Hi.. Dear all,
I don!&t understand this. Hope u can clear my concept. I have a 1700 router
in remote office(Milan) which is connected to a main router in London via a
Frame-relay link in interface s0.1. My IT colleague (Milan) told me that the
frame-relay line was cancelled last week by ISP!&s mistake and the link has
been running on ISDN since the 20th August. Until now it is still in ISDN.
Now I found that the Milan(remote) router is still connecting main router
via the same interface s0.1. When I type !'sh int s0.1!( shown below, it
still show me that it is a frame-relay.
1)How do I know whether it is on ISDN or not, what command?
2)What is the difference between frame-relay line and lease line. Can I
say that previously the line is a frame-relay leased line and now it is a
frame-relay ISDN line??
3)How can they change the line into a ISDN using the same interface? I
thought it should have a ISDN back up interface?? Can the ISP vendor change
the circuit to ISDN at their site without coming the Milan office? Or the
Remote(Milan) office change a ISDN!&s CSU/DSU and made it to a ISDN line?
