The migration to IP-based cable solutions just got a little easier with the Cisco® uBR‑MC3GX60V-RPHY Broadband Processing Engine (BPE). This high capacity, DOCSIS® 3.0-capable and C-DOCSIS/Remote-PHY-compliant line card for the Cisco uBR10012 Universal Broadband Router is shown in Figure 1. The new BPE has been streamlined, with upstream and downstream physical (PHY) layer functions relocated to the Cisco Coaxial Media Converter located at a remote site while MAC and DOCSIS software features are still retained in the center. With this new architecture and the introduction of a set of mature protocols, Cisco offers our cable customers with 1Gbps+ service and a smooth migration path towards an IP-based cable solution. With digital-optical and central control, the Cisco uBR-MC3GX60V-RPHY BPE is also easier to operate.

Figure 1.      Cisco uBR-MC3GX60V-RPHY Broadband Processing Engine

There are 72 DOCSIS downstream and 60 upstream channels per card, so the Cisco uBR-MC3GX60V-RPHY BPE supports the same benchmark for scalable, fast, and cost-effective DOCSIS 3.0 Cable Modem Termination System (CMTS) solutions maintained by the Cisco uBR-MC3GX60V Broadband Processing Engine (BPE). With the new Cisco uBR-MC3GX60V-RPHY BPE, the Cisco uBR10012 platform scales up to 576 modular DOCSIS downstream channels and 480 upstream channels, (approximately 24 Gbps of downstream throughput and 14.4 Gbps of upstream throughput) in a single, carrier-class chassis as part of our Remote-PHY solution. On top of this, with the introduction of virtual combining, the bandwidth can be further scaled in the Ethernet domain to support more CMC hosted upstream channels and as many CMC downstream channels as required. The limit for downstream channels is based on the available bandwidth to be delivered to and from each CMC. This evolution moves the traditional RF combining of multiple service areas into CMTS ports to the Ethernet domain, allowing virtual combining to greatly enhance network scalability.

Remote-PHY System Architecture

The Cisco Remote-PHY system consists of the DOCSIS CMTS core, Cisco Coaxial Media Converter (CMC), cable modem and supporting system. It implements broadband data and digital video access and forwarding, service configuration, and management and maintenance of CATV coaxial cable networks. The Modular Headend Architecture version 2 (MHAv2) is a set of open protocol standard recommendations specifically designed for Remote-PHY.

Figure 2.      Remote-PHY Standard Architecture

The Modular Headend Architecture (MHA) is a CableLabs® specification for a M-CMTS architecture that differs from the integrated CMTS (I-CMTS) architecture, which has PHYs internal to CMTS. The MHA includes DOCSIS External Downstream Interface (DEPI), DOCSIS Timing Interface (DTI), Operations Support System Interface (OSSI), and video-related specifications. MHAv2 is the extension of MHA, a new Layer 2 Tunneling Protocol Version 3 (L2TPv3)-based protocol. Upstream External PHY Interface (UEPI) is defined for upstream DOCSIS MAC management and data packets encapsulation. It supports the combination of DEPI and UEPI in the remote side, hence it is also called as DOCSIS Remote PHY. General Control Plan (GCP) protocol is also introduced as the general control plane protocol used to start, run, and configure the CMC.

In the MHAv2 architecture, both downstream PHY and upstream PHY are deployed on the remote side, which is called CMC. Please note that the CMC has to work with the Cisco uBR-MC3GX60V-RPHY BPE line card that has the same functionality as the existing Cisco uBR-MC3GX60V BPE except for the RF and PHY-related features. The CMC has both radio frequency interference (RFI) and Gigabit Ethernet (GigE) interfaces while the line card only has GigE interfaces for both upstream and downstream.

DEPI is based on L2TPv3 and is the downstream link between the downstream MAC and remote downstream PHY, which is inherited from MHA and contains the forwarding plane protocol. UEPI is also based on the L2TPv3 and is the upstream link between upstream MAC and upstream PHY.

In the MHAv2 architecture, the CMC and the digital fiber network are transparent to cable modems. The CMC is managed in the CMTS core with GCP. The cable modem and provisioning system do not change. With this approach, Cisco CMC for Remote-PHY has some of the least complicated electronics in the cable field, providing better reliability and lower cost.

The MHAv2 with DEPI and UEPI has been adopted by CableLabs and the China State Administration of Radio, Film, and Television (SARFT) for inclusion in the China DOCSIS (C-DOCSIS) specification.

Remote-PHY System Key Benefits

   Preserves the centralized software structure of the CMTS and rich feature sets. Allows for future software upgrades without requiring upgrades of the numerous remote nodes in the field.

