supported by the particular model of
ISDN Gateway, because the port is not
applicable or not licensed or because it
has been explicitly disabled by the user
(see Configuring ISDN ports settings).
Note that for ISDN GW blades the
number of licensed ports depends on
the number of PRI port licenses
allocated to the blade.
