CO LINE ACCESS
Description
Stations are permitted to access to outgoing CO
lines based on CO Line Group Access
programming. Keysets may use flexible buttons
assigned to access a CO line or a CO line Group
(Pool Flexible button) and loop flexible buttons. If
allowed, stations without individual CO line
button can access individual CO lines using dial
codes.
Operation
To access a CO line from a keyset,
1. Lift the Handset or press the [MON] button.
2. Press the desired CO line, Pool, or Loop
button.
3. Or, dial the individual CO line access code,
CO group access code, or the first CO line
access code from the accessible group.

accessible CO group until a CO line is
available if there is no available CO line by
dialing CO line group access code (‘9’ or ‘0’).

CO line will hear error while trying to access
a CO line, but the station can receive a
transferred CO line call.
5. The CO line choice (Round-robin or Last
Choice) is determined by Admin
Programming (PGM 160-BTN 3)
6. If the CO line is BRI, when a user tries to
seize B1 but the network requests to serve
B2, the system can change CO line to B2.
(There is a {B2 CO} button or {LOOP}
button.)
CO LINE GROUPS
Description
The system provides grouping of similar types of
CO lines. The groups are used for common
access by stations assigned to access the
groups. CO lines are selected from the group
based on the assigned method, round robin or
the last line, in order to minimize call collision
(glare).
Operation
The number of CO line group in each system is 8
in LDK -24 system. You can access a CO line
group by dialing 8 8 and the CO group number.
The first CO line group in each system (00) is
directed line group (it can be used with CO
button) and the last CO line group is unassigned
line group.
