In the SatLink system the hub acts as the master of the MF-TDMA network by broadcasting one or more continuous mode TDM Forward Links to the VSATs in the network and controlling all timing in the network. In a star topology network the hub is also the traffic gateway to the terrestrial network. In a mesh topology network selected VSATs may become the primary traffic gateways and the hub's functions may be reduced to control and management.

SatLink hubs offer unprecedented versatility, scalability and reliability. Their principle components are designed and manufactured by STM and operate on software designed, developed and supported by STM directly (with the exception of standard networking elements such as IP routers, LAN switches, firewalls, etc. for which STM uses products from industry-leading suppliers.)
The SatLink product line offers a choice of two fully integrated hub systems, the SatLink Enterprise Hub System , intended for networks up to about 500 VSATs, and the fully-redundant, high-capacity SatLink Carrier-Class Hub System . Each of these comes in a standard configuration with various upgrade options. STM handles all final testing and integration of the hub into the network. In addition STM will integrate, test and install special or customized hub options and configurations to meet unique customer requirements.
These integrated SatLink hub systems include all necessary baseband and IF functions, such as: the Forward Link System (FLS), the Return Link System (RLS), IP routing, LAN switching, and timing/frequency references, plus the data-based driven SatLink Network Management System (NMS) and Network Control Center (NCC) software and hardware for optimum network performance and easy, comprehensive operational control. These include support for Virtual Network Operators (VNOs), multi-beam/multi-band networks, and, if required, mesh networking. Other value added options at the hub, such as TCP acceleration, traffic shaping/QoS on the Forward Link, advanced firewalls, and VoIP Gateways are also provided and integrated by STM as required by the customer.
Outdoor components for the hub system (e.g., antenna and RF amplifiers) are separate. Customers may use existing RF and antenna systems (if suitable), or STM can select, integrate and install the correct outdoor elements for the hub to meet specific customer requirements.
Customer's not wishing to have their own hub system may use STM's Global Teleport Services .
Customers that require their own hub, but cannot or do not wish to operate and manage all aspects of the hub and its VSATs may use STM's Managed Services .
