Setting Up USB Modems for Remote Management

J Series Services Routers support the use of USB modems for remote management. You can use Telnet or SSH to connect to the device from a remote location through two modems over a telephone network. The USB modem is connected to the USB port on the device, and a second modem is connected to a remote management device such as a PC or laptop computer.

Note: We recommend using a US Robotics USB 56k V.92 Modem, model number USR Model 5637.

You use either the J-Web configuration editor or CLI configuration editor to configure the USB modem and its supporting dialer interfaces.

For information about which devices support the features documented in this chapter, see the Junos OS Feature Support Reference for SRX Series and J Series Devices.
