Caveats
DDTS # CSCdv40700
In either a DS1 or DS3 1:N protection group, deleting a standby working card from the provisioned
protection group can cause a traffic hit of greater than 60 ms. Do not delete any working cards from the
protection group when the protect card is active. Instead, switch traffic away from the protect card, then
delete the working card from the protection group. This issue will be resolved in a future release.

Performing cross connect card switches repeatedly might cause a signal degrade condition on the lines
or paths that can trigger switching on these lines or paths. If you must perform repeated cross connect
card switches, lock out the corresponding span path protection configuration, BLSR, or 1+1) first, or,
wait 60 seconds between cross connect switches to avoid causing signal degrade crossings for bit error
rate thresholds up to 10E-9.

LOS Behavior
When an OC-N card is seeing LOS and the problem is resolved (for example, the pulled fiber is
reinserted) the LOS will normally clear quickly, and any other errors seen on the signal will be raised.
However, in the special case where the restored signal is unframed, the LOS will remain raised (that is,
the LOS will not be replaced by an LOF). This is standard SONET behavior per Telcordia GR-253
R6-57, Method 1, where to clear LOS the signal must also contain valid framing alignment patterns.
