Feature Reference 555-661-110
Features
Touch-Tone or Rotary Signaling
2. Calculate the number of TTRs required by the voice messaging system(s)
(see
3. Calculate the number of TTRs needed for delay announcement devices,
both primary and secondary (see
announcement is used on a primary or secondary delay announcement
device, no TTRs are needed.
4. Calculate the total TTRs available on the system by adding the TTRs on
the modules that supply them (see
5. Compare the total number of TTRs required by the system to the total
number of TTRs provided by the modules in the system. If the number
required is greater than the number provided, one or more modules must
be added to the system.

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:
An inside call is disconnected after 24 seconds.
For an outside call, the user hears a recording or a fast busy tone; then the
call is disconnected.
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.
