Abstract

In current voice telephony, CATV, and wireless networks, traffic is channelized for both access and transport. This channelization is wasteful of resources where multiple services have varying demands for bandwidth and holding times, or a service generates traffic that is bursty in nature. The invention solves these problems by providing flexible and adaptable multi-service access to the networks. Customer requirements are checked by monitoring traffic on a local access at a connection request and/or during the established connection, and the local access is configured according to the transmission requirements. The local access can also be configured in response to the network information. In further realizations, either or both the CPE connector and access module include common bus architecture which forms a backbone LAN for handling a multiplicity of CPEs and/or networks.
