Implementation Notes

This chapter provides information about the Bay Networks implementation of

SMDS. Speciﬁcally, it contains information about the router’s DXI protocol

requirements and the Local Management Interface protocol. This chapter also

supplies details on the use of SMDS group and individual addresses for multinet

and multigroup conﬁgurations.

To implement high-speed SMDS, you need a Bay Networks router and an SMDS

DSU/CSU that provides DS1- or DS3-based access to the switched SMDS

network. A synchronous or high-speed serial interface (HSSI) physically connects

the router and the DSU/CSU (Figure

2-1).

The router also supports low-speed SMDS through the SNI and DXI

speciﬁcations standardized by the SMDS Interest Group. If you are running

low-speed SMDS, you can extend the DXI to the SMDS network, thereby

eliminating the need for a special SMDS DSU/CSU. Any synchronous interface,

including MCT1 or MCE1 link modules, physically connects the router and the

network (Figure

2-2).
