Filed:

Sep 23, 2003

Appl. No.:

10/669192

Inventors:

Paul B. Ripy - Guerneville CA, US
Keith Q. Chung - Durham NC, US
Gary J. Geerdes - Santa Rosa CA, US
Christophe P. Leroy - Rohnert Park CA, US

Assignee:

Tellabs Petaluma, Inc. - Petaluma CA

International Classification:

G06F 13/00

US Classification:

710113, 710107, 710240, 710244

Abstract:

Access to a bus is granted to one of a number of requesting communication circuits that each submitted a bus control request during a request period of an arbitration period in response to the entries in a priority table. If a requesting communication circuit has an identity and priority that match the identity and priority of a communication circuit stored in a row of the priority table that corresponds with the arbitration period, access to the bus is granted to the requesting communication circuit.

US Classification:

711200, 711151, 711156, 711168, 711169, 718103

Abstract:

A scrambling operation is used to space apart the grants that a communication circuit receives during a period of time, such as 512 arbitration periods. An operator can enter the number of arbitration periods that a communication circuit is to receive in blocks of sequential logical address ranges. The logical addresses are then changed to physical addresses that are spaced apart, thereby significantly reducing the buffering required by the communication circuit.

Abstract:

A method for paying back customers for unused service units remaining after a billing cycle. A payback amount is determined by the product of the number of unused service units remaining and the payback rate amount. The payback amount credited to the customer is the calculated payback rate or a maximum payback amount, wherever is smaller. A total payback amount can be determined based on a combination of payback amounts for various services, including voice services, texting services, email services, and/or data storage services.

US Classification:

710107000

Abstract:

Access to a bus is granted to one of a number of requesting communication circuits that each submitted a bus control request during a request period of an arbitration period in response to grant information which can be stored in a primary and a backup priority table. If a requesting communication circuit has an identity and priority that match the identity and priority of a communication circuit stored in a row of the primary or backup priority table that corresponds with the arbitration period, and the identities stored in the tables match only one requesting communication circuit, access to the bus is granted to the requesting communication circuit.

International Classification:

G06F 11/00

US Classification:

714006000

Abstract:

An input memory circuit, which has a plurality of addresses that have an associated plurality of keys, forwarding information, and enable/disable flags, receives a plurality of input cells, extracts key information from each input cell, compares the key information from each input cell with the keys, and outputs forwarding information for an input cell when the key information of the input cell matches a key at an address and the address is enabled.
