Docsis chat

Hi folks !

Little question, I am trying in my lab to measure the maximum upstream speed with Docsis 1.1/2.0 CM and CMTS and I am blocked with a maximum speed of about 2.5 Mbps independently what the CM vendor/model it is (tested with Motorola, Cisco/Scientific Atlanta, Technicolor/Thomson). Upstream has 3.2MHz bandwidth, and QAM16 modulation.

If I take a Docsis 3.0 CM with the same CMTS configuration, I have the same limitation.

How important is DHCPv6 Server to your network? How much are you prepare to buy a DHCPv6 Server?

I've been tasked with adding DOCSIS service to some apartments we manage. Most of my experience so far is in running the ethernet network at the adjacent property and building/maintaining the analog cable system at that property. We are about to launch a Dish Network QAM system for both properties as well as cable modem service for the smaller property where we only have existing RG6 to work with. There are 64 units.

Hi, I need change web acces password to wifi configuration in DG950S. (In CFG files) Modem requires password of the day.
WBM750 requires to advanced menu also pass.of.the.day but I can change this password in CFG files by snmpset.
SnmpMibObject .1.3.6.1.4.1.4115.1.3.4.1.2.4.0 String "ahdashhfasssaha";
This command isnt functon in DG960S. But Mib is identical (or no?)
Sorry for my english.
Have a nice day and thank you for reply

cable modem does not come online. settings ok! is the same as two others that have CMTS. I've had this problem and was solved by upgrading the FPGA. anyone knows how.

I'm trying to find SNR, RX power and Up channel for Wideband modems.

Docsis 2.0 information is accessable via:
docsIfCmtsCmStatusSignalNoise
docsIfCmtsCmStatusRxPower
docsIfCmtsCmStatusUpChannelIfInd

But for all modems that use wideband it is zero or undefined.

I can see information on the cmts, is their a standart MIB or should i expect this to be CMTS specific?

I'm trying to enable BPI + with a SB5100 modem and am having a problem ... He is on the status of online (pt). Theoretically everything is ok, but do not get IP and CPE modem is not stable (reboot after some time synchronized).

He is with the firmware-ga-2_3_9_0 00_sb5100_nosh and provisioned with DOCSIS 1.1 and BPI +
I do not know exactly what might be missing ...

Does anyone have any tips about the problem?
Thanks !

I like the new layout despite the ads, but it needs the search engine!

We have recently upgraded our Arris C4 CMTSs from version 5 to version 7 Docsis3.0

We already have a large number of Dcosis2.0 emtas deployed and we have noticed that since the upgrade, the subscribers are not rate limited to their subscribed service according to the service flow definition in their CM config files (eg. 10M down, 20M down etc), but all emtas, irrespective of CM config, achieve download speeds in excess of 40Mbit

We have tested the same SFs in config files for Docsis3.0 emtas, and on Docsis3.0 emtas rate limiting works with no problem
