In addition to the traditional monitoring and control of the CDM-570\/L-IP modems and the CDD-564\/L and CDD-562L demodulators, the VMS allows these devices to share bandwidth, and when needed, switch automatically to a dedicated SCPC channel. In a Vipersat-powered network, the CDM-570\/L-IP modem takes advantage of its fast acquisition demodulation to allow it to operate in a shared mode. Inbound transmissions (from remote to hub) can be switched from a shared Selective Time Division Multiple Access (STDMA) mode to a dedicated Single Carrier Per Channel (SCPC) connection via a variety of user defined policies or triggers. This enables the network to more effectively handle real-time connection-oriented applications and reduces both latency and network congestion. Through VMS, dynamic point-to-point mesh connections can also be established between remotes.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eUpstream Switching\u003c\/b\u003e\u003cbr\u003eThrough protocol classification in the remote terminals, the modem initiates automatic switching. VMS establishes dSCPC bandwidth based on policies that can be individually enabled on a per-remote basis, or globally enabled. Policies can be configured for a variety of applications such as VoIP, video (VTC), or based on a load, or via a schedule, Type of Service (ToS), or QoS rules such as IP port or IP address and protocol type. Operators are able to set minimum and maximum data rates for each remote as well as excess data rates for an initial upstream switch.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eVipersat Operation Mode\u003c\/b\u003e\u003cbr\u003eVipersat operation is enabled via a FAST feature code.

Even under deep fade, ACM may be able to maintain the link at the lower MODCOD thereby increasing availability. It is tightly integrated with packet processor QoS which allows higher priority, mission critical traffic to be maintained even during fade.\u003c\/p\u003e\n\u003ch3\u003eLOW DENSITY PARITY CHECK CODES (LDPC) \u0026amp; TURBO PRODUCT CODES (TPC)\u003c\/h3\u003e\n\u003cp\u003eCDM-625A offers an integrated LDPC and 2nd Generation TPC codec.

DoubleTalk Carrier-in- Carrier, based on patented “Adaptive Cancellation” technology, allows transmit and receive carriers of a duplex link to share the same transponder space. DoubleTalk Carrier-in-Carrier is complementary to all advances in modem technology, including advanced FEC and modulation techniques. As these technologies approach theoretical limits of power and bandwidth efficiency, DoubleTalk Carrier-in-Carrier utilizing advanced signal processing techniques provides a new dimension in bandwidth and power efficiency.\u003c\/p\u003e\n\u003cp\u003eThe extensive list of software options allows for configuring the modem for today's needs while covering tomorrow's plans. These options can be purchased and then activated in seconds via the front panel. Additional hardware options like Turbo Product Code (TPC), interface expansion, high-stability and DC operation complete the modem's dynamic feature coverage.\u003c\/p\u003e\n\u003cp\u003eThis modem can be stocked at its minimum configuration (and cost) locally for immediate distribution.
