AMT-70/AMT-73/AMT-75 Installation and Operation
HSSI (High Speed Serial Interface) is also available: the base AMT-70 supports HSSI operation up
to 60 Mbps (higher speeds are available with option cards). The DVB/ASI interface can also be
supported. Two ASI connectors are provided; one for the modulator data input and one for the
demodulator data output.
The Modem can be controlled and monitored via a variety of protocols from simple RS232, RS485
or Telnet Command Line Interface (CLI), RS485 Packet Protocol, SNMP via Ethernet or Web-
server.
The AMT-70 series modems are powered from a universal power supply with a range from 96 to
263 VAC, 47-63 Hz. The modem is also capable of powering an LNB/BDC (24 VDC, 0.45 A) if this
power supply is fitted.
Finally, the standard BUC power supply produces 24 VDC at a maximum of 3.5 A (Max 110 W).
Optionally, the BUC power supply can be upgraded to 48 VDC, 2.2 A.

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 EIA/TIA-449 interface (37-D-sub connector).
HSSI (High Speed Serial Interface) is also available: the base AMT-73L supports HSSI operation up to
52 Mbps (higher speeds are available with other option cards). The AMT-73 series are powered from a
universal power supply with a range from 96 to 263 VAC, 47-63 Hz.
