EDWARDS EST 3-MODCOM MODEM/COMMUNICATOR

The Modem Communicator is a two-way local rail module that
performs a variety of off-premise communications functions for the
EST3 system.
Using the latest in digital signal processing (DSP) techniques, the
Modcom provides off premise communication features unavailable
on any other system.
The module has provisions for supervising two loop-start tele-
phone lines. The module features a modular jack for telephone line
connections. The Modcom’s configuration and firmware can also
be updated from any network node.
Modcom series modules occupy a single local rail space and
can be mounted in any node on the network. Any EST3 Control/
Display module can be mounted on the face of a Modcom series
module. Power for the Modcom is supplied by the EST3 system
supply.
