You should be able to debug the issue down. Turn on RADIUS debug and PPP 
CHAP debug on Cisco 7200. CHAP Challenge sent from Cisco 7200 to CPE 
should later be sent in RADIUS packet from Cisco 7200 to RADIUS server 
(in message header Authenticator field). CHAP Response sent from CPE to 
Cisco 7200  should later be sent in RADIUS packet from Cisco 7200 to 
RADIUS server (in CHAP-Password attribute). If RADIUS packet contains 
something different then Cisco 7200 is broken. Otherwise the CPE is broken.
