• MP I-modem or NETServer I-modem with x2
Making x2 Work
To use x2, the x2 client modem must connect to an x2 server modem.
If clients attempt to connect to ISPs that do not use x2, the client
modem will negotiate the next available modulation. For example, an
x2 client modem calling into an ISP that only supports V.34, will
negotiate the highest V.34 connection rate. The maximum V.34
connection speed is 33.6kbps.
When an x2 client modem connects to an x2 server modem, the path
through the telephone network between the modems is subject to the
following conditions for an x2 connection to be made.
A Digital Connection At One End
ISPs or online services must have a digital connection to the PSTN.
Most major online services have digital connections to the PSTN.
Only One Digital-to-Analogue Conversion
There can be only one digital-to-analogue conversion in the telephone
network between the x2 server modem and the x2 client modem.
