DATALINK function PRM RCVR is ON. The far-
end PRM results are also available in the AUTO
LLB and T1 LLB modes.
In the SMARTNIU mode, the NIU/Performance

can not be displayed in the RESULTS display. Only

percentage values representing the overall perfor-
mance of the circuit in each direction.

The retrieved data is only available as a Smart NIU
Results printout. The T1 circuit is monitored in both
directions, and the results are stored as either AZ (CO
to NIU) or ZA (Customer to NIU). The statistics are
recorded and identified as follows:
CVL — Line Coding Violations is a count of
bipolar violations that are not part of a B8ZS
sequence.
ESL — Line Errored Seconds is a count of
seconds in which at least one CVL has occurred.
