European XFCOT Software Support
This feature supports international IPE trunks with new functionalities such
as supervision on loopstart trunk, PPM, and static pad switching.
The Generic XFCOT Software Support is a product improvement of this
feature regarding the pad switching, the trunk-to-trunk disconnection, and the
use of disconnect supervision for loopstart trunk in some features.
Meridian Mail
The Meridian Mail feature allows a caller to leave a voice mail message for a
person unable to be reached. Once the caller is connected to the voice mail-
there is a maximum duration allowed for the message after which the call is
disconnected.
Meridian Mail is allowed on disconnect supervised or unsupervised loopstart
trunks. If a caller on an unsupervised loopstart trunk disconnects while
accessing Meridian Mail, the call is disconnected when the connection-time
to the mail box exceeds the maximum duration.
Caller disconnection is detected by the disconnect-supervised loopstart trunk
on an XFCOT card and the caller is then dropped from the queue for
messaging service or from the mail box.
Periodic Clearing
Periodic Clearing is the sending of a periodic signal from the Meridian 1 to a
Central Office when an incoming call has been answered but is not in an
established state (for instance, ringing, held, parked). The connection is
disconnected if the originator goes on-hook.
The Periodic Clearing condition is timed by the disconnect timer (DCTI) to
prevent this situation from lasting for an extended time. When the DCTI timer
expires the trunk is disconnected.
The Disconnect Timer can be used without having the feature Periodic
Clearing configured particularly when the Central Office trunk has no
disconnect supervision. It can be disabled by setting the DCTI to 0 in LD 16.
A loopstart trunk can be marked as disconnect supervised. When it has a class
of service providing disconnect supervision, in Periodic Clearing condition
the trunk is disconnected when the calling station releases the call.
