TB7300 Installation and Operation Manual Connecting to the Base Station 41

Tait recommends that you download these configurations and store

them on your PC as a backup before altering and saving any of your own

configuration settings.

You can also generate a report containing all the base station’s

configuration settings relevant to the current application software (Tools >

Files > Configuration > Configuration report), which can be saved as a text

file. We recommend that you do this when the base station is

commissioned. This report can be useful later if there is a problem with the

base station. Comparing the original report with the later one may highlight

changes in configuration that are causing a problem.

4.4.5 Single or channel group base stations

Base stations can operate singly, or as part of a simulcast or voted channel

group. Channel group operation is enabled in the channel group profile:

(Configure > Channel Group > [name]), and the channel group that is in-

use is selected in the channel table (Configure > Base Station > Channels

> [name]). To disable channel group operation, deselect the ‘enable’ check-

box in the profile referenced by the channel. For more details, see the DMR

Simulcast and Voted Channel system manual.

4.4.6 Marshaling or transmit delay

As an IP connected base station, transmitters must buffer the signal to be

transmitted so that variations in delay in the IP network do not cause the

transmitter to underrun.

Non-simulcast channels use a configurable transmit delay. The amount of

transmit delay required varies with the QoS (specifically jitter) of the IP

transmission network.

Transmitters in a simulcast channel must all begin transmitting

simultaneously, therefore the configured value of the marshaling duration

must allow for the worst case network delay, including delay variation

(jitter).
