Cisco Cisco Catalyst 6000 Multilayer Switch Feature Card MSFC2 Installation Guide

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.
