GSM option
The MDT-400 can incorporate an
internal GSM
module.
By default, the equipment will work with the TETRA network, and when it detects that it is not
possible to operate under TETRA, it
automatically switches
(if the equipment is configured in
this way) to GSM mode.
It is also possible to select
GSM mode through the menu
, accessing the
Working mode
submenu from the
Main Menu
. This screen shows the options V+D, DMO, DMO-GATE and
GSM, not allowing direct changes between GSM <-> DMO.
While the equipment operates in GSM, TETRA services will remain active: If TETRA calls are
received, they are rejected with the “User called engaged” cause. The messages received are
stored in the memory and can be consulted on returning to TETRA.
As soon as the equipment detects the recovery of TETRA coverage, it again returns to this
mode.
