Chapter 2 Cisco Cable Wideband Components Wideband CMTS Redundancy and Resiliency Wideband CMTS Redundancy and Resiliency The uBR10012 wideband CMTS and related hardware and software provide redundancy and resiliency to the Cisco Cable Wideband Solution. Reliable, fault-tolerant components and resilient network technologies automatically identify and overcome failures.
Chapter 2 Cisco Cable Wideband Components Wideband CMTS Redundancy and Resiliency PRE2 Redundancy and Resiliency The Route Processor Redundancy Plus (RPR+) feature and DOCSIS Stateful Switchover (DSSO) in the Cisco IOS software provide the Cisco uBR10012 router’s PRE2 route processors with fast route processor failover without DOCSIS line card reboot.
Chapter 2 Cisco Cable Wideband Components Wideband CMTS Redundancy and Resiliency N+1 Redundancy can help limit Customer Premises Equipment (CPE) downtime by enabling robust automatic switchover and recovery in the event that there is a localized system failure. N+1 Redundancy adds synchronization between Hot Standby Connection-to-Connection Protocol (HCCP) Working interface configurations and those inherited upon switchover to HCCP Protect interfaces.

C H A P T E R 3 Cisco Cable Wideband Architecture This chapter explains the architecture used for the Cisco Cable Wideband Solution, Release 1.0. It explains the following topics: • Wideband Channel Bonding, page 3-1 • Modular CMTS, page 3-4 • Gigabit Ethernet Switch Functionality, page 3-8 • Edge QAM Device Functionality, page 3-8 • Wideband Cable Modem Functionality, page 3-9 The DOCSIS 3.0 Downstream Channel Bonding feature is backward compatible with DOCSIS 1.X/2.0 services and networks.
Chapter 3 Cisco Cable Wideband Architecture Wideband Channel Bonding The DOCSIS 3.0 Downstream Channel Bonding feature is overlaid on top of and is transparent to a DOCSIS 2.0 system. In the Cisco Cable Wideband Solution, Release 1.0, these channels are used for wideband operations: • For the wideband downstream channel, the Wideband SPA uses its Gigabit Ethernet port to send data traffic to the EQAM device.
Chapter 3 Cisco Cable Wideband Architecture Wideband Channel Bonding The Cisco Wideband SPA on the uBR10012 router provides the logical RF channels for the DOCSIS 3.0 Downstream Channel Bonding feature. The service provider uses a customized set of Cisco IOS commands to configure the Wideband SPA for each wideband channel and its associated DOCSIS 2.0 downstream and upstream channels.
Chapter 3 Cisco Cable Wideband Architecture Modular CMTS Figure 3-2 Wideband Channels and Primary Downstream Channels on a Fiber Node WB1 PDC2 NB2 190002 PDC1 NB1 WB2 A WCM on the fiber node can come online on WB1/PDC1, on WB1/PDC2, or on WB2/PDC1. On the CMTS, WB1, WB2, PDC1, and PDC2 all are members of the same virtual interface bundle. For information on configuring virtual bundle interfaces, see the Cisco uBR10012 Universal Broadband Router SIP and SPA Software Configuration Guide.
Chapter 3 Cisco Cable Wideband Architecture Modular CMTS • M-CMTS Core—Contains the traditional functionality of a CMTS except for the downstream PHY. The M-CMTS Core provides CMTS functionality, such as DOCSIS MAC (media access control) and upstream QPSK and QAM demodulation. DOCSIS MAC includes upstream and downstream packet transmission services and MAC management message exchanges with cable modems. In the Cisco Cable Wideband Solution, the Cisco uBR10012 router is the M-CMTS Core device.
Chapter 3 Cisco Cable Wideband Architecture Modular CMTS Multiservice Architecture With M-CMTS architecture, the use of external edge QAM devices allows MSOs to use the same network resources for a video on demand (VOD) network and a Cisco wideband cable network. With updated firmware, some edge QAM devices can be used for VOD and for wideband channels though individual output QAM channels in the device cannot be shared.
Chapter 3 Cisco Cable Wideband Architecture Modular CMTS A MAC domain is responsible for all MAC Management Messages to the set of cable modems that are registered on that MAC Domain. A cable modem is registered to only a single MAC Domain. A MAC Domain provides Layer 2 data forwarding services between the CMTS and the set of cable modems registered to that MAC Domain.
