Dial Tones; Using The Switchhook; Single-Line Telephone Limitations - Avaya PARTNER ACS Installation And Use Manual

If you use the system with PBX or Centrex lines, the PBX/Centrex distinctive ringing
patterns are not passed to telephones. Telephones use the ringing patterns
described here instead.

Dial Tones

Single-line telephones have two different dial tones:
Outside dial tone is generated by your local telephone company to indicate that you are
I
connected with an outside line.
Intercom dial tone is generated by the system to indicate that you are connected with an
I
inside line. You hear this dial tone when you are making an inside or intercom call.
To hear the difference between the two dial tones, lift the handset. The dial tone you hear
(assuming the telephone is set to select intercom first, as recommended) is an intercom dial tone.
To hear an outside dial tone, press

Using the Switchhook

Some of the instructions in this guide direct you to "rapidly press and release the switchhook."
Pressing the switchhook for 1/2 to 1 second sends a signal over the line called a switchhook flash.
However, do not press the switchhook too quickly. If you press the switchhook and nothing
happens, try again and press it a little longer.
If your feature telephone has a button labeled "Recall" or "Flash," use the button instead
of pressing the switchhook. If you use the system with PBX or Centrex lines, your PBX or
Centrex documentation may tell you to press the switchhook to access PBX or Centrex
features. Use the Recall feature instead.

Single-Line Telephone Limitations

Each tip/ring device requires one touch-tone receiver to be available in order to dial a call
(intercom or outside) or to activate a feature by using a code. Each PARTNER ACS processor
module has two touch-tone receivers, each 012E module has ten touch-tone receivers, each 206
module has one touch-tone receiver, and each 400 module has two touch-tone receivers. The
combination of modules in your system determines the number of tip/ring devices that can dial
simultaneously. For example, if you have one PARTNER ACS processor module, two 206
modules, and two 400 modules, eight tip/ring devices can dial out at the same time. If nine tip/ring
devices try to dial out simultaneously, the ninth device does not get dial tone until one of the other
eight finishes dialing. (PARTNER MAIL VS contains its own touch-tone receivers and does not
require any from the system.)
