Clear the HP-DEG Condition

HP-DEG clears when the BER level falls to one-tenth of the threshold level that triggered the alarm.

HP-ENCAP-MISMATCH
Default Severity: Critical (CR), Service-Affecting (SA)
Logical Object: VCTRM-HP
The High-Order Path Encapsulation C2 Byte Mismatch alarm applies to ML-Series Ethernet cards. 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).
(This is in contrast to LP-PLM, which must meet all five criteria.) For an HP-ENCAP-MISMATCH 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.
An example situation that would raise an HP-ENCAP-MISMATCH alarm is if a circuit created between two
ML-Series cards has GFP framing provisioned on one end and high-level data link control (HDLC) framing
with LEX encapsulation provisioned on the other. The GFP framing card transmits and expects a C2 byte of
0x1B, while the HDLC framing card transmits and expects a C2 byte of 0x01.
A mismatch between the transmit and receive cards on any of the following parameters can cause the alarm:
• Mode (HDLC, GFP-F)
• Encapsulation (LEX, HDLC, PPP)
• CRC size (16 or 32)
• Scrambling state (on or off)
