Introduction
For information on new features and the Cisco IOS documentation set supported by Cisco IOS Release 12.1(22)EC1, see the "New and Changed Information" section and the "Related Documentation" section.
Cisco uBR7200 Series Universal Broadband Routers
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 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 cable modems (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.
Cisco IOS Release 12.1(22)EC1 supports the Cisco uBR7246 VXR, Cisco uBR7246, and Cisco uBR7223 universal broadband routers.
Cisco uBR7246 VXR Universal Broadband Router
The Cisco uBR7246VXR offers an industry-proven CMTS and carrier-class router in a scalable platform with a high-performance network processing engine to support data, voice, and video services for medium to large network installations.

Cisco uBR7223 Universal Broadband Router
The Cisco uBR7223 is a cost-effective, scalable interface between subscriber cable modems and the backbone data network, and is designed specifically for small to medium network installations.
The Cisco uBR7223 provides the following major hardware features:
•
Network processing engine
•
I/O controller
•
One network interface port adapter
•
Up to two cable interface line cards
•
One removable power supply (The Cisco uBR7223 does not feature load-sharing and redundant power supply capability like the Cisco uBR7246 VXR and Cisco uBR7246.)
•
Two PCMCIA slots that allow for software upgrades through the use of Flash memory cards
Note
The Cisco uBR7223 router reaches its End of Sale (EOS) point on January 24, 2003. For details see Product Bulletin No. 1955.
Universal Broadband Router Overview
Table 1 provides a quick overview of the major hardware features of the three universal broadband routers.
Note
The Cisco uBR7246VXR router supports the UBR7200-NPE-G1 processor only when running Cisco IOS Release 12.2(11)BC2 or a later Cisco IOS 12.2 BC release. You cannot use the UBR7200-NPE-G1 processor using any release of Cisco IOS 12.1 EC. Cisco IOS Release 12.1 EC does not support the UBR7200-NPE-G1.
Note
Earlier release notes stated that the NPE-175 was also supported on the Cisco uBR7200 series routers. Because the NPE-175 has reached its end of life and was never made orderable on the Cisco uBR7200 series routers, it has been removed from the table.
Early Deployment Releases
These release notes describe the Cisco uBR7200 series universal broadband routers for Cisco IOS Release 12.1(22)EC1. Cisco IOS Release 12.1 EC is an early deployment (ED) release based on Cisco IOS Release 12.1 E, which serves as the train's starting point. Cisco IOS Release 12.1 E, in turn, is based on Cisco IOS Release 12.1 Mainline. Early deployment releases contain fixes to software caveats as well as support for new Cisco hardware and software features. Feature support is cumulative from release to release, unless otherwise noted.
Table 2 lists the features supported by the Cisco uBR7200 series in Cisco IOS Release 12.1(22)EC1.

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 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 using 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 the following cable modems:
–
DOCSIS-based two-way CMs that support basic Internet access, VoIP, or Virtual Private Networks (VPNs).
–
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 STBs with integrated EuroDOCSIS CMs using Cisco MC16E cable interface line cards and Cisco IOS Release 12.1(2)EC1 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 supports the following DOCSIS 1.0 quality of service (QoS) extensions:
–
Multi-Service ID (SID) support, allowing the definition of multiple 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 nonzero 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 (constant bit rate [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 using dynamic MAC messages or the feature set. If the CMs in your network are pure DOCSIS 1.0-based, they 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, MC16E, or MC28C cable interface line card. Only the MC16S, MC16E, and MC28C cable interface line cards support the external clock reference from the clock card to distribute that signal to CMs or STBs attached to the specific network segments. A chassis configured with an MC16S or MC16E cable interface line card must be running Cisco IOS Release 12.1(2)EC1 or higher. A chassis configured with an MC28C cable interface line card must be running Cisco IOS Release 12.1(3a)EC1 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 the clock reference feature set automatically.
