CLU is the current line utilization. It's the percentage of the
total bandwidth being used.
ALU is the average line utilization. It's the percentage of the
average bandwidth used.
The calculation of these values depends on rather the link is to
a remote node or dial in user. If the link is to a remote node,
it depends on what is choose in Menu 11.2, Remote Node PPP
Option, for BOD Calculation. If the choose is Receive, then CLU
and ALU represent only the incoming traffic. If the choose is
Transmit, then they represent only the outgoing traffic. If the
choose is Transmit or Receive, then it represents whichever
traffic is greater. Dial in user links always calculate as
Transmit or Receive.
Why is remote node calculation so complicated?
Because it's also used for bringing up the second channel.
So, if you set you Target Utility as 32-48Kbps and the connection
speed is 64K, then the second line will be brought up if the CLU
reaches 75% and the second line will be dropped if CLU drops to
50%. ( Note, the CLU has to maintain that level of usage for the
specified persist time before the second line is brought up or
dropped. )

How do I setup Compression to work with Ascend?
Ascend supports 2 styles of Stac compression. One is their
proprietary stuff that was implemented before CCP standard was
finalized. For unknown reasons, they did not request it to be
included in the standard. The other is what they call "MS-Stac",
which is actually check mode 4 in the standard. D-Link does not
support their proprietary check mode. We support check mode 3
(sequence number) and 4 (extended mode, proposed by Microsoft) in
the standard.
If CCP negotiation fails, it could be 1. compression is off; or
2. compression is set to "Stac", instead of "MS Stac" in Ascend
MAX/Pipeline.

Miscellaneous Questions
1.
How can I tell what version of system code I have?
For the RAS software version: see menu 24.1
For the ISDN firmware version: see menu 24.1
For the bootmodule version: see the screen during system startup

How can I upgrade system code?
The SMT (System Management Terminal) has an option (Menu 24,
option 7) that allows you to easily upgrade the system code.
Once you execute this option, you can follow the onscreen
instructions to upload the system code. You will need to invoke
XMODEM to download the code. For a more detailed description of
