Unit Loads

Check the Trunks

Troubleshoot the trunks that are connected to the control unit. See Chapter 5, “Central Office Problems.”

Check the Central Office

If the error logs indicate the central office as the source of the problem, and you have resolved all other possible causes, notify the customer that they should call the central office and ask the central office to check the problem at their end (see Chapter 5, “Central Office Problems”):

If the problem is in the central office, wait for the CO to fix it, Then duplicate the problem conditions to ensure that the problem is really fixed.

If the problem persists, get the customer to again call the central office with the problem.

If they indicate that the problem is not in the central office, escalate the problem as described below.

Escalating the Problem

Escalate any unresolved problems to your technical support organization. See “System Inventory” in Chapter 2, which explains how to access the System Inventory screen, This screen contains information (such as the hardware vintage, software vintage, and ROM ID for each module) that your technical support organization may request.
