Quick question, I have a Cisco MC3810 with IOS 12.1. I just installed a T1/E1 Controller card which is recognized at startup as an E1 device. I want to use this as a T1 am I missing something? I have wiped the config ..etc started fresh always it comes up with:
Slot 3 OK. Configured as E1 TEB Serial #22588792 Version 7.03
This is both a T1 and E1 card right? Do I have something that is forcing this to go E1?
