This paper presents a technology and architecture perspective for evolving today's copper access network optimized for POTS to a fiber access network providing both narrowband and broadband services.Architectures are assessed using application studies on actual routes in Bell Canada. Two architectures emerge as serious candidates (i.e., competitive with copper) for providing POTS service in 1992:the double star the star-bus. Tradeoffs between these architectures relating to POTS and broadband upgrade are discussed.
Telephone companies and cable operators have many needs in common. Both wish to increase revenues by adding new services. Both plan to convert to fibre optics in order to lower costs in installation, operations and maintenance. Each must provide basic services economically while replacing obsolete equipment and infrastructures.
Each year, network operators devote a large portion of their revenues to the provision and maintenance of network‐based services and equipment. Lately, activities such as installing equipment at a customer site and detecting and repairing network problems have become an area of concern as organizations strive to minimize technological impacts and achieve operations savings.
This paper is divided into three parts. First, the reader is provided with a description of the Consortel network architecture. This functional description is then completed by a description of the software applications that support network operations activities. Finally, economic considerations are examined in the implementation of this digital distribution network.
