SDSL Wiring

Posted on 2004-12-01

If SDSL comes in at a pair of wires at the NID, is it as simple as running a pair of wires from the NID to a jack for the SDSL modem?  Does the pair connect to the center two pins just like POTS or ADSL?

Note:  This is referring specifically to SDSL, not ADSL.  Thank you.

    Correct on all counts.  If you are running wire, it would be best to place a DSL splitter next to your NID, and then run CAT5 (instead of CAT3) cable to your modem.  (Or even better to place the modem next to the Splitter and run your network with CAT5 throughout the building..)  CAT 5 has more twists per inch than CAT 3, and has much better performance.

    Or run CAT5 all the way to the DSLAM.

    Actually I like to recommend CAT5 from the NID to the jack, then jack to modem CAT5 as well.  Many homes today are also daisy chained which can deteriate the signal, this is why I would recommend a direct drop between the NID and the jack.
