6000ft ethernet extenders sound interesting. One solution we have been trying out was HPNA adapters which have range up to 2000ft on a pair of phone lines. I'd like to put internet access to the connection 1500ft away as well, so this is something I will consider.
Having some solid telco equipment could also put my mind at ease for some of these connections. Under $500 sounds great for that many extensions. Hopefully I can learn how to config it properly though :-) Funny that you mention the grounding and protection also! The system was first put up in May for about 3 weeks, then a lightning storm came and short circuited the digium FXO card in the * server. It made the PSTN lines permanently busy and no outbound calls could be made as well. It wasn't very nice! I would be interested to know how some good grounding could be put in place. Right now I have just purchased some power bars with telephone inputs, but they aren't as convenient as they only provide protection for one line... I have also attached a rough diagram of the setup for your reference (shows the location of the HPNA adapters). FYI each location of the HPNA adapters also has a phone extension. The building with the HPNA adapter and the blue cat-5 cable coming into it is the spot where the HPNA adapters need to be able to reach for the current setup to work properly (has the internet access and link to to * server). Thanks for the great info! Steven On 7/10/07, Andrew Kohlsmith <[EMAIL PROTECTED]> wrote:

I would personally recommend proper telco-grade hardware for anything like this. For FXS, a TE110P and a Carrier Access Access Bank I would be perfect, and reasonably priced on ebay. It's highly unlikely that you'll need any kind of echo cancellation on a length that short, and the ABI can drive long lines. You don't need to worry about disconnect supervision or anything on FXS ports, either, which is why you can get away with the older ABI and ABII instead of moving up to the Adit600. Adtran and Rhino make FXS channel banks as well, and Xorcom makes a USB "channel bank" as well, but I have not used any of these products. If you're running between buildings you may also need to worry about grounding and protection. I'd need to know more information to be able to tell you anything concrete, but yeah, for under $500 you can have yourself 24 ports of telco-grade FXS to play with. (channel banks and fax machines also get along great, if that is a concern.) -A. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
