When we bought our Meridian 1 Option 11C system, we had the ability for 6 ISDN lines put into the system, yet it was never needed...until now. Now we have a very urgent need for it (as in it needs to be up and running yesterday) and it appears as though the cards (MISP & UILC) were never setup, enabled, etc. I have found in the manual how to set this all up, but I am unsure how to check if the lines are even active, how to assign them a number, etc. Any information on this and how to setup the MISP and ULIC cards from scratch (and any other settings that go along with them) would be appreciated.
