An NGN (next generation network) is a universal multi-service network designed for the transmission of voice, video and data on packet-based networks. An NGN provides the quality of service necessary for different types of telecommunications traffic.
Characteristically, the transmission and the routing of the packets and the elements of the transmission equipment (links, routers, switches, gateways) are physically and logically separated from the devices and the intelligence controlling the execution of the calls and services. The network intelligence supports all types of services in the packet network, from basic voice telephony to data, image, multi-media, broadband and management applications.
These features represent the basis for drawing a distinction between an NGN and an ordinary PSTN and IP network, which otherwise prevail in telecommunications. An NGN, the result of merging the IP with the telephone network, combines the best features of both.
Iskratel, in accordance with its vision and mission, offers products and solutions that give answers to many questions and challenges regarding migration stories from TDM to NGN.
SI2000 TDM (SI2000 AN, SI2000SN, SI2000 SAN) - The traditional PSTN access for analog and ISDN subscribers connected via standard copper pairs and TDM signaling (V5.2, DSS1, SS7), which was implemented over the past few decades and has become recognized all over the globe.
SI2000 Voice&Access GW - The gateway is implemented with the standard, TDM-based, SI2000 access module and an attached voice-gateway module for the transmission of voice and connection to IP networks.
SI2000 iCS is a compact version of the PSTN/NGN product that enables a seamless integration to PSTN and IP networks, with special attention paid to existing PSTN and SIP subscribers as well to the standardized transport of SS7 over an IP network
