Docsis chat

Hi Everyone!,

I have a cisco uBR7246VXR
Motorola C8U Upconverter
DOCSIS DS on 561MHz.
provisioned with freeBSD.
CM are Motorola SB4200 and SA WebStar for now

I have two ip pools one for cable modems 10.10.0.0/22
and another range for CPE 172.16.0.0/22
The current configuration allows two CPE behind the Cable Modem.

The situation is that cable modems receives IP address since you connect then to RF cable.
But when the CPE is an Access Point does not acquire ip.
You have to turn off the AP and turn it on again to receive IP.

Once you get ip, it takes hours working fine,

Hello,

...In eyes of a europe MSO for cable modem manufactors:

ScientificAtlanta ==> Cisco
Ambit ==> ubee
Thomson ==> Technicolor
Motorola ==> Compal

From the majors only Arris is still the same brand ;)

Hello

I've been working on setting up VOIP using ncs (packetcable) mta modems. I've been using Arris TM502G and Motorola SB5121 modems. So far, I've gotten the motorola to download the MTA config file, but I am having problems getting the Arris to ever request its MTA config.

Hello,

found out some TWG850-4U units in storage, nobody in the company knows who bought them or from where. They came with PacketCable firmware preloaded, bu we use EuroDocsis and SIP.

It would be a shame if they go to waste, and since we have no reliable Thomson dealer here (we switched to Cisco a while ago), if somebody has a eurodocsis sip firmware for these units, I would be gratefull if you could send it to me via email or post a download link for it.

in Cisco DPC3000 modem, the modem Status page show: Cable modem Certificate: uninstalled. What does this mean, and which from certs?

Hello,

we have a cable plant with telephony service and we use mostly Cisco EPC2203 modem/emta devices. We acquired a number of Cisco EPC2425 modem/gateway/emta devices, and my troubles started :).

Has anyone used the offline diagnostic image for Cisco's 5x20 cards?
Any advise or feedback?

Does anyone know if a diagnostic image is available for the MC20x20 cards?
I dug around Cisco's site but it's all skitter skatter so maybe I missed it.

Hello,
I am a senior network engineer with a 20+ year background. I am working with a small cable company (<200 subs) to install a CMTS 1000. I've configured it, set up tftp, dhcpd, and am using our ntp servers. I've gone through many of the configurations here, and I think I am pretty close.

I'm seeing the cable modem make a request at the cmts, and at the dhcp server. I see this at the CMTS..

CABLE: <> DA=ff:ff:ff:ff:ff:ff SA=00:0c:e5:24:7c:7a
SRC IP=0.0.0.0 DST IP=255.255.255.255 yiaddr=0.0.0.0 chaddr=00:0c:e5:24:7c:7a

I currently have one ubr with about 3000 users, 200 of them have static ip addresses. I am about to replace the single ubr with 2 ubr 7246 vxr's and need to split the plant to handle the growing load. which means I will have an avg of 100 static on each cmts. Does anyone know a why to config this network so I don't have to have 100 subscribers renumber their static ip addresses?
