TONE DETECTOR (TN748)

Two Call Progress Tone Receiver (CPTR) ports are provided on each TN748 Tone Detector cir-

cuit pack alongside the four Touch-Tone Receiver ports. CPTRs are required to provide dial tone

detection for the enhanced Automatic Route Selection, Terminal Dialing, Abbreviated Dialing, and

Last Number Dialed features. High usage of Terminal Dialing to locations outside the system

may require a greater number of CPTRs and should be referred to your Technical Service Center

(TSC) for review.

Note that up to 20 TN748s my be used in G1 systems, up to 10 in G3i or G3i-GlobaI systems,

and up to 50 in G3r systems.

In the following calculations, do not include TN748s that are provided as standard equipment.

Note:

For G1 single-carrier systems, the TN768 Tone Clock circuit pack is used instead of

the TN756 Tone Detector/Generator circuit pack when the duplication option, DS1

Tie Trunk (TN722), or DS1 Interface (TN767) circuit packs or ISDN-PRI is used.
