Setting Call Abandon
CO line supervision is a Central Office (telephone company) feature. This feature provides advanced handling of call
connections when the distant-end party disconnects.
This function is especially useful when calls that have been placed on hold go unattended and the caller hangs up, or
when the caller is connected to voice mail, leaves a message, and hangs up.
The DX-120 receives the disconnect signal from the telephone company and forces the CO line on-hook to release the
system resource for other uses.
