The SatLink 2900 is ideal for carrier
and ISP networks offering high-
value broadband multi-media services, given its 50 Mbps of download IP throughput, QoS
for all media types, and TCP & HTTP Acceleration up to 10 Mbps per connection. Special
features such as: AES encryption, options for mobile configurations, an SCPC mode, and
built-in mesh networking support add to its versatility. Like its smaller cousin the SatLink 2000, it
also delivers the best spectral efficiency by using the international DVB-RCS2 standard
supporting QPSK, 8PSK, and 16QAM on TDMA carriers. The SatLink 2900 also has all the value-
added IP networking features customers expect in SatLink networks. The SatLink 2900
supports various antenna options, with BUCs/LNBs in C, Ku, Ka, X, and EHF bands, including
STM’s own Ku Band transceivers.
The SatLink 2900 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.
SatLink 2900
VSAT Indoor Unit
The SatLink 2900 delivers 40 Mbps of download IP
throughput for broadband services using either
Bandwidth-on-Demand or SCPC mode and the
highest spectral efficiency. Its mesh networking option
has low-blocking probability with its ability to receive 8
concurrent bursts.
● High-Capacity with Mesh & SCPC Options
Features & Benefits
Can use either AC or 24 VDC power feed. Internal
power to drive BUCs up to ~8 Watts. Automatic power
control from the hub simplifies installation and optimizes
operation and bandwidth use.
● Power Options and BUC Power
Secures all user IP traffic transparently, with support for
traffic key per VSAT Group and automatic key updates.
● AES-256 Encryption Built-in
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.
● Comprehensive IP Networking Features
All management & control processes are engineered
for large networks, with automatic software updates
via multicast, efficient statistics collection, and fast,
easy network-wide reconfigurations, without site visits.
● Scalable Management & Control
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.
● Plug & Play Integrated Design
● VSAT Groups, Traffic Engineering, and QoS
● ACM on Forward & Return Links
● Bandwidth Efficiency at Many Levels
With its high-order modulation options, 16-state Turbo
Code FECs, ACM, header compression, burst size opti-
mization, & intelligent capacity request algorithms, the
2900 delivers highly efficient broadband applications.
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.
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.
