2.7.46 DS3-MISM
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SDH Logical Object: DS3
The DS-3 Frame Format Mismatch condition indicates that a line type format mismatch on a signal
received on the DS-3 port of a 15310-MA SDH CTX, E1-21/DS3-E3-3, or E1-63/DS3-E3-3 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 DS-3 port is set to C Bit and the incoming signal line type is detected
as M13, then the port reports a DS3-MISM condition.
Clear the DS3-MISM Condition
Step 1 In node view, double-click the ONS 15310-MA SDH to display the card view.
Step 2 Click the Provisioning > DS3 > Line tabs.
Step 3 For the row on the appropriate port, verify that the Line Type column is set to match the expected
incoming signal (C bit or M13).
Step 4 If the Line Type field does not match the expected incoming signal, select the correct Line Type in the
drop-down list.
Step 5 Click Apply.
