Cisco UBR-MC20X20V Cable Interface Card

The Cisco UBR-MC20X20V cable interface line card is a 20 by 16 inch card designed specifically for
the Cisco uBR10012 universal broadband router. This card transmits and receives RF signals between
the subscriber and the headend over hybrid fiber-coaxial (HFC) system. It has five downstream (DS)
ports and twenty upstream (US) ports. The line card supports five cable MAC domains (cable interfaces),
and the 20 DS and 20 US channels are dynamically associated with any of these five MAC domains. The
card has twenty US spigots and five DS spigots. Each of the US spigots supports either two-frequency
stacked US channels across ten ports or a single US channel across twenty ports. Each of the DS spigots
supports four-frequency stacked channels across five ports.
Note You must ensure that two DOCSIS Timing, Communication and Control (DTCC) cards are configured
on the Cisco uBR10012 router before installing the Cisco UBR-MC20X20V cable interface line card.

Cisco uBR-MC3GX60V Cable Interface Card

The Cisco uBR-MC3GX60V cable interface line card is a DOCSIS 3.0 compliant line card designed
specifically 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 cable interface line card has 20 US spigots for RF connectivity, which are
organized into 5 groups of 4 connectors each. Each connector group supports up to 12 frequency-stacked
US channels, with a default configuration of 3 US channels per RF connector.
The Cisco uBR-MC3GX60V cable interface line card has six Gigabit Ethernet (GE) interface ports
organized into three pairs for DS connectivity. Each pair supports 1+1 redundancy and supports 24 DS
channels in Annex B mode by default. The GE interfaces connect to an external Edge Quadrature
Amplitude Modulation (EQAM) device and provide M-CMTS compliant Downstream External PHY
Interface (DEPI) data.
Another unique feature of the Cisco uBR-MC3GX60V cable interface line card is the use of a front panel
display (FPD) to show the licensing status information of the US and DS channels.
