SM2000

Time and Frequency Synchronization Device/Network Synchronization Device/Bits Device

SM2000

Product Overview

The SM2000 is a carrier-grade, high-precision network synchronization device/time and frequency fusion platform that supports IEEE 1588. It utilizes digital phase-locked loop (DLLL) technology and an independent timing algorithm based on an FPGA (field programmable gate array) to provide high-precision and reliable time and frequency reference signals. The device provides a reference clock source compliant with ITU-T G.811 and G.812 standards; a traditional 2Mbit/2MHz frequency synchronization signal; and time outputs such as PPS+TOD, NTP, and PTP.

Features:

Supports IEEE 1588v2 and provides Layer 2/Layer 3 PTP output

Supports hot-swappable cards and expansion chassis

Passes Level 1, 2, and 3 network access tests by the Ministry of Industry and Information Technology

Passes Level 7, 8, and 9 earthquake resistance tests by China Telecommunication Technology Laboratory

Passes low-pressure testing, suitable for use in plateau areas

Supports CLI, SNMP, and TLI configuration and management

Main Applications:

Mobile operators' communication synchronization networks, power system communication synchronization networks, rail transit, and other synchronization scenarios.
