Configure HWIC-1DSU-T1 for Qwest T1

Greetings.  I just got a 1921 and I will be connecting it to a T1 provided by Qwest in a few weeks.  I wanted to prepare for this deployment as much as possible.  They have not given me any public IP addresses yet.  Can someone take a look at the config snippet below and tell me if I am headed in the right direction?  Thank you.

Interface serial 0/0
service-module t1 clock source line
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs
ip address x.x.x.x 255.255.255.252
encapsulation ppp
no shut

You likely will have external clock. Ask.

b8zs and esf are default.

common mask on ptp is /30

That's it.

Yeah the second line should read "service-module t1 clock source line".
