-500 Redundancy System and consumes only 1RU of rack space. The Comtech CRS-530 Control Switch Unit contains field-replaceable modules such as the CRS-530 controller and dual, hot-swappable Power Supply Units (PSUs). The configuration of each traffic modem is stored in the CRS-530 controller. This information is used to program the redundant modem if a traffic modem fails.

The Comtech CRS-500 1:N Modem Redundancy System is the next generation 1:N Modem Redundancy System. Intended for hub applications, it provides automatic or manual protection for up to 10 Traffic (or prime) modems with one redundant (or standby) modem. The Comtech CRS-500 1:N Modem Redundancy System supports the CDM-625/625A, CDM-760 and CDM-750 modems for select interfaces. The CDM-625/625A is supported when using the 10/100 Packet Processor mode. The CDM-750/760 is supported when using the ASI, G.703, Gig-E native interface or Gig-E Packet Processor interface (packet processor and ASI only available on the CDM-760).

The Comtech CRS-500 1:N Modem Redundancy System consists of the following components:

• Comtech CRS-530 M&C Controller
• Cometch CRS-280 IF Switch
• Comtech CRS-280L L Band Switch
• Comtech Data Switch Unit (DSU)
