How to Configure a Cisco Router to a Standard T1

Hello Everyone,

I am in a bit of a pickle. I am halping out a friends company with implementing a T1 connection through Cavtel. We purchased the equipment that Cavtel suggested a 1721 router and a CSU/DSU T1 WIC. We installed this and started to configure it to Cavtel's specs and we are unable to get even basic network connectivity to the internet. What i mean by this is from interfacing with the router through telnet i can ping the LAN port and can Ping the WAN port. I can not Ping the DNS they provided me or any common internet IP addresses. When my first attempt out of the box did not work i looked on here to see if anyone else had the same problem and found one hit. I used some of the suggestions in the post to reconfigure the router but no luck.

Below I am going to put the configurations they told me to use and a sh config from the router. If anyone can lend me some insight as to why this is not working properly i would really appreciate it.

Info from Cavtel:

CSU Information:
Clock Source: line
Channels: 1-24
Channel Rate/Speed 64k
Framing: ESF
Line Coding: B8ZS

Router Information:
Your T1 Serial Port should be configured as follows
Encapsulation: PPP

T1 Serial/WAN interface
Serial or WAN IP Address: xx.xx.8.142
Subnet Mask: 255.255.255.252

LAN IP Address: xx.xx.10.209
Subnet Mask: 255.255.255.248
Gateway or Remote IP: xx.xx.8.141

Your routed IP range in CIDR Notation: xx.xx.10.208/29
Usable range: xx.xx.10.210-214
Subnet Mask: 255.255.255.248

Our outgoing mail server is: smtp.cavtel.net
Our DNS Servers for your use are:
64.83.0.10 and 64.83.1.10

This is word for word what i was given by cavtel.

I feel i have set this up correctly and cavtel may have given me bad information, like this is realy a fram-relay T1, or just bad IP info. PLease double check these settings and let me know.
