Configuring the T1 Network
5-80 Access Manager 2000 User Manual
An interval is a 15-minute (900-second) segment of time, and there
are 96 intervals in 24 hours. An Interval Count is defined as the
time window within which you want to count trouble seconds. It
includes the number of intervals you specify plus the current
interval you’re in.
A Threshold is the maximum number of trouble seconds allowable
in an Interval Count.
It takes the length of the configured Interval Count to clear an
alarm.
These are the default values:
If the interval count is 0 , then:
• only the current interval is used to determine if the Threshold is
exceeded, and
• the alarm is cleared at the end of the current interval.
To disable alarm reporting during excessive BPV, ES, or UAS errors, set
their threshold values to
0 .
3. To report turn on the alarm relay when a loopback toward the
NET is either activated or cleared
, set the NET Loopback
Alarm Relay option to YES (default).
The alarm relay is a 3-pin terminal strip, surrounded by bright
orange plastic, located in the middle of every CIM faceplate. It can
be connected to an external device---such as a light, bell, or
buzzer---to provide a noticeable alarm when a loopback toward the
net is activated or cleared.
4. Decide how long an alarm condition must persist before the CSU
reports it to Access Manager.
