Are you sure there is a splitter in there, I see two feeds appear to be leaving the demarc but is it just two direct feeds do you know a filter was wired in.

hey man theres a Black spiltter inside the white box , i would open it but i dont have the special screwdriver, i dont know how its wired up but the white cable coming out is for this DSL jackpoint and the 2 black ones at the back goto the main phone jackpoint. i wanted to know if i should get the black taped thing checked becuase there is a lot of water in there and would cat5e work from the white box

thanks

Hi, OK just needed to confirm that a filter had been fitted. Changing to Cat5 would not improve things, cat3 (that white wire) is fine for ADSL, what is more important is that it is a direct line without stubs or branchs from the demarc to the modem.

As for the water in the joint, assuming the joint was made with gel impregnated crimps it should be fine.

What is more important are the figures your modem report, in particular the down stream noise margin (or S/N) and the attenuation.

heres my stats

ADSL Link	Downstream	Upstream
Connection Speed	3424 kbps	160 kbps
Line Attenuation	45 db	15 db
Noise Margin	10 db	27 db

my downstreama attenuation n noise range from 44-45 and 10-15db depends, i was gettng alot of disconnections for somereason even with splitter installed so they changed my profile to a slower one they dont tell me why i was getting d/cd but profile is slower now i used to gt 4000-5000 now max is 3700

edit - on the mt roskill exchange aswell

Hmmm, those figures arnt too flash, a good line at 45dB and 10-12dB S/N should run 4.5-5Mb/s, however disconnections can just as easily because by poor modems as well as bad joints. Thing to remember is that the joint you see before you is possibly only one of many on the line, you just dont know how many cables have been linked to get the 3.5km you are from the switch.

Regardless those joints as you see are designed to withstand weather, the black boot is just a extra protection. One would have assumed that when the tech installed the filter the condition of that joint would have been taken into account.

i used to get 4.5-4.9mbit but used to get alot of d/cs sometimes id be connectd to exchange but no ip or link speed everything was blank then had to powercycle this used to happen alot then, xtra changed my profile on the exchange to a 3mbit profile

when the tech came over he didnt look at tht joint he just ran the wire to the new jackpoint and then just connected up the splitter :/

hopefully they will reset my profile to the faster one when my exchange gets migrated to dsl2+
