Cisco 837 ADSL Router unable to detect DSL line

I'm currently trying to set this 837 up and I'm afraid I'm not getting very far. I have tried various sample configs from people using an 837 with my ISP (Zen) as well as configuring from a standard CRWS config. Have tried configuring via SDM and using the CLI although I believe the 837 itself must be faulty so I'm just after some assistance in confirming this. The current config is:

And having run show dsl int atm0 I get the following:

Trying to bring up DSL line using Embedded firmware
Line has not yet been activated.  No information available.

Training log buffer capability is not enabled yet.

I know the line is ok as it connects fine with my Draytek. All i get on the 837 is the DSL TXD/RXD flickering together. Any help appreciated as I've been looking at this for weeks. It was originally purchased to help me learn the IOS which with trying to figure why it won't detect a DSL signal has certainly done the job!! I have tried differen IOS revisions the current show ver is below:
