The NTC/2277.xF has been designed for the broadcasting, contribution or distribution of digital television signals as well as the transmission of high-speed TELCO data in backbone infrastructures and data content distribution networks. The NTC/2277.xF has two physical input interface positions that can be fitted with a range of interface modules: A DVB (ASI, SPI, LVDS) and a TELCO (HSSI/G703) interface module provide a standard data input to the modulator. The ASI concentrator module combines 4 ASI inputs for transportation of multiple ASI streams. The NTC/2277.xF can be fitted with any combinations of these cards. An IP GbE interface is also available. This module has an RJ-45 input and 2 ASI inputs/outputs. (*)
The DVB-S2 modulator NTC/2277.xF handles symbol rates from 0.05 up to 68 Mbaud, using a QPSK, 8PSK, 16APSK or 32APSK modulation scheme. The roll-off factor is selectable between 0.2, 0.25 or 0.35 in both DVB-S and DVB-S2 mode.
The NTC/2277.xF is standard equipped with an IF-band output. An L-band monitoring output is provided for connection of e.g. an IRD or spectrum analyzer. Optionally, the NTC/2277.xF can be equipped with an additional L-band output. A programmable digital equalizer is provided to compensate for external amplitude slopes. All Control and Monitoring parameters are available locally on the front panel (LCD display & keyboard) and remotely through a web interface (Http) or through the RS-485/232 port or through the 10/100 Base-T Ethernet port. The last two use the RMCPv2 protocol. There is optionally an SNMP + MIB agent. A dual contact closure output is available for 2 types of summary alarms: one contact is operated in case of device alarms, while the other contact opens (or closes) in case of input or output interface alarms.
