MDM9000 Satellite Modem
In-band Forward Signaling
In-band signaling messages coming from a controller are IP encapsulated and forwarded over the
satellite link.
The messages arriving on the receiving site are IP decapsulated and routed to the client. The client
interprets the messages and provides an answer.
In-band Return Signaling
The client answers to the messages from the controller. The answer is IP encapsulated and returned
over the satellite link.
The answer is decapsulated and routed to the controller. When needed the device settings are
changed.
For example: FlexACM Signaling

1. The ACM controller broadcasts the ACM system settings.
2. The request is IP encapsulated.
3. This message is forwarded over the satellite link.
4. The request is decapsulated and routed to the ACM Client.
5. The ACM Client interprets this message and provides an answer
(For example: new MODCOD request!!).
