Receiver Port)

(in Alarm Log)

UU is the universal cabinet number (1–64 for ATM PNC, 1–44 for CSS PNC). C is the carrier designation (A,

B, C, D, or E). SS is the number of the slot where the circuit pack resides (01–21). pp is the 2-digit port number

(01, 02, 03 ...).

Dual-Tone Multifrequency Receiver ports (DTMR), also known as Touch-Tone

Receivers (TTRs), reside on the following circuit packs:

TN744B and TN744C

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
