Limiting The Lowest Possible Connect Speed; Setting A Range Of Possible Connect Speeds - US Robotics x2 Courier I-modem Manual

Limiting the Lowest Possible Connect Speed

The &U command allows you to limit the lowest possible connect speed. If a
remote modem connects to your Courier I-modem with x2 at a speed lower than
&U, your Courier I-modem with x2 will not allow it to connect.
To limit the
Lowest possible connect speed to 48000

Setting a Range of Possible Connect Speeds

By setting &N and &U values, you can limit the range of speeds at which your
Courier I-modem with x2 connects. If a remote modem does not connect to
your Courier I-modem with x2 at a range between the speeds designated by the
&N and &U commands, your Courier I-modem with x2 will not allow it to
connect.
Note: The link speed associated with the &U argument cannot be greater than
the link speed associated with &N argument.
Use the following table to understand the relationship between &U and &N
commands:
If &U
Equals zero
Is greater than
zero
8
x2 Addendum
And &N
Equals zero
Is greater than zero
Is greater than zero
and greater than &U
Use this command
&U=24
Then your I-modem
Connects at the highest possible
speed.
Connects at the &N speed only.
Connects at the highest possible
speed in the range from &U to &N.
