1. Calling Party Control Signal (CPC) incoming
The Host Exchange can send a short disconnect signal on completion of the call.
The Timer Prog Step [405] can be set to the minimum disconnect signal time.
If too short a time is set, the PBX may see random line conditions as the CPC signal
and release the call.
If too long a time is set, the CO Lines will lockup if the customer is using CO – CO
call forward or transfer.
Note:
Some older Answer Machines may treat the Recorder Tone returned to an extension
after CPC signal detection clear down as an ongoing call and continue to record.
2. Calling Party Control Signal (CPC) outgoing
When the CPC signal is detected on the original CO Line the PBX sends a CPC
signal to the established CO Line.
This would be used in a CO to CO connection.
Enabled using Prog. Step 415.
3. Host working
• If the Host PBX codes are entered in Prog. Step 411 the Pause time [412] will be
inserted after the Host code has been dialed.
• Register Recall signal can be modified by Prog. Step 413, to send a signal to the
Host PBX.
4. Reverse Signal Assignment
If set to detect (Prog. Step 416), on reversal the PBX starts the call duration timer and
opens the speakerphone speech path.
