Hi,

I have a Cisco 4000 router with 4M flash/16+4 RAM with
two * NP-4T cards. Serial 2 & Serial 6 ( 3rd port on
each of the card ) on this router works fine for about
20-30 minutes. after that the link/line protocol
bounce up and down, then it goes down completely. I
tried both Frame-Relay and HDLC encapsulation as well
as lowing the clock rate to 56000 and 64000.

Has anyone cames across same or simular kind of
problem ?
The router is running 12.0(15) IP/IPX/AT/DEC Plus
feature set.

Any help/suggestions will be appricated

Thanks in advance

Charles
