Filed:

Jul 31, 2006

Appl. No.:

11/461292

Inventors:

Jaspal Gill - Danville CA, US
David Keith Owen - Livermore CA, US
Troy Sheets - San Francisco CA, US
Daniel Lewis Kline - Fremont CA, US

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

H02J 1/00
G06F 13/00

US Classification:

307 31, 710100

Abstract:

A system may include a module that includes a component, a logic device to provide an instruction on behalf of the component, and control logic to generate a desired output voltage signal in response to a constant current, where the desired output voltage signal indicates a determined voltage that the component is configured to operate with when performing an operation. The system may include a board that includes a power supply to produce the determined voltage based on the instruction, and an interface to couple the determined voltage to the component to allow the component to perform the operation on behalf of the board, send the constant current to the control logic, and receive the desired output voltage signal from the control logic.

Appl. No.:

11/847659

Inventors:

Jaspal Gill - Danville CA, US
David Owen - Livermore CA, US
Thuan Che - Fremont CA, US

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

G05F 1/40

US Classification:

323288, 307139, 379412

Abstract:

A power system includes a switch, a capacitor and a comparator circuit. The power system receives a signal to turn off power supplied to the power system, turns off the switch that is used to supply power to the system and discharges the capacitor. The power system also compares a voltage across the discharging capacitor to a threshold voltage value, and turns on the switch to allow power to be supplied to the power system when the compared voltage across the discharging capacitor equals the threshold voltage value.

International Classification:

H02J 1/00
G06F 13/00

US Classification:

307 81, 307 80, 307 82

Abstract:

A device may include a plurality of direct current to direct current (DC/DC) converters that may produce voltages, and a first device that may receive a signal from a second device on a removable module when the removable module is coupled to the device. The first device may produce, based on the signal, an instruction related to one or more voltages associated with the removable module. The instruction may cause a first DC/DC converter and a second DC/DC converter, of the plurality of DC/DC converters, to power up at different times based on a particular sequence, and generate the one or more voltages. The particular sequence may be based on the signal. The first device may cause the one or more voltages, generated by the first DC/DC converter and the second DC/DC converter, to be provided to the removable module.

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

G05F 1/70

US Classification:

323207, 363127

Abstract:

An active voice-band filter includes a regulator to regulate an input current to the regulator and to convert DC voltage from an input bus to a higher DC voltage at an output of the regulator; an output voltage feedback loop, connected to the output of a regulator, for generating an output voltage value; and a current control loop for generating a control signal to regulate an input current of the regulator, where the control signal is based on an input bus current measurement and a reference voltage value. The reference voltage value is calculated using both of the output voltage value and an input bus voltage signal. The regulator regulates the input current to the regulator, based on the control signal, to reject voice band range current harmonics from the higher DC voltage.

US Classification:

370 85

Abstract:

A packet communications network and apparatus for communicating information in voice and data packets transmits and receives voice and data in accordance with standardized frames of a standardized communications format such as a standard DS-1 type trunk. An apparatus is coupled to multiplex standardized channels into a single channel wherein voice or data signals are packetized into independently addressable packets synchronized on, for example, the DS-1 frame. The network includes voice and packet data concentration apparatus operable in a multiple node trunk environment to concentrate signals into independently addressable synchronously switchable packets, thereby to provide an efficient (high data capacity) interface between trunk terminations. Up to four times as much information can be transferred between nodes with the ability to switch between nodes as compared to conventional TDM and PCM communication without compression without the ability to switch between nodes.
