208 Part I: Task Manager
© Tait Electronics Limited December 2007
Note: When a base station is reset, it reverts to its default channel.
Example
IF Tone 2 detected THEN Reset base station
This task means that a technician can remotely reset the base station by sending
a radio signal with the appropriate subaudible signalling.
Transmitter actions
Transmitter override actions can enable, disable, or toggle the Transmitter
system flag. This provides you with an additional layer of control over
transmitter operation.
When the base station enters Run mode, the flag is enabled.
When the Transmitter system flag is disabled, the transmitter cannot transmit.
When the Transmitter system flag is enabled, the transmitter operates as usual.
If the PMU is fitted with a standby converter and the Receiver and the
Transmitter system flags are both disabled, the PMU shuts down as in Deep
Sleep mode.
Note:
You can shut down specific forms of the transmitter
operation. See “Talk Through Repeater Actions” on page 211 and
“Line-Controlled Base Actions” on page 211 .
Receiver actions
Receiver override actions can enable, disable, or toggle the Receiver system
flag. This provides you with an additional layer of control over receiver
operation.
When the base station enters Run mode, the flag is enabled.
When the Receiver system flag is disabled, the receiver is always muted. If the
current channel profile enables tone on idle, an idle tone is output on the line.
When the Receiver system flag is enabled, the receiver operates as configured.
If the PMU is fitted with a standby converter and the Receiver and the
Transmitter system flags are both disabled, the PMU shuts down as in Deep
Sleep mode.
External channel select actions
External channel select override actions can enable, disable, or toggle the H/W
channel select system flag. This provides you with an additional layer of control
over how the current channel is selected.
When the base station enters Run mode, the flag is enabled.
When the flag is disabled, the channel is specified in software (Configure > Base
Station > General). The base station uses the default channel.
When the flag is enabled, the channel is specified by the Channel select lines
connected to the system interface card. The system interface must be configured
using the Service Kit to enable channel selection.
Note:
Other Task Manager actions can tell the base station to change
to a different channel.
