Transit Routing in the Private Leased-Line Network

When a PINX forwards a call on the network side, it is a transit routing.
If a PINX routes a call from the public network to the private leased-line network
or vice versa, it assumes a gateway function. It therefore acts as the gateway PINX
for the call.
If a PINX routes a call from a PINX in the private leased-line network to another
PINX in the private leased-line network, it assumes a transit function. It therefore
acts as the transit PINX for the call.
In this chapter you will find out how Ascotel resolves the gateway and transit
function , and the settings required.
Note:
A transit call must never be routed from network to network via the
same trunk group; otherwise this may lead to endless loops and block
all available B channels.
