faceplate.
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.
NM-1VSAT-GILAT Network Module LEDs
