Subscription Option - Incoming Calls Barred
Subscription Option - Outgoing Calls Barred
This covers the following CCITT subscriptions:
Incoming Calls Barred
This facility, if subscribed to, prevents incoming calls from being presented
to the DTE.
Outgoing Calls Barred
This facility, if subscribed to, prevents the network from accepting outgoing
calls from the DTE.
If subscribed to, these facilities apply regardless of what logical channel
group numbers are subscribed to.
These facilities is not normally supported on UK since the same effect can
be achieved by providing outgoing logical channels only (LCGN 6).
