The VC-4 tab allows you to view and update OC192/STM64 XFR-based card VC-4 information.
Port No. Port number.
LBC-HIGH Laser bias current maximum.
LBC-LOW Laser bias current minimum.
OPT-HIGH Optical power transmitted maximum.
OPT-LOW Optical power transmitted minimum.
OPR-HIGH Optical power received maximum.
OPR-LOW Optical power received minimum.
Set OPR Setting the optical power received (OPR) establishes the received power level as 100 percent. If the
receiverpower decreases, then the OPR percentage decreases to reflect the loss in receiver power.For
example, if the receiver power decreases 3 dBm, the OPR decreases 50 percent.

VC-4 Config
Displays the VC-4 number and the intermediate path protection monitoring (IPPM) status.
Path Thresh 15 Min, Path Thresh 1 Day
Port Number The VC-4 port number.
EB-HP Errored blocks–higher order path.
ES-HP Errored seconds–higher order path.
SES-HP Severely errored seconds–higher order path.
UAS-HP Unavailable seconds–higher order path.

PPJC-Pdet Positive pointer justification count, STS path detected.
NPJC-Pdet Negative pointer justification count, STS path detected.
PPJC-Pgen Positive pointer justification count, STS path generated.
NPJC-Pgen Negative pointer justification count, STS path generated.
PJCS-Pdet Positive pointer justification count, STS path detected.
PJCS-Pgen Positive pointer justification count, STS path generated.
PJC-Diff The sum of the absolute values of differences between positive transmitted and received, and negative
transmitted and received. The important metric on pointer justification is not the exact counts, but how
many were absorbed.
