Ringing Patterns

Standard phones have these ringing patterns:

■

An outside call will ring . . . ring . . . ring.

An intercom call will ring-ring . . . ring-ring . . . ring-ring.

A transferred call or a held call ringing back will ring-ring-ring . . .

ring-ring-ring . . . ring-ring-ring.

NOTE:

If you use the system with PBX or Centrex lines, the PBX/Centrex ringing

patterns are not passed to telephones. Telephones use the ringing patterns

described here instead.

Dial Tones

Standard phones have two different dial tones:

■

Outside dial tone

is generated by your local telephone company to

indicate that you are connected with an outside line.

Intercom dial tone

is generated by the system to indicate that you are

connected with an 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 phone is set to select intercom first, as recommended in

this guide) is an intercom dial tone. To hear an outside dial tone, press [

Using the Switchhook

Some of the call handling instructions in Chapter 5 direct you to “rapidly press

and release the switchhook.” Pressing the switchhook for 1/4 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.

NOTE:

If your feature phone 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 (See “Recall”

in Chapter 5).

Limitations

Because standard phones do not have system line buttons, feature buttons, or

dedicated function buttons, basic call handling procedures are sometimes

different from those for system telephones. In addition, the following actions

cannot be performed at a standard telephone:

You cannot enter programming mode.
