C9 Network CMTS firmware

Hello,
I have get an old C9 Networks C600 CMTS for make lab.
I have also get any nessesary parts (diplex filter, athenuator, ...)

Note: My cable modem found "energy" but don't decode signal (eurodocsis modem)

My version of this cmts has "DOCSIS" firmware and seems to not support EURODOCSIS.
If i look on cmts datasheet, eurodocsis is supported.
Anyone has eurodocsis version of c9 c600 firmware ?

Sorry for my bad english.

Thanks for help

Best regards
Cédric R
