Troubleshooting x2 Client Connections
Use the chart below to understand issues affecting your Courier modem and
how to fix them:
Step
This may be the issue
Do this
1
x2 may not be enabled
on your Courier.
See the section “How to Tell if x2 is
Enabled” (Use the ATI7 command)
2
Several conditions
may exist.
Use the ATI11 command and check the “x2
status” field for more information.
If this message
appears
You cannot use x2
because
“Multiple
CODECS in

There are multiple
analog-to-digital
conversions on the
channel.
“Remote modem
is not x2”
The remote modem
does not support x2.
“Channel is x2-
capable but
feature is not
installed”
You have not
purchased x2.

Your Courier may be
connected to the
public network via a
PBX or other
telephone equipment
with analog-to-digital
and digital-to-analog
conversions.
Contact your telephone equipment vendor
for information about obtaining pure
analog service.
Due to extra analog-to-digital conversions
performed by some PBX’s and other
telephone equipment, x2 client modems
may not be able to make x2 connections.
