Standby

Operating states / LED
In the network search state, the TC35
Terminal searches for a GSM network. All
the components in the GSM Terminal
(module) that are not required are shut down
in several stages by the energy-saving
software.
This state is reached:
• From the POWER DOWN state: by an
active ignition (on) signal at the power
supply connection or
• From the TALK or STANDBY state: when
the network is lost (out of range)
In the STANDBY state, the TC35 Terminal is
ready to send and receive and registered in
the network. Paging is performed with the
GSM network in order to obtain
synchronisation with the GSM network
(repetition rate dependent on the
BSPA_Mutiframe=2...9 parameter). All
the components that are not required are
shut down in several stages by the energy-
saving software. Power consumption in this
state depends on the current network
availability.

Talk

In TALK mode a connection has been
established between two subscribers via
the GSM network. Power consumption is at
the maximum and depends on the GSM
network availability and several connection
settings (e.g. DTX off/on, FR/EFR/HR,
hopping sequences and antenna coupling).
