The CE-100T-8 card supports GFP-F null mode. GFP-F CMFs are counted and discarded.
The CE-100T-8 card is interoperable with the ML-100T-8 card and several other ONS Ethernet cards.
For specific details on ONS Ethernet card interoperability, refer to the “POS on ONS Ethernet Cards”
chapter of the Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card Software Feature and
Configuration Guide.
CE-100T-8 Loopback, J1 Path Trace, and SONET Alarms
The CE-100T-8 card supports terminal and facility loopbacks when in the Out of Service, Maintenance
state (OOS, MT). It also reports SONET alarms and transmits and monitors the J1 Path Trace byte in the
same manner as OC-N cards. Support for path termination functions includes:
• H1 and H2 concatenation indication
• C2 signal label
• Bit interleaved parity 3 (BIP-3) generation
• G1 path status indication
• C2 path signal label read/write
• Path level alarms and conditions, including loss of pointer, unequipped, payload mismatch, alarm
indication signal (AIS) detection, and remote defect indication (RDI)
• J1 path trace for high order paths
• J2 path trace for low order paths
• J2 path trace for low order VCAT circuits at the member level
• Extended signal label for the low order paths
