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,

3. When the Override 1st CO line Group is
enabled, the system will search for the next
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’).
4. A station which is not permitted to access a
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.

CO LINE QUEUING
Description
When a user encounters a busy tone during
accessing a CO line or a CO line group, the user
can request a call back (queue) when the CO
line is available. The station will receive a call
back when the busy CO line or a CO line in the
CO line group becomes available.
Operation
To activate queuing while receiving busy tone,
Press the [CALLBK] button.

2. A station can make only one CO line queuing
request at one time. If the station tries to
make another CO line queuing, the previous
one is canceled and the later one is available.
3. When the queued CO line available, the
station will receive ring signal regardless of
station signal mode.
CO LINE RING ASSIGNMENT
Description
Each station in the system can be programmed
to provide an audible signal when the system
detects an incoming call on assigned CO lines.
Separate ring assignments are made for day,
night and weekend mode operation. Also, the
audible signal at the station can be delayed by 1
to 9 ring cycles allowing other stations to answer
the call first.
Operation
The LED of [DND/FOR] button and LCD on the
attendants’ keyset indicate current ring mode;
Day mode (LED off, LCD shows station number
and ICM answer mode.) -> On-demand mode
(LED is flashing, LCD shows ‘ON DEMAND’) ->
Night mode (LED is lighting, LCD shows
‘NIGHT’ ) -> Weekend mode (LED is flashing,

Facility} button after seizing a CO line
(ISDN), the system will send the dialed
digits as Keypad Facility IE instead of Called

CO line (ISDN).
4. When this feature is activated, the system
starts to send Keypad Facility IE instead of
Called Party Number IE regardless of
CONNECT message from the network
unless pressing {Keypad Facility} button to
deactivate it. So the system will continue to
send Keypad Facility IE instead of DTMF
tone even after CONNECT message is
received from the network.
5. If the Speed Dial is stored with [FLASH] as
the first digit for ISDN line and the station
has the Keypad Facility Access authority, the
digits after [FLASH] command will be sent
as Keypad Facility and the feature will be
deactivated after sending all digits.
6. When any of the following features are
encountered after the Keypad Facility is
activated, the feature will be deactivated
automatically;
- Pressing function keys as [REDIAL],
