Detector 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,...).

The GPTD (General-Purpose Tone Detector) ports, also known as CPTRs

(Call-Progress Tone Receivers), reside on the following circuit packs:

TN748 all suffixes (mu-law companding)

The GPTD port performs level measurements of test tones and to detect

call-progress tones. Examples of call-progress tones are dial tone, ring back,

busy, alert, confirmation, and recall dial. The abilities of the GPTD port to perform

level measurements of test tones and to detect call-progress tones are essential

for maintenance of other circuit packs (for example, Tone-Clock).

The GPTD MO defines a set of tests to ensure that the GPTD port's

general-purpose tone detection is functioning properly. For every Tone Detector
