DATA TRANSFER DEVICE Russian patent published in 2006 - IPC H04L9/00 H04L9/12 H03M5/16 

FIELD: data transfer devices for synchronous communication systems.

SUBSTANCE: proposed device has data transmitting and data receiving units connected to opposing ends of communication line. Data transmitting unit has stuffing unit and scrambler; data receiving unit has descrambler and destuffing unit. Device is characterized in that data transmitting and receiving units are capable of simultaneously identifying definite codes in bit stream which are shaped into random (unknown in advance) time moments. These moments function in the first place as reference points in sorting out bits assigned to different channels and are used, in the second place, for synchronous setting scrambler and descrambler pseudorandom bit sequence generators to same states. In this way service bits for stream division among channels and service data frames designed for code synchronization of descrambler and scrambler are excluded from data stream.

EFFECT: enhanced data transfer speed.
