CE-MR-6 Ethernet Card
G1 path status indication
C2 path signal label read/write
Path level alarms and conditions, including loss of pointer (LOP), unequipped, payload mismatch,
alarm indication signal (AIS) detection, and remote defect indication (RDI)
J1 path trace for high-order CCAT paths
J2 path trace for low-order VCAT circuits at the member level
Extended signal label for the low-order paths
Terminal and Facility Loopback on LCAS Circuits In Split Fibre Routing
The following section lists guidelines to follow when the CE-MR-6 card includes a split fiber routing in
a terminal and facility loopback on SW-LCAS circuits:
Note
Make sure that you follow the guidelines and tasks listed in the following section. Not doing so will
result in traffic going down on members passing through optical spans that do not have loopbacks.
SW-LCAS circuit members must have J1 path trace set to manual.
Transmit and receive traces must be unique.
SW-LCAS circuits on CE-MR-6 must allow our of group (OOG) members on Trace Identifier
Mismatch - Path (TIM-P).
For members on split fiber routes, facility loopback must select the AIS option in CTC.
Traffic hit is expected when loopback is applied. This is due to asynchronous detection of VCAT
defects and TIM-P detection on the other end of the circuit. This is acceptable since loopbacks are
intrusive and affect traffic.
However, place members of an HW-LCAS circuit traversing an optical interface under maintenance in
OOS,OOG (locked, outOfGroup) state before applying terminal/facility loopbacks.
