Docsis chat

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.

My e-mail is warlord (at) blwireless (dot) net .

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?

Dear all,

Our company has a new ubr-10k machine, and we try to log its status recently.
Is it possible to dump the amount of connected cm, the amount of connected cpe, SNR and Power level of each interface.
Ex. Cable5/0/1/upstream-0 ; SNR(US):34 ; DS TxPower:0 ; CM:12 ; CPE:30

Thanks,
Letea.

Hi,

As a rule of thumb, I like to use the default settings for the upstream cards in the Arris 1000 and 1500 CMTSs. But, is there a better way? For example, if I have some stubborn modems that won't connect can I set one card to be sort of a "catch all" that gets modems with less than good signal levels? I guess what I need is a cheat sheet for all of those parameters in the upstream cards:

admin-status up
frequency 29950000 hertz
width 3200000 hertz
power 20 tenths-of-dBmV

Hi all,

I really need help with this one and am ready to pay for help. My CMTS 1500 keeps rebooting. Here are some of there errors I get on the console:

freeing buffer twice 0xa06c3000, caller 0x8011a494, callers caller 0x801a467c

EH_event: fatal event: Internal inconsistency in Upstream Scheduler. Extra: 9,0,00000000,00000000,00000000

EH_event: fatal event: Internal inconsistency in Upstream Scheduler. Extra: 9,0,00000000,00000000,00000000

Looking for documentation for their CMTS products.
