Single Line Telephone / Analog Device Support

The DX-80 system basic configuration has four (4) standard analog extension ports available. As the system
expands, additional APM4's (Analog Port Module-4 port) can be installed in place of Digital Port Module-8's (DPM8).
Analog extension ports are provided for connection of standard, two-wire, analog telephone equipment to the digital
network of the DX-80. Common uses of the analog extension ports are facsimile machines, modems, wireless and
wired single line analog telephones.
Each APM4 provides four dedicated DTMF receivers for decoding the dialed digits from the connected device. (Each
analog port has a dedicated DTMF receiver.) To place calls, the analog device must provide DTMF tone signaling,
which is decoded by the APM4 for call processing instructions. Each analog port provides twenty-five (25) – cycle,
(frequency) ringing for the attached analog device.
Since each APM4 provides dedicated DTMF receivers and ringing generators, and because the system has a non-
blocking digital ICM bus, the Single Line Telephones/Analog Devices are not traffic sensitive and do not require
special traffic balancing.

Conditions
a) Any single line (2500 type) telephone equipment can be connected to the system using one of the standard
analog ports available on the Analog Port Module (APM4).
b) Analog ports are dedicated to the Extension Directory Numbers system resource. These directory numbers
can be changed in Database Administration.
c) The allocation of DTMF Receivers (required resource to receive dialed digits from analog devices) is one to
one in the DX-80 system. That is, the system provides one (1) DTMF receiver per analog port for decoding
DTMF signals dialed by analog devices/SLT users.
