Action: The physical link may be poor - check it.
0406 SSCOP: STAT PDU - N(R) or list elements error
A STAT PDU has been received, either containing an unexpected value in the N(R)
field, or containing an error in list elements. Link recovery is being performed and
Signalling protocol is notified.
Action: The physical link may be poor - check it.
0407 SSCOP: USTAT PDU - N(R) or list elements error
A USTAT PDU has been received, either containing an unexpected value in the
N(R) field, or containing an error in list elements. Link recovery is being performed
and Signalling protocol is notified.
Action: The physical link may be poor - check it.
0408 SSCOP: PDU length violation
A PDU with a length outside the permitted length range for that PDU type has been
received. The PDU has been discarded and is otherwise ignored.
Action: Check configuration: does the configured UniVersion match the one
supported by the ATM switch? If not, fix it. Alternatively, this may be caused by a
poor physical link - check it.
0409 SSCOP: count SD PDUs being retransmitted
The indicated number of SD PDUs are being retransmitted, because so requested
in a STAT or USTAT PDU sent by the ATM switch.
Action: If excessive retransmissions, then the physical link may be poor - check it.
040A SSCOP: Credit condition - Lack of credit
SSCOP is currently blocked from transmitting any more SD PDUs, due to lack of
“credit”, i.e. we reached the top of the transmit window.
Action: Normally none, the situation should resolve itself by obtaining credit again
from the peer. If the situation does not resolve itself, check the ATM switch - is it
operating correctly on this port? If the situation occurs repeatedly, this may be
caused by an overloaded ATM switch.
040B SSCOP: Credit condition - Credit obtained
This annuls a previous “Lack of credit” event. SSCOP now has obtained “credit”
and is again allowed to transmit SD PDUs.
Action: None, situation is normal again.
0503 Cable-problem with connection to switch.
This message indicates a problem with the cable between this ATM Uplink and the
switch.
Action: Check cable.
