This documentation is for eagle-usb driver, for ueagle-atm driver (since kernel-2.6.15) check
http://atm.eagle-usb.org/wakka.php?wiki=DocEagle4InfoCMV too which show how to use buildcmv (included in svn tree).
In
Dev:EagleUsb200 (interwiki), with Sagem and Analog help, we have added the implementation of CMV to simplify the configuration of the modem.
See
Dev:ConfigFiles (interwiki) for some more details (both french / english...). Try latest version of driver
Dev:EagleUsb220 (interwiki)
What are CMV ?
- CMV means Command Management Variables
- The values in /etc/eagle-usb/CMVei.txt and /etc/eagle-usb/CMVep.txt respectively for ISDN and POTS lines provide a simple way to send parameters to the modem
- the dsp_code*.bin files implement the code executed by the modem to connect to your ISP's DSLAM
- some more documentation is available thanks to ADI (pdf + Excel file) : http://baud123.free.fr/eagle3/ADI_DOC/EagelUsbDoc_041205.zip (~ 900 kB)
How to configure CMV ?
- either you put them in /etc/eagle-usb/eagle-usb.conf or you compile the driver with the option ./configure --enable-cmvs (they should appear in only one place) See Dev:EagleUsbIII (interwiki)
- the following values are valid
- do not try to change these values, your connection may not work anymore
- Only VPI / VCI / Encapsulation have to be changed according to the values given by your ISP or in this table
- Change Linetype to 0x0A (in hexa, 10 in decimal) : well, just replace the 1 with an A ;-)
- /etc/eagle-usb/CMVe{i|p}.txt should be a link to the appropriate /usr/share/eagle-usb/CMVe{i|p}${ISP}.txt
See
http://cvs.gna.org/cvsweb/eagleusb/driver/user/?cvsroot=eagleusb for generic CMVs used for several ISP.

In case your websurf seems slow
- just comment option 1 :
- the line for OPTN1 (adding a # at the beginning of line in /etc/eagle-usb/eagle-usb.conf)
- or the line cw optn 1 (adding a ; at the beginning of line in /etc/eagle-usb/CMVep.txt)
- we do not know what this option means and how it interacts with the DSLAM, maybe it depends on your ISP's equipment ?
Change the modulation standard
The "cw OPTN 4" stands for :
- cw optn 4 0 -> ADSL MULTISTANDARD
- cw optn 4 2 -> ANSI T1.413
- cw optn 4 11 -> G.DMT
- cw optn 4 21 -> G.LITE
We currently have :
CMVei.txt CW optn 4 00000001
CMVep.txt cw optn 4 0x00600000
CMVepES.txt cw optn 4 0x08600002
CMVepFR.txt cw optn 4 0x00600000
CMVepIT.txt cw optn 4 0x006c0000
Change synchronization throughput
To force modem to synchronize at 8032 kbps, put value 0x02fb0000 for OPTN7 (0xfb x 32 = 8032).
This limit of 8032 kbps is due to the use of ISO mode for downstream data.
Here all values for Cegetel ADSL Max :

Tips
il est possible de savoir si l'on utilise un modem POTS ou ISDN en lisant le 16ème octet de l'EEPROM (octet 15). C'est ce qui est fait avant l'envoi du DSPcode au modem.
POTS = 0x0B
ISDN = 0x8B
Vocabulary
- CMV : Command Management Variables
- DSLAM : Digital Subscriber Line Access Multiplexer
- ISDN : Integrated Services Digital Network (called Numeris in France)
- ISP : Internet Service Provider
- POTS : Plain Old Telephone Service (corresponds to analogic lines)
