I am trying to configure a shdsl port on a 2911 router for CO mode of operation.
The dsl-group auto command does not seem to change the port to operate in CO mode and the link will not come up to a remote router that has a card installed operating in CPE mode.
The configuration I have applied for the shdsl controller is.
controller SHDSL 0/1/0
dsl-group auto
!
!
Do I need to use a HWIC-4SHDSL card for the CO mode operation?
Solved! Go to Solution.

Hi,
to force CO mode you need to configure 'termination CO' under the controller SHDSL.
However, only HWIC-4SHDSL supports that command. See here for reference:
"Q. Do the G.SHDSL HWICs work in central-office mode (back-to-back connection without a DSLAM)?
A. Currently only the HWIC-4SHDSL supports both CPE and central-office modes for diagnostic purposes. The mode of operation can be set only from the ROM Monitor environment. CPE is the default mode of operation."

Hope this helps

Thanks Marco. I thought they might have fixed the issue with the 2SHDSL card when used in a 2900 router as the WIC-1SHDSL-V3 card is not supported on this platform and from the device configurator the HWIC-4SHDSL card is not an option and trhe EHWIC-4SHDSL-EA card is NPH until March 2012. This leaves very little option for routers to be ordered and installed in the next month or 2.
