Configuring the Network Port

NETWORK PORT

Access the Network Port menus by selecting Network Port from the Configuration menu. See the menu tree in Figure 7-1. The network port is always used in frame relay protocol configura- tions. The network port terminates the user end of the frame relay UNI interface. The FSU supports three standard PVC signaling formats: LMI, ANSI T1.617-D, and ITU Q.933-A. The selected signaling format is used to poll the network end of the UNI interface and retrieve virtual circuit information. Option- ally the polling process can be disabled.

User data is encapsulated into standard frame relay formatted frames using two methods. FRF 3.1 IA procedures are used for IP and LLC2 protocols while a proprietary method is used for transparent protocol mode. Virtual circuit sharing is allowed for both methods.

Configure the Network Port before the DTE Ports. Selections made will affect the choices available for the DTE ports.

Connection

Connection is made through the internal DDS 56/64 DSU (if installed). If this option is not installed, use an external DDS or fractional T1 (up to 512 kbps) DSU.
