Existing site with a MSC-NC and several MicroSmart controllers no longer communicates. The user cannot view real-time data. The MSC-NC is proven defective. Can a UNC-520 be used in place of the MSC-NC? There are two, separate MicroSmart trunks connected to the MSC-NC.
Product failure and obsolescence
Remove the MSC-NC and replace it with the UNC-520 running a station with two MicroSmart Services - one per physical controller trunk.
