CO Line Type Assignment (Trunk Type)

Each CO line can be assigned as "PBX," "CO Line," "EMPTY," "CO DEV," or
"PAGE." These designations provide for the following possible CO Line circuit
connections:
CO ‐ CO type line circuits are standard interface lines that require no special
handling for advanced system features.
PBX ‐ PBX Line type invokes system automatic operations for handling of
PBX ports. When a programmed PBX Trunk access code is dialed, the system
is alerted that the user is accessing a telephone company facility to make a
network call. When this occurs, the system monitors digits dialed after the
PBX access code and compares them against the Allowed Digit Interval table
in that station's Class of Service. The programmed PBX Trunk access code also
notifies the system that a pause should be inserted when re‐dialing telephone
numbers dialed on that CO line beginning with the PBX access code. This
operation applies for Speed Dial, Last Number Redial, Saved Number Redial,
Memo Pad, and Automatic Redial.
EMPTY ‐ Assignment reserved for CO lines equipped on the system, but not
connected to telephone company, network facilities. The EMPTY type
eliminates the CO Line from access by system features that automatically
access CO Line resources.
CO DEV ‐ CO DEV type is provided to mark a CO Line circuit as being
connected to special apparatus. This type effectively removes the CO Line
circuit from automatic access by system features while maintaining its direct
accessibility for the specific purpose of its connection. (Typical use would
include connection of ancillary analog intercom calling device.)
PAGE ‐ PAGE type is provided to mark a CO Line circuit as being connected
to special apparatus. This type effectively removes the CO Line circuit from
automatic access by system features while maintaining its direct accessibility
for the specific purpose of its connection. (Typical use would include
connection of ancillary paging equipment.)
Default Settings
At default CO Line Type is set to CO for all CO Lines.
