Advanced services for rural telephony

Subscriber demands in rural areas for enhanced features and services equivalent to those available in metro areas are increasing. These demands are driving intelligence and functionality currently associated with metropolitan digital switches down to the access network, a trend that will lead to an increasingly distributed switch architecture. This paper examines these requirements, and describes a method of interconnecting the DMS 10 rural digital switch to the DMS Super Node exchange in order to provide cost-effective access to the sophisticated features of the DMS Super Node host, as well as stand-alone implementation of specific sophisticated features directly in the DMS-10 using a Reduced Instruction Set Computing (RISC) processor.
