Hardware connection to PSTN

Sorry I forgot.

When using Asterisk on a small server / PC as a PBX replacement.

  1. What hardware do you need to connect to the PSTN? ie card, cables etc.
    if a) standard telephone socket with broadband (ie at home end)
    or b) ISDN or other connection at small business end.

Alternatively if you have a VOip supplier to get out into the PSTN can you just use your LAN/WAN connectivity?
