WARNING: This article is under construction. The information may not be exact.
This article will describe the TelcoBridges High Availability feature. The hardware and software are design with the following 2 goals in mind:
- First and foremost, to recover from a system failure to minimize the system down time or instability as much as possible. This is achieve with a fault tolerant and redundancy architecture.
- Secondly, to keep active calls open after a fail-over whenever possible.
TelcoBridges High Availability
TelcoBridges High Availability should be seen as a collection of high availability and redundancy features instead of one single feature. This means that customer can go as little or as far as they want to create a high availability system.
Definitions
Here is a list of terms used in the description of the high availability features:
- Active Calls
- Active/Standby
- Load Sharing
- Master/Slave
- Primary/Secondary
- Resynchronization
- Switchover
- Switchover Period
- Transient Calls
