OTGR Section 11.1: Generic Operations Interface - Non-OSI Communications Architecture
Document Number TR-TSY-000827
Issue Number 01
Issue Date Nov 1988
ABSTRACT: This Technical Reference (TR) describes the view of Telcordia on generic communications requirements for small Network Elements (NEs)
when a non-OSI (Open Systems Interconnection) communications architecture is implemented.
In this model, the Application interfaces directly to the services provided by either the Network Layer or Data Link Layer. The
selected protocol for the Network Layer of the OSI model is X.25, and the requirements for Physical, Data Link, and Network Layers of
the protocol are listed. In addition, two languages are proposed for Application messages.
