Type Drop Down Menu

The Type drop down menu, shown in Figure 117 identifies the type of call for Sepura radio configuration.

Trunked GC (Group Call) –

A half duplex point-to-multi-point call where immediate

 

communication takes place between the calling and the called users.

Trunked HDPC (Half Duplex Private Call) –

A half duplex point-to-point call between caller and called units. Each

 

unit asks permission to transmit before each transaction.

Trunked UDSL (User Defined Scan List) – A scan of specific groups predefined in the radio and in the IP-223. A UDSL is a collection of pre-defined talk group (or function tone) settings. The UDSL string entered in the ISSI/GSSI Number field is separated by the semicolon. It can accept up to 10 trunked groups.

Direct GC –

Communication with other TETRA radios without the use of the network. This

 

is called DMO (Direct Mode Operation).
