Operation
1. Incoming call arrives to a LCOB line which has a FSK or DTMF CID detection optional
board(CPCU for FSK CID, CPCUD for DTMF CID).
2. Optional board on LCOB detects CID signal.
3. Ring is distributed to ring-assigned stations with CLI.
Condition
1. If an incoming CO is assigned to multiple SLTs of a same slot, the CO rings are generated
sequentially with 1 second interval to the SLTs. And CLI is displayed on SLT after first ring.
2. For CLI display on SLT, ring phase (PGM 182, Button 4) more than 4 seconds is recommended.
If Ring phase is less than 4 seconds, some of the SLT can not receive CLI display signal.
3. CLI is not transferred to the SLT for screened transfer because type I CID is serviced for SLT.
4. For CID detection on LCOB, optional board(CPCU for FSK CID, CPCUD for DTMF CID) should
be installed on LCOB.
