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

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).
