5.5.1.2 Clearing down Exchange-to-Exchange Connections
Digital-Digital (D-D):
The public network sends the PBX a release signal once the external call partners
of an exchange-to-exchange connection have finished the call. The connection is
then cleared down by the PBX.
Without a release signal, the PBX cannot clear down an exchange-to-exchange
connection.
The amount of time between completion of the call and the sending of the release
signal depends on whether the exchange-to-exchange connection is set up end-
