telephones, faxes, or modems to work properly with the router phone ports. For example, in the
United Kingdom, you must buy an adapter that also provides a master socket, which causes incoming
calls to ring the connected devices. For information on recommended master sockets, see Table 2-3.
Warning
This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do
not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11
port, or the associated circuit-board when the ringer is active. The ringer is activated (indicated by a
clicking sound) by an incoming call.
Caution Do not connect the router telephone ports to the telephone wall jack. These ports are not meant for direct
connection to a public network. This connection can damage your router.
