This article describes the TelcoBridges Tdev High Availability feature. The hardware and software are both designed with the following 2 goals in mind:
- First and foremost, to recover from a system failure and minimize the system downtime or instability. This is achieved with a fault tolerant and redundancy architecture.
- Secondly, to keep active calls open after a fail-over, whenever possible.
Important:Tmedia high availability features are described here
To learn more about high availability and redundancy, see TelcoBridges website.

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 customers can do as little or as much as they require to create a high availability system.
Definitions
The following list of terms are commonly used in the description of high availability features:
- Active Calls
- Active/Standby
- Load Sharing
- Master/Slave
- Primary/Secondary
- Resynchronization
- Switchover
- Switchover Period
- Transient Calls
High Availability Features
Hardware High Availability Features
- Dual Power supply
- Networking
- Host redundancy
- Tdm Interfaces (OC3/STM-1 APS)
- Clocking (Multiple clock sources)
