Stuart- Boot up in ROMMON and tftp a newer version of IOS. Short of that, Call TAC for a replacement ISDN WIC or a replacement Router.
My reason for booting up in ROMMON is to insure the code for the WIC doesn't get loaded, ensuring no interruptions while trying to upload the new IOS. What version of IOS are you running? I had a 1720 recently (was brand new) that kept having problems with bonding both channels in a MPPP setup to the ISP. Turned out the IOS was the problem, which if I recall, was something like 12.2.4. I upgraded to 12.2.8T5, and the problem went away. -Mark -----Original Message----- From: Stuart Laubstein [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 19, 2002 8:53 AM To: [EMAIL PROTECTED] Subject: 1720 ISDN problem [7:53616] I am having a curious problem with a 1720. When I enable the BRI the router reloads ist config and locks me out of telnet as well. I changed the config and saved but when I stuck the isdn cable in it reset the config to the old one. Any ideas on what I can try here? thanks stuart Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=53624&t=53616 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
