Troubleshooting Voice Trunks

Voice trunks are the telephone lines delivered to the carrier in digital or analog format (e.g., T1 or trunk
FXO lines). Trunk lines connect the NetVanta 7100 to the outside telephone network. The incoming lines
are linked to physical interfaces on the system. These interfaces control which resources are used for
outbound calls. This section covers the most common issues that prevent users from placing outbound
calls.

Checking the Port Status

Check the status of the telephone lines under the
FXO and T1. The physical interface names are formatted <interface type> <slot/port> (e.g., t1 0/1).
