US Patent:

6711260, Mar 23, 2004

Filed:

Aug 18, 1999

Appl. No.:

09/376485

Inventors:

Mark A. Russell - Austin TX
Stephen Weinert - Arlington TX

Assignee:

SBC Technology Resources, Inc. - Austin TX

International Classification:

H04M 100

US Classification:

37939901, 37939002, 37941304

Abstract:

A filter passing only desired frequencies is selected according to a desired level of service for copper lines. At a point of access between a loop plant and Central Office, the filter is interposed in series over a telephone service line to provide spectral containment by restricting the frequencies of transmission passing along the line. The filter is preferably mounted within a 6-pin module used in a protector block at the Central Office or remote terminal facility, interfaces with a 5-pin module, or is placed upstream or downstream of a protector block such that it does not interfere with the operation thereof. Service is activated, and the spectral containment apparatus prevents the transmission of unexpected or unintended services over the line.

Appl. No.:

11/262818

Inventors:

Mark A. Russell - Austin TX, US
Stephen Weinert - Arlington TX, US

Assignee:

AT&T Labs, Inc. - Austin TX

International Classification:

H04M 1/00
H04M 9/00

US Classification:

37939901, 37920101, 37920704, 37939002, 37941204

Abstract:

A method for providing spectral containment over telecommunications service lines is provided. The method includes selecting a filter having spectral characteristics corresponding to a predetermined passband. The method also includes connecting the filter in series to at least one loop used to provide at least one telecommunications service to a customer. The method further includes activating service over the at least one loop. The filter attenuates signals transmitted on frequencies outside of the predetermined passband over the at least one loop.

Filed:

Dec 14, 2007

Appl. No.:

11/956994

Inventors:

Mark A. Russell - Austin TX, US
Stephen Weinert - Arlington TX, US

Assignee:

AT&T Labs, Inc. - Austin TX

International Classification:

H04M 1/00
H04M 9/00

US Classification:

37920101, 37920704, 37939002, 37939901, 37941304

Abstract:

A service to a user is prevented by providing, to the user, at least one communication link used to provide multiple services to the user. The plurality of services are activated over the at least one communication link. Transmission for the prevented service is prevented based on at least one characteristic of the at least one communication link over which the prevented service would be provided.

US Patent:

Filed:

Jul 22, 1997

Appl. No.:

8/898166

Inventors:

Mark Russell - Austin TX
Vladimir Friedman - Scotch Plains NJ
Stuart D. Sandberg - Arlington MA

Assignee:

Analog Devices, Inc. - Norwood MA
Aware Inc. - Bedford MA

International Classification:

H03H 730
H03H 740

US Classification:

375233

Abstract:

A method and system which combines a properly designed FEC and the periodic transmission of known symbols to obtain a desired error performance in a point-to-multipoint digital transmission system employing a DFE which induces error propagation. A transmitter unit includes a forward error correction encoder (FEC) which implements a code to information provided to an input of a data interleaver having block length N and interleaving depth D, and a data modulator which is coupled to an output of the data interleaver to receive a stream of data symbols. At least one receiver unit includes a decision feedback equalizer (DFE) which includes a feedback filter and provides an input to a data deinterleaver having block length N and interleaving depth D, and a FEC decoder which receives data from an output of the data deinterleaver. Sequences of known symbols of length at least equal to the length of the feedback filter are periodically added to the output of the data interleaver. The receiver unit uses knowledge of the sequence to pass correct data to the feedback filter.

Assignee:

Aware Inc. - Bedford MA

International Classification:

H03M 1300

US Classification:

714776

Abstract:

A forward error correction (FEC) system and method for use in a multipoint-to-point frame based synchronized transmission communication system in which data from users are sent in selected portions of data frames having coded symbols added thereto by encoders associated with each user. The number of bits per user assigned portions of data frames is established as an integer number of FEC code symbols. The interleaving depth is set equal to a multiple of the total number of code symbols sent by a user in a data frame. The encoders are synchronized such that all of the encoders start processing associated interleaving frames at the same time. In exemplary embodiments, the communication systems include DWMT and TDM communication systems.
