Description (English):

IEC 60728-7-3:2009 specifies requirements for the Hybrid Fibre Coax (HFC) Outside Plant (OSP) Power Supplies (PS). This standard is part of a series developed to support the design and implementation of interoperable management systems for evolving HFC cable networks. The purpose of the standards is to support the design and implementation of interoperable management systems for evolving HFC cable networks. The Power Supply to Transponder Interface Bus (PSTIB) specification describes the physical (PHY) interface and related messaging and protocols implemented at the Data Link Layer (DLL), layers 1 and 2 respectively in the 7-layer ISO-OSI reference model, that support communications between compliant transponders and the managed OSP power supplies and other related power equipment to which they interface. It constitutes a technical revision and includes the following significant technical changes with respect to the previous edition: All changes from standard ANSI/SCTE 25-3 v1.0 to standard ANSI/SCTE 25-3 v1.1 (2005) have been taken into account in this second edition. Clause 7 is based on standard ANSI/SCTE 110 (2005). Addition of informative Annex A concerning hybrid management sub-layer.

Abstract

Overview - IEC 60728-7-3:2009 (PSTIB) for HFC OSP power monitoring

IEC 60728-7-3:2009 specifies the Power Supply to Transponder Interface Bus (PSTIB) for Hybrid Fibre Coax (HFC) Outside Plant (OSP) power supplies. The standard defines the physical (PHY) interface and the Data Link Layer (DLL) messaging and protocols (OSI layers 1 and 2) that enable communications between compliant transponders and managed OSP power equipment. Edition 2.0 incorporates updates from ANSI/SCTE 25-3 v1.1 (2005), aligns Clause 7 with ANSI/SCTE 110 (2005), and adds an informative Annex A on the hybrid management sub-layer (HMS).

Key topics and technical requirements

Scope and architecture: Reference architecture for forward and return channels in HFC outside plant monitoring.
Physical layer (PHY): Connector types (e.g., RJ‑45 references), interface signals, line balance, cable length limits, transponder power, indicators and alternative PHY options.
Data Link Layer (DLL): Packet structure, start/end framing, source/destination addressing, identification, datagram formats, checksums and DLE sequences.
Timing and synchronization: Message timing, transmission requirements and interaction rules to ensure robust communications.
Datagram set and commands: Defined DLL datagram types and commands such as Get_Configuration, Get_Power_Supply_Data, Power_Supply_Control, Get_Generator_Data, Generator_Control and standard responses (Request_Processed, Invalid_Request).
Interoperability and compliance: Interface and implementation compliance requirements, revision control and reserved address ranges.
Informative material: Annex A covering the hybrid management sub‑layer (HMS) document family and guidance for implementers.

Applications and practical value

This standard is intended for use in the design, implementation and operation of HFC network management systems that monitor and control OSP power equipment. Practical applications include:

Designing PSTIB‑compliant transponders, power supplies and interface hardware
Implementing firmware/software for DLL messaging, datagram parsing and command handling
Enabling interoperable remote monitoring and control of battery strings, generators and rectifiers in HFC outside plant
Specifying cabling, connectors and RS‑485 style interfaces for field installations
Integrating OSP power monitoring into broader Hybrid Management Sub‑Layer (HMS) or network management systems

Who should use this standard

Cable network operators and system architects
Equipment manufacturers (transponders, power supplies, monitoring modules)
System integrators and network management software developers
Field engineers and test/validation teams ensuring interoperability and compliance

Related standards and references

ANSI/SCTE 25‑3 (v1.0 → v1.1) - incorporated updates
ANSI/SCTE 110 (2005) - basis for alternative PHY clause
IEC 60728 series - broader HFC cable network standards

Keywords: IEC 60728-7-3, PSTIB, HFC OSP, power supply to transponder interface bus, hybrid fibre coax, PSTIB datagrams, data link layer, physical layer, OSP power monitoring.
