Abstract
The transport of ABCD bits in a digital packet network is facilitated by the inclusion of the ABCD bits into the RTP header of the digital packets. The ABCD bits are first placed in the unused bits of the RTP header. Redundancy of the previous ABCD bits, when applicable, is achieved by restricting the size of fields in the header to reserve space for redundant ABCD bits. The ABCD bits are placed in the reserved portions of restricted header fields.
