The present invention provides a method for conveying information over a communication network such as a Digital Loop Carrier (DLC) network free of in-band signaling information for at least a portion of an established communication between at least two users so as to reduce the information error rate associated with the established communication. For communication links that support robbed-bit signaling (RBS), the RBS signaling is disabled to allow the communication link to be operated in a clear channel mode. When appropriate, operations can be switch from the clear channel mode back to the RBS mode. Embodiments are described for one-stage DLC systems having a local digital switch (LDS) connected to a remote terminal (RT) by a communication link conforming to either the TR-303 protocol or the TR-008 protocol. In addition, embodiments are described for two-stage DLC systems that also have a distance terminal (DT) connected to the RT by a second communication link.

Voice frequency data enhancement method

A computer system comprises an active processor and one or more spare processors. A dummy thread is created on the active processor while the active processor is running a current thread, causing the current thread to become dormant. The operating system of the active processor saves a set of internal state information for the current thread into a first memory coupled to the active processor. Each write to the first memory is duplicated in an equivalent spare memory coupled to each of the one or more spare processors. The dummy thread then activates the spare processor and de-activates the active processor.
