The primary function of the NetWare Link/X.25 Packet layer is to multiplex the single interface onto multiple channels called virtual circuits.
The Packet layer performs the following functions:
The Packet layer defines the interface that gives users (or network applications) access to a packet-switched network. It is responsible for establishing network connections and providing communications paths between end systems. It uses the statistical time-division multiplexing (STDM) technique to multiplex simultaneous connections over a single physical link. The Packet layer is responsible for establishing, maintaining, and disconnecting end-to-end logical calls or connections.
