i think they put a ta on serial interface and change the layer 2 to isdn instead if u dont have a isdn interface -----Original Message----- From: Susan Stone [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 29, 2001 1:06 PM To: [EMAIL PROTECTED] Subject: please clear my concept on frame-relay and ISDN [7:17649] 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?
