10. Traffic Initiated Logon
The SatLink Terminal can be configured to logon automatically to the DVB-RCS gateway when it has
traffic to send and logoff again when it has had no traffic to send for a configurable timeout period.
This mode is useful for terminal installations where low power consumption is important (e.g. when
powered by solar power and batteries). It is also useful in systems where it is desirable to reduce the
signalling bandwidth on the return channel (by avoiding use of dedicated SYNC slots when the terminal
has no traffic to send).
The power saving mode requires the use of the STM SatLink 403x transceiver or the STM SatLink 3000
transmitter. The power consumption will then be reduced from typically 27W to approximately 12W
when the terminal is logged off when using the SatLink 403x transceiver with SatLink 1000

.
The STM SatLink Terminal can be configured to use traffic initiated logon by typing the CLI command
dvb tx autostart traffic <timeout>
where
<timeout>
is the timeout in minutes the terminal
will wait before logging off when it has no traffic to send.
Example:
dvb tx autostart traffic 5
configures the SatLink Terminal to use traffic initiated logon and automatically log off the network after
not having any traffic to send for 5 minutes.
Verify the configuration of the transmitter mode and the timeout for traffic initiated logon by typing the
CLI command
dvb tx show

When using the STM SatLink 4033 transmitter with STM SatLink 1000 the power consumption will be
reduced from typically 30W to approximately 12W when the terminal is logged off.
