Cisco 10k Upstream Analysis

Forums: 

Does anyone remember the commands to do an upstream snr analysis on a cisco CMTS? There used to be a windows utility here somewhere that would show the live SNR at the cmts but for the life of me I can't find it.

The original command I remember was
show controller cable6/0 upstream 0 spectrum 5 55 3

But this doesn't seem to work on the ubr10k revision I have.

TIA!

16x4 bonding

Forums: 

I have a PRE4 with IOS 122-33.SCH5 and I'm trying to create 16x bonding groups that cross the 24 frequency section of the 72/60 card. From all the advice and examples provided on this site, I believe I have a working config below but I'm not getting bonding on wideband 5/1/0:10 or wideband 5/1/0:11 even when I shutdown the rest of the wideband interfaces. Wideband 5/1/0:9 works fine. I'm not sure if this is IOS version or not since it allows the commands I need. I'm using a Harmonic 6G gateway if that is relevant. Any advice would be great.

16QAM for Station maintenance ATDMA docsis 3.0 CASA CMTS

Forums: 

Hi, i see Station maintenance in modulation profiles is in QSPK. QPSK is a very robust modulation and the cable modem will stay online down to a MER of around 12 dB, but subscriber data (shown in a-short and a-long) is transmitting at 64-QAM. The CMTS could report, via station maintenance that the modem looks just fine due to robust QPSK, but not for 64QAM.

Isn't it better to set the STATION to 16QAM to have a real idea of ​​the health of my network?

ingress noise cancellation crazy things

Forums: 

I guys, i have CASA C40g ,I currently analyzing a problem I have with an upstream physical port where when enabling the ingress cancellation command, the FEC and SNR corrections go crazy, with jumps from SNR 10 to 42 and uFEC more than 15%. If I disable this option everything is normal.
Question, will I have damaged the hardware related to noise cancellation in that physical port or is it something software?

SPA-24XDS-SFP issue

Forums: 

I'm getting "not modular-host capable" when trying to add 1/1/0 (SPA-24XDS-SFP) to the 3G60 72/60 card in subslot 8/1. I'm running IOS version 12.2(33)SCF3 on this particular CMTS. Is this the issue or do I need to possibly upgrade something else? Thanks.

what is the correct distribution between primary and secondary downstream carriers?.
the 4:1 ratio between primary and secondary carriers in DOCSIS 3.0 is correct ?

Thanks..

Know levels of cable modems in the CMTS

Forums: 

Hi

I have CMTS C100G Casa Systems and I want to develop an application with php that allows me to list the cable modems (mac)
and know which upstream port of the CMTS they are connected to and know their DSPwr(dB), USPwr(dB), DSSNR(dB) levels

My intention is to save this in a database.

For example, to identify the percentage of cable modems through an Upstream port that exceed the USPwr(dB) level by more than 50 dB or cable modems (mac) that have levels outside the expected range.

Help with Provisioning

Forums: 

Hi!

Does anyone have a PDF copy of the Arris 9.x "Firmware Guide/Provisioning Manual?" Also how do you setup CWMP option 43.1/125 on a Cisco/Moto/Arris CMTS or router?

Thanks,
Ben

Disable Docsis 2 modems

Forums: 

Is there any way I can stop Docsis 2 modems from coming online, either with an OID in a docsis config file, or via something on the CMTS (Cisco UBR 10k). We are in the process of phasing these out from our network and once done, we want to deny access to all modem types less than docsis 3.
