BCM50 Administration Guide
Viewing Performance History information
The Performance History tab displays the performance information over 15-minute intervals
collected in the past 24 hours. The performance information collected includes the number of
errored seconds, severely errored seconds, and unavailable seconds over each 15-minute interval.
1 On the navigation tree, click Administration, Telephony Metrics, Trunk Module Metrics.
2 Click the Performance History tab to view metrics information.
Viewing D-Channel information
This tab displays trunk module metrics for the D-channel. D-channel metrics display when a BRI
trunk module is configured on the system.
1 On the navigation tree, click Administration, Telephony Metrics, Trunk Module Metrics.
2 Click the D-channel tab to view metrics information.
Disabling or enabling a B channel setting
If you need to isolate a problem, you may need to turn off individual port channels, rather than the
entire module.
To disable or enable a B channel setting
1 On the navigation tree, click Administration > Telephony Metrics > Trunk Module
Metrics.
The window displays Expansion 1 or Expansion 2.
2 Click heading of the bus you want to view. For example, click Expansion 1.
3 Click the tab in the lower menu marked B-Channels.
4 Click the B channel you want to enable or disable (B1 or B2).
5 Then select Enable or Disable.
If you are disabling the channel, you are prompted by a dialog box to confirm your action. The
State field indicates the mode of operation for the port. If the port is enabled, this field is blank
unless a device is physically connected.
Provisioning a PRI B-channel
When you purchase PRI from your service provider, you can request the number of B-channels
that are allocated for you to use. For example, you may want to use only 12 B-channels. If you do
not have all of the PRI B channels, disable all the B-channels that you do not need.
Nortel recommends that the number of lines that are deprovisioned on a DTM (configured as PRI)
be the same as the number of B-channels that are disabled. For example, if the DTM is on
Expansion 1, when B-channels 13-23 are disabled, you should deprovision lines 77 to 87.
