Parameter Settings
* All simulcast base stations must be of the same frequency.
* Simulcast base stations need to connect together through IP or E1 link.
Multi-channel Connection
In a base station, when the number of channels is 2 or more, the channels are
connected through cables, as mostly seen in trunking base stations or DMR
pseudo trunking.
*Through row cable connection, channels are connected together. The bus slot
(Fig.1- ) has two rows, which respectively connect to the upper and lower
④
transceivers.
*Base station controller is generally used in multi-channel connection.
Dip Switch & Channel Number Settings
The settings of dip switch (see Fig.1- ) should be corresponding to the settings of
③
channel number of the network management terminal (see software instructions for
details). As for a single carrier channel, the corresponding method can be summarized
in this formula: channel number = Dip number * 2-2. The dip number can be set
according to the corresponding channel position.
