Document Objectives

This guide describes configuring, maintaining, and troubleshooting the Cisco uBR7200 series universal broadband routers: the Cisco uBR7223, Cisco uBR7246, and Cisco

uBR7246 VXR. Cisco’s Cable Modem Termination System (CMTS) solutions allow cable companies, Internet service providers (ISPs), and others to allocate channel capacity for Internet access, Virtual Private Network (VPN), and Voice over IP (VoIP) services using a broadband radio frequency (RF) cable plant.

The Cisco uBR7200 series universal broadband routers sustain downstream and upstream traffic to and from two-way Data Over Cable Service Interface Specification (DOCSIS)-based cable modems (CMs) that support 6 MHz National Television Systems Committee (NTSC) operations. For NTSC cable plants not upgraded for full two-way operations, the routers also support DOCSIS-compliant telco-return CMs. For international cable companies using 8 MHz channel widths, the Cisco

uBR7200 series equipment supports Phase Alternating Line (PAL) and Systeme Electronique Couleur Avec Memoire (SECAM) channel plans to operate with EuroDOCSIS-based CMs and set

top box (STB) units with integrated

EuroDOCSIS modems.

OL-2239-04

Preface

Audience

This guide is intended for system administrators and support engineers who configure and maintain the Cisco

uBR7200 series. Many different delivery models exist for Cisco uBR7200 series equipment:

• In smaller networks, a single service provider manages all equipment and infrastructure.

• In larger networks, multiple service operators (MSOs) and ISPs share responsibility for provisioning

and managing the cable plant and IP network.

The MSO and ISP divide responsibilities according to the service model. In some cases, the MSO maintains and operates the cable plant and attached CMs and STBs, whereas the ISP owns, operates, and maintains the regional network and IP infrastructure beyond the cable distribution hub. In other cases, the CMTS and RF customer premises equipment (CPE) are viewed as part of the networking infrastructure, and the ISP maintains control for provisioning and managing DOCSIS functionality.

Note This guide considers the MSO and ISP as a single service principle with responsibility to provision and

manage DOCSIS-based cable modems and set-top boxes (STBs). This guide assumes that administrators are familiar with Cisco

uBR7200 series hardware, DOCSIS or EuroDOCSIS requirements, and

networking.

An upgrade is an order placed for a Cisco IOS feature set that contains more functionality than the feature set that you are replacing. An upgrade is not an “update.” An update consists of installing a more recent version of the same feature set.

• Exception—If a feature set has been made obsolete, the next closest feature set on a more recent

release is considered an update.

For general information about upgrading to a new software release, refer to the Cisco IOS Upgrade

12.3 BC Release Train Images and Requirements

The Cisco 12.3 BC release train is the latest Cisco IOS release train to support the Cisco uBR7200 Series, and emphasizes additional features and performance specifically for the Cisco uBR7246VXR universal broadband router.

Table 1-2 displays the memory recommendations of the Cisco IOS feature sets for the

Cisco uBR7200 series universal broadband routers for Cisco IOS Release 12.3(9a)BC. Cisco

uBR7200 series routers are only available with a 48 MB or 128 MB of Flash disk memory on the

I/O Controller cards. The UBR7200-NPE-G1 uses compact Flash disk only.

Note Flash disks, an alternative to linear Flash memory, are Flash memory-based devices that can be used as

file storage media in the PCMCIA card slots of the I/O Controllers. Each I/O Controller has two PCMCIA slots and can be configured with up to 256 MB of Flash disk memory.

The image subset legend for Tab l e 1-2 is as follows:

• i = IP routing, MPLS-VPN support, and non-cable interface bridging, including Network Address

Translation (NAT)

• k8 = DOCSIS Baseline Privacy

• p = IP routing with Intermediate System-to-Intermediate System (IS-IS) and Border Gateway

Protocol (BGP); MPLS-VPN support; no bridging and no NAT

12.2 CX Images and Requirements

The 12.2 CX releases are based on Cisco IOS Release 12.2(15)BC1, which is a child of Cisco IOS Release

12.2(15)T. The 12.2 BC train is an interim release train that provides DOCSIS 1.1 two-way

support, along with fixes for software caveats and support for selected new features.

