Some operational functions of the 

base station

 are controlled by licenses. 

These functions will not work unless you purchase the appropriate feature 
license and enable the feature set controlled by that license. The feature sets 
currently available are listed below.

Allows the 

base station

 to go into Online mode. 

Base stations

 are always 

provided with this license.

Allows a 

base station

 to participate in a trunking system. Without this 

feature, the 

base station

 cannot provide a control or a status connection to a 

trunking site controller and it cannot function as a control or traffic channel.

Allows the 

base station

 to act as a central voter within its channel group. This 

feature also allows voice networking. Only 

base stations

 that will centrally 

vote (normally the central voter and its backup) need this feature. The other 
members of the channel group only need the networking with distributed 
voter feature. A standard trunked 

base station

 (standalone without fill-in 

repeaters or other channel group members) can function as a master or a 
failsoft repeater without this license. 

This feature is required in 

base stations

 that have transmitters and belong to 

a simulcast network.

Allows the 

base station

 to transmit using the LSM modulation scheme. This 

scheme is designed to minimize performance degradation in simulcast 
channels caused by delay spread.

Allows trunked channels that become isolated from a site controller to 
perform simple conventional operation and to interface to a digital dispatch 
system. If a trunked channel consists of several 

base stations

 in a channel 

group, only the central voter (normally the master) needs this license. It is 
then able to become the failsoft repeater for that channel group. 

 

This feature will allow the 

base station

 to operate in trunking mode using 

two-slot TDMA as defined by the P25 Phase 2 standard.
