Node Features
The System Description explains the relation of node features to the data services provided by the
node: basic and switched asynchronous services, predefined destination (PDD) connections,
multiplexed host interfaces, X.25/X.75 services, frame relay services, LAN interconnections,
interworking, and networking.
For BNS-2000 nodes, the SMDS Guide describes how to install, configure, and operate the
interfaces for nodes using SMDS. For SMDS, the Access Interface Module Reference is also
needed.
For BNS-2000 and BNS-2000 VCS nodes, the Session Maintenance Guide describes automatic
alternate routing and provides instructions on how to configure the node for this feature.
The node features are listed briefly, below, under three broad categories: main features,
operational features, and security features.
