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 INFORMATION
PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO
LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

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.

Back-to-Back Cabling (Cisco 633 and Cisco 673 only)

You can connect two Cisco 633s or Cisco 673s in a “back-to-back” configuration.
This allows one CPE to terminate the traffic of a second CPE without central
office (CO) equipment. This configuration can be used as a low-cost solution for
communicating between two locations at a distance greater than Ethernet’s

78-11190-01

Cisco 600 Series Installation and Operation Guide

2-5

Set Up the Hardware Environment

100-meter range. The two locations must be directly connected, for example,
through some internally owned telephone system wiring in a campus-type
environment.

Chapter 2 Installation Procedures

Step 1

At the first location, connect one end of the SDSL cable into the WALL port on
one of the Cisco 633 or Cisco 673 units. Connect the other end of the SDSL cable
into the wall jack.

Step 2

At the second location, connect one end of the second SDSL cable into the WALL
port of the second Cisco 633 or Cisco 673 unit. Connect the other end of the
second SDSL cable into the wall jack.

Step 3

Configure the CPE that you want to terminate traffic to operate in CO mode and
the other to operate in CPE mode. See the “Attention Back-to-Back Connection
Users” section on page 4-5 for more information.

Note

Back-to-back configuration works in bridging mode only.

POTS Splitter Configuration (Required for the Cisco 627)

A POTS splitter separates data signals from voice signals on your telephone line.
The POTS splitter works by running a separate data line from the voice line, so
that the CPE has a dedicated cable for data transmission. Figure 2-3, Figure 2-4,
and Figure 2-5 show telephone equipment connected to a POTS splitter.

Power On the CPE

Chapter 2 Installation Procedures

For the Cisco 627, connect the other end of the network cable to your premises
router, for example, a Cisco 3600 series router.

For the Cisco 67x, if the customer premises has only a single Ethernet-equipped
computer, attach the Cisco 600 series CPE to the computer’s Ethernet adapter
with the crossover cable provided. Otherwise, connect the Cisco 600 series CPE
Ethernet port to an Ethernet hub via a straight-through cable (not provided).

Step 3

Connect the telephone cable to the WALL port. Connect the other end of the
telephone cable in the appropriate configuration as discussed in the “

Configurations” section on page 2-5.

Step 4

(Optional step for the Cisco 678) Plug the microfilter into the PHONE port. Then
plug the telephone into the microfilter.

Note

Never connect a telephone directly to the PHONE port of the
Cisco 678; this affects the CPE’s performance.

Step 5

(Optional step for the Cisco 675) Plug the telephone into the PHONE port. The
telephone can be connected directly to the PHONE port of the Cisco 675 because
it uses a built-in microfilter.

Power On the CPE

Possible

Step 1

Connect power to the Cisco 600 series CPE by plugging the power supply into an
appropriate electrical outlet.

Note

Use only the Cisco-approved power supply that shipped
with the CPE as your power supply.

a specific virtual circuit along with the normal user traffic flow. The cell is
carried unmodified by each intermediate ATM switching node until it arrives
at the circuit's other endpoint such as the Cisco 627. The receiving endpoint
modifies the cell payload to indicate that the cell has been looped back and
transmits this new cell back into the ATM circuit. It is relayed by each
intermediate node until it arrives at the original transmitting endpoint. The
receipt of this cell indicates a valid end-to-end connection between the two
endpoints over the intervening ATM network.

Bridging Mode Procedures

When the Cisco 67x operates in bridge mode, it behaves like a wire connecting a
local PC directly to a service provider’s network. Bridge data is encapsulated
using the RFC 1483 or PPP (BCP) protocol to enable data transport. Because
bridges operate at the Media Access Control (MAC) layer only, applications
requiring IP communication, such as Telnet, TFTP, RADIUS, Syslog, Ping, and
the web interface, are not available unless a management VC is configured.

Cisco currently supports a learning bridge mode. The virtual path
identifier/virtual channel identifier (VPI/VCI) configuration of the Cisco 67x is
unaffected by the operational mode (bridging versus routing) of the device.

Cisco also provides two methods of configuring and managing the bridged
Cisco 67x, through in-band bridging management or through a separate
management VC. The two methods cannot be used simultaneously. If a separate
management VC is used, the Cisco 67x can only be managed remotely through
wan0-1 and not from the local network.

Chapter 5 Configuration Procedures for the Cisco 67x CPE Devices

Configure the WAN Ports and ATM Virtual Connections

Configure the WAN Ports and ATM Virtual
Connections

The Cisco 67x has two types of WAN ports: physical (wan0) and logical
(wan0-x). The physical WAN port connects the Cisco 67x to the wide area
network. The logical WAN port or ports allow you to create virtual WAN
connections for plural destinations. To configure logical WAN ports, you must
provision ATM virtual connections. The instructions for each are provided in this
section.

The Cisco 67x automatically trains up to the ideal line speed. By default, the
Cisco 67x is provisioned with the following rates:

Encoding Downstream/Upstream Rate (Mbps)

DMT 8.032/.864

CAP 7.168/1.088

G.Lite 1.536/.512

The maximum operative rate is determined by the central office ADSL equipment,
line length and line conditions.

On the Cisco 67x, the WAN0 port is always ready to send and receive network
traffic.You need to define an ATM virtual connection (VC), which might differ
from the default, when communicating across an ATM network. There are two
types of ATM connections:

Virtual paths, identified by virtual path identifiers (VPI)

•

Virtual circuit, identified by the combination of a VPI and a virtual circuit

•

identifier (VCI).

Because the Cisco 67x connects to the Cisco 6xxx series, the subscriber side
VPI/VCI settings are not seen by the ATM network. All subscriber side VCs use
VPI 1 and VCI 1 by default.

Cisco 67x comes preconfigured with one VC already established. Each VC is
expressed as WAN0-x, where x is a number between 0 and 3.

Set ScalaRate for wan0-x

ScalaRate is a technology developed by Cisco that allows dynamic allocation of
bandwidth within an ATM-based ADSL connection. This bandwidth allocation is
specified and controlled by the end-point devices without affecting the
provisioning or status of the underlying ATM transport VC. Bandwidth within the
ADSL connection is allocated on a VC basis and provides flexibility in rate
structures and deployment models for service providers and network

Step 1

The key features of ScalaRate are:

Applicable to individual logical WAN ports (wan0-x).

•

Sets maximum upstream rate per VC in the CPE, and maximum downstream

•

rate per subscriber in the central office equipment.

Can be set in increments of 64 Kbps.

•

Rounds down to the nearest 64 Kbps increment. For example, if you set the

•

rate to 68 Kbps, the setting will be rounded down to 64 Kbps.

Can be set for less than or equal to the maximum ADSL trained rate.

•

To set the wan0-x to ScalaRate:

To close the wan0-x port, enter:

set interface wan0-x close

where x is the port you want to close.

Create Routing Tables

In order to pass data through a network and onto the Internet or wide area network,
you might need to add the IP address(es) of gateway(s) to the routing table. Follow
the instructions below to build a routing table manually by adding or deleting
entries in the table.
