The Plot Sickens...
A technician dropped in today, tested 2 of the beast's own ADSL modems with my line - both of them synched with the DSLAM port card - he didn't do a speed test though.
My ADSL router [Billion 5102] still doesn't synch on my line, but I took my 5102 over to a friend's house this evening and it synched & connected on his ADSL line - where his Billion 5102S modem has been unable to synch for as long as mine has, BTW different exchanges - Olivedale and Randpark Ridge.
I borrowed his 5102S and not surprisingly it doesn't synch on my ADSL line either...
I tried everything I could think of whilst the technician was still around - hard reset my 5102 & changed telephone cables, nothing I try gets it to synch, and the error message in the log is always the same:
netMakeChannDial: err=-3001
whatever that means - presumably that it couldn't synch bcos the beast broke something at the Olivedale exchange...
The technician also told me that there have been major problems at the Olivedale exchange - apparently they tried a bunch of ADSL upgrades to 4Mbits/s but the exchange couldn't handle it or something [presumably ATM issues], and the solution was allegedly to downgrade a lot of ADSL lines, now I'm wondering if those downgrades included messing around with existing 384kbits/s DSLAM port cards...
