VTSOCI
....................................................................................................................................................................................................................................
The OT has detected a Virtual Time Slot Open Connection Indication on an associated
VTS. This condition is raised when the downstream 11DPE12/11DPE12E OT receives an
APS/PCC message indicating an OCI from the upstream OT. The VTSOCI alarm is raised
at the downstream OT on the Virtual Time Slot [

WKSWBK
WKSWBK (Automatic switch to working)
WKSWBK indicates an automatic protection switch from the "protection side" to the
"working side". As a result, the working side becomes the active side. This can occur
when a fault is detected on the protection side, or when the user provisions the protection
side to Admin Down. It applies to all protection schemes (Y-cable, OPS, ESNCP) when
the protection group is non-revertive. (Y-cable can be provisioned to either revertive or
non-revertive. OPS and ESNCP are always non-revertive.)
