C-20 Centralized Attendant Service (CAS)
Operating Procedure (cont’d)
Remote Hold
1. The Attendant converses with a central office party.
2. The Attendant presses the SHF key; hears special dial tone.
3. The Attendant dials the Remote Hold access code (one or two digits); the central office party is placed in
the hold state at the satellite system, and the Attendant hears the hold confirmation tone (five, 50 msec.
bursts of 440 Hz).
4. The Attendant presses the RELEASE key to make the release link trunk available to serve another call.
5. If the central office party remains in the hold state for longer than the prefixed time, the satellite system
reconnects the central office party via the release link trunk.
6. Upon receiving the recall on the hold call, the ATTENDANT CONSOLE(s) [A-3] will display the
incoming CAS call by flashing the CAS lamp.
7. The Attendant answers the incoming CAS call by pressing the CAS or ANSWER key; hears the hold recall
identification tone (five, bursts of 440 Hz).
8. The Attendant is now able to complete the call.
Operator Call
1. When an operator call code (one or two digits) is received from a station or TIE Line trunk in the satellite
system, an operator call is directed to the main system via release link trunks.
2. Upon receiving the incoming CAS call, the ATTENDANT CONSOLE(S) [A-3] will display the incoming
CAS call by flashing the CAS lamp.
3. The Attendant answers the incoming CAS call by pressing the CAS or ANSWER key; hears the operator
call identification tone (two, 100 msec. bursts of 440 Hz).
4. At the expiration of this tone, the Attendant converses with the calling party.
5. The Attendant's procedure for serving this call is similar to that for an LDN call.
Call Transfer - Attendant
1. After any call is completed to a satellite station, the called party station can call the Attendant in the main
system to transfer the calling party to another station in the satellite system. The operation of this feature
is similar to that of an operator call.
2. The Attendant answers the incoming CAS call by pressing the CAS or ANSWER key; hears the operator
call identification tone (two, 100 msec. bursts of 440 Hz).
3. After answering the call, the Attendant presses the SHF key, causing the satellite system to disconnect the
station that dialed the operator call code and connects to the calling party.
Night Service for the Incoming CAS Call in the Main System
1. In night mode, the incoming CAS call is directed to a night station to be answered.
2. When the night station answers that call, the night station hears the identification tone depending on the
call.
3. The night station momentarily switch hook flashes; hears the special dial tone from the main system.
4. Dials the Flash Signal Sending access code (one or two digits); hears special dial tone.
5. After this, the operation of the night station is similar to that of the Attendant.
6. The night station must be provided with DTMF signaling.
Service Conditions
The following applies to a NEAX2400 IPX used at the main CAS location (Attendant location)
1. The number of Release Link Trunks is determined by overall satellite to main location traffic requirements.
