33、le networks including equipment and associ-ated methods of measurement for headend reception, processing and distribution of television signals, sound signals and their associated data signals and for processing, interfacing and transmitting all kinds of signals for interactive services using all ap
34、plicable transmission me-dia. This includes CATV1-networks; MATV-networks and SMATV-networks; individual receiving networks; and all kinds of equipment, systems and installations installed in such networks. The extent of this standardization work is from the antennas and/or special signal source in-
35、puts to the head-end or other interface points to the network up to the terminal input. The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia termi-nals, etc.) as well as of any coaxial, balanced and optical cables and accessories thereof is excluded. The following
36、differences exist in some countries: The Japanese de facto standard (NCTEA S-006) concerning requirements for the HFC out-side plant management, which was published in 1995, has already been available in Japan. The purpose of this standard is to support the design and implementation of interoperable
37、 management systems for HFC cable networks used in Japan. _ 1This word encompasses the HFC networks used nowadays to provide telecommunications services, voice, data, audio and video both broadcast and narrowcast.BS EN 60728-7-3:2009 8 60728-7-3 IEC:2009(E) CABLE NETWORKS FOR TELEVISION SIGNALS, SOU
38、ND SIGNALS AND INTERACTIVE SERVICES Part 7-3: Hybrid fibre coax outside plant status monitoring Power supply to transponder interface bus (PSTIB) 1 Scope This part of IEC 60728 specifies requirements for the Hybrid Fibre Coax (HFC) Outside Plant (OSP) Power Supplies (PS). This standard is part of a
39、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
40、 In-terface Bus (PSTIB) specification describes the physical (PHY) interface and related messag-ing 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 trans-ponders and the managed
41、OSP power supplies and other related power equipment to which they interface. This standard describes the PSTIB PHY and DLL layer requirements and protocols that shall be implemented to support reliable communications between all type 2 and type 3 compliant OSP transponders on the HFC plant and mana
42、ged OSP power supplies and related hardware. Any exceptions to compliance with this standard will be specifically noted as necessary. Transponder type classifications referenced within the HMS series of standards are defined in Table 1. Table 1 Transponder type classifications Type Description Appli
43、cation Type 0 Refers to legacy transponder equip-ment which is incapable of supporting the specifications This transponder interfaces with legacy network equipment through proprietary means. This transponder could be managed through the same management applications as the other types through proxies
44、 or other means at the head-end. Type 1 Refers to stand-alone transponder equipment (legacy or new), which can be upgraded to support the specifica-tions This transponder interfaces with legacy network equipment through proprietary means. Type 1 is a standards-compliant transponder (either manufactu
45、red to the standard or upgraded) that con-nects to legacy network equipment via a proprietary interface. Type 2 Refers to a stand-alone, compliant transponder This transponder interfaces with network equipment designed to support the electrical and physical specifications defined in the standards. I
46、t can be factory or field-installed. Its RF connection is independent of the monitored NE. Type 3 Refers to a stand-alone or embedded, compliant transponder This transponder interfaces with network equipment designed to support the electrical specifications de-fined in the standards. It may or may n
47、ot support the physical specifications defined in the standards. It can be factory-installed. It may or may not be field-installed. Its RF connection is through the monitored NE.
