Introduction

For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.1 XQ, see the "New and Changed Information" section and the "Related Documentation" section.

The Cisco uBR7200 Series Universal Broadband Routers—the Cisco uBR7223, the Cisco uBR7246, and the Cisco uBR7246 VXR—are based on the Data Over Cable Service Interface Specification (DOCSIS) standards. Each is designed to be installed at a service provider's headend facility.

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. These routers function as the cable modem termination system (CMTS) for subscriber-end devices such as Cisco uBR904 and Cisco uBR924 Cable Access Routers, and other DOCSIS-compliant cable modems (CMs) and set top boxes (STBs).

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 is via 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 introduction of the WT2700 Wireless Technology Suite also allows the Cisco uBR7246 VXR, Cisco uBR7246, and Cisco uBR7223 Universal Broadband Routers to become either a two-way high-speed point-to-point wireless system that provides fixed, dedicated wireless links from one headend site to another, or a two-way high-speed multipoint wireless system that provides fixed, dedicated wireless links from one headend site to multiple subscriber units.

The point-to-point link delivers full-duplex data in the unlicensed U-NII band (5.725 to 5.825 GHz). The multipoint link delivers full-duplex data in the licensed Multichannel Multipoint Distribution Service (MMDS) band (2.150 to 2.162 GHz and 2.500 to 2.690 GHz). The WT2700 Wireless Technology Suite includes the wireless modem card, which is installed in the Cisco uBR7200 series chassis, and the Cisco WT2772 wireless transverter, duplexer, and power feed panel, which are external components.

The Cisco uBR7200 series routers support Internet Protocol (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.

Cisco IOS Release 12.1(3) XQ4 supports cable and fixed wireless system configurations using the Cisco uBR7246 VXR, Cisco uBR7246, and Cisco uBR7223.

---

Note All Cisco IOS Release 12.1(3) XQ4 images require 64 MB of DRAM. All images support all of the hardware listed in the "Supported Hardware" section, unless otherwise indicated.

---

System Interoperability

This section clarifies the operation of certain features in the Cisco uBR7200 Series Universal Broadband Routers:

•DOCSIS 1.0 Baseline Privacy

DOCSIS Baseline Privacy Interface (BPI) gives subscribers data privacy across the radio frequency (RF) network, encrypting traffic flows between the CMTS and CM. BPI ensures that a CM, uniquely identified by its Media Access Control (MAC) address, can obtain keying material for services only it is authorized to access.

To enable BPI, choose software at both the CMTS and CM that support the mode of operation. For the Cisco uBR7200 series software, choose an image with "k1" in its file name or BPI in the feature set description.

The CM must also support BPI. CMs must have factory-installed RSA private/public key pairs to support internal algorithms to generate key pairs prior to first BPI establishment. BPI must be enabled via the DOCSIS configuration file.

---

Note RSA stands for Rivest, Shamir, and Adelman, inventors of a public-key cryptographic system.

---

•CM Interoperability

The Cisco uBR7200 series interoperates with:

–DOCSIS-based two-way CMs that support basic Internet access, VoIP, or VPN support.

–Telco-return CMs—To support telco return, use a Cisco uBR7200 series software image that contains "t" in its file name. The telco return CM must be DOCSIS-based or compliant, and must be configured to support telco return.

---

Note Some third-party telco-return CMs cannot receive traffic over the same downstream channel as CMs operating on a two-way data system. In these instances, segment your cable plant to allow more than one downstream channel.

---

–EuroDOCSIS CMs or set top boxes (STBs) with integrated EuroDOCSIS CMs using Cisco MC16E Cable Modem Cards and Cisco IOS Release 12.1(1a)T1 or higher. EuroDOCSIS operation support includes 8 MHz Phase Alternating Line (PAL) or Systeme Electronique Couleur Avec Memoire (SECAM) channel plans.

