RE: ISDN Jack Installation
Hi Evan, Let me just clear up some misconceptions here on ISDN. Dual channel dialup BRI ISDN is 128kbt/sec both directions, not 64k. ISDN channels on either a BRI or PRI ISDN can be either voice, or data, or both. It is a circuit-based, not a packet-based service, which makes it extremely useful for certain applications. Videoconferencing being one of them. It can also run an indefinite distance from the telephone central office, because the CO can install repeaters on an ISDN line. Because the line is a digital line, telephone calls over it have superior voice quality than ones over an analog line. ISDN isn't as popular for data use these days because it is not as fast as cable or DSL. But, cable isn't in all areas and neither is DSL. ISDN by contrast reaches something like 99% of the subscribers in the United States. If your new house is out in the boondocks, ISDN may be the only faster-than-dialup connection you can get. ISDN PRI's delivered in the United States are delivered on T1 interfaces and are typically not used in a home so I will say nothing further about them. ISDN BRI circuits as delivered in the United States are delivered on a single pair comprising a U interface. The only difference between an ISDN jack and a regular Plain Old Telephone Service (POTS) jack in the U.S. is that ISDN jacks are RJ45 jacks, POTS jacks are RJ11. But the only reason that the telephone company uses RJ45 jacks is so that a telephone company technician on site can immediately identify that the jack is a special service jack. It is a telephone company standard to use RJ45 for anything that is not a POTS connection. There is absolutely no electrical requirement that ISDN uses a RJ45 jack, and RJ11 jack will work fine. There is also no electrical difference in the cable requirements for ISDN vs POTS. ISDN in the United States uses exactly the same number of conductors in the cable as POTS so there is no need to run extra pairs. My advice to you since your having a house built is for your installer to run plastic interduct to all the rooms for data cable. Interduct is like a small flexible vacuum hose. It is very cheap. The usual procedure in a home is to run regular old strings inside the interduct, run the interduct, making sure to use large radius bends in the interduct, then drywall. In this way if some idiot makes a mistake and drives a nail or screw into the interduct it will not penetrate a cable. Once the drywall is up, an installer can come along later and tie cables and more string to the existing string, then pull the existing string to draw the new cable and string through the interduct. Or if you do not want to rig that particular room, you can just leave the string only in there for future use. And even if the string breaks an installer can snake a fishtape through the interduct to pull cable. Run all the interduct in a hub-and-spoke fashion, with it all terminating at a single location, such as the garage or utility closet. Make sure that there is at least an electrical power outlet at that location, and make sure that there is an interduct from that location to the telephone company MPOE on the outside of the house. Nobody knows what future cable will be designed and used. It is rather foolish in my opinion to merely run cat-3 phone-grade cable or even cat-5 data-grade cable in a new house, when you can run interduct much cheaper then pull as many cables and as different types of cables as you need later on. You may want to run tv cable, you may want to run alarm cable, in addition to ethernet and voice cable.

Will DSL be available where your house is? That might be better. It is faster. Of course you might want ISDN for phone line purposes. jerry ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You can't run it on the same wire your phone service and use filters to allow their simultaneous use. But installing it yourself is very easy. All you need is a Cat3 (standard telco) cable run from the NID (network interface device - where the phone lines come in the house) to where ever you want the ISDN service. The telco hooks the wires (single pair) together at the NID, tells you which colors to use at the receptacle, and you just saved yourself US$100-$300. HTH, Stheg __ Do you Yahoo!?

Re: ISDN Jack Installation
You don't want ISDN. A single ISDN line is only 64K and if you don't use a separate line for the ISDN, you interrupt your normal phone service. To get faster ISDN, you have to put in two lines at X$ per month. If you later switch to DSL and want to use your ISDN line(s) for that, you're still paying for an extra line (in my case I was paying for two ISDN lines). If you use DSL, you can use your regular phone line, have a full time connection and not disrupt your regular telephone, requires filters to be plugged in on all the regular phone jacks in use. Skip the ISDN and go straight for DSL. The other option is cable. Do not use satelite, you still have to use the phone line (read that as install another line or interrupt what you have) for uploading. Don't do it. Donald J.

If you use DSL, you can use your As a guy who has not one, not two, but THREE (3) defunct (or never worked) DSL lines to his apartment, I gotta say go cable modem Cable TV companies have a broad customer base, with a stable steady income to weather them through weather them through what? You mean, weather them through the times that all their Internet subscribers get sick of their crap and pull their Internet service? Cable companies have little interest in Internet because they make the bulk of their money off selling tv content, payperview, and porno channels. The Internet connectivity is just a way they can get a cable line into your house and get your name so they can pitch their higher margin tv programming to you. Cable companies are monopolists who have the tv content regulated by local governments, as it should be. But the Internet content, although it's a monopoly too, they have managed to wiggle out of getting regulated. As a regulated monopoly a cable company can never lose money. But, just because they cannot lose money doesen't mean they are rolling their profits back into infrastructure investment in their networks. There is no guarentee that any part of this stable steady income is ever going to fund any Internet infrastructure investment in a cable company. There might be if Internet under cable was regulated, but it's not. -- The odds on cable TV suddenly not being available at your location in anything but truly rural or even remote areas is nil. Same is true of DSL. DSL? Fah. You're lucky if the company you call today for a price quote is still around in 12 months. Of course, there are some drawbacks to Cable such as you don't generally get a static IP number. DSL providers by contrast usually have them available, save the garbage grade ilec isp's. Also, look at the acceptable use for cable, servers of any kind are prohibited. Just because you were burned several years ago doesen't mean the DSL market is still the same. Northpoint and Rhythms both went bankrupt, but Covad is still running, and ILEC dsl is perking along fine. Sure there are some smaller ISP's who were provisioning over ilec DSL who gave it up after they couldn't make money on it. But they are all out of the market now, and the people left in the DSL market are there for the long haul. And sure, there's some areas that DSL cannot reach, and that cable can. I also know of areas that cable cannot reach that DSL can. In most major markets you can count on at least two regional ISP's who are provisioning over ILEC dsl, you can count on MSN and maybe one other national ISP also provisioning over ILEC dsl, and the ilecs of course themselves have their own ISPs that provision over ilec dsl, and to top it off you can also count on att/earthlink/mindspring provisioning over covad DSL. And today, covad is radsl over voice, they don't require a separate phone line anymore. By contrast with the cable companies you can count on 1 monopoly ISP and if you don't like the way they run their network, you can go to hell.
