The Cisco uBR-MC88V is capable of eight downstream (Annex A or Annex B) and eight upstream channels. The
port count remains exactly the same as the Cisco uBR-MC28U, with two downstream ports and eight upstream
ports. This enables the Cisco uBR-MC88V to offer a simple upgrade path from the older line card used on the Cisco
uBR7200VXR platform without any change to the cable wiring. Each downstream port is capable of carrying four
frequency-stacked downstream channels. Each downstream channel is configurable as part of DOCSIS 3.0 channel
bonding or DOCSIS 2.0/1.x channel. The line card also supports an extended DOCSIS upstream frequency range of
5 to 65 MHz and downstream of 70 MHz to 1 GHz for DOCSIS operations.
Features and Benefits
Fully DOCSIS 3.0 Capable
Fully CableLabs
®
and EuroCableLabs DOCSIS 3.0 capable, the Cisco uBR-MC88V supports downstream and
upstream channel bonding at a DOCSIS line rate that enables cable operators to offer very high-speed data services
to subscribers. The line card supports bonding of 4, 8, and even more channels and other full DOCSIS 3.0 features
including IPv6, multicast, Advanced Encryption Standard (AES) encryption, and Synchronous Code Division Multiple
Access (S-CDMA).
High Port Density
The Cisco uBR-MC88V supports eight DOCSIS 3.0 downstream channels through two quad-stacked physical
connectors and eight upstream channels each on a unique physical connector. It significantly expands the capacity
of the Cisco uBR7200 Series Universal Broadband Router to address growing subscriber bandwidth demands and
enable cost-effective scalability of services.
Superior RF Performance
The line card is compliant with DOCSIS Downstream RF Interface (DRFI) specifications and is designed with an
extended frequency range up to 1 GHz by using a highly integrated and low-power-consumption upconverter. With
the advanced spectrum management, ingress cancellation, and S-CDMA, the Cisco uBR-MC88V will mitigate
ingress noises in the hybrid fiber/coaxial (HFC) plant to achieve better RF performance.
Rich Cisco Technology-Specific Features
The line card supports Cisco technology-specific features such as Dynamic Bandwidth Sharing (DBS), advanced
spectrum management, and Subscriber Traffic Management (STM). DBS is the dynamic allocation of bandwidth for
wideband and integrated cable interfaces sharing the same downstream channel, which allows each channel to
claim the bandwidth unused by others. The DBS feature interacts with DOCSIS 2.0 load balancing to fully utilize
bandwidth resources. The STM feature allows service providers to identify and control subscribers who exceed the
maximum bandwidth allowed under their registered quality of service (QoS) profiles. This feature helps ensure that a
minority of users will not consume a majority of the bandwidth in the cable network.
