DOCSIS 3.0 MAC
The DOCSIS 3.0 MAC on the Cisco uBR-MC20X20V is an internally developed Cisco feature providing dedicated
MAC layer hardware for line-rate performance in large-scale deployments. The DOCSIS 3.0 MAC hardware enables
scalability for thousands of cable modems and CPE, simultaneously providing hardware acceleration for
sophisticated security features including AES encryption while continuing to support older DOCSIS 1.x and 2.0
encryption features. Cisco’s DOCSIS 3.0 MAC design allows for unprecedented feature flexibility and robust defect
correction.
Interoperation with Cisco’s DOCSIS 3.0-Capable Wideband SPA
The Cisco uBR-MC20X20V supports the ability to build MAC domains with downstream channels being shared from
the DOCSIS 3.0-ready Cisco 1 Gbps Wideband SPA. The Cisco uBR10012 platform can be configured to support up
to 304 downstream channels in an Integrated or Modular deployment.
Flexibility with Cisco Software Licensing
The Cisco uBR-MC20X20V is available in three licensed options that offer customers a pay-as-you-grow model:
●
UBR-MC20X20V-0D: Includes base hardware and software licenses for 0 downstream and 20 upstream
channels
●
UBR-MC20X20V-5D: Includes base hardware and software licenses for five downstream and 20 upstream
channels
●
UBR-MC20X20V-20D: Includes base hardware and software licenses for 20 downstream and 20 upstream
channels
Downstream upgrade licenses for the UBR-MC20X20V-0D and UBR-MC20X20V-5D are available. Capacity
upgrades are thus a simple matter of upgrading the license on the existing uBR-MC20X20V rather than having to
purchase and deploy brand new hardware every time a capacity upgrade is required.
