First of all you need Cisco IOS Software Release 12.2(13)ZH for adsl over isdn support.
Cisco IOS Software Release 12.2(13)ZH is a short-lived, early deployment release that will be supported in the second release of Cisco IOS Software Release 12.3T. It supports the Cisco 831, 836, and 837 routers, and Cisco 1700 Series routers Check: http://www.cisco.com/en/US/products/hw/routers/ps380/prod_bulletin09186a0080 1746b0.html sh dsl int atm 0 is needed... -- 0x8 means that the modem is waiting to hear from CO. This probably means that you do not have a good connection to the central office. Check connection and make sure the correct cable is being used. ---0x10 means that the modem head from CO and now training. The CO is connected, and the modems are attempting to negotiate a connection. If it fails in this state then there is probably some incompatibility between the ADSL interface and the central office. Make sure the correct VPI/VCI is being used. --- 0x20 means that activation is completed and link is up.
