Hardware Description
5-12 80-99240-1 Rev. D
Power Consumption
Power consumption depends on a variety of factors such as
transmit power, input voltage, and data rate. Table 5-2
summarizes the power consumption of the GSP-1620 modem
at an input voltage of +12 V DC. All power estimates include
the DC power consumption of the ODU’s receive section.
The power modes in Table 5-2 are as follows:
• Shutdown — The modem is not operational in this state
and reverts to this state when DTR lines are inactive.
• Standby — The receiver section in the modem is active
during this time and the modem is ready to
transmit/receive data.
• Transmit — The modem’s transmitter is active in this
state and may be in the process of transmitting/receiving
data.
Power-On
Power-on is controlled via OR’d DTR signals from any port
(Data, Control or Diagnostic). When DTR is asserted on one
or more of the ports, the GSP-1620 modem powers up. Upon
successful power-up, the modem asserts the DSR line of each
active port to let the user know that it has booted up
successfully and is ready to accept commands. Only the Data
and Control ports include DSR lines.
