Carrier Access 1750 Benutzerhandbuch

The failure recovery process is a logical sequence of events to restore connectivity. 
With monitoring and corrective action at each step, the process includes:

Providing power to the Broadmore 1750 and control station

Establishing connectivity between the Broadmore 1750 and control station

Loading the Broadmore 1750 configuration

Establishing ATM connectivity

Establishing individual circuit connectivity 

Alarms are designed into the Broadmore 1750 to provide the initial indication of a 
communications problem and to help isolate the problem. For example, a major alarm 
from a SAM identifies the specific module that will focus response efforts. The 
following flowchart approach to troubleshooting is based upon the initial alarm 
indication. The alarm response is a three-step process:

1. Troubleshoot to isolate the cause.

2. Complete corrective action to eliminate the alarm condition.

3. Return system to full operation and document the events.

Alarms are designed as real-time alerts. Thus, elimination of the alarm condition will 
automatically reset the associated alarm.

The top-level troubleshooting flowchart is shown on the below. LED indicators are the 
basis for entry into the flowchart, which will lead to the most likely problem(s) and 
recommended solution(s). The control system alarm indication can also be used as an 
entry point. In either case, use of this flowchart provides a logical approach to 
troubleshooting in the event that a problem is encountered.
