Class Information
Number: 370/523
Name: Multiplex communications > Communication techniques for information carried in plural channels > Combining or distributing information via time channels > Signaling (ancillary to main information) > Using bit robbing
Description: Subject matter wherein a bit which is normally used to convey main information is temporarily used for supervisory information. (e.g., the 8th bit of a byte of information is temporarily used for signaling).
