Functional Description
• shutdown (port status)
When shutting down a single subscriber the network element requests a
blocking from the softswitch or local exchange. The softswitch or local
exchange allows the blocking if the subscriber state is idle. An ongoing
call is not interrupted. There is no SHT (shutdown timeout) alarm.
• unlock (port status and unit status)
With the unlock command the subscriber becomes unblocked.
The operational state shows the state as defined and forced by the signal-
ling. The possible states are:
• enabled
• disabled.
The following table gives some explanations about administrative and opera-
tional states according to ETS 300 376-1, Annex A:
Only the user ports in the state “unlocked” / “enabled” are really in operation
and ready to do calls. In all the other states, the associated user port is
either blocked or considered as blocked.

Administrative
state
Operational state Explanation
locked enabled The port has been locked by the manage-
ment system of the NE and there are no
local fault conditions, regardless of any
knowledge about the softswitch or local
exchange side.
locked disabled The port has been locked by the manage-
ment system of the NE and there is an
NE fault, regardless of any knowledge
about the softswitch or local exchange
side.
unlocked enabled The port has been unlocked by the man-
agement system of the NE and there is
no NE fault and no blocking by the softs-
witch or local exchange.
The port is ready to do calls.
unlocked disabled The port has been unlocked by the man-
agement system of the NE and there is
an NE fault or a blocking by the signalling
(H.248/MEGACO or SIP or V5).
This state is also entered as part of the
unblocking procedure if the NE sent
UNLOCK to the port object and an
acknowledgement from the signalling
needs to be awaited.
shutting down undefined The subscriber port state is “busy”. The
administrative state will become locked
as soon as the subscriber terminates his
call or the timeout of 30 minutes has
elapsed.
