Date created:   7-15-2003
Increment Type: TDM

Title: TDM: MLC failures during Protection Switching Activities
----------------------------------------------------------------------
Following is a list of issues addressed in this Increment. See below
for more details.
1. MLC failures during Optical Protection Switching Activities
----------------------------------------------------------------------
1. MLC failures during Optical Protection Switching Activities
* Description: Primary optic protection switching may cause the 
UE9000 to momentarily fail Multiple-circuit Line Card (MLC) circuit 
packs.
* Pre-Increment Impact and work-around: Tests have shown that action
is not required by the customer to restore service to the impacted 
lines. However, under adverse conditions (such as several UE9000 shelves 
reporting multiple MLC failures) a more controlled recovery may speed
overall system return to service. This can be accomplished by taking
all the UE9000 shelves in trouble offline, and allowing each to recover
in a serial fashion.
