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.

1 —Ground start
2 —Ground start with party test
