Network Redundancy
It is possible to connect a network redundancy via a second cable from the second ethernet port of the
G8-NET. If one cable to the switch is defect, the second connection automatically takes over.
Note: For network redundancy the switch must support Rapid Spanning Tree RSTP functionality!
Required Bandwidth in the Network
The connection of GE 800 Intercom Servers creates a load on the IP network with the speech and con-
nection data. These must be regarded when planning the system together with the network admini-
strator.
One 16 kHz conversation requires 146 kBit/s
The advisable load of a 100 Mbit/s network = 40 Mbit/s
Therefore 40 Mbit/s can be transmitted in the network
This bandwidth minus the bandwidth already used in the network is available for the Intercom
system
Always plan a reserve!
Example
40 Mbit/s = 270 conversations between two segments when no other load is on the network
