There are four Dual-Tone Multifrequency Receiver (DTMR-PT) ports and two General Purpose
Tone Detector (GPTD-PT) ports on the TN748, TN420 and TN756 Tone Detector packs. There
are eight GPTD-PT ports on each TN744, TN2182 and TN2312AP circuit packs.
The GPTD ports can be used for TTR, call progress tone detection, call prompting, MF
signaling, dial tone detection, CO answer detection and OCM call classification.
The DTMR port is used to detect touch-tone digits that are placed on the Time Division Multiplex
(TDM) bus. Examples of touch-tone digits are digits 0 through 9, digit #, and digit *. The ability of
the DTMR port to detect touch-tone digits is essential in placing a station-to-station call. Calls
originating from a hybrid station do not require a DTMR port.
For any Tone Detector circuit-level error (DETR-BD), see XXX-BD (Common Port Circuit Pack/
Media Module).
