DEFINITION

Classification: 370/503

Synchronizing:

(under subclass 498) Subject matter including a means for insuring that the transmission and reception of time multiplex information has a proper time relationship.

(1) Note. Included herein is a phase locked loop synchronizer unique to multiplex and a system analogous to pulse stuffing or deletion which utilize a guard interval but do not stuff or delete, but rather adjust timing to prevent conflict.

304, for a synchronizer in a low speed asynchronous data system.
