¿µ¹®³»¿ë¿ä¾à THIS STANDARD SPECIFIES THE BASIC LOOK-AHEAD PROTOCOL FOR THE BROADBAND-INTEGRATED SERVICES DIGITAL NETWORK(B-ISDN) AT THE TB REFERENCE POINT OR COINCIDENT SB AND TB REFERENCE POINT(AS DEFINED IN STANDARD I.413[1]) FOR THE DIGITAL SUBSCRIBER SIGNALLING SYSTEM NO.2(DSS2) PROTOCOL.
THIS BASIC LOOK-AHEAD PROTOCOL ALLOWS PROVISION OF LOOK-AHEAD BETWEEN THE INCOMING SIDE OF A NETWORK AND THE OUTGOING SIDE OF THE SAME NETWORK. DECISIONS ON WHETHER TO USE BASIC LOOK-AHEAD PROTOCOL ARE MADE AT EACH INCOMING GATEWAY EXCHANGE. A MECHANISM EXISTS BETWEEN NETWORKS(E.G. AT THE TB REFERENCE POINT) TO ALLOW ONE NETWORK TO INDICATE TO ANOTHER NETWORK THAT BASIC LOOK-AHEAD IS REQUIRED.
