Understanding the Issues/
Troubleshooting Problems
Testing has shown that a vast majority of analog lines in the U.S., Europe and the
Pacific Rim will support x2, but certain conditions in the network or the local loop may
prevent x2, either intermittently to a certain destination or at any time from certain
analog lines.
This paper explains the circumstances under which x2 speeds cannot be achieved and
gives troubleshooting advice. It is intended to help the majority of customers whose lines
can support x2 speeds and to impart an understanding of why a small minority cannot
achieve x2 speeds.
Expectations
Currently, due to restrictions set on the output power allowed in the U.S., Canada and
other countries, the maximum speed is bounded at 53.3 Kbps. Support for 56 Kbps (and
above) is contained within the code, but server code being shipped today is restricted to
53.3 Kbps. U.S. Robotics and others are endeavoring to have these regulations
modernized, so this restriction may be removed in future releases.
Certain line conditions and network configurations also produce impairments that may
restrict the actual rates achieved, with x2 just as with V.34 (and V.34+). As of today, the
majority of users are probably finding their connect rates in the 46-48 Kbps range. Very
few (we believe less than 5 percent) will not achieve x2 speeds at all. This paper is
intended to help the 95 percent get x2 running as it should, and to impart an
understanding of why those 5 percent do not achieve x2.
It should also be understood that there will be continuous improvements made to the
code, and it is quite possible, if not likely, that future code releases will increase
performance and reduce the occurrences of x2 not functioning in certain environments.
Requirements
x2 requires the following:
1. A digital connection at one end.
One end of an x2 connection must terminate at a digital circuit, meaning a "trunk-side"
channelized T1, ISDN PRI, or ISDN BRI. Line-side T1 will not work because an extra
analog section is added. In a trunk-side configuration, once the user’s analog call is
