CAT 3 with POTS drop? |
|
|
Is there any real advantage of using cat 3 for inside wiring for a DSL
installation when the drop to the residence is only a POTS line? The
baud rate would be limited by the drop, I would imagine, but would the
added CAT 3 (or better) make real difference with signal quality?
Underground drops aren't readily replaced by phone companies around
here.
Thanks for replies!

TIA 570B recommends a minimum of Cat3 for any residential installation. |
When I relocated mine, I used Cat5e just for the peace of mind knowing that
the little performance gain was enough. Plus I had the cable on hand.
I'm sure that there are thousands upon thousands of people using IW for
their DSL without problems. It's a judgment call. |

Skip CAT3. Use at least CAT5E for ALL your wiring, voice and data. This
way you'll take advantage of the higher throughput if you re-allocate a
voice drop and make it a data drop in the future. True, it will not
improve your DSL, but in reality you should not even distribute your DSL
throughout the house: you should terminate it on a DSL modem which will be
sitting next to your patch panel.

Cat 3 cable is better than most of that, which the DSL signal passes over.
It won't do much either way. However, if you're running new cable, go with
Cat 5 or better, so that it'd be suitable for network use. |

I agree. I hate seeing those filters, scattered around someone's home.
Split the signals near the entrance and send them over their own pairs or
cables. A good choice for DSL, would be the 3rd pair in a 3 pair cable, as
most phones won't use that pair. |

The reason the FCC recently required a minimum of Cat 3 is because of |
numerous reports of crosstalk between multiple phones when traditional
quad-four wire is used. BTW EIA/TIA considers Cat 3 obsolete the minimum is
Cat 5e or Cat 6. Technically Cat 3 is fine for POTS.
I'd use TIA rated structured wiring for all new installations. As others
have posted if you are going to install new wiring use a whole house
POTS/DSL splitter to separate POTS from DSL near the Telco NID.
