Difference between ISDN,Frame Relay,Site to SIte VPN, PPP,HDLC
I need some to clear up the confusion between the connection stated in the Title above.
If I understand a little bit :
Site to Site VPN,PPP,HDLC can connect through DSL to internet and communicate with other side.
for the Frame Relay, the FR provider connects you through FR switch on his side , and you will use specific hardware to connect you serial interface to the FR switch.
ISDN has a port that looks like RJ45 but larger, I am not sure where it will connect to, and if the provider will give you DLCI/PVC/CRI just like FR.
THANKS

I was asking about physical connection , end to end.
for instance , Site to Site VPN, you need to plug the Cisco router external interface to DSL modem and configure the Tunnel. This is done on both ends.
I am not sure about:
ISDN,Frame Relay, PPP,HDLC, how physicall they get connected end to end

I meant , for instance site to site vpn:
you plug the cisco router external interface to DSL modem RJ45 in one side and do the same in the other side. and all there is between 2 sites is the Internet cloud.
How do you connect 2 or more sites in order to use HDLC,ISDN.PPP,Frame Relay.?
are there any specific interface on the routers.?

F/R doesn't require any special hardware on the customer side.
ISDN is basically a circuit switched (dial-up) point-to-point service.
