Product Description: CU2000 builds on the foundation established by the field-proven CU1000 design with far more processing power to meet the demands of Asia Cellur/Satellite System (ACeS) singaling channel. CU2000 adopts universal card design principle to minimize interface complexity, e.g. the CU2000 is powered by -48V directly, performs all NSS functions, and interfaces NCC via LAN and the TX/RX IF at 70 MHz. Besides normal channel modem functions, it offers additional features including configuration for netwokr synchronization monitoring, user-terminal-like simulation (UTLS) and user-terminal-traffic simulation.
