Introduction
The FRM220A-Eoe1 is a single port G.703/704 Fractional E1 DSU/CSU
card with built-in HDLC Bridge for the FRM220/220A Series Platform Media
Converter Rack. The converter supports Unframed, PCM31, and PCM30
framing modes. The clock source may be selected internally or recovered
from received E1 signal. The Ethernet port utilizes a single RJ-45
connector. One single model supports either unbalanced 75 ohm with two
BNC connectors or balanced 120 ohm with one RJ-45 connector. When the
FRM220A-Eoe1 card is placed in the FRM220 rack with SNMP
management, the management can view the converter card's status, type,
version, Ethernet link status and alarms. The card can be configured to
enable or disable the port, reset the card, set clocking, frame mode and
provide analog diagnostic loopbacks. A unique feature of the FRM220A-
Eoe1 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 In-band managed rack.
