A.6 FRM220-Data (to be announced)
The FRM-DATA is a high-performance serial over fiber media converter. These converters fully support Nx64
data transmissions up to 2.048Mbps and completely handle flow control and clocking signals in synchronous
applications over fiber media. Additionally, the converters support low speed asynchronous connections as well.
There are five models of FRM-DATA media converters, V.35, RS-232, RS-530, X.21, and RS-449 which are based
upon three basic hardware types, V.35, RS-232, and RS-530. The RS-530 hardware is also the source for the X.21 and
RS-449 models. All models require adapter cables to adapt the unit's HDB26 interface connectors.
There are two 8 position DIP switches located on the side of the FRM-DATA to configure the units when used
standalone. When the FRM-DATA is placed in the FRM220 with SNMP, the settings are controlled by the chassis
management system and any DIP settings are ignored. Additionally, when placed in the managed rack, the
remotely linked FRM-DATA unit is also controlled and configured through the in-band management system.
