characters, and it can be up to 60 characters
long.
Connectivity
Nailed-Up

connection if there is little traffic through the interface or if it costs money to keep the

Messaging Service)) and charge method.

Dial String
Enter the dial string if your ISP provides a string, which would include the APN, to
initialize the mobile broadband card.

readily available on more platforms.
Use the drop-down list box to select an authentication protocol for outgoing calls.
Options are:
None:
No authentication for outgoing calls.
CHAP
- Your USG accepts CHAP requests only.
PAP
