Drop Reason
(cont’d)
Endpoint Clearing received from DS1 - the disconnect came from
the endpoint. The endpoint notified the MCU that it intended to
disconnect.
Far-end Clearing received from DS1 - the disconnect came from
either the network or the endpoint.
Handshake Either framing was never found (the endpoint could not
complete initialization - problems finding Frame Alignment Signal
(FAS), Multi Frame Alignment (MFA) and getting a corrected coded
cap-set) or framing was lost for some time (over 40 seconds) and the
endpoint was disconnected.
IDtimeout The MCU has not received response to the
UIN/password Query from the H.320 user after three attempts. Each
attempt has a system administered timeout period.
Internal MCU has a problem allocating trunk resources necessary
to route the dial-out call for the specified dial-numbers. This problem
can be associated with routing pattern or trunk associated translation
(for example, TAC specified in the dial-out number or routing pattern
points to a trunk group without members), or it can indicate a lack of
trunk resources (for example, all trunk members are maintenance
busy or all in-service members are busy on a call).
Network Clearing received from DS1 - the disconnect came from the
network. The endpoint that had the disconnect notification capability
disconnected without notifying the MCU.
Not-MCU The dial-out destination number(s) of the “CAS” extension
has terminated to a number that is not a dial-in cascade MCU
extension.
No-ring This dial-out drop reason occurs when the call has been up
for 30 seconds and no ringing is detected.
Reorder This dial-out drop reason occurs when the MCU detects
that there are no available trunks in the network to place the call. This
drop reason is detected by MCU CPTR resources. See “Dial-out” for
a description of CPTR usage.
