I hope you get an answer from the group...
Over the years, sometimes when I run into these types of "issues", I end up calling BlackBox's (www.blackbox.com) technical line and ask them. Usually with great success. Not trying to plug for their products (although they do have some amazing stuff), just a plug for their free technical support/consulting on the phone. Usually, I ask them about which products would allow me to do XYZ. Explain the problem... sometimes they say you don't need a product, what you have will work, etc... Good luck!

Hello All, Does anyone know the length you can run a FXS extension on copper cable pair (24 AWG)? I'm replacing a Nortel legacy PBX with an Asterisk server. Most of the lines are IP, but some of the extensions are outdoors in different buildings, up to 1500ft. If possible I would like to use an external analogue adapter for these extensions. I've check the techinal specs on the Grandstream GXW-4008 8-port FXS, and it lists a specification (REN 3 - Up to 150ft Short and Long Haul). I've tried to dig around on the net for information on max cable runs and "Short and Long Haul", but haven't been able to find much. Could something like a SPA-2100 work, or a TDM400 card with FXS ports? Thanks in advance for any feedback. Regards, Steven
