The basic PACTS128 contains all the
equipment necessary to call from 16 originating lines and eight
incoming 1004 Hz lines. Modules can be added as needed to increase
capacity to 128 outgoing and 16 incoming lines. The unit consists of a
CPU-Speech-Modem module, power supply module, line monitor module, up
to two 8-line milliwatt termination modules, and up to eight 16-line
switch modules. The PACTS128 is accessible through the
CPU-Modem-Speech module from a PC running PAT System software and
equipped with a modem. The unit also is equipped with an RS232C
interface for connection to an external computer.
The 14-slot Rack-Mount Chassis is fully
wired. The chassis occupies six vertical inches and fits in a standard
23-inch bay; adapters are supplied for 26-inch bays. The chassis is
designed with an open slot wired for future use so the unit can easily
keep pace with advances in technology.
The CPU-Modem-Speech module is equipped
with DSP technology to detect SIT, call-progress, and various other
test-circuit tones. The unit also can detect the presence of speech
and play back a digitally recorded message. Each connected line is
checked for tip and ring reversals.
