It would have been difficult (expensive) for a BBS to support 56k. The calling side modem could be on an analog POTS line, but the called side needed a digital circuit, usually a PRI (T1 with ISDN signaling.) It was far easier for them to support 64/128kbps ISDN -- all they needed was one or more dual-channel BRI lines.
