Automatic Line Selection
Automatic Line Selection automatically selects a preferred line button based on the class of service and line priority.
The line preferences are as follows, in order of selection priority:
Line Preference | CLS | Description |
---|---|---|
Manual | A line is manually selected. If idle, dial tone is returned. If ringing, the call is answered | |
Incoming Ringing Line | IRA | On going off-hook, the first ringing line is automatically selected and answered |
Incoming Non-Ringing | NIA | As above (IRA), but for lines which appear but don't ring (eg, SCN xxxx) |
Outgoing Line | OLA | On going off-hook, the first idle line is automatically selected and dial tone returned |
Prime Line Selection | On going off-hook, if a line isn't manually selected, the Prime Line (KEY 0) is selected |
Notes:
- Last Preference Key (
LPK
) specifies the last key to be scanned for line preference. - If a set has more than one line button, add "
CLS IRA
" (andLPK 1
?) so that a non-Prime Line incoming call is automatically answered when picking up the receiver.
