Abstract: A dynamically self-configuring and re-configuring dual homing connection (DH) for loop-free data communication between a first communication network and a second communication network, the DH acquiring either a Symmetrical configuration or an Asymmetrical configuration.

Abstract: Technology for providing subscribers with communication services in accordance with their agreements with a service provider, that comprises: a) determining a plurality of subscribers to be connected to the service provider via a distribution unit located in an access network; b) selecting a default advanced broadband technology (DABT) for the distribution unit; c) in the distribution unit, providing a plurality of communication devices to reserve for each of the plurality of subscribers, irrespective of their agreements reached with the service provider, an individual communication link for supplying broadband communication services based on the selected DABT; while d) enabling each of the plurality of subscribers to receive services in accordance with their respective agreements with the service provider.

Abstract: Jitter is limited in the mapping of a first telecommunications signal into a second telecommunications signal, by, upon receiving an indication that the payload pointer of the second telecommunications signal is moving in a first direction, generating a compensative payload pointer movement of the first telecommunications signal in a second direction which is opposite the first direction. The invention has particular application to the mapping of three E3 telecommunications signals which are in the format of a TUG-3 signal into an STS-3C SONET telecommunications signal in the STM-1 VC-4 format. When the STS-3C signal requires a pointer movement due to frequency compensation in the system, a compensative pointer movement at the TUG-3 level avoids eight units of jitter in the TUG-3 signal which could adversely affect system performance.
