Configuring Additional Features on the
Cisco VGD 1T3 Voice Gateway
The information in this chapter applies to the Cisco VGD 1T3 voice gateway. This chapter continues
where the
“Basic Configuration Using the Command-Line Interface” chapter ends. After you have
commissioned your Cisco VGD 1T3 voice gateway, you might want to configure other features that
include serial interface support, T1 channel groups, and signaling.
Proceed to the following sections:
• Configuring Synchronous Serial Interfaces for WAN Support, page 67
•
Configuring ISDN NFAS on Channelized T1 PRI Groups, page 69
• Configuring Alarms, page 70
•
Saving Configuration Changes, page 71
• Where to Go Next, page 72
Configuring Synchronous Serial Interfaces for WAN Support
Configure the synchronous serial interfaces on the motherboard to connect to a WAN through a CSU
or DSU.
This section describes how to enable the serial interface, specify IP routing, and set up external clock
timing on a DCE or DTE interface. To use a port as a DTE interface, you need only connect a DTE
adapter cable to the port. When the system detects the DTE mode cable, it automatically uses the external
timing signal. To use a port in DCE mode, you must connect a DCE interface cable and set the clock
speed with the clock rate configuration command. You must also set the clock rate to perform a loopback
test.
