THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT
NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT
ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR
THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

For S1 or S2 service requests or if you do not have Internet access, contact the
Cisco TAC by telephone. (S1 or S2 service requests are those in which your
production network is down or severely degraded.) Cisco TAC engineers are
assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: [phone] (Australia: 1 800 805 227)

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has
established severity definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your
business operations. You and Cisco will commit all necessary resources around
the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or
significant aspects of your business operation are negatively affected by
inadequate performance of Cisco products. You and Cisco will commit full-time
resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most
business operations remain functional. You and Cisco will commit resources
during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product
capabilities, installation, or configuration. There is little or no effect on your
business operations.

Product Overview

The Cisco 836 router and the Cisco SOHO 96 router are asymmeric digital
subscriber line (ADSL)
devices. These routers have an integrated 4-port Ethernet switch for the LAN and
an ADSL physical interface for the WAN, and ISDN basic rate interface (BRI)
WAN connectivity. This ISDN BRI interface can be used for normal WAN
connections or can be configured as a backup connection for the ADSL WAN
interface. These features allow the routers to connect a corporate telecommuter or
a small office to a central office or an Internet service provider (ISP) over an
ADSL interface.

The routers support high-speed encryption, a 10/100BASE-T switch, and dial
backup functionality via the ISDN port. The autosensing function in these routers
eliminates the need for a crossover cable and allows the router to detect medium
dependent interface in normal mode (MDI) or medium dependent interface in
crossover mode (MDIX) in any other PC or hub with a straight-through cable or
a crossover cable. The routers are capable of bridging and multiprotocol routing
between the LAN and WAN ports.

The dial backup feature allows the user to connect the ISDN port to the ISDN
service provider as a backup link to the WAN in case the ADSL service goes
down. This feature gives the Cisco 836 and Cisco SOHO 96 routers a high level
of performance and security.

The Cisco 836 router is designed with both hardware-based and software-based
encryption, while the Cisco SOHO 96 supports only the software-based
encryption. The Cisco 836 router supports the addition of Flash or SDRAM
memory, as either a factory upgrade or a field-installed option. The
Cisco SOHO 96 router has a fixed memory configuration.

Warning

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits
to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits,
and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45
connectors. Use caution when connecting cables.

During this procedure, wear grounding wrist straps to avoid ESD damage. Do
not directly touch the backplane during with your hand or any metal tool, or you
could shock yourself.

This equipment is not designed for making emergency telephony calls when the
power fails. Alternative arrangements should be made for access to emergency
services. Access to emergency services can be affected by any call-barring
function of this equipment.

To reduce the risk of fire, use only No.26 AWG or large telecommunication line
cord.

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 by an incoming
call.

78-15281-02

Warning

Ths ISDN connection is regarded as a source of voltage that should be
inaccessible to user contact. Do not attempt to tamper with or open any public
telephone operator (PTO)-provided equipment or connection hardware. Any
hardwired connection (other than by a nonremovable, connect-one-time-only
plug) must be made only by PTO staff or suitably trained engineers.

Warning

Warning

Network hazardous voltages are present in the ISDN cable. If you detach the
ISDN cable, detach the end away from the router first to avoid possible electric
shock. Network hazardous voltages also are present on the system card in the
area of the ISDN port (RJ-45 connector), regardless of when power is turned off
(by pressing power switch to standby).

Ultimate disposal of this product should be handled according to all national
laws and regulations.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies
of different electrostatic potentials, such as an operator and a piece of electrical
equipment. It occurs when electronic components are improperly handled, and it
can damage equipment and impair electrical circuitry. Electrostatic discharge is
more likely to occur with the combination of synthetic fibers and dry atmosphere.

Always follow these steps to prevent ESD when you remove and replace
components:

Step 1 Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good

skin contact.

2-30

Caution To properly guard against ESD damage and shocks, the wrist strap and cord must

operate effectively.

Step 2 Do not touch any exposed contact pins or connector shells of interface ports that

do not have a cable attached.

If cables are connected at one end only, do not touch the exposed pins at the
unconnected end of the cable.
