| Re: [Line Problem] Erratic DSL Performance and Intermittent Nois Testing and changes made 8/27/08:
Unless I am missing something, at least part of my troubles are caused by other than any of my internal wiring or by the DSL Modem.
Between 2:30P and 3P PDT I disconnected everything inside the house and hooked up a phone to the RJLL from the telco side of the NID to listen for static. I unplugged the RJ11 from the AT&T side of the NID and connected a phone with a DSL filter directly to the analog/DSL line. With the house analog wiring and DSL wire disconnected from the circuit I was able to hear the same kind of crackle hiss static I observed in the house, but because of other outside noises it is difficult to tell if the volume of the static was the same as in the house.
I then trimmed the wires for the analog POTS wiring to the house and reconnected them to the analog side of the splitter at the NID.
I replaced the DSL twisted pair which was in the same CAT5 cable with the two analog lines with a twisted pair in a separate CAT5 cable with the other three pairs left unconnected.
After making the changes analog static seemed greatly reduced based on occasional use, howeverat about 12:30a PDT (3:30a EST) on 8/28, I heard the same kind of static reported previously.
I ran occasional pings to the first hop DSLX router from mid-afternoon on. Several 50 ping samples showed 10ms, but other tests with 50 pings showed almost all 50 with latency around 100 ms.
In addition to continuing to run DSL Reports line monitoring and smokeping, I ran a line quality ping test. Here is the URL:
