Overview

The FRM220-E1/Data is a single port G.703/704 Fractional E1 DSU/CSU card for the FRM220 Series Media Converter chassis. This converter supports Unframed, PCM31, PCM31+CRC4, PCM30, and PCM30+CRC4 framing modes.

 

Flexible clocking.

The clock source may be selected internally, recovered from received E1 signal, externally from the Data port or transparent. The data port interface utilises a single hi-density 26pin connector. Cables are provided for RS-530/449,X.21,V.35 or RS-232. The unit can recognise the cable type attached and automatically self-configure the interface.Choosing from one of two model types, the E1 connection is either unbalanced 75ohm with two BNC connectors or balanced 120ohm with one RJ-45connector.

 

Fully manageable

When the FRM220-E1/Data card is placed in the FRM220 rack with an NMC management card, the administrator can view the card's status, type, version, E1 link status and alarms. The card can be configured to enable or disable the port, reset the card, set clocking, frame mode, interface type and provide analog or digital loopbacks. 

 

Standalone or rackmount

A unique feature of the FRM220-E1/Data is the use of a common card design which may either be inserted in the FRM220-CH01 single slot chassis as a stand-alone modem or as a card when placed in the FRM220-CH20 managed rack.
