Improved VoDSL service Provision

摘要

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 Systems (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 network-telephony interface connected to said internal network and coupled to a customer premises telephony appliance; a network-data interface connected to said internal network and coupled to a customer premises data appliance; a controller arranged to control said switch in order to establish packet transfer paths between said modem and said interfaces to complete calls between said appliances and entities on the external network; and means for transferring control and information signals between said controller and a computing function in order to adapt the controller to provide alternative packet transfer paths dependent on predetermined conditions in order to provide one or more additional CPE services. <IMAGE>
