Clause 12
Insert clause 12 as follows:
”12 Response to protocol violations
An NL entity may receive a packet that is valid in accordance with IS0 8208 but is not valid when considered as part of the mapping
specified in clauses 6 to 11. In such cases it follows the actions given below:
a) Error conditions:
-
INCOMING CALL packet without Fast Select Facility;
-
INCOMING CALL packet without a TCN Facility;
-
CALL CONNECTED packet without EETDN Facility; and
-
CALL CONNECTED packet with a Selected QOS value, when present, that is not valid with respect to the CALL REQUEST
packet (i.e., the Selected value is greater than the Target value or less than the Lowest Quality Acceptable value).
Actions :
The NL entity shall transmit a CLEAR REQUEST packet across the DTE/DXE interface with a Clearing Cause field of “DTE
Originated.” It is recommended that the diagnostic code be set to 228 (or 224). The NL entity shall not signal any primitive to
the NS User.

b) Error conditions:
-
DATA packet with Q-bit set to 1 ;
-
DATA packet with D-bit set to 1 when "no use of Receipt Confirmation" has been negotiated at NC establishment; and
-
INTERRUPT packet when "no use of Expedited Data" has been negotiated.
Actions :
It is strongly recommended that the NL entity should transmit either of the packets given below across the DTE/DXE interface
with a Cause field of "DTE Originated." The Originator parameter of the resulting primitive signaled to the NS User, in either
case, shall be "NS Provider."
