Table 3 Cisco uBR10012 Universal Broadband Router Supported Hardware 

Cable Interface Line Cards	Up to eight of the following broadband processing engines and cable interface line cards can be housed in a chassis in any combination: •Cisco uBR10-MC5X20S/U/H Cable Interface Line Card •Cisco uBR10-LCP2-MC16C/MC16E/MC16S Cable Interface Line Card •Cisco uBR10-LCP2-MC28C Cable Interface Line Card Note The Cisco uBR10-LCP2-MC16C/MC16E/MC16S and the Cisco uBR10-LCP2-MC28C are end of sale as of June 2005. For additional information, refer to END-OF-LIFE NOTICE, NO. 2600: http://www.cisco.com/en/US/products/hw/cable/ps2209/prod_eol_notice0900aecd80183921.html Note The Cisco uBR7200 Series MC28U BPE does not support the Cisco uBR10012 router, though the Cisco MC28U BPE physically fits into the Cisco uBR10012 router chassis.
Cisco Half-Height Gigabit Ethernet Line Card	The Gigabit Ethernet (GigE) line card is a half-height, single-port, full-bandwidth Gigabit Ethernet line card providing multiple GigE links to the IP backbone. The Cisco half-height GigE line card also supports DOCSIS wideband capability through the Cisco uBR10000 universal broadband router.
Network Uplink Line Cards	Up to four line cards with any combination of the following WAN choices: •Cisco uBR10-SRP-OC12SML DPT WAN Line Card for the Cisco uBR10012 Router •Cisco uBR10012 OC-48 DPT/POS interface module •Cisco uBR10-1GE Gigabit Ethernet (GigE) uplink line card •Cisco uBR10-1OC12/P-SMI OC-12 POS uplink line card •Cisco uBR10-SRP-OC12SML Dynamic Packet Transport (DPT) WAN card
Timing, Communication and Control Plus (TCC+) Card	The TCC+ card can connect to an external reference Stratum 3 clock source that is traceable to a Stratum 1 source. Two such sources can be connected for redundancy. The TCC+ card also monitors the cable line cards and power supply use, as well as control the LCD display screen on the chassis. Two cards can be installed for redundancy.
Performance Routing Engine 2 (PRE2)	The new Cisco uBR10012 Series PRE2 effectively doubles the bandwidth available to each slot on the router as supported by cable interface line cards or Cisco Broadband Processing Engines. The PRE2 module introduces support for full-duplex Gigabit Ethernet ports, and increases the supported connections to 1.6 Gbps in full duplex (each direction per half-slot). Full-slot modules can now have up to 3.2 Gbps to and from the PRE2 module. This is twice the connection rate of the Cisco uBR10012 PRE1 route processor module.
Performance Routing Engine (PRE or PRE1)	One PRE or PRE1 module performs layer 2 and layer 3 packet processing, as well as routing and system management functions. Two PRE or PRE1 modules can be installed for redundancy. Note The PRE1 module is functionally identical to the PRE module except that it adds support for the Error Checking and Correction (ECC) feature, which can automatically correct single-bit memory errors. Note The Cisco uBR10012 PRE1 module supports an Ethernet port to a LAN for a 10BASE-T or 100BASE-T connection for network management. The PRE1 module supports connections of 800 Mbps in full duplex (each direction) per half-slot.
AC-Input Power Entry Module (PEM)	The Cisco uBR10012 router ships with two AC power entry modules (AC PEMs) that provide a redundant power supply to the system. One AC PEM can provide sufficient power for a fully configured chassis, so that if one AC PEM fails, the other automatically begins providing power for the entire router, without impacting system operations. The AC PEMs use standard 200-240 VAC (50/60 Hz) input power obtained through power receptacles on the front panel of each PEM. The two AC PEMs convert the AC power to provide filtered, redundant, and load shared DC power to the Cisco uBR10012 chassis. Caution The Cisco uBR10012 router does not support mixing AC and DC PEMs. Both PEMs must be either AC PEMs or DC PEMs.
DC-input Power Entry Module (PEM)	The Cisco uBR10012 router may ship with two DC PEMs to provide power to the chassis. The use of two PEMs provide power balancing and redundancy, as well as the ability to hot-swap a single power supply when needed. Caution The Cisco uBR10012 router does not support mixing AC and DC PEMs. Both PEMs must be either AC PEMs or DC PEMs.
Fan Assembly Module	The fan assembly module contains four fans that are capable of cooling the chassis even with the failure of a single fan. The fan assembly is dual-speed, providing additional cooling when the chassis temperature exceeds the nominal operating range.

Additional High Availability and Security features as described elsewhere in this document.

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 cable modem. BPI ensures that a cable modem, 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 cable modem that support this mode of operation. Select a Cisco IOS image that supports BPI. BPI must be enabled using the DOCSIS configuration file.

The cable modem must also support BPI. Cable modems must have factory-installed RSA private/public key pairs to support internal algorithms to generate key pairs prior to first BPI establishment.

---

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

---

Cable Modem Interoperability

•The Cisco uBR10012 router supports DOCSIS 1.1-based, two-way interoperability for cable modems that support basic Internet access, Voice over IP (VoIP), or Virtual Private Networks (VPNs).

