OPNET Technologies has focused on telecom access network development, and has cultivated a deep technical capability. With the trend of IMS/IP network, its R&D products are gradually becoming IP-based and comply with the operators’ requirements.
In response to the migration of the telecom core network from the traditional TDM-based PSTN to IP-based IMS technology, it is necessary to retain the existing telephone use habits and methods of fixed networks and their functions, without requiring users to change their terminal equipment, such as telephone sets, fax machines, or PBX. A telecommunications-grade voice gateway system is the best tool for fixed network operators to keep their fixed-line subscribers.
- Smooth migration from traditional PSTN to IMS core network.
- Supports traditional PSTN services, such as FXS, FAX, ISDN PRA, Centrex and Voice band data (VBD) in IMS core network.
- Carrier-grade, high-density, high-reliability gateway system.
