This chapter explains how to diagnose and handle DMT-2 modem events generated by the Cisco 6100 Series system. The following information is presented for each of the events:
If none of the actions presented for the event are successful, contact the Cisco Technical Assistance Center (TAC) for additional support.
Table 5-1 lists DMT-2 modem events and their IDs, definition, severity, and description. A detailed explanation of these events and corrective actions required (if any) is located in subsections in this chapter.

The following description appears in the ViewRunner for Windows Event History View dialog box or the ViewRunner for HP OpenView Error Events Browser:
CPE modem unable to support provisioned latency path (Interleaved/Fast)The subscriber has been provisioned to use of a latency path which is not supported by the module or the CPE. Because the latency path is not supported, no data will be passed once the session is established.
Re-provision the subscriber. By default, re-provision back to latency.
