Provisioning SONET/SDH Circuits
CTC provisions and edits STS/STM level circuits for the two virtual SONET/SDH ports of the
ML-Series card in the same manner as it provisions other ONS 15454 SONET/SDH OC-N cards. The
ONS 15454 ML-Series card supports both contiguous concatenation (CCAT) and virtual concatenation
(VCAT) circuits.
For step-by-step instructions to configure an ML-Series card SONET CCAT or VCAT circuit, refer to
the “Create Circuits and VT Tunnels” chapter of the Cisco ONS 15454 Procedure Guide. For
step-by-step instructions to configure an ML-Series card SDH CCAT or VCAT circuit, refer to the
“Create Circuits and Tunnels” chapter of the Cisco ONS 15454 SDH Procedure Guide. For more
general information on VCAT circuits, refer to the “Circuits and Tunnels” chapter of the Cisco ONS
15454 Reference Manual or the Cisco ONS 15454 SDH Reference Manual.
J1 Path Trace
The J1 Path Trace is a repeated, fixed-length string comprised of 64 consecutive J1 bytes. You can use
the string to monitor interruptions or changes to SONET/SDH circuit traffic. For information on J1 Path
Trace, refer to the Cisco ONS 15454 Reference Manual or the Cisco ONS 15454 SDH Reference
Manual.
