STM SatLink 2900 Mobile User manual

The SatLink 2900 Mobile VSAT provides the
advanced capabilities required for land, sea, and
aerospace deployments, including global roaming
with access to 10 different beams for continuous
two-way satellite communications. Internet access,
Voice over IP, GSM over IP, and video conferencing
are common applications of its powerful mobile
features.
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 Mobile
Broadband Mobile VSAT Indoor Unit
The SatLink 2900 delivers 50 Mbps of download IP
throughput for broadband services using either Band-
width-on-Demand or SCPC mode and the highest
spectral efficiency. Its mesh networking option has low
-blocking probability with its ability to receive 8 concur-
rent 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
●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.
The SatLink 2900 Mobile VSAT can store parameters for
up to 20 Forward Links, enabling it to move seamlessly
between beams. The software is specially adapted for
the constant roll and pitch of the seas making it less
susceptible to outages, and the unit is equipped with a
GPS interface for fast, automatic logon and synchroni-
zation. Optional transmit inhibit switch prevents inad-
vertent transmissions outside of authorized areas. Mesh
networking option available for direct communications
between mobile installations.
●Adapted to Mobile Environment
Software for automatic beam switching is included for
interfacing with leading maritime & land mobile
antennas via IP.
