DTMR-PT [Dual Tone
Multifrequency Port (TTR)]
The Dual Tone Multifrequency Receiver Port (DTMR), also known as the
Touch-Tone Receiver (TTR), resides on the Tone Detector circuit pack (TN748,
TN420) or the TN756 Tone-Clock circuit pack. There are four Dual Tone
Multifrequency Receiver (DTMR-PT) ports and two General Purpose Tone
Detector (GPTD-PT) ports on a Tone Detector circuit pack. The DTMR port is
used to detect touch-tone digits that are placed on the 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, 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 Dual Tone Multifrequency Receiver Port maintenance object defines a set of
tests to verify that the DTMF digits detection capability of the DTMR port is
functioning properly. For all Tone Detector circuit pack level errors (DETR-BD),
refer to the XXX-BD (Common Port Circuit Pack) Maintenance documentation.
1. Where P is the port network number (1 for PPN and 2 or 3 for EPN); C is the carrier designation
(for example, A, B, C, D, or E); SS is the address of the slot in the carrier where the circuit
pack is located (for example, 01, 02, ..., etc.); and pp is the 2-digit port number (for example,
01).
