TTR Settings
A TTR is allocated for 24 seconds at the beginning of the call and is reset to 24 seconds each time another digit is entered. If a digit is not dialed within the time frame, the TTR is removed from the call and the following occurs, depending on whether the call is an inside or outside call:
The system is factory-set to generate Touch-Tone signals for all lines/trunks, except tie trunks, when users dial outside calls. The factory setting can be changed for individual rotary trunks so that Touch-Tone signals are converted to rotary pulses for transmission to the Central Office.
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.
