The Implications of the Internet of Things for Education

teacher-educationFor years, experts have predicted that the Internet of Things—a system in which objects can communicate internally or with other machines—will transform the way we live our lives. As it turned out, some of those prognostications were a bit premature. In 2014, however, I fully expect the IoT to be a much more mainstream concept.

 Q: What is Dial Backup?
How do I setup Dial Backup?

At its simplest, dial backup (DBU) is designed to dial the original phone number that the attached terminal dialed if the IPG is unable to connect to the TCP/IP host. Example: a POS terminal on port Terminal1 dials 555-1212. This number is translated to TCP host somehost.com:1234. The IPG attempts and is unable to connect to the TCP host. So the IPG opens the modem port, dials the original number (555-1212) then passes all the data, untouched, back and forth between the Terminal1 port and the Modem port until one side hangs up.

Alternatively, you can configure a Dial Backup number in the Phone Number Translation table or in the Host Protocol definition. In this case, the specified DBU number will be used instead of the originally dialed number.

For detailed setup insructions, see Dial Back-up Documentation in the Application Notes section..
