said by imseanbrown:funny -- 586B should work... have you verified your cable works?
here's some more information I ran across which might be useful
If you are extending the DEMARK more than 15 feet, you should follow the following:
Make sure you use D-shield cable, which is CATEGORY 5 shielded. Each pair MUST be shielded, not an overall foil wrap. It you use overall foil wrap cable, you must run 2 lines, one for transmit and one from receive to the extended DEMARK. This minimizes cross talk between pairs.
That is not really required one can run a DS1 up to about 130 feet over standard non-shielded CAT3 or better cable without a problem, to run further the Line Build Out (LBO) of both the Smartjack and the CSU/DSU must be set for the proper distance.
You must use a CATEGORY 5 patch cord 15 feet or less from your equipment to the RJ-45 (RJ48C-RJ48X) connector.
Again negative any Telco or network cable CAT 3 or better will work just fine at that distance.
