Abstract:
Growth of a distributed communication system (20) is facilitated through dynamic addition of distribution elements (22, 40, 50). A new element may be added to a network of elements by first establishing a connection (42, 44, 46, 48) between the new element and an existing element in the network. At least one address (322, 324) is assigned to the new element from a pool of addresses (310, 312) maintained at the existing element. At least one pool of addresses (326, 328) is issued to the new element, permitting the new element to dynamically add another new element. Information packets are routed through the network by determining a forwarding equivalency class (FEC) (400) for each subscriber unit (26) accessing the network. The FEC to which each subscriber unit belongs is based on the point (22) at which the subscriber unit accesses the network. Information packets are routed from a distribution element (40, 50) by determining the next element (22, 40, 50) based on the FEC for the destination subscriber unit.
Abstract:
An object of the present invention is to assemble all modules of a data broadcast via the internet access, when the receiving conditions of radio waves become poor due to, for example, bad weathers. When a reception condition monitoring means 6 determines that the receiving conditions become poor, reception method changing means 7 switches on an internet access means 10. At this time, a module detection means 8 acquires a module list registered in advance in a module memory means 4 to detect a module which has not been received so as to acquire only this module which has not been received by the internet access.
Abstract:
A MSO deploying a standard OLT, and installed with ONUs to be used by customers to whom the MSO can connect using optical fiber. For customers that cannot be reached with optical fiber, the MSO deploys a converter between the optical fiber and the coax network so that the MSO can use the same standard OLT, and use CNUs for those customers attached to the coax network.
Abstract:
A method, system and computer program for transmitting at least two payloads in a downstream traffic phase of a time-division duplex (TDD) cycle with a single preamble from a headend followed by concatenated payloads without intervening preambles, whereby the payloads are ranked by increasing modulation profiles. The preamble, and concatenated and ordered set of payloads are then transmitted to two or more predetermined customer premise equipments (CPEs).
