Provides Bellcore's proposed generic requirements for the Integrated Services Digital Network (ISDN) Multiline Hunt Group (MLHG I). This feature provides for creation of single switch hunt groups that include hunt terminals on ISDN and non ISDN interfaces. The MLHG I feature handles both circuit mode and packet mode calls directed to an ISDN Hunt Group and provides linear hunting, circular hunting, preferential hunting (circuit mode only), uniformly distributed hunting, stop hunt (circuit mode only), make busy (circuit mode only), queuing for multiline hunt group (circuit mode only), calls waiting lamps (circuit mode only), addition and deletion of HG I members (packet mode only), and non hunt capability.
