Display Format
The 24-hour register contents are displayed as shown in Figure 7-7. The 24-hour
period is divided into 15-minute intervals. The top line of the report gives the
register type (User, Telco, Aux, FDL Telco, or FDL User), parameter type,
system name, and time. The report header gives:
•
•
Error counts for the total of valid intervals over the last 24-hour period and the
current interval for all registers except BPV and ESF.
The body of the report gives error counts for the 15-minute intervals in a matrix,
with intervals 1 (most recent) through 8 on the line beginning 01, etc.
Errors continue to be counted while a diagnostic is in progress (i.e., the
Access-T is in loopback or is transmitting a test signal). All registers are
cleared at power-up or when the framing mode is changed (from D4 to
ESF or vice versa). User and Aux statistics are also cleared by the Clear
Registers command (
chapter. Telco statistics can be cleared by a command from the network
(i.e., by the telco).

Severely Errored Seconds (SES)—maximum value of 65,535.
Unavailable Seconds (UAS)—maximum value of 65,535.
Bursty Errored Seconds (BES)—maximum value of 65,535.

able via the FDL when supported by far-end equipment).

ESF Errors—maximum value of 65,535; User and Aux.
The number of seconds (maximum 900) in the current incomplete
interval.
The number of valid complete intervals (maximum of 96; reset at
power-up or when register is cleared).
Note: BPV and ESF errors for the 24-hour and current counts
are displayed only in their respective reports.
