Brief Introduction
Unlike the traditional A/B switch, the FT50-T3-PBX enable both the master and slave transmission links simultaneously, monitor the quality of data received from both paths, and intelligently make-up the decision to accept the data received which is totally error free. Even the device is powered off, the data will be by-passed automatically. For such both active transmission links technique, it guaranties the maximum availability of data transmission and non-destructive switch over.
When switch over is triggered by error rate or just only the receive path is disconnected, single end switch is appeared, the other end will maintain as usual, that can maximize the system availability. All types of card and power module are hot swappable, and the system will memorize the best receiving data path and resumed as before after the maintenance.
The FT50-T3-PBX is widely used for the most valuable data protection and provides the best data services for banking, aviation department and public electric facility.
Features
- Extremely high hardware and circuitry reliability, chassis supports 1+1 power supply, and all types of circuit board are hot swappable;
- High integration for only 1.5U height chassis, supports up to 8 E1 channels protective switching;
- Automatic by-pass when power is off for guaranty data services continuity and availability;
- Both master and slave links are active all the time;
- Non-destructive and seamlessly switching for highly system availability;
- Receive paths are monitored and the best quality data will be sent to the user device;
- Any type of alarm, such as LOS, AIS or E3, E6 error rate appears on the receive path, switch over is triggered;
- Single end switch due to the receive data quality is turn bad in one side;
- Best receiving path is memorized and resumed automatically after maintenance.
