T1 Zero Suppression Determines whether ones density insertion is activated after 15 zeros. This
parameter is ignored if the Coding parameter is set to “B8ZS.”
Values: Disable, Enable
Default: Disable
T1 Mode As a T1, the unit will operate in either long-haul or short-haul mode.
Values: Short-Haul, Long-Haul
Default: Short-Haul
T1 Line Build Out Sets the transmit Line Build Out (LBO) for the CBR interface.

Error Status and Alarm Thresholds Table
The unit can be programmed to generate an alarm condition based on a
specific level of performance degradation. The CBR screen presents a table
that provides current error status and alarm threshold information.
Acceptable alarm thresholds are set for periods of 15 minutes (900 seconds)
and sampled every second. The error types listed in the following paragraphs
can be preset to a value between 0 and 900 seconds. Setting a field to “0”
(zero) disables the alarm on that statistic. To effectively disable alarm
reporting, set all fields to “0” (zero).
The 15-minute time frame is not based on the TR 54016 or T1.403 interval
boundaries, but is a time window based on the accumulated counts over the
previous fifteen 1-minute intervals. In all cases, if the number of actual
network errored seconds in the previous 15 minutes reaches the preset
threshold for the specified error type, an alarm condition is declared.
The four columns of the status table are as follows:
•
Status: Displays the current status of the CBR port.
•
Alarm: Displays the alarm value of the network port. The unit declares an
alarm as soon as the count exceeds the threshold set.
•
Count: Displays the number of events or occurrences of this statistic that
have been detected.
•
Threshold: Displays a read/write field that can be set to a desirable
threshold.
The table provides error status and alarm threshold information for the
following error parameters:
