Hi Paul,
ope you are doing fine! ADSL is not a valid operating mode; you can use Auto; itu-dmt; itu-ansi, adsl2; adsl2+.
You mentioning that AUTO doesn't work and it's kind of weird as AUTO goes through every other mode in succession, until it trains up. Although one explanation could be that the DSLAM is not giving any other option but the one with which the router trained up (DSLAM hardcoded to a single mode); generally these issues are related to compatibility problems between CPE and DSLAM. Let me make referencet to the following 2 documents:
ADSL2 and ADSL2 High-Speed WAN Interface Cards:

• Supports reach-extended ADSL2 standard (G.992.3) Annex L
• Supports Annex M (except UK Mask); Optimized for PSD mask M9, EU-64
• Complies with ANSI T1.413 issue 2
• Supports ATM Adaptation Layer 5 (AAL5) services
• Supports ATM CoS features constant bit rate (CBR), non-real-time variable bit rate (VBR-nrt), real-time variable bit rate (VBR-rt), and unspecified bit rate (UBR)
• Supports up to 23 virtual circuits per HWIC
• Supports IP quality of service (QoS)
• Supports Dying Gasp function
• Has one RJ-11 ADSL interface
• Interoperates with third-party DSLAMs (See Tables 1 and 2)

| auto | itu-dmt | adsl2 | adsl2+}I hope the information is useful for you.
Cheers,
