1.2.3.2 Highlights
 Access density and processing capability
RSR20-18 comes with eight SIC slots, which supports up to two non-channelized E1,
eight ISDN U or S/T interfaces, three sync serial interfaces, three 3G interface cards,
four Layer 2 switching Ethernet interfaces, and 64 asyn serial interfaces to provide the
high-density remote OA solution. Moreover, RSR20-14 comes with one NMX slot that
supports 24 Layer 2/3 switching Ethernet interfaces. The E1 interface complies with
ITU-T G.703; the ISDN U interface complies with ITU-T G.961 ANSI T1.601, and the
ISDN S/T interface complies with ITU-T I.430. The sync serial port can connect the
networks such as DDN, frame relay, and X.25. These make the router suitable as an
access router for large/medium-sized branches.
