US Patent:

H18147, Nov 2, 1999

Filed:

Feb 19, 1998

Appl. No.:

9/026321

Inventors:

Mark David Browning - Bartlett TN
Cecil W. Johnson - Memphis TN
Scott Arthur Kooy - Memphis TN
H. John Lohn - Collierville TN
Shawn Wayne Vines - Bartlett TN
R. Timothy Wallace - Bartlett TN

International Classification:

H04M 100
H04Q 720

US Classification:

379242

Abstract:

A telephony-support module capable of responding to heartbeat messages and identifying itself as operational over one bus or both buses of a redundant-pair control bus. The module also has a reprogrammable, nonvolatile memory associated with it from which the module can run its operating system. The module can also transfer the operating system into another memory, allowing it to make updates to the operating system stored in the nonvolatile memory without interrupting its execution of its run-time operating code.

US Classification:

379 9

Abstract:

A switching module capable of sending heartbeat messages and identifying other elements within a telecommunications switching platform as operational over one bus or both buses of a redundant-pair control bus. The module also has a reprogrammable, nonvolatile memory associated with it from which it can run its operating system. The module can also transfer the operating system into another memory, allowing the module to make updates to the operating system stored in the nonvolatile memory without interrupting its execution of its run-time operating code.

International Classification:

H04J 316

US Classification:

370465

Abstract:

Described is a system and method for transcoding and rate-adapting between information channels having a first rate and signal-encoding scheme and information channels having a second rate and second signal-encoding scheme. Further described is a system and method for determining when a signal-processing module has failed or been removed or inserted into an operating telecommunications switching platform. Also described is a system and method for efficient power-up, to allow for more efficient system power-up, the signal-processing modules of the present invention preferably have their operating systems stored in a nonvolatile memory that can be reprogrammed without removing it from the system. A switching module is further capable of responding to heartbeat messages and identifying itself as operational over one bus or both buses of a redundant-pair control bus. The module also has a reprogrammable, nonvolatile memory associated with it from which the module can run its operating system.

US Classification:

455560

Abstract:

An interface module capable of responding to heartbeat messages and identifying itself as operational over one bus or both buses of a redundant-pair control bus. The module also has a reprogrammable, nonvolatile memory associated with it from which the module can run its operating code. The module can also transfer the operating code into another memory, allowing it to make updates to the operating code stored in the nonvolatile memory without interrupting its execution of its run-time operating code.
