2.7.77 DS3-MISM
The DS-3 Frame Format Mismatch condition indicates a frame format mismatch on a signal transiting
the ONS 15454 DS3XM-6, DS3XM-12, or DS3/EC1-48 card. The condition occurs when the
provisioned line type and incoming signal frame format type do no match. For example, if the line type
for a DS3XM-6 card is set to C Bit and the incoming signal frame format is detected as M13, then the
ONS 15454 reports a DS3-MISM condition.
