[vcf-midatlantic] Minimum requirements for receiving 56K modem connections

Hi folks!
I'm messing around with a bunch of modems at home, and would like to know
what's required to set up one system to receive 56K calls from another
system.
I'm able to get 33.6kbps bi-directionally (or 31.2K) with just a phone line
between the two modems, and using ATX1D and ATA commands.
I think to get 56K I require some equipment to simulate a digital
connection, and I'm also not sure if a 56K analog modem can even receive
56K calls. Is this true?
Modems I have on hand:
- a USRobotics Courier I-Modem
- 2 x USRobotics V.Everything, and a USRobotics 56K/X2 Sportster external
modem
I am also unable to get the I-Modem to connect to any of the analog modems,
and although it does have the protocols to support analog, it seems like
it's expecting a BRI / ISDN connection to allow that connection. Is this
true?
If the above are true - what's the minimum / cheapest solution for being
able to at least establish a V.90 connection given the equipment I have
already?
Thanks for your help!
John
