Outbound and Inbound Directions in a Satellite Communications Network
The outbound direction applies to signals transmitted from the hub to the VSAT. Within a VSAT
network, the outbound direction applies to RF communication from the dish antenna (ODU) to the
NM-1VSAT-GILAT network module (IDU). From the VSAT perspective, the outbound direction is
the receive path. Gilat SkyEdge outbound signals include user data and timing data that are compatible
with the Digital Video Broadcasting–Satellite (DVB-S) standard.
The inbound direction applies to signals transmitted from the VSAT to the hub. Within a VSAT network,
the inbound direction applies to RF communication from the NM-1VSAT-GILAT network module (IDU)
to the dish antenna (ODU). From the VSAT perspective, the inbound direction is the transmit path.
Inbound signals include user data and retransmission requests.
