Cisco PIX 520/ VPN and Cisco VPN Client

Hi,

We are currently in the process of reviewing our
Cisco PIX 520 firewall and its VPN feature.
My question is:

Can we have users at a site with a T1 line for internet connection logon individually like at home using DSL, but instead using the same T1 line to connect to our Cisco PIX 520 with VPN.
The users will have Cisco VPN client installed and configured on each PC/laptop.

Thank You.
