Cisco Remote-PHY Solution

Driven by market evolution towards triple-play services, cable operators in emerging markets are seeking standardized and digital fiber-based solutions for economical and future proof access technologies. Much of the demand is driven by the need to provide higher bandwidth packet transport for Internet connectivity, video and voice services. DOCSIS® is known as a standardized technology for services over cable and thus has strong interoperability between system providers and robust Quality of Service (QoS) methods, ensuring packet delivery during periods of network congestion. Traditionally, DOCSIS runs on linear fiber (or HFC) to provide service and is not naturally applicable for digital fiber. However, Cisco has bridged the gap by inventing a new access technology called Cisco Remote-PHY.

Cisco Remote-PHY (a.k.a REMOTE-PHY) enables cable operators to deploy DOCSIS-based networks over digital fiber while obtaining all of the benefits of using standards-based equipments. These benefits include the utilization of scalable, cheap and easy to operate digital fiber, standardized and proven QoS for various services, lower cost, and wide availability of both cable modem and set-top box systems. Furthermore, with deep fiber, the optical noise contribution to SNR is eliminated. As a result, the remote QAM modulator runs at higher orders of modulation as compared to a centralized QAM modulator. Cisco Remote-PHY is apt where digital deep fiber is preferred.

This document presents an overview of using Cisco Remote-PHY as a solution for digital fiber and DOCSIS pursued cable operators. It provides a cost-effective digital fiber-based DOCSIS solution that uses Ethernet PON (EPON), Gigabit-capable Passive Optical Networks (GPON), or Metro Ethernet (MetroE) as transmission network between the CMTS and CM, which gives customers an optimal option to utilize the Passive Optical Network (PON) technology and DOCSIS in the same network.

New Hardware Features in Cisco IOS Release 12.2(33)CX

This section describes the new hardware features in the Cisco IOS Release 12.2(33)CX.

Cisco uBR-MC3GX60V-RPHY Line Card

Effective with Cisco IOS Release 12.2(33)CX, the Cisco uBR-MC3GX60V-RPHY Line Card is introduced for the Cisco Remote-PHY solution.

The Cisco uBR-MC3GX60V-RPHY line card is DOCSIS 3.0 compliant and is designed for the Cisco uBR10012 universal broadband router. This line card conforms to the Modular CMTS (M-CMTS) architecture and has the capacity to support up to 72 downstream (DS) and 60 upstream (US) channels.

The Cisco uBR-MC3GX60V-RPHY line card has six Gigabit Ethernet (GE) interface ports organized into three pairs, which connect to the Cisco CMC device via EPON, GPON, or Metro. Each pair supports 1+1 redundancy for the Metro Ethernet ports. The Cisco uBR-MC3GX60V-RPHY line card supports 24 downstream RF channels and 20 upstream RF channels per Gigabit Ethernet port. The Cisco uBR-MC3GX60V-RPHY line card has a front panel display (FPD) to show the licensing status information of the US and DS channels.

For more information, see the Cisco Remote-PHY Solution Guide document.

Cisco Coaxial Media Converter

Effective with Cisco IOS Release 12.2(33)CX, the Cisco Coaxial Media Converter (CMC) is introduced for the Cisco Remote-PHY solution. Cisco CMC acts as the edge QAM (EQAM) in the Cisco Remote-PHY architecture. It is located between the Cisco CMTS and the cable modem, and controlled by the Cisco CMTS router. Cisco CMC has network interfaces on one side connecting to the fiber (digital and linear) portion of the Hybrid Fiber Coaxial (HFC) plant, and RF interfaces on the other side connecting to the coaxial portion of the HFC plant. The RF output of the Cisco CMC can be combined with other services, such as, analog or digital video services. It uses the linux operating system Cisco CMC OS 1.0. Most of the Cisco CMC configurations are performed on the Cisco CMTS router.
