29、ent, systems and installations for head-end reception, processing and distribution of television and sound signals and their associated data signals, and processing, interfacing and transmitting all kinds of signals for interactive services using all applicable transmission media. All kinds of netwo
30、rks like CATV-networks, MATV-networks and SMATV-networks, individual receiving networks and all kinds of equipment, systems and installations installed in such networks, are within this scope. The extent of this standardization work is from the antennas, special signal source inputs to the head-end
31、or other interface points to the network up to the system outlet or the terminal input, where no system outlet exists. The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia terminals, etc.) as well as of any coaxial and optical cables and accessories therefore is ex

33、Power Supply to Transponder Interface Bus (PSTIB) specification 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 series developed to support the design and implementation of interoperable managem
34、ent 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 re
35、lated 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. This st
36、andard describes the PSTIB PHY and DLL layer requirements and protocols that must be implemented to support reliable communications between all type 2 and type 3 compliant OSP transponders on the HFC plant and managed OSP power supplies and related hardware. Any exceptions to compliance with this st
37、aneard will be specifically noted as necessary. Refer to Table 1 for a full definition of the type classifications. Transponder type classifications referenced within the HMS series of standards are defined in Table 1. Table 1 Transponder type classifications Type Description Application Type 0 Refe

39、the head-end Type 1 Refers to stand-alone transponder equipment (legacy or new), which can be upgraded to support the specifications This transponder interfaces with legacy network equipment through proprietary means. Type 1 is a standards-compliant transponder (either manufactured to the standard o

It can be factory or fie

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 defined in the standards. It may or may not support the physical s
42、pecifications defined in the standards. It can be factory-installed. It may or may not be field- installed.
