AT&T Partner II - Manual (Page 21)

Industry-Standard Devices
Many industry-standard, single-line telecommunications devices will work with
the equipment controller:
Standard touch-tone, rotary, and cordless telephones (such as those you ■
might have in your home), including feature phones with built-in feature
buttons and lights
■ Fax machines
Answering machines ■
■ Modems
■ Credit card scanners.
Limitations
You can connect standard devices to your equipment controller, regardless of
the manufacturer. The following limitations apply:
The device must be industry-standard and non-proprietary. That is, it ■
cannot be made specifically for use on a particular telephone system.
(For example, you cannot connect an AT&T MERLIN® phone, because it
is specifically designed for use on a MERLIN system.)
NOTE:
You can connect a multiple-line device to the equipment controller, but for best
results it should be installed and used as if it were a single-line device.
The device’s Ringer Equivalence Number (REN*) cannot be greater than ■
2.0. (The REN is shown on a label on the device, usually on the bottom.)
Connecting and Using Standard Devices
You can connect a standard device so that it is on an extension by itself, or so
that it shares an extension with another piece of equipment (either another
standard device or an MLS- or MLC-model phone). An extension with two
devices connected to it is called a combination extension. For example, you
can connect an MLS-model phone and a standard phone to the same
extension, so that the standard phone can be used to place and receive calls in
the event of a power failure. To connect two devices on one extension, you
need an inexpensive AT&T 267F2 bridging adapter (two are provided with each
206 module).
Chapter 2 explains how to connect standard devices to the equipment controller
and how to combine them on a single extension. (See page 2-5 for installation
instructions for combination extensions.) For additional information on
programming and using fax machines, answering machines, modems, or credit
card scanners, see Chapter 7.
*
REN is a measure of the power it takes to ring a phone. A typical home phone line handles 4.0–5.0 RENs;
each extension jack in your equipment controller can handle 2.0 RENs.
