Paper Abstract

Hybrid fiber-coax (HFC) systems have been developed to efficiently deliver television and other broadband services along with voice-grade services to the subscriber's premises. The efficiency of an HFC system, from both a call processing and an economic point of view, is enhanced by providing an integrated interface into the local digital switch (LDS) for the voice- grade services. Two interfaces in the public domain that can be used to provide the integrated voice-grade interface to the LDS are known as the TR-08 Interface, defined in Bellcore's Technical Reference document TR-NWT-000008, and the TR-303 Interface, defined in Bellcore's Technical Reference document TR-NWT-000303. This paper presents a brief overview of the TR-08 and TR-303 interfaces to LDSs. The advantages of using the TR-303 Interface for an HFC system's voice-grade interface to the LDS are discussed for the operations, administration, maintenance, and provisioning (OAM&P) functions. Also discussed are the economic considerations of providing plain old telephone service (POTS) and integrated services digital network circuits in HFC systems via TR-08 and TR-303 interfaces to the LDS.
