SatLink Hub Family

SatLink Hub Family for TDM/TDMA & SCPC Satellite Networks

SatLink hubs provide the high-performance modems, IP gateway, management and control functions for all SatLink Communications' VSAT networks. They implement a TDM/TDMA network in accord with DVB-S2 and DVB-RCS2 standards, offering bandwidth on demand, ACM, and QoS on all carriers, while delivering excellent efficiency, throughput, scalability, and reliability. SatLink also has an optional SCPC mode for added flexibility. The hub design employs SatLink Communications' Open Hub Architecture using a common set of modules that ease growth and re-configuration. All SatLink networks are fully managed by the SatLink NMS.

A full range of SatLink hub configurations are offered from small portable hubs to carrier-class high-availability Hubs with 99.999% uptime. Hubs configured with redundancy in key modules can be upgraded with minimal or no disruption to traffic flows.

SatLink Communications is the leader in DVB-RCS and DVB-RCS2 networks including: VSATs, hub systems and hub components, with value-added options and advanced QoS for data, voice, and video networking. SatLink Communications supplies ISPs, governments, enterprises and partners around the world, offering turnkey integration, installation, 24x7 global support and managed network services.

Features and Benefits


Bandwidth Efficiency at Many Levels

The efficiency of DVB-S2 forward links is matched with DVB-RCS2 return links offering ACM per burst, adaptive carrier selection (ACS), return carrier, multiple layers of header compression, and the most efficient IP encapsulation, with TDMA management that assures no wasted bandwidth.  

Advanced Traffic Shaping with QoS

Advanced traffic shaping on forward and return links with four QoS classes meet the strict requirements for  jitter and/or delay sensitive VoIP, video conferencing, video streaming, and time critical data applications.


Software-Defined RLS and FLS Platform

The FLS and RLS use SatLink Communications' own software-defined modem platform optimized for processing both IP packets and the DVB standard waveforms, using SatLink Communications' firmware and software running on FPGAs and CPUs. They deliver many cost reductions and operational benefits, including: high-efficiency MODCODs, large TDMA carrier groups, fast-feedback ACM integrated with IP QoS, and custom configurations of carrier groups for maximum efficiency in burst-mode operation and space and power savings.


High Availability for Maximum Uptime

Module redundancy using 1:1 or N:1 with fast failover. Geographic redundancy with multiple RF systems. SW updates on-the-fly. Uptimes can exceed 99.999%. 


Return SCPC Mode for Added Flexibility

An optional SCPC Mode enables the simplicity and spectrum efficiency as required for large high-capacity, dedicated trunks for an adaptable, complete solution.


ACM, ACS and Rain Fade Mitigation

With adaptive coding and modulation (ACM) applied on both forward and return links and ACS on all TDMA carriers, the impact of rain fades is greatly mitigated, even in Ka-band.


Traffic Engineering, VNOs and VSAT Groups

SatLink’s traffic engineering enables cost-effective hub sharing by controlling bandwidth consumption and QoS policies of virtual network operators (VNOs) for each of their VSAT groups, without assigning hardware or dedicated carriers to particular VNOs.


Comprehensive NMS and NCC Software

SatLink Communications' database-driven SatLink Network Management System (NMS) and the SatLink Network Control Centre (NCC) software optimize network performance using close-loop control and simplify the configuration and provisioning of hub modules, VSATs, VSAT groups, carriers, VSNs and VNOs. Support for multiple beams, across multiple satellites on multiple bands (C-, Ku-, Ka-, EHF), including cross-strapped transponders, adds versatility and scalability.
