The typical features of the modems include:
L-Band output of 950-1750 MHz, optional to 2000 MHz;
L-Band input of 950-2150 MHz tunable in 1 Hz steps
Optional IF interface: 70+/-18 MHz or 140+/-36 MHz
Provision of DC power and reference for Low Noise Block Down Converter (LNB) / Block
Down Converter (BDC) and Block Up Converter (BUC)
FEC: RSV (both Intelsat and DVB-S/DSNG), eTPC and DVB-S2(AMT75)
BPSK/QPSK/8PSK/16QAM/OQPSK/16APSK modulation
FFT Technology for reliable acquisition
Occupies 1 Rack Unit (RU) of Rack Space (1.75”)
Power Consumption less than 60 W (not including BUC power supply)
Full Monitor and Control Capability using a VT100 type (RS-232) terminal, Telnet, FTP,
SNMP (10/100 Base-T Ethernet), and command mode (RS-485).
Optional 48 VDC input power
Optional BUC power supply voltages and currents
ASI (Digital Video), RS-530, 10/100 Base-T Ethernet, Telecomm E1/T1 and HSSI data
interfaces supported
AMT75 series includes DVB-S2 and LDPC coding both Short(16k) and Normal(64k) blocks
On the back panel, there are 10/100 Base-T Ethernet, RS-232 and RS-485 serial bus (M&C)
interfaces. An Alarm/Relay connector provides simple redundancy switching capability.
The modem’s standard data interface is a synchronous RS-530 interface (25-pin D-sub connector).
Through the use of interface cables, the data port can be converted to a synchronous RS-530/422
interface (37-pin D-sub connector) or a V.35 interface (34-pin Winchester connector).
