Of course that can be done. But what would be more interesting is to send IP packets across ISDN and only pay when you send one, not when the line is idle. That is not simply a matter of putting ISDN bits in IP packets at the CO, because you don't know which bits are IP packets and which bits are just unused. (in theory, of course. when you define a framing protocol and put routers at the CO, the problem is solved. but I don't think that is currently done) Rob -- +------------------------------------+--------------------------------------+ | Rob Janssen rob@knoware.nl | AMPRnet: rob@pe1chl.ampr.org | | e-mail: pe1chl@wab-tis.rabobank.nl | AX.25 BBS: PE1CHL@PI8UTR.#UTR.NLD.EU | +------------------------------------+--------------------------------------+
