Have a Opt 11 rls 25. with a pri to a Norstar. Set up dchl with a IFC of sl1 and everything was all right. Customer wants to put fiber in and is using Adtran equipment. They want me to change the ifc to NI2. The Opt 11 has to be a did to use NI2. When we change both sides to an NI2, I can use 4 digit dialing between switches, but the Norstar can't dial out, it ends up at the Opt operator, and incoming calls to the Opt 11 to the Norstar goes to the operator in the Opt 11. I am not using the fiber as of yet, so I can work out bugs. Must be an option because of pri being a did instead of tie, but can't find it. Any help out there.
