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, 400
GS/LS, 800 DID, 008 OPT, 800 GS/LS-ID, 016, 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 DS1-emulated tie trunks set for DTMF signaling
■
Remote Access
■
Account Code Entry
■
Authorization Codes
