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, #, and *. 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.
