Can a router be configured to look like ISP?

Talk about anything you like here: as long as it's technical, doesn't fit into the other categories and is within the rules. Questions and discussions about operating systems, programming, websites, hosting, ADSL etc. are particularly welcome here.

Can a router be configured to look like ISP?

Hi router people,
I didn't know where to put this.
Please be nice - I know nothing - but I'm hoping to learn.

Firstly is the RouterTech firmware completely open source?
If not which bits are not? I've heard that TI hasn't released the AR7 code, but according to the MIPS people the complete code can be collected from the bits and pieces in the various GPL released code.

Secondly, has/could this be done:

LAN > modem/router 1 > single pair > modem/router 2 > ethernet: pseudo WAN > modem/bridge 3 > WAN

This would allow the examination of packets on both the WAN and LAN side of modem/router 1, which is being tested.
In a previous network layout I had a router and a separate authenticating bridge to the ISP, and looking at both sides of the router was very useful for troubleshooting.
But with an all-in-one the only way to find out what you are actually sending is to hassle the ISP, and after being on hold for several hours they may not help you.

As far as I can tell, line negotiation and how DSL channels are used is all done in software. So it ought to be possible to set router 2 to pretend to be an ISP.
