TRUNKING CHARACTERISTICS TABLE

D ——identifies the DEFAULT supervision option on the Generic 2 for the associated trunk group type and the only option for R2V3 and earlier releases.

-##——identifies a 1- or 2-digit number that corresponds to a particular DIMENSION PBX and/or System 85 signaling type. Beginning with System 85 R2V4, some trunk types may also be optioned (via administration procedures) for signaling types other than the default.

Note: Where appropriate the default designator (D) and the signaling type designator (-##) are combined to identify the default signaling type; for example, the table entry ‘‘D-1’’ means that the default signaling is ‘‘Ground Start.’’ The table entries apply to Generic 2 trunk connections. However, they may also be true for earlier versions of the switch.

Signaling Types:

1 —Ground start

2 —Ground start with party test

3 —Loop/reverse battery, wink start

4 —E&M immed in/immed out

5 —E&M wink-start in/immed-start out
