Revision as of 14:12, 4 January 2010

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:

1. 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.
2. 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
