4 Programming Procedures
Lines and Trunks
If you want to reassign a line/trunk to a different pool, you must remove it from the
current pool before you assign it to the new pool. Once you assign a line/trunk to a
pool, it can be assigned to a button only on a direct-line console operator position;
individual lines intended for personal use on telephones other than the DLC
console should not be assigned to pools.
DID trunks cannot be grouped in pools. Loop-start trunks are automatically placed
in pools and must be removed manually if used for paging loudspeakers, Music
on Hold, or maintenance alarms.
Dial-in tie trunks should not be grouped in pools if you intend to assign Pool
buttons on telephones.
!
SECURITY ALERT
In Release 6.0 and later systems (Hybrid/PBX mode only), do not assign
pools of non-local tie or PRI tandem trunks to Pool buttons or allow dial
access to them. When callers in your system need to use these pools for
outside calls, use ARS to direct the calls to these pools. Callers in your
system use normal calling procedures to reach extensions on networked
systems.
If you are using Automatic Route Selection, the main pool (factory-set dial-out
code 70) must contain loop- or ground-start trunks.
The system provides an error tone when a line/trunk is in use or if a loudspeaker
paging system, Music on Hold, or maintenance alarm is already assigned;
however, the system does not indicate the reason for the error tone.
NOTE: NOTE: NOTE:
This procedure applies to Hybrid/PBX mode only.
