These parameters are defined as per TIA-547A. Errored seconds are enhanced to

include control slip (CS) events. Only near-end performance data is recorded.

The internal CSU continuously monitors the received signal and detects four types

of transmission defects:

• any active carrier failure alarms (CFA) (loss of signal LOS, out of frame OOF,

alarm indication signal AIS, remote alarm indication RAI)

• the number of bipolar violations that occurred in the last minute

• any defects (loss of signal LOS, out of frame OOF, alarm indication signal AIS)

that occurred in the last minute

• the number of milliseconds of short term alarms (loss of signal LOS, out of

frame OOF, alarm indication signal AIS, remote alarm indication RAI) in the

last minute. A short term alarm is declared when the detected defectspersist for

tens of milliseconds.

A carrier failure alarm (CFA) is a duration of carrier system outage. CFA types

reported can be mapped to CFAs defined in TIA-547A and TR62411 as follows:

The criteria for declaring and clearing the alarms is selectable to meet those in TIA-

547A or TR64211.

Enable the internal CSU

Use the following procedure to enable the internal CSU to gather performance

statistics for your T1 lines or PRI with public interface.

1. Choose Resources, Media Bay Modules.

The window displays Bus 02 through to 08.

2. Choose the appropriate bus. For example, Bus 02.

3. Choose Modules on Bus.

The modules on this bus are displayed.

4. Choose the appropriate module. For example, Module 1.

5. ClickontheT1 Parameters heading.

6. In the Internal CSU box, select On from the drop-down menu.

The module is temporarily disabled while the internal CSU is enabled.
