Description

Cisco SPA-24XDS-SFP 1-Gbps wideband SPA for the CMTS

Overview

The distributed and scalable architecture of the Cisco uBR10012 Universal Broadband Router can be expanded using the Cisco 1-Gbps wideband SPA to meet the most challenging large-scale IP service needs of cable operators. More specifically, the Cisco 1-Gbps wideband SPA delivers critical cable modem termination system (CMTS) functions, such as:
● Capacity for 24 DOCSIS Annex B and 18 Annex A downstream channels
● Integrated DOCSIS Media Access Control (MAC) processing
● Connectivity to third-party edge quadrature amplitude modulations (QAMs) using dedicated
dual Gigabit Ethernet interfaces
● On-board packet-bonding engine that stripes IP packets across multiple DOCSIS
downstream channels
The Cisco 1-Gbps wideband SPA performs all traditional and wideband DOCSIS processing of
egress packets, including BPI+ encryption. The wideband MPEG packets are aggregated and
encapsulated using the DOCSIS 3.0 packet-bonding technique (that is, User Datagram Protocol [UDP], IP, and Ethernet protocols [that is, packets are DOCSIS over wideband MPEG over UDP over IP over Ethernet]).
Each Cisco uBR10012 chassis can support up to two Cisco 1-Gbps wideband SPAs by utilizing a carrier card that occupies slots 1 and 2 in the I/O portion of the chassis. Equally important, these SPAs work in conjunction with the existing Cisco 5x20U Broadband Processing Engines to more than double the available downstream bandwidth of the Cisco uBR10012 system.

Specifications

The Cisco SPA-24XDS-SFP 1-Gbps Wideband SPA is a powerful networking component designed for the Cisco uBR10012 Universal Broadband Router.

Purpose and Compatibility:

- The SPA enables cable operators to offer high-speed broadband connectivity at scale and supports both traditional DOCSIS 1.x and 2.x cable modems, as well as emerging wideband solutions.
- It works seamlessly with the Cisco 5x20U Broadband Processing Engine to meet the increasing demands of IP-based data, voice, and video services for a growing subscriber base.

Key Features:

- Channel Bonding: The SPA expands the current 30-Mbps service portfolio options up to 240 Mbps, allowing efficient video delivery over IP. It also offers flexibility to provide multiple unique service tiers concurrently and scale services for new subscriber growth.
- Industry-Leading Port Density: By providing more downstream capacity to the Cisco uBR10012, the SPA significantly reduces per-port cost and doubles the available downstream bandwidth when used with existing 5X20 RF line cards.

Technical Specifications:

- The SPA occupies one single half-height SPA slot and features dual Gigabit Ethernet interfaces with Small Form-Factor Pluggable (SFP) connectors.
- It is hot-swappable, and either right-side subslot (0 or 1) can be used.
- Dimensions: 6.75 x 0.8 x 7.28 inches (17.5 x 2.03 x 18.49 cm), weight: 0.5 lb (0.23 kg).
