A-45 Attendant Camp-On with Tone Indication - CCIS
Operating Procedure (cont’d)
5. Stations (a) and (b) both go on-hook Note 2; (b) is rung, and (c) receives ringback tone.
6. Station (b) answers; Station (b) and Subscriber (c) are connected with each other.
Note 1: If the Attendant presses the BV key instead of the RELEASE key, the Attendant bridges into the Station (b)
side and, as a result, a three-way connection is set up. In this case, both (a) and (b) are bridged into the
connection. The Attendant sets Camp-On by pressing the RELEASE key.
Note 2: Instead of on-hook by Stations (a) and (b), if (b) switch hook flashes and dials the Call Hold Access Code,
(b) can answer Subscriber (c) (C.O.line party), and (a) is held on the line.
If (b) switch hook flashes and dials the Call Hold Access Code once again, (b) can return to the connection
with (a). In this case, Subscriber (c) is held on the C.O.line.
Service Conditions
1. Only one incoming call can be camped on to a particular station at any given time. Multiple CAMP-ON
is not allowed.
2. Calls that remain camped-on for longer than the predetermined time will initiate AUTOMATIC RECALL
- CCIS [A-71].
