Touch-Tone or Rotary Signaling 43
At a Glance 43
Description 43
Touch-tone, tip/ring devices, such as single-line telephones or fax machines, are
equipped with a dialpad that generates dual-tone multifrequency (DTMF) signals
when a dial button is pressed. Analog multiline and MLX telephones are equipped
with dialpads that generate digitally coded signals when a dial button is pressed.
The duration of the signal sent is 50 milliseconds (50 ms) and is not adjustable.
A touch-tone receiver (TTR) is required either to make calls from tip/ring
equipment or to use the Remote Access feature. TTRs are provided on 400 (LS),
400 GS/LS, 800 DID, 008 OPT, 800 GS/LS-ID, 016 (T/R), and 012 modules.
Normally, these TTRs are sufficient to handle the calls originated from these
modules. However, additional TTRs may be needed to support the following
services:
■ Tie trunks and T1-emulated tie trunks set for DTMF signaling
■ Tandem tie trunks and T1-emulated tandem tie trunks used in a private
network (Release 6.0 and later systems)
■ Remote Access
