1. Introduction
The SatLink 1000, 1910, 2000, and 2900 are the indoor units (IDUs) of the SatLink family of DVB-RCS
VSATs. They perform several functions: they are satellite modems (at Layer 1); they handle data link
layer processing (at Layer 2) for both satellite and LAN communications; and they act as IP routers and
DHCP servers (at Layer 3). All SatLink IDUs provide an Ethernet 10/100 LAN interface for one or more
PCs to engage in two-way communication via a SatLink (or any DVB-RCS compliant) satellite network.
