I am adding an Option 11C to a new building about a mile from our data center. At the data center we have an Option 61C with an Octel 250. I am going to TIE the two sites together with and ISDN T1 and need to get the message lights across to the new site. Is this possible, and if so what is the configuration? I checked the pacakges in the PBX and I do have 175 for network messaging.
