Connect an SSG Device to an Untrusted Network
Figure 5 shows basic network cabling connections for a device. This figure shows
two blank PIMs and the 10/100 Ethernet ports are cabled as follows:
„ The port labeled 0/0 (ethernet0/0 interface) is connected to the untrust
network.
„ The port labeled 0/1 (ethernet0/1 interface) is connected to a switch that
connects workstations on the DMZ LAN.
„ The ports labeled 0/2 through 0/4 (ethernet0/2 through ethernet0/4 interfaces)
are connected to a switch that connects workstations to the trusted network.
„ The console port is connected to a serial terminal for management access.

Connect Mini PIMs to an Untrusted Network
This section explains how to connect the device mini PIMs to an untrusted network.
Connecting the ADSL2/2+ Mini PIM
Connect the provided ADSL cable from the ADSL2/2+ mini PIM to your telephone
outlet. The ADSL port on the Annex A version of the device uses an RJ-11 connector,
while the Annex B version uses an RJ-45 connector. In the case of Annex B models,
the cable you connect from the ADSL port to the telephone outlet is identical in
appearance and wiring to a straight through 10 Base-T Ethernet cable.
Connecting Splitters and Microfilters
A signal splitter divides the telephone signal into low-frequency voice signals for
voice calls and high-frequency data signals for data traffic. Your service provider
usually installs the splitter as part of the equipment that connects your site
telephone lines to the provider network.
There are also splitters that you may be able to install yourself, depending upon
your service-provider equipment. If you are installing such a splitter yourself,
