DESCRIPTION

•

FLM-1 is a time division

multiplexer enabling up to twelve

asynchronous terminals to be

multiplexed onto a single cable for

point-to-point applications. Up to

four FLM-1 units can also be

installed in a ring application

involving clusters of terminals at

various locations. A built-in

modem in the FLM-1 drives the

high speed multiplexed data over

fiber-optic or twisted-pair cable.

•

FLM-1 can be user-selected to

operate with twelve channels, or

with six channels for improved

performance.

•

When set to six channels, each

channel can be used to transmit

full duplex data end-to-end.

When set to twelve channels,

each channel can be used for

either data or control signal

transmission. This allows six

channels, for example, to be used

for transmitting full duplex data,

and six other to be used for

transmitting control signals

end-to-end. Alternatively, all

twelve channels can be used to

transmit full duplex data

end-to-end.

•

Two channel interfaces options

are available (see Ordering):

six 25-pin D-type, female

connectors, which can be

expanded to support twelve

channels by using channel

doubler cables, or

twelve RJ-45 connectors, each

supporting a single channel.

•

FLM-1 offers two cable options for

the main link interface:

4-wire for transmitting over two

twisted copper pairs, or

dual fiber for transmitting over

duplex fiber-optic cable.

•

The main link copper interface is

available with either a 5-screw

terminal block, or an RJ-45

connector. The optical interface is

available with a variety of

connectors and wavelengths (see

Ordering).

•

FLM-1 is available as a standalone

desktop unit. Special hardware for

mounting in a 19" rack is available

(see Ordering).
