Cisco The DOC SIS and MPEG linecard (base) for cBR RPHY
Part Number: CBR-CCAP-LC-40G-R=
Product Overview
The Cisco® cBR Series Converged Cable Access Platform 40G Remote PHY line card is specifically designed for Remote PHY deployment. While the 8 downstream by 16 upstream Converged Cable Access Platform line card is designed with downstream and upstream PHY modules and can run in both integrated CCAP and Remote PHY deployments, the 40G Remote PHY line card is designed to support Remote PHY deployment cost-effectively and exclusively as a purely digital card that does not support PHY modules.
A 40G Remote PHY line card is paired with a cBR CCAP 8x10G Remote PHY Digital Physical Interface Card (D-PIC) to provide 40G bandwidth to transmit DEPI and UEPI traffic over the D-PIC. In a Remote PHY deployment, Cisco cBR Series Converged Broadband Routers equipped with the 40G Remote PHY line card and D-PIC is the CCAP core. A remote physical device (RPD) is used to transfer DOCSIS frames between an IP network interface and a RF interface. The RPD does not participate in the DOCSIS MAC protocol. Instead, Remote PHY system provides an IP pseudowire that seamlessly transports the DOCSIS frames between the CCAP core and the RPD. As such, for most DOCSIS functions, the CCAP core system functions almost identically to an integrated CCAP. This preserves common functionality and features between the two systems.
The Remote PHY line card can be configured into a redundancy group to support N+1 fully protected, high-capacity configuration.
