CO Line Loop Supervision (Talk/Hold Abandon)
CO Line Supervision is a Central Office (Telephone Company) feature. This feature allows for 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 distant end party hangs up, or when the caller is connected to voice mail
leaving a message and hangs up. The DX-80 receives the disconnect signal from the telephone company and forces
the CO line on-hook to release the system resource for other uses.
