Troubleshooting Voice Trunks

NetVanta 7100 Administrator’s Guide	Maintaining and Troubleshooting

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 Physical Interfaces menu. The voice trunk interfaces are FXO and T1. The physical interface names are formatted <interface type> <slot/port> (e.g., t1 0/1).

1.Navigate to System > Physical Interfaces and check for green text in the Line Status of the trunk and T1 interfaces. If the text under Line Status is red, stop here and contact your network administrator for assistance. Otherwise, continue to the next step.

2.If the Line Status is OnHook or Up, your trunk line service is working properly. If the Line Status is Down, check the physical connection to your unit. If you suspect configuration or network issues, contact your NetVanta 7100 system administrator.
