DTMR-PT (Dual Tone Multi-Frequency Receiver Port)
Dual Tone Multi-Frequency Receiver Ports (DTMR), also known as Touch-Tone
Receivers (TTR), reside on the following circuit pac ks:
■TN748 (mu-law companding)
■TN420 (A-law companding) [ G3r V2]
There are four Dual Tone Multi-Frequency Receiver (DTMR-PT) ports and two
General Purpose Tone Detector (GPTD-PT) ports on each Tone Detector circuit
pack. The DTMR port is used to detec t touch-tone dig its 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 d etect touch-tone
digits is essential for maintena nce of other circuit p acks (for example, Tone-Clock
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 maintenance objec t implements a set of tests to ensure that
detection of touch tone d igits by the DTMR port is functionin g properly. For all
Tone Detector circuit pack level errors (DETR-BD), refer to the "XXX-BD (Common
Port Ci rcui t Pack ) ".
