Referring to the subject, U-Interface card has a built-in NT1 and uses a RJ49C connector. S/T-Interface card is used by connecting to an external NT1 and uses a RJ45 connector. Hence, just to confirm if I can use U-Interface card and connect to an external NT1 using normal RJ45 cable?
I am not familiar with ISDN BRI and was given this task to upgrade from an older Cisco router to a new Cisco 1941 with ISDN BRI U-interface card. Looking at the current configuration I have below, I'm just wondering whether it is correct? How come no dialer for it?
Appreciate your kind feedback on this.

Thanks for sharing. As per the current/old setup, over at HQ, it is running on Cisco 1603 and connected to an external NT1. So, there' s no way to eliminate the use of the external NT1, correct? And I need to use a S/T interface here?
However, at the Branch, there's a Zyxel ISDN router which connect directly to telco jack. Hence, any idea on how to confirm if I should use a U or S/T interface?
Also, it will be great if you can advise me on the configuration part too. I saw online that usually they're using a dialer interface, but in this old configuration, only can see the configuration on the BRI0 interface. Any ideas?
