Method and apparatus for sanitizing a memory using bit-inverted data. A logic core to perform pixel fragment manipulation and processing is instantiated on a single substrate with one or more memory units. The interactive request server program may optionally be implemented using a web server program and an application server program, with the web server program interfacing with the client computers via an Internet-type interface, and the application server program interfacing with the timing analysis program using a programmatic interface supported by the timing analysis program. A second set of inductors are electrically coupled with the first set of inductors in a parallel fashion. In addition, the fallback detectors detect the failure of the PBX to respond when a telephone is used to attempt to make an outgoing call or a call to another one of the local telephones.
