Install CAMA/E911 Trunk

Return to Task List

The CAMA/E911 feature requires the TN429C/D CO trunk circuit packs (or later suffix).

Port Networks (PNs) that include TN429C circuit packs used to interface to CAMA trunks require some CPTR resources to be either TN744D V2 or TN2182B circuit packs, since TTR/CPTR or General Purpose Tone Receiver (GPTR) resources are selected from the pool available in the PN when needed.

Compatibility Tone Clock, TTR/CPTR, and GPTR Circuit Packs denotes which of these circuit packs are compatible and which are not affected.

Compatibility Tone Clock, TTR/CPTR, and GPTR Circuit Packs
Circuit Pack	Description	Compatibility with CAMA Trunks in Same PN	Application	Notes
TN744 TN744B TN744C TN744DV1	Call Classifier - Detector	Not Compatible	Used globally	8 GPTR/call classification ports. Used for call classification only initially prior to G3V3.3. Becomes a GPTR resource in G3V3.3 and later. Use TN744DV2 if CAMA feature is to be supported.
TN744DV2	Call Classifier - Detector	Compatible	Used globally	8 GPTR/call classification ports. Required in PN supporting CAMA trunks if GPTR resources are required in excess of those on the TN2182BV2. Also required (if the TN768 or TN780 tone clocks are used) in place of TN748, TN744, and TN744B and TN744C.
TN748C TN748D	Touch Tone Detector / Call Progress Tone Detector	Not Compatible	Used in the U.S. and a few other countries	4 TTR and 2 CPTR ports. Used in combination with the TN756, TN768, or TN780 in many countries initially in versions prior to G3V3.3. Use TN744DV2 if CAMA feature is to be supported.
TN756	Tone Detector Generator	Not Compatible	Used in the U.S. and a few other countries	Tone detector/tone clock with 4 TTR and 2 CPTR ports. Used in combination with the TN748 in many countries initially in versions prior to G3V3.3. Used only with SCC/ESCC cabinets with no EPNs, no duplication, no ASAI. Use TN2182BV2 if CAMA feature is to be supported.
TN768	Tone Clock	Not Affected	Used in the U.S. and many other countries	Tone clock only, no TTR/CPTR functionality. Typically found with TN748 circuit packs in the U.S. Use TN744DV2 instead of TN748 with CAMA.
TN780	Tone Clock	Not Affected	Used in the U.S. (infrequently) for Stratum 3 clocking and used in many other countries	Tone clock only, no TTR/CPTR functionality. Typically found with TN748 circuit packs in the U.S. Use TN744DV2 instead of TN748 with CAMA.
TN2182 TN2182B	Tone Detector/ Tone Generator/ Call Classifier	Compatible	Used globally	Tone clock plus 8 GPTR/call classification ports. Use TN2182B if CAMA feature is to be supported.
