GENERAL DESCRIPTION
The PS 150 is designed to interface an ASL intercom
system (3-wire party line) to a telephone system
(2-wire). Communication can be achieved between a
telephone line and one or several ASL user stations
or between two ASL intercom systems via a
telephone line.
The unit is a combination of two interfaces.
One interface splits the intercom party line into a
separate audio input and output; the other interface
splits the telephone line into a separate audio input
and output. The inputs and outputs are internally
cross-connected.
