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.