•DOCSIS 1.0 Extensions

The Cisco uBR7200 series support DOCSIS 1.0 QoS extensions that include:

–Multi-SID support, allowing the definition of multiple Service IDs (SIDs) on the upstream: Voice traffic can be designated on a higher QoS committed information rate (CIR) secondary SID, while data traffic can be forwarded on a best effort basis on a primary SID. Secondary SIDs are higher QoS CIR-type classes that have a non-zero minimum reserved rate (CIR-type service). These SIDs receive preferential treatment at the CMTS for grants over any tiered best effort type data SID of that upstream. Reliable operation with voice requires multiple SIDs—at least two per CM to separate voice from data. In DOCSIS 1.0, SIDs are set up statically. When supporting DOCSIS 1.0 extensions, SIDs can be set up statically or dynamically. Both the CMTS and CM must support this capability.

–CM-initiated dynamic MAC messages: Dynamic Service Addition (DSA) and Dynamic Service Deletion (DSD). These messages allow dynamic SIDs to be created and deleted at run-time on a per VoIP call basis.

–Unsolicited grant service (CBR-scheduling) on the upstream: This helps provide a higher quality channel for upstream VoIP packets from an Integrated Telephony Cable Modem (ITCM) such as the Cisco uBR924 Cable Access Router.

–Ability to provide separate downstream rates for any given ITCM, based on the IP-precedence value in the packet: This helps separate voice signaling and data traffic that goes to the same ITCM to address rate shaping purposes.

–Concatenation—To increase the per-CM upstream throughput in certain releases of software, Cisco uBR7200 series software supports a concatenated burst of multiple MAC frames from a CM that supports concatenation.

---

Note All DOCSIS 1.0 extensions are activated only when a CM or Cisco uBR924 that supports these extensions solicits services via dynamic MAC messages or the feature set. If the CMs in your network are pure DOCSIS 1.0-based, they will receive regular DOCSIS 1.0 treatment from the CMTS.

---

•Clock Synchronization

The Cisco uBR7200 series support clock hardware and software to enable high-quality delivery of IP telephony services through synchronized data transmissions. To support the clock feature set, a Cisco uBR7246 VXR chassis must be used. The Cisco uBR7246 VXR must contain a clock card and an MC16S or MC16E Cable Modem Card. Only the MC16S and the MC16E Cable Modem Cards support the external clock reference from the clock card to distribute that signal to CMs or set top boxes (STBs) attached to the specific network segments. The chassis must be running Cisco IOS Release 12.1(1a)T1 or higher.

Each cable modem must also support VoIP applications and the clock reference feature set to enable synchronized timing. The Cisco uBR924 Cable Access Router, running Cisco IOS Release 12.0(7)T or later, supports clock automatically.

IOS (tm) 12.1 XQ Software (ubr7200-is-mz), Version 12.1(3) XQ4, RELEASE SOFTWARE

Upgrading to a New Software Release

For general information about upgrading to a new software release, see Cisco IOS Upgrade Ordering Instructions located at http://www.cisco.com/warp/public/cc/cisco/mkt/ios/prodlit/957_pp.htm.

The multipoint wireless modem card (uBR-MCW-MDA) for the Cisco uBR7200 Series Universal Broadband Router requires a microcode bundle (RHE) to allow it to operate.

Microcode software images ship in Flash memory along with the system software image. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface linecards.

It is possible to use a later version of microcode software than the one shipped with the Cisco IOS software from the factory. The microcode software in Flash memory is mapped to the linecards.

The microcode bundle for the multipoint wireless modem card is downloadable (with a Cisco.com login) at http://www.cisco.com/cgi-bin/tablebuild.pl/rhe.

---

Note Unless you fully understand how Cisco IOS software uses microcode software, it is important to keep the factory configuration.

Feature Set Tables

The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.

Cisco IOS Release 12.1(3) XQ4 supports the same feature sets as Cisco IOS Release 12.1(3)T, but adds new features supported by the Cisco uBR7200 series.

Table 7 lists the features and feature sets supported by the Cisco uBR7200 series in Cisco IOS Release 12.1(3) XQ4 and uses the following conventions:

•Yes—The feature is supported in the software image.

•No—The feature is not supported in the software image.

•In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, (3) means a feature was introduced in Release 12.1(3) XQ4. If a cell in this column is empty, the feature was inherited from Release 12.1(3)T. For information about features inherited from Release 12.1(3)T, refer to the release notes for Release 12.1(3)T.
