I have a 1841 with a 2SHDSL wic, testing using a BT SDSL circuit which works fine on a Cisco 878 router.
When I plug the same circuit into the SHDSL interface using the standard straight through cable which come with the 878 I am having issues with the DSL state transisioning from DSL UP to DSL DOWN and the light on L0 intermiently flashing. The atm pvc is established, but the virtual access interface has line up but line protocol down. The config of the controller is below I have a feeling the issue is with the cabling.
Has anyone come across this before or any suggestions would be welcome.
controller SHDSL 0/0/0
dsl-group 0 pair 0
shdsl annex B
shdsl rate auto
