Features and Services
Caller disconnection during park state is detected by a disconnect supervised
loopstart trunk on an XFCOT card. The disconnected caller is then dropped
from the parked DN.
Camp-On
The Camp-On feature allows an attendant to route one additional call to a
busy DN so it can be rung when it becomes free. If the busy DN is not free
after a customer-defined time, the call is recalled to the attendant.
A call from a loopstart disconnect supervised or unsupervised loopstart trunk
can be camped on. If a caller on an unsupervised loopstart trunk disconnects
while the call is camped on, it is detected when the call is recalled or
answered.
Caller disconnection during Camp-On operation is detected by a disconnect-
supervised loopstart trunk on an XFCOT card and the camped on call is
dropped.
Digital Trunk Interface (DTI) Pad Switching
The DTI pad process intervenes when a DTI port is involved in a connection.
It is independent from the normal pad and it handles the DTI port side and the
other port side.
This process is changed to handle XFCOT units when the North American
Transmission Plan is selected as XUT units.
Direct Inward System Access
This feature allows selected external users to access the Meridian 1 switch by
dialing a special directory number, and to use some features of the system as
an internal station.
A Direct Inward System Access (DISA) call is allowed on a disconnect
supervised or unsupervised loopstart trunk. If a caller on an unsupervised
loopstart trunk disconnects during a DISA operation, it is detected by a dial
time out or when the call is answered.
Caller disconnection during a DISA operation is detected by a disconnect-
supervised loopstart trunk on an XFCOT card and the operation can then be
ended.
