Can anyone furnish me with the tech-specs or an explanation of how the EU-PRI and the TEPRI/E differ coz I have a site where E1 point to point links are failing to work off the TEPRI cards but the EU-PRI do work;E1 that goes via client routers which are set to determine dialled routes work fine with TEPRI cards but fail when connected onto EU-PRI.
This could help to solve another issue where OS7400 PRI links from CO exchnge fail but PBX to PBX-varying vendors, the os 7400 works.
