Chapter 1 Introduction
1.7.10 FRM220-Data In-band managed V.35, X.21, RS-530/449/232 Fiber Modem
The FRM220-DATA is a fiber modem for high-speed (up to 8.192Mbps) synchronous or low speed
synchronous and asynchronous data transmissions (V.35, RS-232, RS-530, X.21 or RS-449) over fiber optical
media. When the FRM220-DATA card is placed in the FRM220 rack with SNMP management, in-band
management allows viewing the card and remote modem's status, type, version, fiber link status, data link status
and alarms. Both card and remote can be configured to enable or disable the port, reset the port, set the data rate,
modify the clock mode, and initiate local or far end loop back tests. The FRM220-Data Fiber Modem may also be
paired with the FRM220-E1/T1 for Nx64K transmissions.
