- TMG3200 1+1 system (STM1, DS3, T1/E1)
- TMG7800
Components of the Tmedia 1+1 system
The Tmedia 1+1 system is made of two Tmedia units. In case of failure of the active unit, the exact configuration that was on the active Tmedia unit gets copied onto the standby unit. The standby unit is activated, and continues to route the calls.
With TMG800 or TMG3200, the Tmedia 1+1 consists of
- A Tmedia Standard unit
- A Tmedia +1 "secondary" unit
- A 1+1 patch panel to connect TDM network to both TMedia units
With TMG7800, the Tmedia 1+1 consists of
- A primary TMG7800-ctrl server
- A secondary TMG7800-ctrl server
- Multiple pairs of TMG7800 Telecommunication units (T1/E1, DS3, or STM1)
- Multiple 1+1 patch panels (one per pair of TMG7800 Telecommunication units)
Types of Tmedia units that can be purchased
- TMG800 Standard (primary) unit
- TMG800 1+1 (secondary) unit. It comes with 1+1 patch panel and cables. It's available at a discount price.
- TMG3200 Standard (primary unit)
- TMG3200 1+1 (secondary) unit. It comes with 1+1 patch panel and cables. It's available at discount price.
- TMG3200 Spare unit. Can be used to replace a failed primary or secondary unit for up to 30 days. It's available at a discount price.

Goals of the Tmedia 1+1 system
- Protect the system (no loss of service) in case of failure of a Tmedia unit
- Reduce down-time when upgrading the software or hardware of a Tmedia 1+1 system
Network connection between units of the Tmedia 1+1 system
All units of the Tmedia 1+1 system need to be connected together using two Ethernet networks. These two networks must be:
- Independent Ethernet networks
- two for redundancy
- independant to avoid interferences between them
- Private (No up-link to the LAN)
- to avoid interferences with other equipments
- to isolate multiple Tmedia 1+1 systems from each other)
Networking configuration for TMG800 1+1 system
Each unit of the TMG800 1+1 system has only two Ethernet interfaces (named voip0 and voip1). They must be shared for network communication with external world (SIP, RTP, Sigtran, H.248), and with private communication between the two TMG800 units of the system.
Two private VLans must be created to establish private and redundant network communication path between the two units:
- VLan IDs are provided to TMG800 units upon initial configuration through Web Portal
- VLans configuration in the Ethernet switches that the TMG800 units are connected to must be
- Done before starting the TMG800 units for the first time by network operator
- Must be private to ONLY the two ports the TMG800 units are connected to
