Network Example

Figure 1-3 illustrates a network that includes a Cisco 1400 series router.

A Cisco 1401 router connects to the ADSL line through a DSL modem. (The Cisco 1407

and Cisco 1417 routers do not require the modem.) Some DSL modems have an integrated

POTS splitter, which connects a phone or fax machine to the same ADSL line as the router.

If you are using a telephone and the Cisco 1407 or Cisco 1417 router on the same telphone

line, an external POTS splitter is required for optimal performance. A splitter reduces

possible interference on both data connections and voice calls, which use different

frequencies. For more information, refer to the “Using POTS Splitters and Microﬁlters”

section in the “Installation” chapter later in this guide.
