Trunk Jack Types
Planning for trunks consists of deciding how to connect outside trunks to the
system, selecting options for how those trunks will work, and assigning trunks to
user stations.
Plan trunk connections by identifying trunk jack types and matching outside
trunks and auxiliary equipment to the jack types that support them.
Use the "Control Unit Diagram" on PBX System Form 1 and the local
telephone company trunk information list as you record connections on
PBX System Form 2c, System Numbering — Trunk Jacks.
The trunk jack type is determined by the type of module. The following table
shows the trunk jack types, the module types that contain them, and the outside
trunk or equipment they support.
