Disconnect supervision is also required to conference two
unguarded
external callers. The line must be equipped with disconnect
supervision from the central office for the Supervised option

Earth calling is only supported by a FEM connected to a
Norstar analog trunk module. The GATM does not support
Earth calling, even though the setting appears for the lines on
the module.
Tips: The duration of an open switch interval (OSI) before
Business Communications Manager disconnects a call is
programmed by the Disconnect timer setting. Refer to
