i want to know can i configure two cisco 2811 with G.SHDSL HWIC (with Cisco ISO 12.4T-15)installed in back-to-back operation that one of my Cisco 2811 setup as CO (central Office) and the other one in CPE mode when i only have copper lines (without DSLAM).the cisco website mentioned about this feature only on Cisco 878 and old G.SHDSL-v3-WIC .

Hi,
It works fine. Configure one side as co and the other as cpe.
controller SHDSL 0/1/0
termination co
dsl-group 0 pairs 0
shdsl annex B
shdsl rate 2304
interface ATM0/1/0
no ip address
load-interval 30
no atm ilmi-keepalive
!
interface ATM0/1/0.10 point-to-point
ip address 10.10.0.1 255.255.255.0
pvc 0/10
protocol ip 10.10.0.2 broadcast
The CPE side is the same except the controller configuration (and the IP-s of course). If you match the right pairs it will work.
Here are the pin assignments:

thanks to your reply.
but there are some issues :
1-the url that you mentioned , obviously describe that only HWIC-4SHDSL supports both CPE and central-office modes for diagnostic purposes and only in ROM monitor mode.
2-some people argue (in this forum) that the commands for CO/CPE is not avaiable to configure (i think because this HWIC only support CPE mode).
while i am going to buy the hardware from my budget for my customer and i think it is possible that this new HWIC don't not work in Back-to-Back operation i prefer to buy Cisco-878 that cisco website clearly defined it work in back-to-back mode (with no DSLAM).
something else : are you sure that you run new HWIC-4SHDSL on Cisco-ISR ? or you run the old G.SHDSL-v3 WIC ?
again thank.
