A time slot management method for use in a time division multiple access system that couples a line terminator via a tree-like network to a plurality of network terminations is provided. At least one grant is transmitted by the line terminator towards a network terminator in order to allocate at least one adjacent subsequent corresponding upstream time-slot to the network terminator. The grant is received by the network terminator from the line terminator, and it is recognized if the at least one grant is associated with the network termination. Upon recognition of the at least one grant being associated with the network termination by the network terminator, overhead data in the first time slot of the at least one time slot and payload data in each potential adjacent subsequent time slot of at least one time-slot allocated to said network terminator is transmitted.

A method of providing an Internet protocol television service to a subscriber, and a network element to execute this method. At an acquisition tier, IPTV packets are generated from video stream data of one or more video channels and transmitted to a FCC server cluster at a client-facing tier. IPTV packets associated with one of the one or more video channels selected by the subscriber are delivered from the deliver server cluster to a receiver of the subscriber at a client tier wherein the IPTV packets associated with the one of the one or more video channels are reassembled at said receiver into a coherent video stream. Said generated IPTV packets are routed from a network () of a TV broadcaster to networks of one or more TV operators or from a network of a TV operator to networks of one or more TV operators by means of IPTV service routers installed at an intertwine tier arranged between the acquisition tier and the client-facing tier.

A point-to-multipoint telecommunication system can be made more flexible by providing upstream units with generators and locators for generating at least two subsequent overhead cells located next to each other and neighbouring a larger number of data cells for supplying system information. Downstream units are provided with detectors for detecting the subsequent overhead cells. This new signal flame structure allows a larger number of data cells to be exchanged without being interrupted by an overhead cell. Each cell consists of at least 53 bytes in accordance with the Asynchronous Transfer Mode or ATM standard. The at least two overhead cells comprise two overhead cells for supporting 54 data cells, or comprise three overhead cells for supporting 103 data cells. The point-to-multipoint telecommunication systems comprise passive optical networks, with upstream units corresponding to line terminators, and with downstream units corresponding to network terminators.

An access node () that is preferably a Flow-Aware Ethernet DSLAM configured to transmit Ethernet data frames between subscribers () and an aggregation network (). The access node comprises a first memory () for storing classification rules and a second memory () for storing flow rules. These rules are applied by a classification agent () and by a service agent () to information extracted from incoming data frames in order to infer flow awareness information of outgoing frames corresponding to these incoming data frame. In this way, the subscriber access network evolves to a multi-service architecture by replacing ATM with Ethernet for cost reasons. The concept of 'flow awareness' is applied to the present access node. With respect to known tunnel-based Ethernet DSLAMs, the present access node removes all dependency on correct encapsulation or labeling at the customer side and at the service provider side.

Systems for transmitting information from terminal systems () via access multiplexers () comprising virtual forwarder systems () to networks are made less complex by inserting at the terminal systems () virtual forwarder internet protocol addresses () into destination fields of internet protocol headers for heading the information and by inserting destination internet protocol addresses () into routing fields of the internet protocol headers. Both the terminal systems () and the access multiplexers () should be made capable of dealing with internet protocol headers of the internet protocol version-4 or the internet protocol version-6 or higher, which comprise a destination field and a routing field. The destination internet protocol addresses () in the routing fields allow distinguishment between different classes of services and/or applications used by the terminal system () simultaneously, without the access multiplexers () being obliged to unpack (parts of) the information and to detect (parts of) the information at higher layers.
