Abstract

This paper describes the solutions needed when high availability of ISDN access established over IP network is required. SIGTRAN protocols standardized by The Internet Engineering Task Force (IETF) enable successful, reliable and timely delivery of information. These protocols are used for carrying sensitive signalling information about telecommunication and supplementary services requested by users. Although the protocols are very important, the overall availability of access is questionable without redundancy of systems involved in protocols and call handling. In this paper we describe our solution where the protocol functions and system duplications are used to offer reliable services evolved from ISDN.
