Local Access Network Management

Abstract

The local access network can be considered as the first or final hop in the transmission network through which all network operator-supplied services pass. Most of these services pass through the local access network twice — once for each end connection. Only recorded information and enquiry services have a single pass through this network. For the purposes of this chapter, the local access network is regarded as starting at the transmission-terminating equipment in the serving local exchange and ending at the network-termination equipment at the customer’s premises. Depending on the technology in question, the transmission-terminating equipment may be main distribution frame (MDF), digital distribution frame (DDF) or multiplexing equipment.
