Introduction
The FRM220A-Eoe1/G is a single E1 Bridge for the FRM220/220A Series
Platform Media Converter Rack. The converter supports Ethernet
transmission over Framed/Unframed E1 using GFP-F (Generic Framing
Procedure-Framed). The clock source may be selected internally or
recovered from any one of the received E1 signals. The Ethernet port
utilizes a single RJ-45 connector or SFP for optical fiber, depending on
model. One single model supports either unbalanced 75 ohm via BNC
connectors or balanced 120 ohm via RJ-45. When the FRM220A-Eoe1/G
card is placed in the FRM220A rack with GSW/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, Ethernet mode and provide E1 analog
diagnostic loopbacks. A unique feature of the FRM220A-Eoe1/G is the use
of a common card design which may either be inserted in an appropriate
single or dual slot chassis as a stand-alone modem or as a card when
placed in the FRM220A-CH20 In-band managed rack.
