Newtec MCX7000 Multi-Carrier Satellite Gateway

Uptime and reliability are essential in the design of the multi-carrier gateway, taking a vital role in the satellite network. Input source redundancy and the shortest redundancy switch-over times, operating both in 1+1 and N+1 topologies, are setting the standard in our industry.

Description

Newtec MCX7000 Multi-Carrier Satellite Gateway

Building upon the MDM6100 Broadcast Satellite Modem software suite, the enhanced hardware platform of the Newtec MCX7000 Multi-Carrier Satellite Gateway extends the modem capabilities beyond single carrier support. In a first release, three 133 MBaud carriers can be demodulated, next to modulation of a 133 MBaud signal with full support of the DVB satellite standards up to DVB-S2X. Each and every transport stream embedded in one of the received carriers can be output on one of the six (optional) ASI or dual Ethernet ports. The same data interfaces can be used as input ports for the modulator. Transmodulation of a received stream is also an option.

Its remote in-band management and software upgradeability makes it the receiver equipment of choice for remote unattended towers and headends. Subsequent releases of this future-proof DVB-S2X platform guarantee, by simple software upgrade, even increased functionality and higher density.

Delivering the highest uptime for vital links

MCX7000 Rear Panel

Advanced capabilities are built in such as a MPEG Transport Stream analyser, support of SMPTE 2022 FEC at the GbE inputs (for distributed IP headends), and native support of Carrier ID according to the new DVB standard as well as in the transport stream NIT Table. Special care was taken to cope with jittery transport stream over IP inputs. The 6 ASI ports are programmable as inputs or outputs allowing for monitoring as well as operational ASI ports.
