Configuration for a Cisco 3825 with NM-1T3/E3

Hello Experts -

My company is utilizing 20 Mbps of a DS3 that comes into the building on a fiber OC3 channel.  We purchased a Cisco 3825 router with a NM-1T3/E3.  I've configured similar routers for bonded T1s via Multilink PPP but have never dealt with a DS3.  I have been looking for a generic configuration example but haven't had much luck.  Can anyone help?

Thanks in advance.

This really really depends on what you need to put on that DS3
but here goes

interface Serial1/0
 description DS3 to XXXXX (CktID:xx/xxxx/xxxx)
 ip address
 max-reserved-bandwidth 100
 service-policy output VOICE_QOS (You probably won't need this either)
 framing c-bit
 cablelength 10
 dsu bandwidth 44210
 clock source internal
 serial restart-delay 0

Thanks memo and ciscom!  I had to split up the points.  The link was helpful but it wasn't a NM-1A-T3/E3 (ATM); rather, it is a clear channel DS3 using a serial interface but it did point me in the right direction.  I used some other Cisco references and my configuration is very similar to the one ciscoml320 posted.

Couple of questions...what do the following commands do?  I don't have those in my configuration.

max-reserved-bandwidth 100
serial restart-delay 0

Thanks again.
