DESCRIPTION
 The  frame_relay node type performs encapsulation, de-encapsulation, and multiplexing of packets using the frame relay protocol. It supports up to 1024 DLCIs. The LMI protocol is handled by a separate node type (see ng_lmi(4)).  The  downstream hook should be connected to the synchronous line, i.e., the switch. Then hooks  dlci0,  dlci1, through  dlci1023 are available to connect to each of the DLCI channels.
