E1 is only 2048000 bits/second if you never send 5 > consecutive 1 bits. The actual data rate on an E1 is in fact variable To the best of my recollection, the line bit (symbol) rate is fixed at, ideally, 2048000 bps. At least with HDB3 line coding, a sequence of 4 consecutive zeroes is replaced with three midscale values one the line, and a mark that violates the normal mark alternation scheme. I.e. 1,0,0,0,0 might be replaced with +,0,0,0,+ Thus, the "payload" data rate of 2048000 equals the line symbol rate of 2048000 symbols/sec. (Of course, this isn't really the "payload" data, since it includes the framing slots and all that, but...)
