Trunk Mode; Ans Mode - Nortel Modular ICS 6.0 Installer's Manual

Trunk mode

Trunk mode allows you to specify either disconnect
supervision or unsupervised. Disconnect supervision, also
referred to as loop supervision, releases an external line when
an open switch interval (OSI) is detected during a call on that
line. This prevents the line from remaining unavailable for
other Norstar users.
Press CHANGE to select the setting: Unspr or Super.
• Unspr (the default) turns disconnect supervision off for the
line.
• Super assigns supervised mode, if supported by the line.
otherwise, the line functions as unsupervised.
