Usage of PPP protocol

per the link below:

 PPP is used for internet communication between customers and providers.
In Cisco Labs , I managed to configure PPP between 2 cisco routers, I am not sure how providers configure PPP at the customer end ?
Any EE to shed light on this ?

Either ISPs preconfigure the router/modem to contain the necessary data, or they provide instructions how to do so. There are also protocols for remote maintenance of some devices, which an ISP can use to remote configure it.

is PPP used as WAN connection between 2 sites of the same company?
I mean instead of using Frame relay or MPLS, or site to site VPN, can they use PPP ?
I heard also about ISDN...
a Lot to know about these confusing technologies (:)

No, PPP is not used for a connection, it is a negotiation protocol, supplying subprotocols like PAP (authentication), IPCP (IP parameter exchange), compression, multilink, and many more. So PPP allows to establish a connection. What happens after the connection is established is no longer under control of PPP, until the connection gets closed gracefully.

Sorry for the delay...I was busy with other things....
If I understand PPP is a protocol, but what are the specific medium is configured on ?
you mention ISP modem that they deliver to home users is configured with PPP.
What about companies when do they use it ?

Thanks again

It is also part of e.g. PPTP, and used with ISDN data connections. And there are certainly other physical or logical connection media. So it used in companies.
