My house has a single wire coming from the Telecom demarc point to a single telephone point in my 'server closet'. Plugged into that is a in-line filter (i.e. the kind supplied with most ADSL modems that has a plug for DSL and a telephone jack). Plugged into the telephone jack is a cable that runs to a patch panel and threads itself through four of the jacks (jacks 20 - 24). The ADSL modem is then plugged into the ADSL plug on the filter. The rest of my house is wired with cat 6 cabling I run recently which all terminates in the closet, running to a patch panel and then to a switch (where necessary), and there is only one phone patched into one of the phone jacks (obviously not running into the switch).
I have two questions:
1) Is this a suitable setup, or should I install a proper master filter?
2) The only cabling I have not changed is the cable running from the demarc to the phone socket in the closet. It looks relatively old but I have no particular reason to replace it. Would you recommend replacing it, and if so what with - should I run just a cat 6 cable, or should I future proof with a cable for fibre as well?
Separately, I've noted the following details from my modem (which is providing ADSL2+):
SNR Margin: 106 down / 124 up
Attenuation: 95 down / 26 up
Attainable Rate: 23056 down / 1048 up
Rate: 19990 down / 1000 up
I live slightly outside Palmerston North in what would be classed as a rural area. According to the Chorus Service Availability Tool I am in what is an exchange area with Rural Broadband Initiative available. Do these figures look appropriate? Attenuation / SNR seem high to me, but I'm not well enough informed to be certain.
Your feedback would be hugely appreciated!
