Description
Explanation
65 (CLEAR) Facility/
registration
code not
allowed.
Packet size negotiation, Window Size
Negotiation or Throughput Class
Negotiation facility codes found in the
facility field of the call setup packet
when corresponding negotiation had
not been configured. In CALL
REQUEST, condition results in error
returned to user instead of generation
of CLEAR.
If facility checking was configured, a
facility code not allowed by configured
level (1980 or 1984) was found before
the first facility marker. In CALL
REQUEST, this condition results in an
error returned to user instead of
generation of CLEAR.
If facility checking was configured
along with rejection of duplicate
facilities, a combination of invalid
facility codes was detected.
The combination may indicate that the
basic and extended format of given
facility are present or that both the
Closed User Group and Closed User
Group with Outgoing Access facilities
are present. In CALL REQUEST, this
condition results in an error instead of
a CLEAR.
Facility marker 00 3B (hex) found,
which corresponds to “internal”
facilities. This facility marker is not
allowed by either application or
network. In CALL REQUEST, this
condition results in an error returned
to the user instead of CLEAR.
