DTMR-PT (Dual-Tone Multifrequency
Receiver Port)
Dual-Tone Multifrequency Receiver ports (DTMR), also known as Touch-Tone
Receivers (TTRs), reside on the following circuit packs:
■
TN748
■
TN420
■
TN756
■
TN744B and TN744C
■
TN2182
■
TN2312AP
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 for maintenance of other
circuit packs (for example, IPSI circuit pack) and in placing a station-to-station
call. Calls originating from a hybrid station do not require a DTMR port.
The DTMR-PT MO implements a set of tests to ensure that detection of
touch-tone digits by the DTMR port is functioning properly. For any Tone Detector
circuit-level error (DETR-BD), see
‘‘XXX-BD (Common Port Circuit Pack)’’ on
.
