TCP/UDP IP Connection

Overview

The network capabilities are achieved by using different layers of connections. Every layer of
connections provides basic connections to the layer above it. The higher the layer is, the more
capabilities it can provide.
Figure 1-1: System Overview
The three layers of connections are:
•
Physical links
•
Point-to-point links
•
TCP/UDP links

TCP/IP

When establishing the TCP/IP connection the G24-L can only be the "initiator". The TCP/IP
feature enables the G24-L to be a wireless end point for a TCP/IP socket.
Note:
Creating TCP/IP Connections
Connection from the G24-L to the Web
The following occurs when creating a TCP/IP connection from the G24-L to the Web:
1. The G24-L connects to the GPRS network and receives an IP address (using the +MIPCALL
command).
