Hardware
DDTS # CSCec33248
Pulling the active XCVXL card might result in a traffic outage lasting for greater than 2 seconds. It is
possible to see this approximately 1 out of every 7 active XCVXL card pulls. Excessive traffic outage
from this issue will not occur after a software-induced XCVXL side switch. In this case, you can expect
a traffic hit of less than 60 ms, and traffic will resume normally.

DDTS # CSCdw92634
SDH DS3-i and E3 electrical cards only support a VC4 J1 trace string setting for all VC4s together. You
cannot set the J1 byte for individual VC4s. This issue is a limitation of hardware.

Note
VC3 J1 strings can be set individually, but the optical cards cannot monitor the VC3 J1 string.
DDTS # CSCdy00622
Very rarely, an Equipment Failure Alarm can occur on an externally timed TCC+ or TCC-I card after a
reset. If this occurs, BITS will be displayed as good for one TCC, but bad for the other. If the issue occurs
on the standby TCC, a second reset could clear the problem. If the issue occurs on the active TCC, the
card must be replaced. This issue is closed, as it does not occur with TCC2, and is otherwise very rare.
