At any time, you can save the current configuration settings as a file 
(Tools > Tools > Configurations). This is stored in the 

base station

, but you 

can 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.

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 40 ms 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.

If the 

base station

 is a control channel, the channel group settings should 

specify fixed marshalling and allow a duration of 40 ms. This gives the 
control channel’s transmitter an appropriate buffer (control channels do not 
use the preamble to regulate the transmit buffer). Marshalling duration does 
not apply to traffic channels.

Single 

base stations

 need a control connection to their site controller. A 

single 

base station

 interfaces to the site controller in the same way as the
