Key Features

Following are the key features of the Cisco 1400 series routers:

<<Reviewers: Do we need to add more features here for the lastest SW releases?>>

Terms

These are some key ADSL elements and terms you should know:

  The Cisco 1400 series router supports PVCs to establish an end-to-end connection to the remote device. The router does not support switched virtual connections (SVCs).

<<Reviewers: Are there any terms that should be added to this list?>>

Technology Overview

An ADSL line is a DSL that transfers data from the telephone central office to the user much faster than the user sends data to the telephone central office. ADSL is ideal for applications such as high-speed Internet access and video-on-demand, in which the server sends much more data than the client sends. Internet users, in general, download more information from the Internet than they upload.

One of the key features of ADSL is that it operates over existing standard telephone wires, enabling simultaneous voice and data transmissions over the same telephone line.

ATM over ADSL

The Cisco 1400 series routers use ATM over ADSL to transfer data to and from remote networks, such as an ISP or corporate network.

By using ATM, the router can maintain a communication session with the remote location until the session ends. A continuous connection results in a higher quality of service than that of many other data protocols.

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.

Additional Required Equipment

Table 1-5 is a list of other equipment that you need to completely install your router.


Table 1-5: Additional Requird Equipment
Equipment When You Use It

10BaseT Ethernet hub or 10BaseT Ethernet switch

Hubs and switches connect multiple pieces of network equipment (including the Cisco 1400 series router) to create a network.

You need either a hub or switch, not both, to connect your router to the LAN.

ATM-DSL modem
(Cisco 1401 router)

An ATM-DSL modem (for example, a Cisco  625 or Cisco 626) connects ATM-based devices (such as the Cisco 1401 router) to ADSL lines.

Some DSL modems include an integrated POTS splitter, which connects the router and a telephone or fax machine to the same ADSL line.

If you are not sure what type of DSL modem to use with your router, contact your ADSL service provider or your Cisco reseller.

RJ-11-to-RJ-11 cable
(Cisco 1401 router only)

This cable connects a DSL modem (used with the Cisco 1401 router) to the ADSL line. You might need to provide one if it is not included with the modem.

POTS splitter
(Cisco 1407 and
Cisco 1417 routers)

Optimal router and telephone performance (when the router and telephone are used on the same telephone line) requires a POTS splitter. A splitter reduces interference that might occur on data connections and voice calls. Some types of splitters can be used to connect analog devices, such as a telephone or fax machine, to the same ADSL line as the router. For more information, refer to the "Using POTS Splitters and Microfilters" section in the "Installation" later in this guide.

If you are not sure what type of splitter to use, contact your service provider or your Cisco reseller.

Microfilter(s)
(Cisco 1407 and
Cisco 1417 routers)

Microfilters can be used (in addition to a POTS splitter) to further reduce interference on a voice call. Refer to the "Using POTS Splitters and Microfilters" section in the "Installation" later in this guide for detailed information on when to use microfilters with the Cisco 1417 router.

If you are not sure what type of microfilter to use, contact your service provider or your Cisco reseller.