Chapter 3 Cisco Cable Wideband Architecture Gigabit Ethernet Switch Functionality Quality of Service For quality of service (QoS) on a wideband downstream channel, a wideband cable modem can be assigned multiple service flows. Only Best Effort (BE) service flows are currently supported. The CMTS sends data traffic on a non-guaranteed best-effort basis. For the traditional DOCSIS upstream channel associated with a wideband channel, QoS capabilities supported are identical to those in DOCSIS 2.0.
Chapter 3 Cisco Cable Wideband Architecture Wideband Cable Modem Functionality The QAM channels on the edge QAM device do not need to be adjacent. If certain QAM channels have already been assigned to non-DOCSIS uses, the DOCSIS 3.0 Downstream Channel Bonding feature uses the channels that are available. The system does impose certain constraints. For example, if the QAMs are frequency stacked, certain QAMs will have to be adjacent.
Chapter 3 Cisco Cable Wideband Architecture Wideband Cable Modem Functionality A wideband channel uses the same DOCSIS frame format as a traditional DOCSIS channel uses. The channel just has more bandwidth. A new extended header for wideband has been added to the DOCSIS protocol. The extended header defines the logical wideband channel and a sequence number that the wideband cable modem uses for re-sequencing the wideband packets.
C H A P T E R 4 Implementing and Configuring the Solution This chapter provides implementation and configuration information for the Cisco Cable Wideband Solution, Release 1.
Chapter 4 Implementing and Configuring the Solution Wideband CMTS Configuration All wideband channels used on a fiber node and all associated primary downstream channels on Cisco uBR10-MC5X20 cable interface line cards must be configured to belong to the same virtual bundle interface.
Chapter 4 Implementing and Configuring the Solution Wideband CMTS Configuration Configuring the Wideband SIP and Wideband SPA The wideband CMTS components that require configuration include the Cisco Wideband SIP and Cisco Wideband SPA. Cisco IOS commands are issued on the uBR10012 router to configure the Wideband SIP and SPA.

Chapter 4 Implementing and Configuring the Solution Wideband CMTS Configuration Configuring the Gigabit Ethernet Switch A Gigabit Ethernet (GE) switch linking the Cisco Wideband SPAs and the edge QAM (EQAM) devices is optional except when more than two EQAM devices are required for two Wideband SPAs, or when video-on-demand (VOD) traffic and the RF channels for wideband channels are mixed on the same EQAM device.
Chapter 4 Implementing and Configuring the Solution Wideband Cable Modem Behavior Wideband Cable Modem Behavior This section provides information on the wideband cable modems and their interactions with the CMTS.
Chapter 4 Implementing and Configuring the Solution Wideband Cable Modem Behavior DOCSIS Configuration File for Wideband on Linksys WCM300 Modems The Linksys WCM300 wideband cable modem obtains a DOCSIS configuration file as it does in DOCSIS 2.0. For wideband operation, the file may contain three wideband-related Type/Length/Value (TLV) encodings.
Chapter 4 Implementing and Configuring the Solution Wideband Cable Modem Behavior The bonded channel enable option allows the provisioning system to require that a wideband cable modem operate in traditional DOCSIS 2.0 mode. When the bonded channel enable option has a value of 0 (disable), the CMTS ensures that a wideband-channel interface is not assigned to the wideband cable modem at registration time.
Chapter 4 Implementing and Configuring the Solution Wideband Cable Modem Behavior The configuration file used for the Scientific Atlanta DPC2505/EPC2505 wideband cable modem is identical to a DOCSIS 2.0 configuration file. DOCSIS 2.0 configuration file tools like the Cisco Broadband Configurator can be used to create configuration files for this modem.
Chapter 4 Implementing and Configuring the Solution Supported MIBs Consistent with DOCSIS 3.0, the assignment of multiple channels takes place at two layers. The lower layer is that of physical receiver configuration, or the Receive Channel Set, of the cable modem. The CMTS uses a specific subset of DOCSIS 3.
Chapter 4 Implementing and Configuring the Solution Known Restrictions • Traffic from different Wideband SPAs cannot be mixed on the same QAM port. • Scientific Atlanta DPC2505 and EPC2505 wideband cable modems support multicast traffic on the primary downstream channel only. These modems do not support multicast traffic on wideband downstream channels. Cisco Cable Wideband Solution Design and Implementation Guide, Release 1.
