The MSS Network consists of Briefcase Terminals and MSS Hub which provides central control for the Briefcase terminals operating in SCPC DAMA mode. It allocates the resources to the terminals on demand. The network supports voice & data and can be integrated to the existing networks through EPABX (E1, IP or PSTN lines).
NETWORK ARCHITECTURE & TOPOLOGY AN OVERVIEW
The deployment overview of the satellite Network consists of NCMS & briefcase terminals. NMS is meant for secure VSAT network that will be configured for Star topology. It follows an architecture that makes it independent of frequency bands. Overall network security is of prime concern. Its design is on the assumption that majority of the traffic will be thin route following Poisson distribution. This traffic distribution is best served by the circuit switched network and therefore, SCPC DAMA philosophy has been adopted.NMS system uses Frequency Division Multiple Access (FDMA) for multiple traffic channels and Slotted Aloha for Resource Reservation. This scheme gives fairly good advantage in terms of satellite bandwidth utilization over the pre-assigned connectivity.
