Line Jack Types
The line jack type is determined by the type of module. The line jack type for the
800 CO-BRI module is BRI. Auxiliary equipment such as Music-On-Hold,
loudspeaker paging, and maintenance alarms cannot be connected to BRI line
jacks.

Jacks
For each 800 CO-BRI module, write "BRI" under "Jack Type. "
Jacks for Outside Lines
Each of the 16 BRI lines on the 800 CO-BRI module is associated with a logical
ID and a line number in the System Numbering Plan. For example, if the 800 CO-
BRI module is placed in slot 01 of the control unit, the 16 BRI lines are
automatically assigned logical IDs 1 through 16 and dial plan numbers 801
through 816. Figure 1-4 shows the directory and dial plan mapping,
The logical ID is shown under the "Log. ID" column and the line numbers are
shown under the "Trunk No. " column.
