What is the standard setup for a Meridian Option 11C rls 24 to a Norstar rls 7.0 system. We have a PRI point to point T-1 and the Norstar has the PRI key code and the Option 11 has the NTAK09 card wiht the PRI daughter board. I have tried setting it up as ess4 and dms 100 but I am not able to access the trunks (no lines free) Any help will be appreciated.
