Foreword
This Group Specification (GS) has been produced by ETSI Industry Specification (ISG) Open Radio equipment
Interface (ORI).
The present document is part 1 of a multi-part deliverable covering the ORI Interface Specification, as identified below:
Part 1: "Low Layers (Release 1)";
Part 2: "Control and Management (Release 1)".

1 Scope
The present document defines low layer protocols aspects of the Open Radio equipment Interface (ORI). Low layer
protocols are those terminating the ORI Link (a bi-directional interface in-between two directly-connected ORI ports,
on two ORI nodes).
The Layer 1/2 protocols of CPRI Specification [1] have been used as a baseline for which further requirements for
protocols up to and including the Layer 2 have been defined.
See the associated specification "Requirements for Open Radio equipment Interface" [2] for more information on how
the Low Layer protocols relate to other aspects of the ORI interface.
