Packet Data Ip Addressing; Pd User Authentication; Tetra Network Protocol 1; Table 7: Packet Data Ip Addressing - Motorola MTP830 S Product Information Manual

• UDP packets not addressed to the WAP nor the GPS ports are routed to the PEI (using PPP).
Note: When activating another PD context on the radio, use the same settings in both PD contexts.

PD User Authentication

The PD user authentication is a method of authenticating the Terminal Equipment user before allowing the packet
data link activation. A PD Authentication server connected to the SwMI performs the actual authentication. The
terminal only sends the messages between the Terminal Equipment and the SwMI. In the wide mode, the terminal
offers PPP user authentication between Mobile Terminal and Terminal Equipment using Password Authentication
Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP), before the IP link is established. The
terminal always attempts to negotiate usage of the CHAP method. However, the radio agrees to use PAP, when the
Terminal Equipment application insists. If the terminal does not require PD user authentication, it operates without
any user authentication. However, if the terminal requires the PD user authentication, it rejects the Packet Data
Protocol (PDP) context activation.
Note: If the SwMI does not agree for the authentication method (for example, PAP), the SwMI can reject
it.

TETRA Network Protocol 1

TETRA Network Protocol type 1 (TNP1) is a bridge protocol based on the TETRA layer 3 over the air protocol. The
TNP1 supports all TETRA dispatch functionality.
Description
An IP address may be assigned to the terminal by the
SwMI during the Packet Data context activation. When
assigned, both Terminal Equipment and Mobile Terminal
applications use this address as the source address in IP
packets delivered to the infrastructure.
By default both Terminal Equipment and the radio have
their own IP addresses. Terminal Equipment and Mobile
Terminal use these addresses for local datagram trans-
missions between Terminal Equipment and Mobile Ter-
minal only and are not passed to the SwMI.
The terminals support static and dynamic IP address as-
signment. The dynamic support is requested in the fol-
lowing situations:
• Request a Dynamic IP Address is set to Dynamic
and the PD Application Type is the radio internal PD
application.
• Request a Dynamic IP Address is set to Dynamic
and the PD Application Type is a PEI PD application
requesting dynamic IP address.