The latest image in the 12.2 CX release train, Cisco IOS Release 12.2(15)CX1, provides two different boot images for the Cisco uBR7200 series routers:

• ubr7200-kboot-mz.122-15.CX.bin

The "kboot" version of the boot image is a new version of the boot image software that can run only on the Cisco uBR7200-NPE-G1 processor and the UBR7200-I/O-2FE/E I/O controller, because it is too large to load on the other I/O controllers. This image contains support for almost all supported port adapters, allowing the Cisco uBR7246VXR router to boot over almost any type of WAN interface.

• ubr7200-boot-mz.122-15.CX.bin

The "boot" version of the boot image is small enough to be loaded on I/O controllers with 4MB of Flash memory, but it supports only Ethernet, FastEthernet, Gigabit Ethernet, OC POS, and a limited number of ATM port adapters. If you are using a serial port adapter or most ATM port adapters, you will not be able to boot over the WAN interface.

This difference in boot images affects only the ability of the Cisco uBR7246VXR router to boot over the WAN interface. When the router has successfully loaded the Cisco IOS software, it has connectivity over all of the port adapters that this particular version of Cisco IOS software supports.

Table 1-3 displays the memory recommendations of the Cisco IOS feature sets for the Cisco uBR7200

series universal broadband routers for Cisco IOS Release 12.2(15)CX1. Cisco uBR7200 series routers are only available with a 48 MB or 128 MB of Flash disk memory on the I/O Controller cards. The UBR7200-NPE-G1 uses only compact Flash disk.

Chapter 1 Overview of Cisco uBR7200 Series Software

Cisco uBR7200 Series Chassis Overview

The Cisco uBR7200 series universal broadband routers allow high-speed data services to be packaged similar to cable TV service or video fare. Cisco uBR7200 Series equipment supports data and digitized voice connectivity between Internet Protocol (IP) hosts and connected subscribers using a bidirectional cable TV and IP backbone.

Note For 6 MHz National Television Systems Committee (NTSC) cable plants not fully upgraded to two-way

transmission, the equipment works with dial-up access products to support upstream traffic from Data-over-Cable Service Interface Specification (DOCSIS)-based telco-return cable

interfaces.

For international cable plants that use 8-MHz Phase Alternating Line (PAL) or Systeme Electronique Couleur Avec Memoire (SECAM) channel plans, Cisco uBR7200 Series equipment supports bidirectional transfer of traffic between the Cable

Modem Termination System (CMTS) and

EuroDOCSIS-based CMs or set top box (STB) units with integrated EuroDOCSIS modems.

Cable companies and Internet service providers (ISPs) can allocate radio frequency (RF) channel capacity for Internet access, Virtual Private Network (VPN), or Voice over IP (VoIP) services using a hybrid fiber/coax (HFC) or all-coax cable

plant. Cisco currently provides three router-based DOCSIS

CMTS solutions that offer a wider feature set and better manageability than bridge-based systems.

• Cisco uBR7246 VXR Universal Broadband Router—Supports higher density and broad media

configurations; the chassis contains up to two single-width IP backbone interfaces, up to four cable TV RF interfaces, up to two power supplies, an optional clock interface that enables the router to synchronize to an external timing reference, a faster processor, and higher bus bandwidth.

• Cisco uBR7246 Universal Broadband Router—Supports large cable installations; the chassis

contains up to two single-width IP backbone interfaces, up to four cable TV RF interfaces, and up to two power supplies.

• Cisco uBR7223 Universal Broadband Router—Supports small-to-medium cable installations; the

chassis contains one single-width IP backbone interface and up to two cable TV RF interfaces.

Note This guide focuses on Cisco uBR7200 Series software. For detailed descriptions of Cisco uBR7200

Series chassis and components, refer to the

Cisco uBR7200 Series Hardware Installation Guide and

appropriate field replaceable unit (FRU) documents on Cisco.com.

Cisco cable interface line cards serve as the RF cable TV interfaces, supporting downstream and upstream signal combining and splitting arrangements. The cards currently require external upconverters to connect to the cable system. Cisco port adapters connect to the IP backbone and external networks. Your cable plant, combined with your planned and installed subscriber base, service offering, and external network connections, determine the Cisco uBR7200 Series chassis, cable interface line cards, port adapters, and other components you use.

