Configuration Screens 4-17
# of Channels
Sets the number of channels to be passed through to the T1 DTE, from 1 through 24.
Channel Allocation
This display field indicates network channel assignments with Channel 1 on the
left and Channel 24 on the right. Channels assigned to a port are identified with
port number 1. Channels assigned to the T1 DTE are marked as D. Non-assigned
idle channels are marked with a hyphen (-). Remote communication channels are
marked with an R. When channels are assigned to a port in the ALTERNATE
assignment mode (see Port Parameters on page 4 -19), each data channel is
followed by an idle channel that is not assignable for other ports and is marked
with an x.
Alarm
Parameters
The Alarm Parameters screen (Figure 4-10) allows reviewing and setting
alarm-related thresholds for the selected element. These thresholds are the
minimum acceptable performance levels. To modify the parameters, highlight the
desired statistic, type in the new value (from 0 to 900) and press Enter. If this
value is later surpassed, an alarm indication appears. A field set to zero causes the
element not to alarm on that statistic.
Errored Seconds
A one-second period in which at least one logic error occurred.
Severely Errored Seconds
A one-second period in which at least 320 CRC errors or 1 OOF (out-of -frame)
event occurred.
Loss of Signal Seconds
A one-second period in which the T1 received signal is interrupted.
Unavailable Seconds
A one-second period in which consecutive severely errored seconds cause an
unavailable state.
