Docsis chat

During the marketing process, Jinghong sees a huge potential for satellite TV service providers in providing Internet service. The satellite TV providers has a coaxial distribution network, which allows Internet services with DOCSIS technology applicable.

The solution of Internet over Satellite TV network from Jinghong requires very limited investment both in time and in harware, simply by adding headend equipment and DOCSIS cable modems at users end, it is highly practical to bring extra value to existed coax network.

I'm hoping someone here can clarify a couple of statements about Receive Channel Profiles (RCP) I came across in CM-SP-MUPLIv3.1.

Regarding D3.1 CMTSs:

From the 1st paragraph of 8.2.4.3: A CM registering on a DOCSIS 3.1 CMTS MUST NOT communicate its receive capabilities using RCP encodings.

From the last paragraph of C.1.5.3: The CM MUST NOT send RCP encodings to a DOCSIS 3.1 CMTS.

Regarding D3.1 CMs:

Hello everyone,
I have Cisco ubr7246 CMTS,

Hi

We recently started testing the pre-equalization in our cisco ubr10k

The SNR increase in some case was very good

But after a couple of days we started getting complains from customers that their modems were resetting

In all cases these were docsis 2 modems

We disabled the load-balancing feature and the trouble went away

We re-enable load-balancing and the trouble came back

We disabled pre-equalization and the trouble went away

Hi all,

I need your help. I need make a cable filter group to filtering all ports less than 1024 but in the C4 cli I can't create this filter for port range.

Someone have any suggestion for this issue?

Thanks.

Hi for All,

My log file is full of following errors:

Hi,

I would like to know how can I use the Arris C4 CMTS as M-CMTS.

I know the Cisco version: 3Gx60 with gigabit DEPI tunnel and any RFGW. (1 or 10) There is a time server what connected both.
But not clear for me how can I make this with Arris .
Arris have RFGW too called Arris D5.
The D5 has DTI port for the time server, it is clear.

On the C4 chassis where is the DTI port?
Where are the ports for DEPI? Perhaps the RCM ports are reconfigurable?

Thank you!

After a recent RFGW install, we have a handful of Motorola SB6120/SB6121s that won't bond to wideband channels. We know it's a firmware problem because we have other modems on newer firmware that are working.

Would anyone be able to help me find firmware and the CVC for these?

If you want to ping me off list - email: skyler dot blumer at zitomedia dot com

Can anyone advice if D3.0 modem parameters are fine? What settings can be adjusted possibly?

Hi ,
I am using CISCO CBR8 CMTS using 8 DS with 2 U/S channel bonding . Issue is that , modem is releasing both D/S and U/S channel bonding and locking on singh D/S and U/s channels however RF level is ok with good SNR. On restart of cable modem is locks all 8 D/S and 2 U/s for some time and after couple of hours same issue. This issue is across all ports/ Line cards

Pl help.
