US Patent:

61547972, Nov 28, 2000

Filed:

Aug 10, 1999

Appl. No.:

9/370978

Inventors:

William Burns - Boulder CO
Michael Lucas - Boulder CO

Assignee:

Storage Technology Corporation - Louisville CO

International Classification:

G06F 1300
H04J 322

US Classification:

710 52

Abstract:

A plurality of transmitters are multiplexed to a hub through clocked serial links. Timing problems that may arise when switching between links are eliminated with a system including a group serial receiver for each link for performing serial to parallel conversion of data sent over the serial link, outputing a group clock signal based on the serial clock signal, outputing parallel data clocked by the group clock signal, and determining a data enable signal from the serial link. A select signal for determining the serial link being read by the hub selects the corresponding group clock, parallel data, and data enable. A load control clocks the selected parallel data into a first-in, first-out buffer using the selected group clock when the selected data enable is asserted. When the selected data enable is not asserted, the load control is held in reset and, hence, is insensitive to irregularities in the selected clock signal due to switching between links. Data is clocked from the buffer by a local clock.

Inventors:

- Bethesda MD, US
- Richmond VA, US
Jerritt Hansell - Boulder CO, US
Michael Alan Lucas - Boulder CO, US

International Classification:

H04L 12/24

Abstract:

A system and methods for managing a transformer area in an electrical distribution grid having at least one substation transformer and one service transformer are presented. At least one Remote Hub governed by a policy may be provided, which collects data about the transformer area. The Remote Hub may also execute a discovery procedure to inventory Remotes in the transformer area. The Remote Hub may use the collected data to detect events, such as exceptional conditions, configuration changes, or derived results, within the transformer area. Based on the collected data, the Remote Hub is able to transmit data about the transformer area via a Substation-to-Edge channel. A method and system for forming and establishing boundaries of Transformer Area Networks is also presented. Discovery procedures may be used to form Transformer Area Networks out of Remote Hubs and Remotes powered by the same phase of the service transformer.
