| 220046 | 2004-03-03 22:41:00 | Can you get a modem which isn't working right at your ISP? Or say one which has low priority, or something similar? I ask this because sometimes when I connect (dial-up) if I can't get to any sites or even the homepage won't get accessed I disconnect and "try another modem (virtual or otherwise) at the ISP". This is how I explain it to myself. Seems to work. Or is this just coincidence and bunkum? Cheers :D |

| 220047 | 2004-03-04 00:39:00 | ISPs don't use modems on each line. They get a fat digital line from Telecom. I assume that the half-modem for 56k (modem for 33.6 and lower) processing is done in a clever box in each exchange. Again, it will be fast DSP processors in a concentrator rather than individual modems. I've seen photographs of a modem room in an American university, with racks of groups of telephone, acoustic coupler, and modem. When a phone rang, an operator would pick up the phone, answer, then put the handpiece on the coupler, and flick the switch. There you have auto-negotiation 25 years before V90. :D It's probably coincidence. But it could happen that your session at the ISP could get itself clogged up, just like Windows. Disconnecting works like Ctrl/Alt/Del. :D |
