US Classification:

375316

Abstract:

In a communication system that utilizes DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), the primary site (102) and each of the secondary sites (104-108) includes a DMT receiver. Such a DMT receiver includes a discrete multi-tone decoder that receives a time domain discrete multi-tone symbol and produces an ordered data stream based on bit loading information and a data de-formatter, operably coupled to the discrete multi-tone decoder, wherein the data de-formatter receives the ordered data stream and produces a recovered data stream based on carrier channel allocation information.

International Classification:

H04N 714

US Classification:

370 17

Abstract:

In a communication system utilizing DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), infrastructure control channels are established in the following manner. Having obtained a plurality of site bit loading tables, the primary site (102) generates a control channel bit loading table from the plurality of site bit loading tables. From the control channel bit loading table, the primary site selects at least one carrier channel to function as the control channel. The selection is based on bandwidth requirements for the control channel.

International Classification:

US Classification:

370 17

Abstract:

In a communication system that utilizes DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), carrier channel allocations may be updated as follows. At periodic intervals, the primary site requests updating bit loading information from the secondary sites. Upon receiving the updated bit loading information, the primary site (102) determines an updated call bit loading table for each active call. From this, the primary site (102) determines whether current carrier channel allocation provides sufficient bandwidth. When the current carrier channel allocation does not provide the sufficient bandwidth, the primary site modifies the current carrier channel allocation to meet the bandwidth requirements.

International Classification:

H04B 140
H04J 300

US Classification:

370476

Abstract:

A data stream provided to a DMT transmitter (114) is altered to produce an ordered data stream. The ordered data stream is produced by storing the data stream using a first addressing scheme, and then reading the data using a second addressing scheme. The ordered data stream is then converted in to a DMT symbol which is transmitted to a DMT receiver (112). The DMT receiver (112), using the first and second addressing schemes, recovers the ordered data stream and then the original data stream.

Abstract:

In a communication system that utilizes DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), the primary site (102) and each of the secondary sites (104-108) includes a DMT transmitter. Such a DMT transmitter includes a discrete multi-tone encoder that receives an ordered data stream and produces an encoded data stream based on bit loading information, and a data formatter operably coupled to the discrete multi-tone encoder, wherein the data formatter receives transmit data entries and produces the ordered data stream based on carrier channel allocation information.

US Classification:

379 60

Abstract:

In a communication system that employs DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), call support infrastructure is obtained as follows. Having received a call request, the primary site (102) identifies targeted subscribers and target secondary sites, i. e. , the secondary sites having a targeted subscriber affiliated therewith. Next, the primary site determines a call bit loading table from the site bit loading tables of the target secondary sites. Having done this, the primary site selects, based on bandwidth requirements of the call, at least one carrier channel to provide the infrastructure support for the call.

International Classification:

US Classification:

370 951

Abstract:

In a communication system that utilizes DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), carrier channel allocations may be performed as follows. When a call request is received, the primary site (102) determines the number of required bits based on the bandwidth requirements of the call. Next, the primary site (102) determines whether the maximum bit loading of a given carrier channel exceeds the number of required bits. If yes, the primary site allocates a carrier channel having a bit loading that most closely matches the number of required bits. If no, the primary site allocates the carrier channel having the maximum bit loading to the call, then calculates a remaining number of required bits. From here, the primary site repeats the above process until a sufficient number of carrier channels have been allocated to the call.
