ENCAP-MISMATCH-P
Default Severity: Critical (CR), Service-Affecting (SA)
Logical Object: STSTRM
The Encapsulation C2 Byte Mismatch Path alarm applies to ML-Series Ethernet cards or the CE-1000 card.
It occurs when the first three following conditions are met and one of the last two is false:
• The received C2 byte is not 0x00 (unequipped).
• The received C2 byte is not a PDI value.
• The received C2 does not match the expected C2.
• The expected C2 byte is not 0x01 (equipped unspecified).
• The received C2 byte is not 0x01 (equipped unspecified).
For an ENCAP-MISMATCH-P to be raised, there is a mismatch between the received and expected C2 byte,
with either the expected byte or received byte value being 0x01.
For example, an ENCAP-MISMATCH-P alarm is raised if a circuit created between two ML-Series or two
CE-1000 cards has generic framing procedure (GFP) framing provisioned on one end and HDLC framing
