Chapter 2 Installation
Installing the Router
Connect an Analog Telephone or Fax Machine (Cisco 827-4V Routers Only)
You can connect as many as four devices such as analog push button telephones or fax machines to a Cisco 827-4V router. Each device is connected to basic telephone services through the color-coded gray phone ports.
To connect an analog telephone or fax machine, follow the steps in Figure 2-6. You must provide the telephone cable for connecting each device. The telephone cable is usually provided with the device.

2. Connect other end of cable to telephone or fax machine.
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.
The gray phone ports are RJ-11 connectors. If you are outside North America, you must buy and attach adapters that allow telephones or fax machines to be connected to these RJ-11 connectors. In some countries, these adapters need additional electronics so that the telephones or fax machines will 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 2-4.
