Connecting Cisco IP VSAT Satellite WAN
Network Modules
This document provides hardware information about the NM-1VSAT-GILAT network module,
which provides Cisco modular access routers with two-way satellite WAN connectivity in Gilat
SkyEdge–compatible satellite communications networks. The NM-1VSAT-GILAT network module
functions as the indoor unit (IDU) of a very small aperture terminal (VSAT), or earthbound station of a
satellite communications network. A “very small” dish antenna is called the outdoor unit (ODU) of a
VSAT. As the IDU, the NM-1VSAT-GILAT network module serves as the interface between the ODU
and the VSAT LAN. The ODU receives and sends signals to a satellite, and the satellite sends and
receives signals from an earthbound central hub, which controls the entire operation of the satellite
network.
