Patent number: 6850618Abstract: A splitterless interface between a digital subscriber line (DSL) and the central office equipment that can receive and isolate the low frequency voice data and high frequency digital data from a telephone line. This interface can also mix and transmit low frequency voice data and high frequency digital data onto a telephone line. For POTS band frequencies, a reactive impedance coupled across the two-wire interface of the POTS line card, and serially coupled to the line side of the DSL coupling transformer, has an open state magnitude. The magnitude of the line side windings of the DSL coupling transformer is low at POTS band frequencies. POTS band signal power is therefore delivered to the POTS line card. For DSL band frequencies, the reactive impedance across the two-wire interface of the POTS line card has a closed state magnitude. The POTS line card is therefore essentially short-circuited at DSL band frequencies, and DSL band signal power is delivered to the DSL modem.Type: GrantFiled: May 15, 2000Date of Patent: February 1, 2005Assignee: Centillium Communications, Inc.Inventors: Hessam Mohajeri, Serdar Kiykioglu, Heron Babaei

The POTS line card is therefore essentially short-circuited at DSL band frequencies, and DSL band signal power is delivered to the DSL modem. The frequency band in which the reactive impedance transitions from an open state magnitude to a closed state magnitude corresponds to the frequency band between the POTS frequency band and the DSL frequency band.Type: GrantFiled: May 25, 2001Date of Patent: November 30, 2004Assignee: Centillium Communications, Inc.Inventor: Serdar Kiykioglu

Patent number: 6754285Abstract: One embodiment of the present invention provides a method for conditioning a signal for transmission in a DMT-based communication system, the method comprising: converting the signal in a digital environment of the DMT-based communication system into a pre-clipped signal to avoid subsequent analog clipping in an analog environment of the DMT-based communication system. Another embodiment of the present invention provides a signal conditioner for conditioning a signal for transmission in a DMT-based transmission system, the signal conditioner comprising: a digital environment configured to convert the signal into a pre-clipped signal to avoid subsequent analog clipping in an analog environment of the DMT-based communication system.Type: GrantFiled: August 1, 2000Date of Patent: June 22, 2004Assignee: Centillium Communications, Inc.Inventor: Serdar Kiykioglu

Publication number: 20030012352Abstract: A metering tone is applied to a transmission line by a DSL modem on behalf of a voice circuit, rather than being applied directly by the voice circuit. Various techniques for applying the metering tone to the data path are described. Because the metering tone is passed to the network in the data path rather than in the voice path, the tone is subject to the high-pass filtering associated with the data path rather than the low-pass filtering associated with the voice path. Accordingly, the metering tone is not attenuated by the splitter or by analogous features in a splitterless system.Type: ApplicationFiled: July 12, 2002Publication date: January 16, 2003Inventors: Serdar Kiykioglu, Guozhu Long, Sanjay Gupta

Publication number: 20020031217Abstract: A digital subscriber line and POTS voice interface between a telephone line and central office equipment is provided. For POTS band frequencies, a reactive impedance coupled across the input of the POTS line card, and serially coupled to the line side of the DSL coupling transformer, has an open state magnitude. The magnitude of the line side windings of the DSL coupling transformer is low at POTS band frequencies. POTS band signal power is therefore delivered to the POTS line card. For DSL band frequencies, the reactive impedance across the input of the POTS line card has an closed state magnitude. The POTS line card is therefore essentially short-circuited at DSL band frequencies, and DSL band signal power is delivered to the DSL modem. The frequency band in which the reactive impedance transitions from an open state magnitude to a closed state magnitude corresponds to the frequency band between the POTS frequency band and the DSL frequency band.Type: ApplicationFiled: May 25, 2001Publication date: March 14, 2002Inventor: Serdar Kiykioglu

Patent number: 6094480Abstract: A ring trip detector has a voltage difference detector with first and second inputs, for supplying an off-hook signal upon detection of a voltage difference. The ring trip detector also has a switch extending between the first and second inputs of the voltage difference detector. The ring trip detector detects when a telephone current starts to flow through a sensing resistor having first and second ends and to a telephone set. The switch closes upon an initial current flow through the sensing resistor and then opens. The ring trip detector has a pulse generating mechanism having two inputs respectively connected to the first and second ends of the sensing resistor. The pulse generating mechanism has an output and generates a pulse at the output when current starts to flow through the sensing resistor. The switch has a trigger connected to the output of the pulse generating mechanism for closing the switch when the pulse is generated. A differentiator mechanism may be used as the pulse generating mechanism.Type: GrantFiled: June 26, 1997Date of Patent: July 25, 2000Assignee: Fujitsu Network Communications, Inc.Inventors: Peter Vaclavik, Tsuyoshi Ueshima, Serdar Kiykioglu, Mark Bolla
