At any time, you can save the current configuration settings as a file 
(Tools > Files > Configuration). This is stored in the base station, but we 
recommend that you download it and store it on your computer as an off-
site backup. The base station identity and network identity are not saved as 
part of the configuration file.

You may want to develop a master configuration and upload it to all base 
stations in the network. The master configuration can contain all the 
different channel configurations and can be common to all base stations. 
The base station identity selects the default channel.

Base stations are delivered with a default configuration which provides 
a safe set of values. We recommend that you download it and store it on 
your computer as a backup before changing and saving any configura-
tion settings.

Most base stations in non-simulcast trunked networks are single. They 
interface to a site controller but not to other base stations. The following 
explains the special considerations when configuring single base stations.

Although single base stations are not actually part of a channel group, their 
channel configurations (Configure > Base Station > Channels) must still 
select a channel group (Configure > Channel Group > Channel Groups). 

The selected channel group must be configured for single base station 
operation. Specify 127.0.0.1 as the channel group IP address. This stops the 
base station from attempting to send voice packets to other base stations.

Although the single base station’s transmitter does not receive voice 
packets from other channel group members, it still receives them from 
other base stations via trunking controllers. So, while most channel group 
settings have no effect, the preamble setting still applies and determines 
how large the transmit buffer is.

The default setting of 40ms is intended for internal jitter only. If the base 
station is a traffic channel, you may have to increase the preamble. Voice 
arriving at the base station’s trunking interface has travelled from another 
base station via the trunking site controller and could have significantly 
more jitter.

Although marshalling duration applies only to control channels, and has no 
effect on traffic channels, we recommend that you configure the 
marshalling duration for each base station as described below. This will 
allow any base station to operate as a control channel when required.
