IP Addressing for the GSP-1620 Modem

The OEM or Service Provider must choose either a dynamic or fixed Internet Protocol (IP) addressing scheme, depending on the intended use of the GSP-1620 modem:

•If the modem is expected to be mobile and roam between Gateway service areas, a dynamic IP addressing scheme should be used. A new IP address may be assigned to the terminal equipment whenever a new packet data call is set up.

•If the unit is “fixed” in its position and no mobility is involved, either a dynamic or fixed IP addressing scheme can be used. However, if the unit is “fixed” in its position, no mobility is involved, and the user’s application requires a fixed IP address, then a fixed IP addressing scheme should be used.

The difference is that in a “fixed” addressing scheme the user’s application at a host site or server will always know the IP address of the remote DTE (SCADA application). In a “dynamic” addressing scheme, the IP address is not known until the remote SCADA application/modem and the host/server are in an active session. In both the “fixed” and the “dynamic” addressing scheme, either the SCADA application/modem or the host/server can initiate a call/IP session.

Dynamic IP Addressing

A dynamic IP address pool in the Gateway can be configured with either private IP addresses or globally routable IP addresses. Therefore, the type of IP address assigned to a dynamic IP user during call setup depends on the Gateway configuration. With a dynamically assigned IP address, the modem can roam to another Gateway and re-establish Packet Data service by having the system automatically assign a new dynamic IP address.

With dynamic IP addressing, the modem can initiate a call/IP session with the host/server. Once a session is established, the assigned IP addresses remain constant until the session is terminated. With the added capability of dormant mode