Data is modulated or demodulated using either of the following two methods:

• Downstream 6 MHz channels in the 54-to-860 MHz range with upstream ranges of 5 to 42 MHz.

Cisco MC11 FPGA, MC11C, MC12C, MC14C, MC16B, MC16C, and MC16S cable interface line cards support NTSC channel operation, using standard (STD), Harmonic Related Carrier (HRC), or Incremental Related Carrier (IRC) frequency plans conforming to EIA-S542.

NTSC uses a 6 MHz-wide modulated signal with an interlaced format of 25 frames per second and 525 lines per frame. NTSC is compatible with CCIR Standard M.

PAL, used in West Germany,

England, Holland, Australia, and several other countries.

OL-2239-05

Chapter 1 Overview of Cisco uBR7200 Series Software

Cisco uBR7200 Series Chassis Overview

Note Cisco 6 MHz products can be used in 8 MHz cable plants. The products, however, operate at a

maximum downstream bandwidth of 27 Mbps, ignoring 2 MHz of available channel width, and limiting upstream channel choices to the range below 42 MHz.

• Downstream 8 MHz channels in the 85-to-860 MHz range with an upstream range of 5 to 65 MHz.

The Cisco MC16E cable interface line card supports PAL and SECAM channel plans using an 8

MHz modulated signal.

PAL uses a 625-line scan picture delivered at 25 frames per second where the color carrier phase definition changes in alternate scan lines. SECAM uses an 819 line scan picture that provides better resolution than PAL's 625-line and NTSC's 525-line.

The MC16E uses the EuroDOCSIS J.112 (Annex A) standard, CableLabs ECR RFI-R-98036, which is similar to the Digital Audio Video Council/Digital Video Broadcast (DAVIC/DVB) ITU

J.83

Annex

A physical layer. Cable companies can support data, voice, and video services with

DOCSIS-based CMs or set top boxes (STBs) that contain integrated EuroDOCSIS modems.

Caution The MC16E supports only Annex A operation and should not be used in production cable plants that

support a 6 MHz channel plan.

Note The difference between DOCSIS and EuroDOCSIS is at the physical layer. EuroDOCSIS support

requires the Cisco MC16E cable interface line card, appropriate upconverters that support an 8

MHz

PAL or SECAM channel plan, appropriate diplex filters, and EuroDOCSIS-based CMs or STBs.

The DOCSIS Radio Frequency (RF) specification defines the RF communication paths between the CMTS and CMs (or CMs in STBs). The DOCSIS RF specification defines the physical, link, and network layer aspects of the communication interfaces. It includes specifications for power level, frequency, modulation, coding, multiplexing, and contention control. Cisco offers products that support all DOCSIS error correction encoding and modulation types and formats, and that support DOCSIS Annex B or EuroDOCSIS Annex A operations.

Cisco uBR7200 Series Universal Broadband Routers

The Cisco uBR7200 series universal broadband routers are based on the Data-over-Cable Service Interface Specification (DOCSIS) standards. Each is designed to be installed at a cable operator's headend facility or distribution hub and to function as the cable modem termination system (CMTS) for subscriber-end devices such as the Cisco uBR905 and Cisco uBR925 cable access routers, and other DOCSIS-compliant CMs and set-top boxes (STBs).

Cisco uBR7200 series universal broadband routers allow two-way transmission of digital data and Voice over IP (VoIP) traffic over a hybrid fiber-coaxial (HFC) network. For cable plants not fully upgraded to support two-way cable transmission, the routers support DOCSIS-compliant telco return, where the cable modem's return path to the CMTS uses a dial-up telephone line connection instead of an upstream channel over the coaxial cable. The telco-return delivery mechanism enables cable operators to accelerate deployment of high-speed data services before the cable systems are upgraded to two-way plants.

The Cisco uBR7200 series routers support IP routing with a wide variety of protocols and combinations of Ethernet, Fast Ethernet, Gigabit Ethernet, serial, High-Speed Serial Interface (HSSI), Packet over SONET (POS) OC-3 and OC-12c, and Asynchronous Transfer Mode (ATM) media.
