Cisco Router - configure new T1 for point to point connection on two 1841 routers

Hello All,

I have two new 1841 series routers with integrated T1 CSU/DSUs int the router. I need to install each router a main site and branch site and connect the two. What commands do I need on the router to use the new T1s. As far as I know I just need the following. Am I correct? Do I need any special configuration at the main or branch routers for the T1? Thank you.

Main Site:

Interface Serial0/0/0
service-module T1 timeslots 1-24
ip address 172.21.175.1 255.255.255.252

Branch:

interface Serial0/0/0
service-module T1 timeslots 1-24
ip address 172.21.175.2 255.255.255.252

On which router do I need to set the clock source to internal? I know we have other sites and one router is set with service-module t1 clock source internal and the other is not. Also do I really need ppp encap?
