If more TTRs are needed to support these services, 400 GS/LS modules can be
added (each module provides four TTRs).
shows the estimated number
of TTRs needed, depending on the call volume and the type of service.
is based on the assumption that the system already has basic telephones, remote
access, and tie trunks.
Table 41.
Number of TTRs Required
The touch-tone receiver (TTR) is allocated for 15 seconds at the beginning of the
call and decreases to 5 seconds as the number of digits dialed increases. Each
time the user presses another digit, the TTR timer decreases. If the user does not
dial a digit within the time frame, the TTR is removed from the call and, after about
24 seconds, the call is disconnected and the user hears a recording or a fast
busy.
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
