Juniper J-Series Administration Guide

Chapter 2
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 router from a remote location through
two modems over a telephone network. The USB modem is connected to the USB
port on the Services Router, and a second modem is connected to a remote
management device such as a PC or laptop computer.
NOTE: We recommend using a Multi-Tech MultiModem MT5634ZBA-USB-V92 USB
modem with J-series Services Routers.
You use either the J-Web configuration editor or CLI configuration editor to configure
the USB modem and its supporting dialer interfaces.