•EuroDOCSIS cable modems or set-top boxes (STBs) with integrated EuroDOCSIS CMs using Cisco uBR-MC16E cable interface line cards and Cisco IOS Release 12.2(4)BC1 or higher. EuroDOCSIS operation support includes 8-MHz Phase Alternating Line (PAL) or Systeme Electronique Couleur Avec Memoire (SECAM) channel plans.

DOCSIS 1.0 and 1.0+ Extensions

Earlier releases of Cisco IOS software for the uBR10012 router provide support for the original DOCSIS 1.0 standard, featuring basic best-effort data traffic and Internet access over the coaxial cable network. The DOCSIS 1.0+ extensions provides Quality of Service (QoS) enhancements for real-time traffic, such as voice calls, in anticipation of full DOCSIS 1.1 support.

---

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

---

DOCSIS 1.1 Extensions

The DOCSIS 1.1 specification provides the following functional enhancements over DOCSIS 1.0 coaxial cable networks:

•Enhanced Quality of Service (QoS) gives priority for real-time traffic such as voice and video.

–The DOCSIS 1.0 QoS model (a Service IDs (SID) associated with a QoS profile) has been replaced with a service flow model (SFID). This allows greater flexibility in assigning QoS parameters to different types of traffic and in responding to changing bandwidth conditions.

–Multiple service flows per cable modem supported in either direction due to packet classifiers.

–Support for multiple service flows per cable modem allows a single cable modem to support a combination of data, voice, and video traffic.

–Greater granularity is available in QoS per cable modem (in either direction), using unidirectional service flows.

–Dynamic MAC messages are supported to create, modify, and tear down QoS service flows dynamically when requested by a DOCSIS 1.1 cable modem.

•Several QoS models are supported for the upstream.

–Best effort-Data traffic is sent on a non-guaranteed best-effort basis.

–Committed Information Rate (CIR) supports the guaranteed minimum bandwidth for data traffic.

–Unsolicited Grants (UGS) support constant bit rate (CBR) traffic, such as voice, that is characterized by fixed size packets at fixed intervals.

–Real Time Polling (rtPS) supports Real Time service flows, such as video, that produce unicast, variable size packets at fixed intervals.

–Unsolicited Grants with Activity Detection (USG-AD) support the combination of UGS and RTPS, to accommodate real time traffic that might have periods of inactivity (such as voice using silence suppression). The service flow uses UGS fixed grants while active, but switches to RTPS polling during periods of inactivity to avoid wasting unused bandwidth.

•Enhanced time-slot scheduling mechanisms support guaranteed delay/jitter sensitive traffic on the shared multiple access upstream link.

•Payload header suppression (PHS) conserves link-layer bandwidth by suppressing unnecessary packet headers on both upstream and downstream traffic flows.

•Layer 2 fragmentation on the upstream prevents large data packets from affecting real-time traffic, such as voice and video. Large data packets are fragmented and then transmitted in the time slots that are available between the time slots used for the real-time traffic.

•Concatenation allows a cable modem to send multiple MAC frames in the same time slot, as opposed to making an individual grant request for each frame. This avoids wasting upstream bandwidth when sending a number of very small packets, such as TCP acknowledgement packets.

•DOCSIS 1.1 cable modems can coexist with DOCSIS 1.0 and 1.0+ cable modems in the same network—the Cisco uBR10012 router provides the levels of service that are appropriate for each cable modem.

DOCSIS 1.1 Quality of Service

The DOCSIS 1.1 QoS framework is based on the following objects:

•Service class: A collection of settings maintained by the CMTS that provide a specific QoS service tier to a cable modem that has been assigned a service flow within a particular service class.

•Service flow: a unidirectional sequence of packets receiving a service class on the DOCSIS link.

•Packet classifier: A set of packet header fields used to classify packets onto a service flow to which the classifier belongs.

•PHS rule: A set of packet header fields that are suppressed by the sending entity before transmitting on the link, and are restored by receiving entity after receiving a header-suppressed frame transmission. Payload header suppression increases the bandwidth efficiency by removing repeated packet headers before transmission.

In DOCSIS 1.1, the basic unit of QoS is the service flow, which is a unidirectional sequence of packets transported across the RF interface between the cable modem and CMTS. A service flow is characterized by a set of QoS parameters such as latency, jitter, and throughput assurances.

Every cable modem establishes a primary service flow in both the upstream and downstream directions. The primary flows maintain connectivity between the cable modem and CMTS at all times.

In addition, a DOCSIS 1.1 cable modem can establish multiple secondary service flows. The secondary service flows can either be permanently created (they persist until the cable modem is reset or powered off) or they can be created dynamically to meet the needs of the on demand traffic being transmitted.

Each service flow has a set of QoS attributes associated with it. These QoS attributes define a particular class of service and determine characteristics such as the maximum bandwidth for the service flow and the priority of its traffic. The class of service attributes can be inherited from a preconfigured CMTS local service class (class-based flows), or they can be individually specified at the time of the creation of the service flow.

Each service flow has multiple packet classifiers associated with it, which determine the type of application traffic allowed to be sent on that service flow. Each service flow can also have a Payload header suppression (PHS) rule associated with it to determine which portion of the packet header will be suppressed when packets are transmitted on the flow.
