SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
9.1.2 In-band Signalling
In-band signaling means that the ACM signaling traffic is routed directly in the
equipment, without any external connection needed:
9.1.2.1 Why
This is used to create a link that is independent of a terrestrial network.
This provides the following advantages:
• Better security;
• Non-routable encapsulated IP packets;
• Management LAN independent;
• Simplifies the setup.
Only the devices in the setup of the satellite link have to be configured.
9.1.2.2 What
In-band Forward Signalling
In-band forward signalling is sending the messages from the ACM controller site as
non-routable encapsulated IP packets to the satellite link. The IP packets are
decapsulated and processed by the ACM client.
