1. Terminology and Definitions

   The following terms are used in this document:

   Carrier Termination (CT) is an interface for the
   capacity provided over the air by a single carrier. It
   is typically defined by its transmitting and receiving
   frequencies.

   Radio Link Terminal (RLT) is an interface providing
   packet capacity and/or TDM capacity to the associated
   Ethernet and/or TDM interfaces in a node and used for
   setting up a transport service over a
   microwave/millimeter wave link.

   The following acronyms are used in this document:
   ACM  Adaptive Coding Modulation
   ATPC Automatic Transmit Power Control
   CM   Coding Modulation
   CT   Carrier Termination
   RLT  Radio Link Terminal
   RTPC Remote Transmit Power Control
   XPIC Cross Polarization Interference Cancellation

2. Introduction

   This document defines a YANG data model for management
   and control of the radio link interface(s) and the
   relationship to packet (typically Ethernet) and/or TDM
   interfaces in a microwave/millimeter wave node. The date
   model includes configuration and state data.

   The design of the data model follows the framework for
   management and control of microwave and millimeter wave
   interface parameters defined in [mw-fmwk]. This
   framework identifies the need and the scope of the YANG
   data model, the use cases and requirements that the
   model needs to support. Moreover, it provides a detailed
   gap analysis to identify the missing parameters and
   functionalities of the existing and established models
   to support the specified use cases and requirements, and
   based on that recommends how the gaps should be filled
   with the development of the new model.

   According to the conclusion of the gap analysis, the
   structure of the data model is based on the structure
   defined in [I-D.ahlberg-ccamp-microwave-radio-link] and
   it augments RFC 7223 to align with the same structure
   for management of the packet interfaces. More
   specifically, the model will include interface layering
   to manage the capacity provided by a radio link terminal
   for the associated Ethernet and TDM interfaces, using
   the principles for interface layering described in RFC
   7223 as a basis.

   The designed YANG data model uses the IETF: Radio Link
   Model [I-D.ahlberg-ccamp-microwave-radio-link] and the
   ONF: Microwave Modeling [ONF-model] as the basis for the
   definition of the detailed leafs/parameters, and
   proposes new ones to cover identified gaps which are
   analyzed in [mw-fmwk].

5. Security Considerations

   The YANG module defined in this memo is designed to be
   accessed via the NETCONF protocol [RFC6241].  The lowest
   NETCONF layer is the secure transport layer and the
   mandatory-to-implement secure transport is SSH
   [RFC6242].  The NETCONF access control model [RFC6536]
   provides the means to restrict access for particular
   NETCONF users to a pre-configured subset of all
   available NETCONF protocol operations and content.

   There are a number of data nodes defined in the YANG
   module which are writable/creatable/deletable (i.e.,
   config true, which is the default).  These data nodes
   may be considered sensitive or vulnerable in some
   network environments. Write operations (e.g., <edit-
   config>) to these data nodes without proper protection
   can have a negative effect on network operations.

   The security considerations of [RFC7223] also apply to
   this document.

6. IANA Considerations

   TBD.
