Possible Causes
Three possible causes exist.
1. An E1 card is inserted in a slot where a T1 card WAS present (or vice-versa), resulting in a
configuration mismatch.
2. When at least the minimum number of DSPs failed to download - currently the threshold is fixed
at 5.
3. When the backcard type does not match the front card type - if the front card is of type T1 (E!)
and the backcard type is E1 (T1).
VISM Going to Standby : Configuration Mismatch Between ASC and VISMV
When a minimum number of DSPs failed to download, the "dsplog" on the PXM shows the following:
01/01/1970-00:02:10 05 tDspmDl VISM-6-9193
DSPM task errors : 6 DSPs failed to download
If the number of DSPs (6 in the above case) is greater than 5, then, the card will fail to come up ACTIVE.
