HAPPY NEW YEARS
if you just want to use ITSP accounts over a 'net connection then you might be better off using no additional hardware in your asterisk box and using external ATAs instead, e.g. LinkSys PAP2, to provide FXS interfaces for normal analogue phones.
you can also use external boxes (e.g. Sipura SPA-3000) to provide an FXO interface, i.e. connect to your PSTN line, but i would always advocate using the Digium or Sangoma hardware. you can use the much cheaper clone X100P cards, but YMMV.
there are some “modems” you can use … but i’ve never tried. there aren’t many.
In this case I have to connect trhought Asterisk network interface any ATA that are connect to a analogue phones,right?

hi,
try to distinguish between phones and lines for me 
the card on the link you provided is for connecting your Asterisk box to a PSTN line. it’s also more expensive than i’ve seen elsewhere.
if you want a PCI card that has more than 4 FXS interfaces (for connecting analogue phones/handsets to) then look at the Digium TDM2400 option. digium.com/index.php?menu=pr … t=TDM2400P
there are external devices available that provide more than the “usual” 2 FXS ports, use the wiki at voip-info.org/wiki/view/VoIP+Gateways
Thank’s a lot for your patience whit my bad English and my bad ability.
Now I know that for my analogue phone I need a FXS port … 
I have see that whit a TDM400P card whit 4 FXS interfaces I can plug 4 phone,can I use 2 or 3 TDM400P card in the same asterisk box?
In my case the FXO interface will be a network card,all the analogue phone will use a VOIP.
I try to give you a diagram…
|Sip server|–ADSL–|My router|-- NAT–|Asterisk|–TDM400P/FXS–|phones|
It’s right?
I have see that a TDM400P is very expensive they are other way?
Thank’s
