50 | Services and Features
In the TMO, the TNP1 specifies a protocol for use over the PEI, that allows terminal equipment (TE) to have control
over the TETRA services: mobility management, call control, short data service, and supplementary services: send
GPS reports, software information and battery state information. In addition, commands to access the radio
configuration and storage parameters are available.
The radio supports TETRA standard packet data using the IP network layer protocol.
The radio can operate both on the single slot packet data channel and the multi-slot packet data channel.
Packet data applications reside internally, for example: GPS reports, WAP, or in an external device connected to the
8–wire RS232 data port on the radio. Communication to the external device is initialized using AT commands.
The system provides point to point IP connectivity allowing the following datagram exchanges:
• Radio ←→ External Equipment (TE) (for example PC).
• External Equipment (TE) ←→ Network (through radio).
The radio supports IP version 4 packet.
TNP1 services can use one of two PPP methods to connect from the terminal equipment to the radio, local mode, and
wide mode. The TNP1 should be used in wide-mode wherever possible, to allow the parallel operation of TNP1-SDS
services and packet data services over a common PPP link.
If the transmit inhibit is entered, the radio drops the wide mode connection, thus the PEI goes back to AT mode. Then
the TNP1 client detects this change and reinitiates the PPP session in local mode.
The radio disables the TNP1 session while being in the DMO.
AT commands are used to initiate the PPP service for TNP1 to operate. Once the PPP session is running all AT
commands are blocked. When the PPP session is closed, AT commands are available.

Mobility Services

Following is the description of the Mobility Services.

Main Control Channel Frequencies

The radio can find a wide range of main control channels. The radio maintains stored lists of carrier frequencies
which are scanned in order.
1 A dynamic list of up to 32 discrete entries maintained only by the radio software.
2 A static list of up to 32 discrete frequencies specified by the operator that can be preprovisioned. The system
operator can modify this list using the programming tool.

Description
All TNP1 services are available including packet data
transfer towards the SwMI. The address used is the dy-
namic address MS IP or configured statically.
All TNP1 services are available except packet data trans-
fer. The addresses used are the two static addresses TE
IP: 10.0.0.101 and MT IP: 10.0.0.100.
The radio uses a fixed port address for reception and
transmission of TNP1 packets. The port number is 4024.
