And has | the wrong name. ADSL is a layer 1 technology. ISDN also defines layer 1. | Something like "ADSL over ISDN" doesn't seem to make sense. I have limited knowledge on this basically given to me by Telstra rep, who has been know to lie to me before, but, here goes... ADSL depends on DC continuity, it some places like Australia you can't get this, and so any ADSL connections are limited to your exchange (if you're lucky enough to get that). Infrastructure changes are in place here to be able to offer ADSL services (but, I really don't think this means laying copper in the street). | And it doesn't provide any serious advantage over plain ISDN. Other than giving you the ability to do ADSL to places you wouldn't normally be able to. And 2xB +D IDSL is faster than 128K ISDN (1.5M I think), so you still get a definite speed increase. -- Totally Holistic Enterprises Internet| P:+61 7 3870 0066 | Andrew Milton The Internet (Aust) Pty Ltd | F:+61 7 3870 4477 | ACN: 082 081 472 ABN: 83 082 081 472 | M:+61 416 022 411 | Carpe Daemon PO Box 837 Indooroopilly QLD 4068 |akm@theinternet.com.au| To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
