ABSTRACT:
In a PPP terminating equipment connected with a switch fabric and terminating PPP link, the PPP terminating equipment has an LCP echo requirement detecting section detecting whether or not a received packet is the LCP echo requirement packet, and an LCP echo response producing section producing a response packet to the LCP echo requirement by rewriting the LCP header of the received LCP echo requirement packet. The PPP terminating equipment thereby produces and returns the response packet to the LCP echo requirement.
