5.2.2 PSTN/PABX Gateway (TMO Only)
If the radio is configured with multiple gateway addresses, you can select the call gateway and the message
gateway.
Tap , tap PSTN gateway or PABX gateway, and then set the gateway information.
5.2.3 LA Application (TMO Only)
5.2.3.1 Associate Folder with Fixed LA
A folder can be associated with a designated LA, and a LA allows association of multiple folders. This
ensures that the radios participating in a call can quickly register to the designated LA, making full use of
channel resources in the area.
If the radio is configured with the Associate Folder with Fixed LA feature, when you switch the folder, the
radio switches to the associated LA for registration and stays in the LA until you switch to another folder.
5.2.3.2 Preferred LA
The radio can preferentially register to the designated LA according to the preset preferred LA list and the
switch strategy.
You can configure the frequently used LA to the preferred LA list. The preferred LA has the following three
strategies:

Normal Behavior: The radio preferentially registers to the LA in the preferred LA list.

Register to Preferred LA Immediately: If the radio registers to a non-preferred LA, the radio immediately
switches to the preferred LA when the following occur:
The radio detects a preferred LA in the neighbor cell, and the switch condition is met.

Only Permitted Register to Preferred LA: The radio registers only to the LA in the preferred LA list.
5.2.4 GSDM (TMO Only)
With the Graceful Service Degradation Mode (GSDM) feature enabled, when the signal is weak or no LA is
available, the radio can still receive group calls, initiate or receive emergency calls, and send or receive
emergency status messages.
If this feature is disabled, the radio will be out of service when the signal is weak.
