EIRP Software Protection Switching The CrystalVision 2000 system implements Software Protection Switching though truth tables. Operators are made aware of equipment or signal failure where and when it occurs. Redundant equipment, chains, or entire sites can be automatically switched over to minimize or eliminate service downtime. The truth function handles all truth table activities including software protection switching while scripts are at the heart of protection switching.
Truth tables are editable text files consisting of keywords, device attributes, and values.
When all the attributes listed on a line have the specified value, the named script is executed. For example, if a device in a chain fails, using a truth table to execute a script, service can be switched to a backup device or a whole backup chain. In general, truth tables can trigger any script when a set of conditions is met. Protection Switching can offer customers the confidence of knowing that the signal will not be interrupted due to equipment failure and incur costly downtime.
