Demonstrating Ringing Frequencies
Procedure To demonstrate ringing frequencies:
1
Press the <R-FRQ> key. You see the first ringing
frequency listed on the display and you hear it.
(Ringing frequencies determine the pitch of the ring.)
The sample of this frequency is repeated about every
three seconds until you press the <R-FRQ> key again.
2
Press the <R-FRQ> key a second time to display and
demonstrate the second ringing frequency.
Subsequent key presses scroll through the different
ringing patterns until you return to the OFF
designation.
A list of the ringing patterns that can be demonstrated
follows. Remember, this facility only permits you to
demonstrate these patterns. Patterns are changed at
the CommCenter-CMAT by your system
administrator.
