Cellular modems must be activated before they can “talk” on the cellular network. Typically, the activation is done by the carrier. Some carriers use a proprietary PC client. In all cases, make sure that your modem works on your PC before using it on the W-600 Series.

NOTE: Verify your modem is activated and works with your Microsoft Windows or Apple Mac computers.

Each time a USB device is inserted, Linux assigns it a new USB address. This is true even if the same device is re- inserted. Modem ports are organized under their individual addresses. For example, ttyUSB0 at address 3 is separate than ttyUSB0 at address 7. The address is displayed when you execute the commands, show usb and show usb verbose (the Dev# field).

Configuring the Profile and Modem Driver

1.Insert the USB Modem into an open USB port.

2.Verify that the modem is detected (the show usb command. (see Figure 339.)

3.If your modem is not recognized (such as “type is unknown”, “no matching profile”, or “device not ready”), use the show usb verbose ( see Figure Figure 333) command to verify your modem is listed.

4.Create a cellular profile and import the identifiers.The Dialer, TTY, and Driver fields are the new profile defaults.

5.Configure the modem driver.

The default “option” driver is a catch-all for cellular modems. Nearly all cards use this driver and support for new modems are added here. Once option driver is configured to work with this device, it recognizes the modem and expose its ports. The following example has four serial TTY ports (option driver) and one flash device (usb- storage driver).
