Enhanced performance vodsl

Abstract

Voice over Digital Subscriber Line (VoDSL) is an emerging technology, and as such requires subscriber acceptance and take-up both for the future development of this technology and to repay access network operator investment in VoDSL equipment. The present invention provides an improved equipment architecture and improved methods of separating VoDSL equipment to enhance performance and/or enable the provision of improved services. In one aspect the invention provides a Digital Access System (DAS) Customer Premises Equipment (CPE) comprising: an internal packet switched network comprising a switch; a DAS modem connected to said internal network and arranged such that in use the internal network is coupled to an external packet switched network by a DAS link over an access network; a controller arranged to control said switch in order to establish packet transfer paths between said modem and one or more internal network interfaces to customer appliances connected to the CPE in order to complete calls between said appliances and entities on the external network; wherein the CPE is arranged to reconfigure parameters corresponding to a first layer dependent on parameters corresponding to a second layer.
