Multiple PSTN line support

Hi,

I am working on a proof-of-concept system for deployment of an Asterisk driven VoIP system at one site for my company.
I was hoping if one of you kind folks would be able to tell me if Asterisk supports multiple PSTN lines?
If so, is this best done via multiple FXO cards or can I simply order a dual channel fax modem and use that? Or is there another way?

Cheers,
Matt.

Solved I guess. Going to just use a TDM range card with an FXO module.
