Operation: displays the current operaion mode (T1 or E1), line build out, channel rate and frame encoding.
Line: Link status – connected or disconnected
# of 15-min intervals: count of 15 minute intervals since the statistics were last cleared.
# of current seconds: count of seconds since the beginning of the current 15 minute sampling interval
ES Errored Seconds – seconds in which a single CRC, Framing or Out of Frame error occurred
BES Bursty Errored Seconds – seconds with more than one but less than 320 CRC, Framing or Out of
Frame errors.
SES Severely Errored Seconds – seconds with 320 or more CRC, Framing or Out of Frame errors.
UAS Unavailable Seconds – blocks of severely errored seconds, each block starts at the first 10 contigous
SES, ends when 10 non-SES received.
SLIPS Count of slip events - when data is received faster than it can be read from receive buffer, a frame is
dropped to clear the buffer.
LOFC Loss of Frame Count – count of times the unit cannot synchronize on a framing pattern in the
received signal.
SEFS Severely Errored Framing Seconds – seconds with 320 or more frame synchronization errors.
LES Line Errored Seconds – count of seconds with more than one line code violation (LCV).