   Requires a small amount of hardware and software in the remote node to keep the device relatively simple and stable. This provides many operational advantages, including less need for troubleshooting, normal operation and evolution. The simpler the hardware, the less chance of failure. Since most of the intelligent software resides in the headend, upgrades are easier since upgrading thousands of nodes in the field is not necessary.

   Supports Ethernet-based networks such as Ethernet Passive Optical Network (EPON), Gigabit Passive Optical Network (GPON), and Layer 2 Metro Ethernet. This gives customers the flexibility to cost-effectively select which transmission network is most appropriate to their needs.

   Preserves the sophisticated DOCSIS quality of service (QoS) assurance mechanism to help ensure end-to-end QoS. The granularity of scheduling is per service flow-based. In addition, there is no mapping needed from DOCSIS service flow to Ethernet packet, virtual LAN (VLAN).

   The CMC and transmission network are transparent to the CMTS and cable modem so the Remote-PHY has no effect on the existing CMTS and cable modem. Instead, the architecture allows the use of digital Fiber.

Key Features and Benefits

Shared Upstream and Downstream Channels (Virtual Combining)

Upstream and downstream channels on the same GE port on the Cisco uBR-MC3GX60V-RPHY BPE can be grouped into multiple channel groups. One downstream channel can be shared by multiple channel groups. The set of downstream and upstream channels in each channel group can be shared by a maximum of four CMCs, which enhances the channel utilization and the number of CMCs connecting to them. By implementing upstream sharing, one Cisco uBR-MC3GX60V-RPHY BPE can supports up to 60 CMCs with each CMC having four active upstream channels and can support 240 CMCs with each CMC having one active upstream channel.

GE Connectivity for Downstream and Upstream

Unlike traditional CMTS line cards, there are no RF ports on the Cisco uBR-MC3GX60V-RPHY BPE and no RF connectivity is needed. The CMTS reduces to an “IP only” chassis and no longer needs direct access to the plant RF cabling. This in turn eliminates the need to run analog optical and coaxial cabling to central locations to make best use of a dense CMTS chassis.

Cisco Software Licensing Flexibility

The Cisco uBR-MC3GX60V-RPHY BPE still provides true cost flexibility for operators with licensing options that offer a pay-as-you-grow model. Licensing features include:

   Base hardware and 16 upstream and 16 downstream channel licenses constitute the minimum configuration supported.

   Additional optional licenses are available for purchase up to the full capacity of 72 DOCSIS downstream (or 54 EuroDOCSIS downstream) and 60 upstream channels.

   The Cisco Software Licensing (CSL) infrastructure provides an operationally simple licensing experience.

The ability to purchase and activate downstream and upstream channels as needed through software licensing allows cable operators to closely match their capital expenditures to their growth requirements. The sharing of licenses to multiple CMC decouples CMTS licenses from the CMC channels. The central CMTS licensing effectively becomes a bandwidth capability purchase - the bandwidth purchased being shared as required by CMTS configuration to all connected CMC. Operators can thus reduce their operational expenses by designing their DOCSIS networks to accommodate future growth by simply installing upgrade licenses to add bandwidth when needed to existing connected CMC.

Effective CMC Management

CMC management is supported with the GCP protocol. The detailed management function includes CMC statistics collection (e.g., downstream and upstream PHY counter and CMC status data, CMC status notification to notify CMTS about a specific event such as a critical issue on the CMC, and environmental events).

Notes on Licenses

   If purchasing multiple line cards, each line card in the order must have the same number of upstream and downstream licenses. Upgrade licenses may be purchased in case customers need line cards with different licenses.

   eDelivery allows for electronic delivery of purchased license product activation key (PAK).

   Partial fulfillment is supported. If customers wish to purchase upgrade licenses for multiple hardware devices (for example, if they wish to upgrade all their Cisco uBR-MC3GX60V-RPHY BPE), partial fulfillment allows all upgrade licenses to be generated using a single PAK if the customer desires. This can greatly increase operational ease of license upgrades.

   Partial fulfillment is supported with Cisco License Manager (CLM).

   Downstream and upstream upgrade licenses can be mixed and matched under a single L-MC3GX60V-SWLIC= PAK.

   Return materials authorization (RMA): Cisco Services will replace faulty hardware with hardware that has no downstream or upstream licenses. Customers will need to transfer licenses from the failed board to the new board to make it operational.

   uBR-MC3GX60V-RPHY shares the same software licenses with existing uBR-MC3GX60V. However, at the moment, the software licenses on uBR-MC3GX60V and uBR-MC3GX60V-RPHY are not interchangeable.

Cisco Services
