Maybe, depending on the configuration. The NT5D60 card is like the DTRs used to collect digits from 500 sets with DTN class of service, a shared resource. If one card will handle the requests, that is all that will be required. The engineering rules are in NTP 553-3001-149.
Also note that the CLASS information is delivered in the silent interval between the first and second ring. If the called is answered quickly, the CLID information will not display. (Ran into this with an IVR that was using the feature, and set up to answer immediately.)
