This is really a matter between the CAD provider and the PSAP’s administration. Obviously CAD providers are looking for ways to generate revenue. However, most CAD providers are strapped for resources and do not want to write a separate custom interface for 100 different PSAPs who want to take advantage of the automated exchange. Nor are most of those PSAPs able to afford a custom interface that could cost, depending on the size of the PSAP, hundreds of thousands of dollars to create. The sponsors of the proposed standard see the ANS as the one and only approved method that all software providers should follow. In this manner, each CAD provider and each alarm monitoring software provider writes a standardized interface only once and that standard interface can be delivered to any of their customers wishing to participate in the automated alarm exchange. This method should reduce overhead costs and each software provider should be able to discount their product and spread the development costs across its customer base. Since most of the software providers are good community service partners, it is expected that they will pass along their savings to their customers.
