 Used Cisco 5x20 Broadband Processing Engine
Part # Cisco 1-Gbps Wideband SPA
Product Description: 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; and
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.
The Cisco 1-Gbps wideband
shared port adapter (SPA) for the Cisco uBR10012 Universal
Broadband Router enables cable operators to offer high-speed
broadband connectivity at scale and to enable new IP services.
This product supports both the traditional DOCSIS 1.x and 2.x
cable modems and the emerging wideband solutions. The new Cisco
1-Gbps wideband SPA works in conjunction with the Cisco 5x20U
Broadband Processing Engine to meet the ever-increasing needs of
cable operators that are delivering IP-based data, voice, and
video services to an ever-increasing number of subscribers.
