Susan, Some ways to check if your ISDN is connected are: 1. show dialer Output should look similiar to this: Router #show dialer interface bri 0 BRI0 - dialer type = ISDN DIAL String Successess Failures Last called Last status 0 incoming call(s) have been screened. BRI0: B-Channel 1 Idle timer (120 secs), Fast idle timer (20 secs) Wait for carrier (30 secs), Re-enable (15 secs) Dialer state is data link layer up Dial reason: ip (s=6.1.1.8, d=6.1.1.1) Interface bound to profile Dialer0 ********* Pay attention to this area of the output**** Time until disconnect 102 secs Current call connected 00:00:19 Connected to 5773872 (system1) ********************************************** BRI0: B-Channel 2 Idle timer (120 secs), Fast idle timer (20 secs) Wait for carrier (30 secs), Re-enable (15 secs) Dialer state is idle Also look at your interface itself. If the ISDN is active, the interface will show UP/UP. Rather than UP/DOWN or UP/UP/SPOOFING, depending on how you have the interface configured. Here is a good link on the Cisco web page, that has configuration tips, troubleshooting, etc. http://www.cisco.com/warp/public/471/index.shtml#isdn Good Luck Debbie --- Farhan Ahmed wrote: > 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..
