Features
Touch-Tone or Rotary Signaling
Rotary signaling can be set for Delay or No Delay. Delay is the factory setting; it
makes the rotary pulse inaudible to the telephone user and delays sending the
dialed number from the control unit to the line/trunk until the user is finished
dialing.
Considerations and Constraints
Tie trunks are set up either to send signals to or receive signals from another
PBX, or they are set up to be bidirectional, that is, to send and receive signals. If
the system has bidirectional tie trunks, the signaling can be set for both directions
independently. For example, outgoing (outmode) signaling can be rotary and
incoming (inmode) can be touch-tone. Consult the local telephone company for
more information.
The audible feedback for touch tones generated when a user presses a dialpad
button can be heard by any user who shares a personal line or a Shared SA
button with the telephone that is used to make a call. Therefore, when dialing
confidential numbers such as passwords or account information, the user should
take precautions, such as activating Privacy, to prevent others from hearing the
touch tones.
Touch-tone dial mode cannot be programmed for DID trunks that are immediate
start.
Touch-tone dial mode cannot be programmed for incoming, immediate tie trunks.
Touch-tone, single-line telephone users cannot make calls using individual
lines/trunks programmed for rotary operation. The touch-tone signals generated
from the telephone while dialing are transmitted to the central office at the same
time the rotary signals are sent by the system. The central office receives both
signals and cannot process the call.
Mode Differences
In Behind Switch mode, the factory setting for rotary signaling should be changed
to No Delay.
