Abstract
Abstract The termination availability database (TADB) of the instant invention performs routing decisions in response to call requests received from data access points (DAPs). The TADB takes each of the requests, which relate to a special service call of a subscriber, and determines the particular termination of the subscriber to which the call is to be routed. To perform its determination of where to route the calls, the TADB takes into consideration data collected from the network and the availability of the different terminations of the subscriber. In addition, allocation algorithms are used.
