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