Introduction
The FRM220-E1/Data is a single port G.703/704 Fractional E1 DSU/CSU card for the FRM220/220ASeries Platform Media Converter Rack. The converter supports Unframed, PCM31, PCM31+CRC4, PCM30, and PCM30+CRC4 framing modes. The clock source may be selected internally, recovered from received E1signal, externally from the Data port or transparent. The Data port interface utilizes a single Hi-Density 26pin connector. Cable solutions are provided for RS-530/449, X.21, V.35 and RS-232. The unitcan recognize the cable type attached and automatically self-configure the interface circuits. Choosing from one of two model types, the E1 connection is either unbalanced 75 ohm with two BNCconnectors or balanced 120 ohm with one RJ-45 connector. When the FRM220-E1/Data card is placed in the FRM220 rack with SNMP management, the management can view the converter card's status, type, version, E1link status and alarms. The card can be configured to enable or disable the card, reset the card, set clocking, frame mode, interface type and provide analog or digital diagnostic loopbacks. A uniquefeature of the FRM220E1/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-CH20In-band managed rack.
