The LMX-4A is an efficient, low-cost, bit-interleaved, four-port, asynchronous Time Division Multiplexer (TDM),
complete with an integral four-wire limited distance line driver(modem). The LMX-4A allows for interconnection of up to four local clustered terminals operating at asynchronous data rates, from 0-64 Kbps. The internal line driver provides limited distance communications over
private, in-house four-wire, point-to-point cable systems, for a range of up to 3300 feet.
Dual fiber optic availability using the optional fiber interface enables a range of up to 10,000 feet (3 km). The LMX-4A is an ideal cost alternative to more expensive statistical multiplexers and leased-line modems.
Ideal applications are those used within a building, in a campus setting, or factory environment using either twisted copper pairs or fiber optic cable.
