Overview of Cisco Universal Broadband Routers

The Cisco uBR7100 series universal broadband routers—the Cisco uBR7111, Cisco uBR7111E, Cisco uBR7114, and Cisco uBR7114E—are based on the Data-over-Cable Service Interface Specification (DOCSIS) standards and designed to be installed at small cable operators and multiple dwelling unit (MDU) operators to enable them to offer services such as e-mail, high-speed Internet access, voice, and digital video over a bidirectional cable television and IP backbone network. The universal broadband routers function as the cable modem termination system (CMTS) for subscriber-end devices such as Cisco uBR905, Cisco uBR924, and Cisco uBR925 cable access routers, and other DOCSIS-compliant cable modems (CMs) and set-top boxes (STBs).

Both the Cisco uBR7100 series and 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. The Cisco uBR7100 series routers support IP routing with a wide variety of protocols and WAN interfaces selections.

Cisco IOS Release 12.3(23)BC4 supports the Cisco uBR7111, Cisco uBR7111E, Cisco uBR7114, and Cisco uBR7114E universal broadband routers.

Cisco uBR7100 Series Universal Broadband Routers

The Cisco uBR7100 series routers provide a fixed set of WAN and LAN interfaces with a combination of fixed and modular interfaces, allowing both flexibility and simplicity in configuration. Each Cisco uBR7100 series router includes one modular single-width port adapter, one integrated cable interface with an internal upconverter, and two integrated Fast Ethernet ports. The cable interface is based on the Cisco uBR-MC14C cable interface line card and is not field-replaceable.

The Cisco uBR7100 series routers support IP routing through the following optional WAN and LAN port adapters: Ethernet, Fast Ethernet, serial, High-Speed Serial Interface (HSSI), Packet over SONET (POS) OC-3c, and Asynchronous Transfer Mode (ATM) media. For more information, see Table 4.

Depending on the model, the Cisco uBR7100 series routers support the following two standards:

•Data Over Cable Service Interface Specifications (DOCSIS), which supports the 6 MHz North American channel plans using the ITU J.83 Annex B RF standard. The downstream uses a 6 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports the 5 to 42 MHz frequency range.

•European Data Over Cable Service Interface Specifications (EuroDOCSIS), which supports the 8 MHz Phase Alternating Line (PAL) and Systeme Electronique Couleur Avec Memoire (SECAM) channel plans using the ITU J.112 Annex A RF standard. The downstream uses an 8 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports multiple channel widths in the 5 to 65 MHz frequency range.

The Cisco uBR7100 series offers the following models:

•The Cisco uBR7111 and Cisco uBR7111E universal broadband routers provide a cable interface with one downstream port and one upstream port. The downstream port can be output either as an RF signal through the integrated upconverter or as an IF signal for processing by an external upconverter. The Cisco uBR7111 router supports DOCSIS cable plants, and the Cisco uBR7111E supports EuroDOCSIS cable plants.

•The Cisco uBR7114 and Cisco uBR7114E universal broadband routers provide a cable interface with one downstream port and four upstream ports. The downstream port can be output either as an RF signal through the integrated upconverter or as an IF signal for processing by an external upconverter. The Cisco uBR7114 router supports DOCSIS cable plants, and the Cisco uBR7114E supports EuroDOCSIS cable plants.

Cisco uBR7111 and Cisco uBR7111E Universal Broadband Routers

The Cisco uBR7111 and Cisco uBR7111E provide the following major hardware features:

•Integrated network processing engine

•1 upstream cable modem interface

•1 downstream cable modem interface

•2 Fast Ethernet ports

•1 port adapter slot

•1 service adapter slot

•1 AC power supply

DOCSIS System Interoperability on the Cisco uBR7100 Series CMTS

This section describes the operation of primary interoperability features in the Cisco uBR7100 series router. For additional DOCSIS information, refer to the following document on Cisco.com:

•DOCSIS 1.1 for the Cisco CMTS

http://www.cisco.com/en/US/docs/cable/cmts/feature/guide/ufg_docs.html.

DOCSIS 1.0 Baseline Privacy

DOCSIS baseline privacy interface (BPI) gives subscribers data privacy across the RF network, encrypting traffic flows between the cable modem termination system (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 uBR7100 series router supports DOCSIS-based two-way interoperability for cable modems that support basic Internet access, 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.

Note Cisco IOS Release 12.3(21a)BC3 does not support telco-return cable modems or STBs.

Configuring the CMTS Cable Interface When in Routing Mode

If you have configured a Cisco cable modem (CM) for routing mode and are also using the cable-modem dhcp-proxy nat command on the cable modem, you must configure the corresponding cable interface on the Cisco uBR7100 series router with the cable dhcp-giaddr policy command. Otherwise, the cable interface could flap and the CM could go offline unpredictably.

DOCSIS 1.0 and 1.0+ Extensions

Earlier releases of Cisco IOS software for the Cisco uBR7100 series 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 ID (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 timeslots that are available between the timeslots used for the real-time traffic.

•Concatenation allows a cable modem to send multiple MAC frames in the same timeslot, 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 uBR7100 series 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.

Feature Support

Cisco IOS software is packaged in feature sets that consist of software images that support specific platforms. The feature sets available for a specific platform depend on which Cisco IOS software images are included in a release. Each feature set contains a specific set of Cisco IOS features.

Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to U.S. government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of U.S. government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

The feature set tables have been removed from the Cisco IOS Release 12.3 release notes to improve the usability of the release notes documentation. The feature-to-image mapping that was provided by the feature set tables is available through Cisco Feature Navigator.

Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image).
