The
Performance Data Definitions
and Figure 21, describe each line, path, and far-end
performance parameter and explain using reverse video
to indicate incomplete or invalid data registers.
CIRCUIT ID: xxxxxxx
Line Related (Near End only):
ES-L
SES-L
LOSS-L
CV-L
Path Related (Near End):
ES-P
SES-P
UAS-P
CV-P
NOTE: Reverse video indicates invalid data due to a terminal restart (or power
cycle), a data register reset, or a system date or time change.

CIRCUIT ID: xxxxxxx
Path Related (Near End continued):
SAS-P
SEFS-P
AISS-P
Path Related (Far End):
ES-P
SES-P
UAS-P
CV-P
NOTE: Under an UAS-P condition, ES-P, SES-P, CV-P, SAS-P, SEFS-P and
AISS-P counts are inhibited. Under a SES-L or SES-P condition, the
respective CV-L or CV-P count is inhibited.
NOTE: Parity errors are P-bit parity errors for M13 framing and CP-bit parity
errors for C-bit framing.
