Class Information
Number: 370/504
Name: Multiplex communications > Communication techniques for information carried in plural channels > Combining or distributing information via time channels > Synchronizing > Reference indication consists of a gap
Description: Subject matter in which synchronization is achieved by identifying the absence of data transmission for a predetermined interval (i.e., a gap) and using that absence to identify a reference point within a transmission interval.
