Network Management Features

Public Network Call Priority

Public Network Call Priority provides intrusion, retention, re-ring, and mode of release control to switches on public networks. It allows you to give priority to toll calls in areas where trunks and lines are in short supply.Many of the capabilities of this feature are similar, but are referred to by different names in different coun- tries. Public Network Call Priority can include:

■Call Retention

■Mode of Release Control

■Forced Disconnect

■Intrusion

■Re-Ring

NOTE:

All of these features are designed for special network conditions in countries outside the United States, particularly Spain, Russia and China.

Call Retention

When you make an emergency call from an analog or digital telephone and then hang up, the call is not disconnected, but put on hold. You can then reconnect to the emergency call by simply picking up the receiver again.

Mode of Release Control

Mode of Release Control is similar to Call Retention in that it retains calls, only in this case it retains calls based on administrable control parameters. The feature applies to all types of calls: incoming, outgoing, toll, local, or service. You can administer three types of control:

■Calling Party Control does not release the line until the calling party picks up.

■Called Party Control does not release the line until the called party picks up.

■First Party Control releases the line to whomever picks up first.

Forced Disconnect

This feature allows a toll network operator to disconnect a called party from a local call and connect an incoming toll call. The parties on the local call hear a warning tone before being disconnected. The disconnect is only permitted on single-station local calls and will not occur to conference calls, calls on hold, or other toll calls.
