EVENT MANAGEMENT
157: ZEXP-EVT-CSS-FRAME-ERR
Probable Cause
An invalid frame was received. It is normal for this event
to occur during a path switch. Generally, the EXPAND software
recovers from this event automatically; if it cannot recover, it
brings down the line.
Recommended Action
If this event did not occur during a path switch, note the values
of ZEXP-TKN-FRAME-ERR, ZEXP-TKN-FRAME-A-C, and ZEXP-TKN-FRAME-T-S
and contact your Tandem representative.
