network port is always used in frame relay protocol configurations.
The network port terminates the user end of the frame relay UNI
interface. The Express 5210 supports three standard PVC signaling
formats: LMI (gang of four), ANSI T1.617-D (Annex D), and ITU
Q.933-A (Annex A). The selected signaling format is used to poll
the network end of the UNI interface and retrieve virtual circuit
information. Optionally, 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.
