Cable Modem Termination Systems (CMTS): Architecture, Configurat

Is there a specific benefit that you would like information about?  DOCSIS 3.0 and IPv6 on Cable are specific features on their own.  You can certainly use them together but it's not necessary. 

Perhaps this link will help.

Last question from the live event that was not answered:

Is the wide band SPA only for 5x20 and 20x20 cards w/RFGW1 or 10?

Hi Eric,

I have some questions about CMTS, Is this device used to terminate any signals that come from network?

What is the main purpose of this device?

Thanks

Hi Fahad,

CMTS stands for Cable Modem Termination System.  In other words, all the Cable Modems in a specific market will eventully terminate or aggregate to a CMTS device.

CableLabs defines a CMTS as follows:

     The CMTS connects the operator's back office and core network

      with the HFC network. Its main function is to forward packets between

      these two domains, and optionally forward packets between upstream

     and downstream channels on the HFC network.

The HFC that they refer to is the Hybrid Fiber Coaxial network.  Slide #12 in the presentation illustrates this.

The Cisco Wideband SPA is only supported in the uBR10k platform.

The Cisco Wideband SPA is a single-wide, half-height shared port adapter that provides DOCSIS Network formatting to downstream data packets. The Cisco Wideband SPA is used for downstream data traffic only and is a key component for the DOCSIS 3.0 Downstream Channel Bonding and DOCSIS M-CMTS network architectures.

This means that you will need an external EQAM device which will receive the data from the Wideband SPA and

perform QAM modulation and RF upconversion.

Re: Cable Modem Termination Systems (CMTS): Architecture, Configuration, and Troubleshooting

Can I use diagnostic software (ubr10k-fdiagslc-mz.7_0.bin) to troubleshoot UBR-MC3GX60V? If not, kindly advise the version that will work. Thank you in advance.
