Resolved Caveats for Release 7.0.x
Maintenance and Administration
CSCsd67191
A node might rarely report DCC failure and loses all connections when it is participating in a large
network with several host routes, where multiple netJobAdd calls are likely, which eventually deplete
the allowable ring buffer. When the MCC driver fails to complete the add it stops responding to receive
packets and the DCC fails. Proper subnetting and OSPF summarizing will avoid excessive host routes,
reducing the chance for such a scenario. This issue is resolved in Releases 6.2, 7.0.2, 7.2, and 8.0.

Rarely, autoprovisioned audits (those with the unique ID of 0) can become stranded after a bulk roll of
VC LO circuits prior to deletion of those circuits. If an attempt was made previously to delete all such
circuits, you can use subtractive logic to discover which circuits have become stranded. That is, matrices
indicating usage in the node view, Maintenance > Cross-connect > Resource Usage window will indicate
stranded circuits.
Once you have identified that there are stuck STSs, go to the card view for each affected trunk card and
view the Maintenance > Loopback > SONET STS tabs. From here you can view all used STSs, including
any stuck STSs. Determine which STSs in your network have no circuit associated with them, then create
and subsequently delete a LO circuit on each affected STS. This will clean up the stuck STSs. This issue
is resolved in Release 7.0.

The error message ('null') is invalid when, in a failed merge operation on two portless circuits, one circuit
loses its connection after the merge. You can see this if you merge two portless intranode UPSR circuits,
where one circuit has one source and two drops, and the other circuit has two sources and one drop.
Though the two drops of the first circuit might be aligned with the two drops of the second circuit, all of
them are inside one physical link (not a valid UPSR topology). To recover from this situation, open a
new CTC session. This will return the circuits to their status prior to the failed merge. This issue is
resolved in Release 7.0.

In a fiber cut scenario on the LINE-RX, with OSC and channels provisioned, transient LOS-P or LOS-O
alarms might be raised. This issue is resolved in Release 7.0.
Electrical IO Cards

The DS-1 line state of the portless ports (13, 14 and greater) does not match the corresponding DS-3 line
state when a DS3XM-12 conversion circuit is provisioned with the IS drop port state.
To see this, create a 1-way DS3XM-12 conversion circuit with the drop port state set to IS. Delete the
conversion circuit, leaving the IS port state. Note that the DS-1 line state will now be OOS by design. If
there is no circuit, DS-1 portless port lines will be placed in OOS state.
