2600 router's ethernet port is connected to which device? Is it to a Catalyst switch or something? Because on few catalyst switches there is something called "errdisable" ( Error Disable ). What it does is that it will disable a specific port if it detects too much of collisions, mismatch in duplex configuration, too many errors on the port due to layer one issues etc. So, I would suggest you to check the ethernet cable on 2600 that connects it to the LAN, check the port status on the switch (assuming it is a switch) etc. May be it is worth to check out the following URL
You may wand to "nail down" the speed and duplex of the ethernet port. Also when the interface shuts itself down you may want to telnet into the t1 interface and do the show proce cpu and mem commands see what's up with that. You might want to also capture a show tech for cisco to look at.
don't know about the dispose ip.hopcount messages but my bad on the speed deal. If it is a 10 mb card it will not have a speed command only duplex. To clarify nail down both sides of the ethernet to 10 half or 10 full.
