A method and apparatus for transmitting delay sensitive information (DSI) and non-delay sensitive information (NDSI) over a communication link where initial DSI packets are delayed to reduce the number of conflicts between DSI and NDSI. The delay applied to the DSI is based on parameters such as the transmission periodicity of the DSI packets and the packet length of the NDSI being transmitted.

Dynamic latency assignment methodology for bandwidth optimization of packet flows

A multi-services access system, such as a multi-services digital loop carrier (DLC) system for a telecommunications network, has a packet-mode card, such as a digital subscriber line (DSL) card, configured to receive data packets corresponding to one or more data signals and derived-voice packets from a single packet-mode customer premises equipment (CPE) unit, wherein the packet-mode card determines whether each received packet is a data packet or a derived-voice packet. The access system also has a packet interface configured to receive the data packets from the packet-mode card and to transmit the data packets to a packet-switched network for packet-based switching. In addition, the access system has a derived-signal server configured to receive the derived-voice packets from the packet-mode card and to convert the derived-voice packets into a digital voice stream, as well as a controller and a circuit interface configured to receive the digital voice stream from the derived-signal server and to transmit the digital voice stream to a circuit-switched network for circuit-based switching. Since the access system is able to assign resources dynamically to packet-mode CPE units (as opposed to prior-art DLC systems, which have resources pre-assigned), the system of the present invention is able to utilize system resources more efficiently. Moreover, since the system has an internal derived-signal server, there is no need to transmit derived voice signals outside of the system for conversion.

Digital loop carrier or other multi-services access system as a data and voice packet server

A headend of a shared data channel receives data packets, each data packet being addressed to a user of the shared data channel. A buffer of the headend queues the data packets, and a router of the headend assigns high transmittal priority to data packets addressed to users who have more recently received a previous data packet and assigns low transmittal priority to data packets addressed to users who have relatively less recently received a previous data packet, wherein the low transmittal priority is a lower priority than the high transmittal priority.
