4 Using RAD Vmux trunking over BGAN

• Vmux does not require any additional external equipment or special configuration to be used over

BGAN networks.

• Bandwidth required for the specific voice channels connection can be easily calculated by the Vmux

Bandwidth Calculator.

• Maximum Packet size is 1515 bytes (maximum payload is up to 1461 bytes and ETH frame fields

require 54 bytes, so in total 1461+54=1515).

Analogue Compressed Voice Solution Configuration

The above diagram illustrates a compressed voice connection over a BGAN link.

• The Vmux on the user side has IP address 192.168.128.101 and Default Gateway 192.168.128.100

configured (as required by HNS 9201 NAT structure).

• The Vmux on the PBX side has a static IP address and Default Gateway provided by the Network

Administrator.

• The bundle (logical channel responsible for compressed voice end-to-end transferring) should be

configured with the following destination IP addresses:

o HNS 9201 network address for PBX side

o Vmux network address for the user side
