FLM-2 12-Channel Local Multiplexers
FEATURES
TDM multiplexer with built-in modem SPECIFICATIONS The FLM-1 and FLM-2 time division multiplexers combine up to 12 terminals onto a single cable. A built-in modem drives the high speed multiplexed data over one of two cable options on the main channel: - 4-wire, for transmitting over two twisted pairs - dual fibre optic cables The FLMs multiplex 12 independent signals. They can be used to concentrate six channels of data and one control signal for each, or 12 channels of data only. In the FLM-2, three of the 12 subchannels can operate in synchronous mode using the device's clock. Each subchannel's operating bit rate is selectable, operating independently from the other subchannels. The transmit clock can be: - sourced internally - sourced externally - slaved to the receive clock Local and remote digital loopback capabilities, provided through front panel switches and LEDs, enable diagnostic tests. Indicators are located on the front panel for Power, Test, Local Sync Loss and Remote Sync Loss. The multiplexers have 12 RS-232/V.24 interfaces available via six D-type 25-pin female connectors or 12 RJ-45 connectors. The line connector of the 4-wire version can be terminal block or RJ-45 connector. The FLM-1 and FLM-2 are standalone units, with optional mounting hardware for a 19" rack.
