The Powers Telecommunications
Interface Unit (TIU)
provides an interface between a Powers Stand-alone
Control Unit (SCU) and both public and private phone
lines on an intermittent basis.
This communications
interface will dial a Powers Central Processing Unit
(CPU) and/or dumb terminal to remotely report alarms
or other user-defined conditions.
The Powers Telecommunications Interface Unit will also accept a call from a
central Powers CPU or a dumb terminal (manually
accessed).

The Powers TIU can answer calls from a Powers

a Powers TIU has access to the entire Powers SCU
network, not just the Powers SCU In which the

The Powers TIU provides the functions necessary for
both auto-answer and Auto-Dial communicatrons.
Using
a Powers TIU, an operator can pre-program the system
to communicate on a regular basis and as the result of
In addition, when combined with

the custom programming capability of the Powers SCU,
calls can be directed to different phone numbers based
on time of day (i.e., call the owner’s computer during
the day . . . call a remote “manned” dumb terminal at
nrght).
When an alarm occurs at any unit on the network, the
Powers TIU will establish communications
by dialing the
Powers CPU or dumb terminal. Once the Powers TIU
establishes communications,
the system annunciates
the alarm through the Powers CPU or terminal, as
though the Powers CPU or terminal were directly
connected at the Powers SCU Network.
The Powers
TIU can also place calls as necessary to report an alarm
to two locations (two alarm devices).
The SCU can
store up to slxteen 20-digit numbers. allowing It to be
used with various Independent long distance companies.
Additionally. the Powers TIU supports both Touch-Tone
and rotary dialtng to facilitate interface to an existing
PBX.
Finally, for remote buildings having only one Powers
SCU, the Powers TIU can also support a local user
interface device for local control and monitoring.
When
this is done, the Powers SCU’s FE-232 port IS shared
between auto-dial and user Interface functions.
