SDS services for Hytera infrastructures
The Hytera infrastructure is using the so called "ACAPI"-Interface to send and receive
SDS data and status messages by a direct IP connection to the TETRA infrastructure.
The TGW-100 supports the Hytera ACAPI interface from firmware 2.70.
If the Hytera infrastructure option is enabled in the TGW-100, the service can be
configured in the webserver at TETRA
Hytera Gateway:
Two independent ACAPI addresses can be configured: A primary ACAPI connection
and a secondary ACAPI connection. Below these settings, the use of the primary or the
secondary ACAPI connection can be selected. In addition to this, a switchover time
between 0 and 60 minutes can be configured for a redundancy switching.
If the switchover time is configured, the TGW-100 will automatically switch to the
other ACAPI address if the selected interface fails (i.e. if the SwMi is down). If this
setting is set to 0 minutes, no automatic switching will occur.
Please note that the TGW-100 will stay connected to the SwMi after the switching, it
will not automatically switch back to the previous used connection. If the TGW-100
should use again the old connection, it must be switched back manually. Of course, if
the second connection also fails, the TGW-100 will go back and try the first connection
after the switchover time has passed without a valid connection to the SwMi.
