Appl. No.:

12/260514

Inventors:

Daniel Biederman - San Jose CA, US
Dennis Fahey - Oakland CA, US
Hugh Barrass - Milpitas CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G08C 17/00
H04J 3/06
H04L 7/00
G06F 1/00

US Classification:

370311, 370350, 370503, 375354, 713300

Abstract:

In one embodiment, a method includes receiving a synchronization command to synchronize time information among each component of a set of components in a communication path. The method includes generating a power state message. The method includes transmitting the power state message, by the first component, to the remaining components in the communication path. The power state message is configured to reduce the power consumption of the remaining components of the set of components from a first power amount to a second power amount for a time period and the time period is associated with the synchronized time information.

International Classification:

H04J 116
H04J 314

US Classification:

370246

Abstract:

A stack position determination circuit in a stackable repeater is disclosed that includes an input connector, an output connector, an initial pin driving circuit, and a pin rotating circuit. The input connector includes a plurality of input connector repeater stack position pins arranged in an hierarchical order so that each input connector repeater stack position pin corresponds to a possible physical position of the repeater in a stack of repeaters. An output connector includes a plurality of output connector repeater stack position pins arranged in an hierarchical order so that each output connector repeater stack position pin corresponds to a possible position of the repeater in a stack of repeaters. An initial pin driving circuit is connected to an initial pin in the input connector repeater stack position pin hierarchical order. The initial pin corresponds to a first position in the stack of repeaters and the initial pin driving circuit is responsive to an initial repeater signal.
