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 di gital 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 pr obabl y 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 Ci sco Systems, Inc. could void the FCC approval and negate your auth ority to op erate the product.

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test ou r products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:

• For Emergencies only — security-alert@cisco.com

URL:

An emergency is either a condition in which a system is un der acti ve attack or a condition for wh ich a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your netw ork is minimally impaired o r for wh ich you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco T AC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco 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: +61 2 8446 7411 (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)—An existing 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 operations are negatively af fected 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 the network is impaired, while 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.

Chapter 1 Product Overview

Cisco 10720 Internet Router Hardware Features

The Cisco 10720 Internet Router provides two dedicated card slots that are not interchangeable or hot swappable. (See access card.

• The uplink card slot provides the following options:

–

DPT or POS/DPT uplink card: one OC-48c/STM-16c DPT port or two POS optical ports with an aggregate bandwidth of approximately 5 Gbps

–

RPR/SRP uplink card: two OC-48 RPR/SRP (Resilient Packet Ring/Spatial Reuse Protocol) ports that support small form-factor pluggable (SFP) modules, with an aggregate bandwidth of approximately 5 Gbps

–

Console/auxiliary card: console and serial ports only

For more information about the uplink card, refer to the Cisco 10720 Internet Router Uplink Car ds

Installation and Configuration publication.

• The Ethernet access card provides either Fast Ethernet or combined Fast Ethernet and Gigabit

Ethernet connectivity. For more information about the access card, refer to the Cisco Internet

The main processing board contains a central processing engine that consists of two sets of processors that manage the control plane traffic and the data plane traffic.

• The Parallel eXpress Forwarding (PXF) network processors manage the data plane and support IP

forwarding as well as advanced QoS features.

• The multiple processors in the PXF process packets simultaneously at the rate of approximately

2 Mpps.

The Cisco 10720 Internet Router can be deployed directly over fiber, thus allowing service providers to offer IP plus optical access without the need for extensive SONET/Synchronous Digital Hierarchy (SDH) optical transport infrastructure.

The cable connector is a special LC optical connector. When using the card for DPT connections, the left port is the spatial reuse protocol (SRP) side A and the right port is SRP side B. When POS connections are made, the two ports are independent of each other. Each port consists of transmit (TX) and receive (RX). For additional information, see the
