A system for causing application of sealing current to one or more local telephony loops has a current source; a switching interface for connecting the current source to the one or more telephony loop interfaces; and a machine-readable instruction accessible to the switching interface, the instruction providing intelligence to the switching interface for identifying the one or more loops to be serviced, the time period for current application to each loop serviced, and a sequence order when more than one loop is serviced.

Control circuit for causing cyclic application of sealing current for local loops supporting data network telephony

A multi-dwelling unit (MDU) module is configured for providing telephony communicating services and non-telephony services. The MDU module includes a motherboard and a plurality of service units connected to the motherboard. Each one of said service units and the motherboard are jointly configured for providing non-telephony service and telephony service to a plurality of service subscribers. The motherboard is configured for providing overload power management to limit power consumption associated with said telephony services during an overload condition and for providing lifeline power management to limit power consumption associated with said non-telephony services during a power outage condition. The MDU module optionally includes lightning primary surge protection blocks configured for being connected to the service units. The MDU module includes a passive heat dissipation assembly that is configured for absorbing heat generated by the motherboard and the service units and for passively dissipating the heat.

Distributed communication equipment architectures and techniques are disclosed. A host system includes an expansion unit through which control information and communication traffic may be exchanged with an expansion system. The expansion system is thereby controllable by a controller at the host system, significantly simplifying the design and reducing the cost of the expansion system. The expansion unit for a host system may also provide one or more configurable communication link interfaces. Each configurable interface may be independently configured as a network-side interface for connection to upstream communication equipment or as an access-side expansion interface for connection to an expansion system, allowing provisioning of network and access interfaces at the host system as needed.

IGMP is a protocol for managing and controlling multicast of data streams to a plurality of end users connected to a telecommunications network through an access system. A novel implementation of IGMP for multicasting data streams in an xDSL access network system is disclosed. DSLAM (Digital Subscriber Line Asynchronous Multiplexer) or ASAM (ATM Subscriber Access Multiplexer) is used in the access network system and interfaces between the telecommunications network and the plurality of end users. IGMP signals are terminated at LT (Line Termination). A better scalability of the access system can be achieved, resulting in increased numbers of end users.

Access network architecture for multicasting using xDSL and IGMP

Whenever a DSLAM or a network node receives a Group Join message, it compares the MAC address of the originating STB to that of previous Join messages with their existing connections. If a match is found, then the DSLAM will initiate a GSQ for the group of the matching previous Join request. If there is not enough resources to satisfy the requirements of Group Join messages, then it may either be ignored, or queued for later processing, once the normal GSQ sequence is complete and resources are available. If the multicast group is no longer needed, the connection to the group is then terminated, as per normal GSQ processing. This frees up bandwidth for any new Join messages. The normal GSQ processing clears the trouble caused by the loss of Leave Message.
