To implement remote access on GPRS, each component connected to the network must know the public IP address(static) or the name of all components connected to the system. These
components are: the operator workstations and the TSX ETG 302X remote terminal units. On a GPRS network the public IP addresses are provided by the ISP (Internet Service Provider).
With a standard mobile Internet subscription, the ISP renews the public IP addresses periodically. These types of addresses are called dynamic public IP addresses. To
assign one of these as a static URL (Uniform Resource Locator), you can use a dynamic Domain Name System. The TSX ETG 302X module embeds a DynDNS client,
using DynDNS the URL names are pre-formatted, for example: xxxx.dyndns.info.
