primary DNS address
As with personal computers that access the Internet, modems using CDPD technology
must also have access to a Domain Name Server (DNS). The DNS translates Universal
Resource Locators (URLs) such as World Wide Web addresses or domain names into IP
addresses and is shared by multiple devices. In order to get the translated IP addresses,
the modem will try to connect to the primary DNS. If the modem cannot connect to this
address, it will try to connect to the secondary DNS.
push messaging
Push messaging is a technology that allows you to receive notification of a waiting mes-
sage through the Wireless IP network without having a PPP session open. Auto power-off
mode must be disabled for this feature to work.
registration
In order to send and receive data across the Internet, a CDPD modem must first register to
the CDPD network. This involves selection of an appropriate channel to use and interac-
tion with various systems in the CDPD network to set up a path for communication.
scanning
The Minstrel 540 will look for the best cellular channel to use for data transmission by
scanning through the channels. This involves measuring the signal strength of various
channels to determine which is the strongest and, therefore, most reliable.
secondary DNS address
As with personal computers that access the Internet, modems using CDPD technology
must also have access to a Domain Name Server (DNS). The DNS translates Universal
Resource Locators (URLs) such as World Wide Web addresses or domain names into IP
addresses and is shared by multiple devices. If the modem cannot connect to the primary
DNS, it will try to connect to the secondary DNS.
service provider
The Minstrel 540 modem works with the Wireless IP network. To access the Internet using
this network, an account with a service provider must be set up. For information on avail-
ability and rates, contact a service provider in the area.
side
Each Wireless IP service area is divided into two sides, which are labeled A and B. A sin-
gle carrier or service provider is assigned to each side. However, the side associated with
a selected service provider may change with the service area.
