Note CTC does not support the display of Cisco proprietary RPR circuit topologies.
Note CTC does not support provisioning or maintenance of IEEE RPR rings. You must use Cisco IOS.

11.13 Section and Path Trace
SONET J0 section and J1 and J2 path trace are repeated, fixed-length strings composed of 16 or 64
consecutive bytes. You can use the strings to monitor interruptions or changes to circuit traffic.
The OC192-XFP and MRC-12 cards support J0 section trace. Ta ble 11 -9 shows the ONS 15454 cards
that support J1 path trace. DS-1 and DS-3 cards can transmit and receive the J1 field, while the EC-1,
OC-3, OC-48 AS, and OC-192 can only receive the J1 bytes. Cards that are not listed in the table do not
support the J1 byte. The DS3XM-12 card supports J2 path trace for VT circuits.
