I understand about the phone charges but it DOES have some sort of "accounting" features to it Not sure how it works... you may be able to tell it to only connect manually For the most part it has been MY experience that it only connects when there's an INTERNET utility trying to find something/someone external to the computer As for analog phones, the Netgear router DOES provide two analog phone jacks. And, yes, the cost for the Netgear IS about US $200 or so, but it's pretty much "bulletproof" here. Most of our customers who use a Netgear can pretty much set it up and forget it exists. Now, just to give you an idea, I do a LOT of stuff on-line at home via my ISDN line... and I only used 14 hours in December, and about 25 or 26 hours in January... John

My phone company has supplied me with a rether large box that I connect to my ISDN line. This box is what handles my two phone numbers and supplies me with an analog line to let me use my old phone equipment.

RE: [expert] ISDN adapter questions
If you are not familiar with ISDN, be aware that any TA you use will need a "U" interface (two-wire interface to the Telco). If your TA has an ST interface you will need an NT1 adapter to convert the Telco 2-wire interface to a 4-wire ST interface. Hint: NT1 = $150.00. I only mention this because some of the PC based TA's don't have an onboard NT1. BTW !!! this info is only true for United States installations. Canada and Mexico Telco's will supply an NT1 if asked (no idea of charges). -Original Message- From: Joachim Holst [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 01, 2000 3:08 PM To: [EMAIL PROTECTED] Subject: Re: [expert] ISDN adapter questions On Mon, 31 Jan 2000, you wrote: > On Mon, 31 Jan 2000, you wrote: Hi John !

I've been looking around the net and found www.isdn4linux.de (included in both RH 6.1 and MD 7.0 I believe). According to this site, both TA's work and are supported. The HFC chip has one advantage, it can echo sent data to the isdn log and with a bit of wireing, it can do quite a lot of aother interesting things that the Asuscom can't.

This will increase my cost of getting up&running with ISDN too much. The external TA's that I've found cost twice as much as an internal. I know that the external one is an active TA that lets me do a lot of fun things like receiving faxes/voice and many also give me 2 analog lines. I believe that the same is possible on the passive cards, but require software instead. Anyhow, I don't quite need those features yet. I'm mostly in a trial period for the moment. I'm not sure that I will find ISDN useful. The word router, makes me think of a stand alone unit that is connected to the local network. In this case, in my experience I can't tell the router not to open a connection on certain packet types and port numbers. I live in Sweden with high minute rates for the use of a phone line :-( /Jocke! -- "The chain which can be yanked is not the eternal chain." -- G. Fitch

Second, I use an external ISDN router made by Netgear (who's parent company is Bay Networks...) It works like a charm! I'd really recommend that, because you KNOW it works with ANY operating system! I've got one at home and am using it with both Linux and Windows machines. We also highly recommend it at the ISP where I work. The Lucent/Ascend Pipeline series are nice, but they're rather expensive... John
