SatLink 2000

VSAT Indoor Unit

The SatLink 2000 is the preferred, most cost­effective option for sites in many types of
VSAT networks, including public ISPs and
private encrypted networks. Yet, it has download IP throughput up to 30 Mbps, advanced
QoS, and TCP & HTTP Acceleration up to 10 Mbps per connection. Like its larger cousin the
SatLink 2900, it also delivers the best spectral efficiency by using the DVB-RCS2 standard
supporting QPSK, 8PSK, and 16QAM on TDMA carriers. The SatLink 2000 also has all the value­added IP networking features customers expect in SatLink networks. The SatLink 2000
supports various antenna options, with BUCs/LNBs in C, Ku, Ka, X, and EHF bands, including
STM’s own Ku Band transceivers.

The SatLink 2000 VSAT is a member of a family of SatLink products and systems from STM
enabling scalable, high-availability DVB-RCS & DVB-RCS2 networks including: VSATs, Hubs,
and Hub components, with value-added options for advanced data, voice, and video
networking via satellite. STM is the technology and market leader in DVB-RCS & DVB-RCS2
satellite networks delivering superior performance for telecom service providers, ISPs,
governments, and enterprises around the world. STM also offers integration, installation, 24x7
global support, and managed network services.

Features & Benefits

● Cost-Effective, High-Performance VSAT

The SatLink 2000 offers exceptional price-performance
advantages with 30 Mbps of download IP throughput,
excellent availability on all links, TDMA return links up to
5 Msps, and Bandwidth-on-Demand with QoS.

● Plug & Play Integrated Design

The integrated hardware design and DiSEqC interface
greatly reduces installation errors while also reducing
installation time and complexity. The IDU monitors and
controls actual ODU power output allowing self-install.

● Scalable Management & Control

All management & control processes are engineered
for large networks with up to 10,000 VSATs per DVB-S2
carrier, with automatic software updates via multicast,
efficient statistics collection, and fast, easy network­wide reconfigurations, without site visits.

● Comprehensive IP Networking Features

SatLink delivers TCP and HTTP acceleration, secure
VPNs, NAT, and VLAN options, as well as a built-in
DHCP server and both unicast and multicast IP routing.

● Bandwidth Efficiency at Many Levels

8PSK and 16QAM on return links with 16-state Turbo
FECs, header compression, section packing, burst size
optimization, & intelligent bandwidth-on-demand
algorithms assure efficient broadband applications.

● ACM on Forward & Return Links

Adaptive Coding and Modulation (ACM) is performed
on DVB-S2 forward links and RCS2 return links (per burst),
enabling maximum two-way link availability. ACM is

integrated with SatLink’s QoS & Traffic Engineering so

key customer service levels can be met during fades.

● VSAT Groups, Traffic Engineering and QoS

SatLink allows operators (and VNOs) to set up different
virtual capacity pools (with max and min rates) for
each QoS class used by each of a number of VSAT
Groups. This give operators more flexibility & control on

the service tiers they can offer. SatLink’s advanced

QoS features enable all data and media types to use
bandwidth-on-demand while key quality metrics, such
as jitter, delay, and throughput, are held within bounds
set for each VSAT Group and each individual VSAT.

● Compact, Fanless Packaging

Its small size, fanless design, and external power supply
make the IDU ideal for desktop environments in
businesses and for residential uses.

● AES-256 Encryption Built-in

Built-in AES-256 secures all user IP traffic at Layer 2 with
traffic key per VSAT Group and automatic key updates,
fully transparent to TCP acceleration.
