1. 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 Time-Division Multiplexing (TDM) interfaces in a microwave/millimeter wave node. The ETSI EN 302 217 series defines the characteristics and requirements of microwave/millimeter wave equipment and antennas. Specifically, ETSI EN 302 217-2 [EN302217-2] specifies the essential parameters for systems operating from 1.4 GHz to 86 GHz. The data model includes configuration and state data according to the new Network Management Datastore Architecture [RFC8342]. The design of the data model follows the framework for management and control of microwave and millimeter wave interface parameters defined in [RFC8432]. This framework identifies the need and the scope of the YANG data model, 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, it 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 [MICROWAVE-RADIO-LINK], and it augments [RFC8343] 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 [RFC8343] as a basis. The data nodes for management of the interface protection functionality is broken out into a separate and generic YANG data module in order to make it also available for other interface types. The designed YANG data model uses established microwave equipment and radio standards, such as ETSI EN 302 217-2; the IETF Radio Link Model [MICROWAVE-RADIO-LINK]; and the ONF Microwave Model [ONF-model], as the basis for the definition of the detailed leafs/parameters, and it proposes new ones to cover identified gaps, which are analyzed in [RFC8432].1.1. 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 is 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 Transmitter Power Control
BBE: Background Block Error
BER: Bit Error Ratio
BPSK: Binary Phase-Shift Keying
CM: Coding Modulation
CT: Carrier Termination
ES: Errored Seconds
IF: Intermediate Frequency
MIMO: Multiple Input Multiple Output
RF: Radio Frequency
RLT: Radio Link Terminal
QAM: Quadrature Amplitude Modulation
QPSK: Quadrature Phase-Shift Keying
RTPC: Remote Transmit Power Control
SES: Severely Errored Seconds
TDM: Time-Division Multiplexing
UAS: Unavailable Seconds
XPIC: Cross Polarization Interference Cancellation
1.2. Tree Structure

2.2. Explanation of the Microwave Data Model
The leafs in the Interface Management Module augmented by RLT and CT
are not always applicable.
"/interfaces/interface/enabled" is not applicable for RLT. Enable
and disable of an interface is done in the constituent CTs.
The packet-related measurements "in-octets", "in-unicast-pkts",
"in-broadcast-pkts", "in-multicast-pkts", "in-discards", "in-errors",
"in-unknown-protos", "out-octets", "out-unicast-pkts", "out-
broadcast-pkts", "out-multicast-pkts", "out-discards", and "out-
errors" are not within the scope of the microwave radio link domain
and therefore are not applicable for RLT and CT.
