[Asterisk-Users] fxotune error

[Giorgio Incantalupo]

Hi,
I have an asterisk 1.2.1 on a debian box with a tdm400p card and a 
monoBRI card.
I tryed to use fxotune: turned off asterisk leaving modules active as 
seen from lsmod:

zaptel                224132  1 wctdm
crc_ccitt               2432  1 zaptel

I launched fxotune:
*pbxtest:/etc/asterisk# /usr/src/zaptel-1.2.1/fxotune -i 4*

but fxotune displays these messages:

*Tuning module 1Skipping non-TDM / non-FXO
Failure!
Could not fill input buffer
Tuning module 2Failure!*

What does they mean??

TIA
