VB243 ASI INTELLIGENT REDUNDANCY SWITCH

The VB243 provides full dual path redundancy for ASI signals with autonomous operation and deep signal analysis on both signal paths for the ultimate switching decision making. Front panel controls with illuminated buttons offer local override control and a clear visual indication of the active switching path.

The redundancy switch offers three distinct modes of operation making it suitable for any real-life operational challenges. These are Automatic mode, Manual mode and SuperLocal mode.




Figure - Pictured is a complete VB243 system with a VB120 controller, a VB242 ASI input blade and a VB243 ASI 2:1 switch blade housed in a 1RU Redundant AC powered chassis. Not shows are the two factory fitted connecting cables between port 1 and 2 on VB242 and the VB243 switching module. The power consumption of this configuration is a modest 25W giving additional savings in operational costs.

The VB243 INTELLIGENT REDUNDANCY SWITCH has multiple layers of redundancy. The 1RU chassis offers dual redundant power supplies and the VB243 switching card has magnetically latching relays to protect against signal disruption even during a complete loss of power.

The VB243 switch module actively taps off a small portion of the input signal from both inputs, amplifies it and then feeds it to the neighbouring VB242 ASI input module via two factory fitted cables.

This allows monitoring and analysis to take place on both inputs simultaneously for switching purposes.

If any problem in any parameter is detected preset rules apply and the unit will check the opposite input for the same failure and perform a switch if no failure is detected. To avoid switch flapping a minimum switchback time can optionally be configured. All the parameters in the implementation of the TS 101 290 specification can be utilised as switching criteria

In automatic mode the VB243 system is fully independent and makes its own switching decisions based on the preset switching rules. In manual mode the unit can be controlled from any overlying NMS system via the extensive XML-based Eii (External Integration Interface) or via SNMP triggers.

The VB243 also features a unique superLocal mode feature to deliberately cut off overlying NMS control for emergency manual override situations via the front button panel. All parameters can be controlled via the built-in web GUI. The web GUI also gives a visual overview of parameters used in switch decisions and system status.

The VB120 blade offers a bonus ASI input port with TS 101 290 analysis support that can be used for ad-hoc monitoring in addition to the two main ASI input ports used on the VB242 blade should the need arise.
