1. If a multicode stream is transmitted at a rate of 80 KB/S, this means that the information traffic in multicode symbols is 80,000 bauds per second. If a multicode, such as a quadratic code (22), is converted to binary to measure it, then the information bit traffic is 80X2=160 Kb/S.

2. The bandwidth may also be only a theoretical value, rather than an actual rate of transmission. . In reality it should be slower.

Not sure, just for reference.
