Publication number: 20020105950Abstract: A method of computer data transmission over a telecommunications network having a head end connected to a plurality of service units is provided. The method includes receiving a request for transmitting computer data over the network from a service unit, retrieving provisioning information for the service unit, and selectively assigning one or more data channels based on the provisioning information to transmit the computer data over the network to provide a data path with substantially constant data transfer bandwidth between a head end and the service unit.Type: ApplicationFiled: January 11, 2002Publication date: August 8, 2002Applicant: ADC Telecommunications, Inc.Inventors: Mark J.

Patent number: 6334219Abstract: A method for monitoring at least one telephony communication n-bit channel, wherein one of the bits is a parity bit, includes sampling the parity bit of the n-bit channel. A probable bit error rate is derived from the sampling of the parity bit. The probable bit error rate can be compared to a pre-determined bit error rate value to determine if the at least one telephony communication n-bit channel is corrupted. If the at least one telephony communication n-bit channel is corrupted, the at least one telephony communication n-bit channel is re-allocated to an uncorrupted and unallocated telephony communication n-bit channel. Further, at least one unallocated telephony communication channel can be periodically monitored and error data accumulated to indicate the quality thereof.Type: GrantFiled: June 28, 1996Date of Patent: December 25, 2001Assignee: ADC Telecommunications Inc.Inventors: Terrance J.

Patent number: 6282683Abstract: The communication system includes a hybrid fiber/coax distribution network. A head end provides for downstream transmission of telephony and control data in a first frequency bandwidth over the hybrid fiber/coax distribution network and reception of upstream telephony and control data in a second frequency bandwidth over the hybrid fiber/coax distribution network. The head end includes a head end multicarrier modem for modulating at least downstream telephony information on a plurality of orthogonal carriers in the first frequency bandwidth and demodulating at least upstream telephony information modulated on a plurality of orthogonal carriers in the second frequency bandwidth. The head end further includes a controller operatively connected to the head end multicarrier modem for controlling transmission of the downstream telephony information and downstream control data and for controlling receipt of the upstream control data and upstream telephony information.Type: GrantFiled: September 15, 1999Date of Patent: August 28, 2001Assignee: ADC Telecommunications, Inc.Inventors: Mark J.

Patent number: 5726607Abstract: A digitally controlled phase locked loop generates a derived clock signal that is frequency locked to a reference clock signal. The apparatus is comprised of a microcontroller, counter, digital to analog converter (DAC) and a voltage controlled crystal oscillator (VCXO) connected in a feedback loop arrangement. A frequency output derived from the VCXO periodically samples an incoming reference signal. The sampled count value is compared to an ideal count value associated with the same sampling time period. A microcontroller and software-based algorithm perform the phase comparison and loop filter operations of the phase locked loop (PLL).Type: GrantFiled: February 4, 1994Date of Patent: March 10, 1998Assignee: ADC Telecommunications, Inc.Inventors: Jeffrey Brede, Adam Opoczynski, James W.

Patent number: 5655068Abstract: A system monitors the performance of a communications network and isolates the location of equipment failures therein through analysis of performance error data. The system passively monitors the performance of the network, operating in the background during normal data and/or voice transmission. The head end generates and inserts multiple error codes, one for each remote unit, into the downstream traffic path. Each remote unit extracts and decodes its respective error code to determine whether a downstream error occurred. Each remote unit then calculates a new error code based on the result of the downstream decode and the respective upstream data message. The head end receives the upstream error codes from all the remote units, decodes them, and accumulates the error data from all remote units over a period of time. An error distribution is generated, and an analysis is performed thereon to isolate the location of error causing equipment failures.Type: GrantFiled: January 17, 1996Date of Patent: August 5, 1997Assignee: ADC Telecommunications, Inc.Inventor: Adam Opoczynski

Patent number: 5528579Abstract: A telecommunications system includes an added bit signalling method and apparatus for conveying signalling information between a head end and multiple remote ends connected over a passive distribution network. In accordance with the present invention, an added bit having an identifiable data sequence patterned thereon is appended to each channel within a succession of frames. In the system, the modified channels are broken up, routed reconstructed into a modified framing format and transmitted to their respective destination remote units. Because individual channels within a given frame are broken up and reconstructed into modified frames with channels from other frames, the framing information formerly identified by the framing bit is lost. The present invention therefore appends an added-bit sequence to each channel such that each channel sample carries its own multiframe and alignment information.Type: GrantFiled: June 11, 1993Date of Patent: June 18, 1996Assignee: ADC Telecommunications, Inc.Inventors: Mark S. Wadman, Adam Opoczynski, Mark D. Elpers

Patent number: 5453737Abstract: A master/slave communication and control system includes a master controller and a plurality of slave subsystems, the master controller connected with the slave subsystems through first and second independent serial data buses, one of the data buses providing a working data bus, the other data bus providing a standby data bus. The master controller generates a A/B select signal applied to each of the slave subsystems to select which of the A or B data buses the slave .subsystems will use to communicate with the master controller. Each of those slave subsystems generates an independent request for communication signal, carried on an input request line to the master controller. A plurality of kill signals are generated by the master controller and applied over independent kill lines to each of the slave subsystems, whereby the master controller may send the kill signal to any one of the slave subsystems.Type: GrantFiled: October 8, 1993Date of Patent: September 26, 1995Assignee: ADC Telecommunications, Inc.Inventor: Adam Opoczynski

Patent number: 5408462Abstract: A protection switching system is disclosed which includes a plurality of telecommunications modules for processing and/or switching telecommunications signals. A first module provides signals to one pair of modules, which are in turn connected to another pair of modules. Each pair of modules includes a working and a standby module. The standby module controls the switching of all the modules in the system which require switching in the event that the standby module is activated. A controller monitor circuit monitors the faults present on the working modules and, if a fault is detected, signals the corresponding standby module, which in turn provides the protection switching.Type: GrantFiled: October 7, 1993Date of Patent: April 18, 1995Assignee: ADC Telecommunications, Inc.Inventor: Adam Opoczynski
