Normal POTS solid copper wire frequency is upto 1.1 MHz .. i found out. Telephone company copper wire pair ends outside my apartment into a small box and. From there on, it is connected to a paired solid copper wire which enters my home until my ADSL filter and from filter to my ADSL2+ router.

My question is.. if i replace the paired solid copper telephone wire which starts from outside my home with a CAT 5 cable, am i giving more bandwidth to my adsl modem to send data to ISP. modem? does that improve connection quality?


also..
using all 4 pairs of cat5 which I would be joined to a single wire before crimping it ) ie connecting multiple wires in parallel improve connection?

how does different types of wires in series affect bandwidth?
