160 (CLEAR,
RESET)
DTE-specific
signal (generic).
CALL INDICATION with reverse charge
requested has been received, and reverse charge
is configured to be rejected by system.
CALL INDICATION with reverse charge
requested has been received by IP and reverse
charge is configured to be rejected for that
IP/X.121 address pair. Check is done via IP to
X.121 address map table.
CALL INDICATION with reverse charge
requested has been received by IP and no entry
in the IP-to-X.121 address map table exists for
this X.121 address. Internal problem which may
be generated by components of X.25/9000
architecture.
161
(RESTART)
DTE
operational.
Level 2 is coming up or a SABM frame is
received. System sends RESTART REQUEST
indicating host is up.
162 (CLEAR,
RESET)
DTE not
operational.
Either level 3 or level 2 detected as down.
Request delivered when network interface was
not operational. Condition usually results in an
error returned to the application instead of
CLEAR. Diagnostic is used when RESTART
INDICATION has been received by interface.
Interface is going down. RESTART REQUEST
was sent on network.
163 (CLEAR,
RESET)
DTE resource
constraint.
Lack of memory to establish, reset, or clear a call,
to process data, expedite data or
acknowledgments, or to perform internal
operation. This may indicate lack of network
memory, or resource constraints on card. When
resource constraint appears on connected circuit,
CLEAR will be sent only if no recovery is
possible.
