Recently published Broadband Forum Work Items (November 2025)

The Broadband Forum is pleased the share our latest published work, which may
be accessed directly through our online technical library
(https://www.broadband-forum.org/technical-library/).

TR-106a6 Data Model Template for CWMP Endpoints and USP Agents
The data model template provides the foundational structure for the TR-181
Device:2 data model, ensuring consistent structure and approach to the design
of the data demo.

TR-181i2a20 Device:2 Data Model
The Device:2 data model defines the full information model that is used for the
management and control of devices through both the TR-069 and USP protocols,
such as the configuration, management, and control of multiple AP Wi-Fi
systems, software management within the residential gateway devices, and bulk
data collections of telemetry data.

TR-369a4c2 User Services Platform (USP)
TR-369 is the full USP protocol specification, providing a means for multiple
controllers to simultaneously manage and control remote devices deployed by
service providers to customer premises locations, while applying appropriate
access controls to each controller.

TR-383a9 Common YANG Modules for Access Networks
The TR-383 specifications define YANG data models for the management of
Broadband-Forum-specified access network equipment and network functions used
across many deployment broadband scenarios.

TR-423i3 PON PMD Layer Conformance Test Plan
The TR-423 test specification provides a set of detailed, physical layer
conformance test cases, covering the ITU-T XG(S)-PON, NG-PON2 TWDM, and HSP TDM
technologies.

TR-452.4 QED Measurement Formats
TR-452.4, part of the Quality Attenuation (∆Q) specification series, provides
standardized data formats for reporting quality attenuation measurements in
broadband networks, crucial for industry-wide comparison and integration of
performance data.

TR-452.7 Quality Attenuation Measurements Using L2 and L3 Active Protocols in
Multicast Environments The Quality Attenuation (∆Q) measurement general
approach is described in TR-452 specification series, including implementation
details for  using Network Layer (L3) Active Measurement Protocols used in
unicast networks. This latest TR-452.7 specificaiton within the series, allows
Quality Attenuation (∆Q) measurement and analysis in Multicast Environments
such as Layer 2 Multipoint Scenario and Layer 3 IPTV.

TR-459i3c1 Multi-Service Disaggregated BNG with CUPS. Reference Architecture,
Deployment Models, Interface, and Protocol Specification TR-459 specifies the
architecture and requirements for a Disaggregated Broadband Network Gateway
(DBNG). The separation of the control plane and user plane in the DBNG enables
more efficient use of resources and simplifies Operations.

MR-459.5 Unlocking the Potential of Disaggregated BNG; Key Opportunities for
Service Providers The MR-459.5 Marketing Report provides a high level, summery
of the key aspects and approaches within the TR-459 specification, serving as
an engineering primary to the full specifications.

TP-469a4 Conformance Test Plan for USP Agents
The TP-469 specification provides the test cases required to verify if a USP
Agent is conformant to the USP protocol specific (TR-369). This test plan is
used as the basis of the Forum’s USP certification program. TR-507 Multi-Tenant
5G FWA

The TR-507 specification provides the architectural design, and nodal
requirements to support multiple subscribers served by a single fixed wireless
access connection, while maintaining subscriber management and identity
controls that would be typical to connections served by fixed wired connections.

MR-516 Benefits of Multi-Tenant Fixed Wireless Access
The MR-516 Marketing Report provides a high level, engineering summary of the
use cases and benefits to the architectural approach defined by the TR-507
specification.

The Broadband Forum encourages our partner SDO’s to review these materials, to
ensure work their progress references these latest materials and avoids
duplication of efforts.  We look forward to the continued collaboration with
our peers as we all continue to progress this important work.

Sincerely,

Lincoln Lavoie,
Broadband Forum Technical Committee Chair
