Whether you are talking about X2 or K56plus flavors of 56K modem they come in two types, one for the server end that answers calls and one for the client end to originate calls. You cannot hook two client 56K modems together and get anything faster than v.34+ out of them. In fact, in some recent field trials USR had difficulty getting faster than 53K out of their X2 modems. This is not a silver bullet technology. This is living on the bleeding edge; that's the thin edge of the razor's wedge. Everything has to be perfect or it just won't work.
