Support for OPX analog lines?

Unanswered Question
Jul 17th, 2007

I have a site that has this set up on an old phone system and need to support it in the new CME. I am having a tough time figuring out if I can get support an OPX line for a remote analog phone on a 3800 router. I see the plar opx stuff for FXO ports but this isn't what I'm looking to do. I would think that I need it on the FXS side. Anyone know if this is doable?

I have this problem too.

Hi,

Almost anything is doable with cisco. Please tell how do you want things to work and we can suggest a config. please state which type of pstn lines you have on the ISR router.

The router has a 2 port FXS and a 4 port FXO. The line in question is a OPX analog line that runs about 2 miles away. Being that it's an OPX trunk, I'm not sure that it would work properly off of an FXS port..especially at that distance.

I would try anyway. if the line is 'conditioned' will work no issue. And chances are, will work even if dry pair.

Did the FXS port work for you ?

I am in the same boat and wondering if you tried this soluton
