| 119850 | 2003-02-10 06:30:00 | Well Biff, Ive bought a filter now, plus one that came with the Dynalink ADSL router. Not too sure, but I'd have thought a splitter would have had a low pass filter in it for the phone same as a line filter. Maybe still have the same problem. However the mystery deepens even more!!!!!!!!! Pulled the Pert phone apart and pin 4 of the BT plug is not connected, ie the Pert phone is a 2 wire device, so why there is no ringer with the filter attached is still a mystery. It does have an earth connection on pin 3 though, odd. Thought I'd cracked it. Maybe have to get new phones. |

| 119851 | 2003-02-10 18:41:00 | Yippee, the ringer problem with Pert phones is solved :) PTC 200 section 10.2 says pin 6 of a BT plug is next to the latch, now either this is in error, or there is a wire reversal, or I have a vision reversal, because what I thought were pins 2 and 3 must be pins 5 and 4. Connecting a 1uF between 5 and 4 (as recommended in the ADSL filter PTC 280 )works, now I have ringer with the phones plugged into filters. Thanks for the help Graham. |

| 119852 | 2003-02-11 02:25:00 | Perhaps my pin numbers were right initially. B-) That would mean that the PTC is wrong. :D In either case it was just a 1:6 reversal. BTW ... I recently installed Chris Pugmire's fine GLE graphics package on a DX2-66 I've been playing with. DSIR did some good things until they got corporatised and efficiented to death. |

| 119853 | 2003-02-11 03:50:00 | GLE is a really great program. I dont use it now, but one of the best graphics progs in its day, probably still is. I think the different packages are still on Simtel. |

| 119854 | 2003-02-11 04:25:00 | Yes, it's in the msdos/graphics directory on Simtel. I got it first by FTP from the DSIR vax cluster. But the fonts discrepancy is still there. I might see if I can sort it out, one day. | Graham L (2) | ||
