FLEXENT ™ MSC (CDMA Mobile Switching Center) by the FPS, ECP, FMS and the OMP composition, to provide to meet the worldwide demand for telecom operators, high reliability CDMA mobile switching center.

It uses distributed control subjects, modular system architecture, system design and load sharing modules on important characteristics of the primary standby configuration, easy-to-smooth expansion, adding new features, providing operators with the most advanced all-round mobile communication solutions.
FPS 5ESS uphold the excellent performance, providing CDMA EVRC codec and connect the base station, ECP / FMS and other networks (PSTN, PLMN, private network, heart, wireless intelligent network, etc.). FPS provides E1, OC3, STM-1, and so a variety of interfaces, support for FPS between base stations and IP transport to support circuit switching and packet switching, and integrated PCF function. Using a combination of distributed and centralized design, operator of the exchange system to meet various needs.
ECP / FMS is Flexent ™ MSC in the core, which controls the operation of the system, complete mobility management, call handling, system operation and maintenance, then a single collection and messaging functions, and have integrated HLR function. FMS using commercial SUN server platform can be flexible configuration for different functions of the server.
OMP as a network element management systems to support a single platform to manage all network elements Flexent series, that all MSC and base station products, has a good system capacity and data reliability, ease of operation. OMP's latest hardware platform SUN Netra 440 server.
