SUBSCRIBER ACCESS TO THE BROADBAND ISDN WITH A UNIVERSAL USER-NETWORK INTERFACE

摘要

A broadband-subscrlber access for communication services (e.g. speech, data, video telephony) with a universal user-network interface at about 150 Mbit/s is proposed. The network-terminating equipment (NT), as well as the subscriber-line equipment (LE) in the switching center, are designed such that they offer a bidirectional transmission capacity of 153.6 Mbit/s between the subscriber premises and the exchange. At one time, several broadbandterminal equipments (B-TE) may have access to different types of channels (e.g. B, H1, H4). The B-TE's access to the channels is regulated via the D16-channel. W distribution is marginally regarded.
