Docsis chat

Is there anyway I could change the DOCSIS MTU from 1500 to 1600?

I don't know if this a folly, so I apologize.

Regards

Hello-

We are looking to move some inventory- We are are reseller of IT/Network gear- In business for 20 years.

Here is some of what we have that is ALL CMTS related.

4x Arris C4 Docsis 3.0 w/ redun SCM2, RCM (10G) 7x 16D's, 7x 12U's ($45,000 each
4x Arris C4 Docsis 3.0 w/ 1SCM, 1RCM, 3x16D, 3x 12U (email for price) ($30,000 each
2x Arris C4 Docsis 2.0 w/ 2 SCM2, 2xFCM 15x 1D12U cards (plus the rear cards) $12,500 each

8x Arris C3's 1x6 $2900 each
5x Arris C3 1x2's $1800 each

I hate having to support a test bed of physical modems and looking for some sort of Docsis Modem Emulator. Does anyone know of one?

I have the doubt if it's possible to bond 1 DS port with 4freq. on one MC20x20 to another DS Port with 4freq. on another MC20x20 ? The goal is to have with 2 MC20x20 LineCard 5 DS Bonding Group with 8freq. each.
From my point of view, it's not possible.

Hi all

I have a ubr10k with 3x MC20x20 cards .

Currently for docsis 3.0 modems in DS and i have config with bonded up to 8 channels . Goal is to add 4 channels more to configuration but i want to done that with RFGW1
I would add WB SPA card into ubr10k , and connect it to rfgw1 .

Does anyone done that ? How to bond 4 or 8 DS channels from mc20x20 with 4 channels on rfgw1 ?

Thaks a lot .

I've run into this odd problem twice now, wondering if anyone else has seen a similar problem.

In both instances the following is common;
Problem only occurs with DOCSIS 3 modems regardless of manufacturer, but not DOCSIS 2 or older.
CASA CMTS using cable-helper (A 2200 and 3200)
Windows DHCP Server (Windows 2000, and 2003)

I have identical configurations with Linux DHCP servers that do not experience this problem.

I have a uBR7225VXR with 2 uBR-MC88V line card, and i want to configure it 16 downstreams bonding. anybody can help me?

I've a doubt about the possibility to configure a UBR10k (PRE2 + 4x MC5x20) and RFGW-1 EQAM. I would like to configure two nodes with 8DS each (16DS in total) exclusively from the RFGW, so we will use the US from the MC5x20 LC and 16 DS from RFGW, no DS will be used on LC. Is this possible ? How could I adapt actual config. (attached) to achieve such configuration ?

Thnks,C.

we have CMTS Arris C4 (2x16D 6x12U). frequency distribution, fiber-node and supervision:

Someone have a CM config file to the L2VPN with ubr10k?

Tks
