Docsis chat

Hi Guys,
I am testing Arris C4c.At work we are using pppoe for the user.Currently we have Cisco Ubr 72xx so pppoe terminates directly on it.
Arris doesnt supports direct PPPOE termination, so as per cisco site we are trying to do L2tp Tunnel between C4c & Cisco NAS which supports PPPOE.
Arris guys are also searching for way to do it but no luck.Can anyone doing something similar on Arris/BSR64000 please help me.

Thanks

Hi Guys,
We are testing some new D.3 cmts.We need test/acceptance case/template for cmts.Tried to do on our own but we are
stuck with various modulation profiles & throughput.Which is not only thing cmts do.Can anyone share the test case.
Means I am asking one worksheet for way to do it.Or someone guide me what are the things to be monitor/done.

Thanks

Hi all,

I’m quite new with the DOCSIS technology. Maybe it’s a simple question, so don't think that I’m a fool ;)

We created a test setup with the following components:
1. Arris C4 CMTS
2. Arris WBM760B (High Speed Data) This part works
3. Arris TM722B (High Speed Data and VOICE) Only the High Speed Data works
4. Debian DHCP and TFTP server for provisioning

The problem is that we aren’t able to get the EMTA’s online for a TM722B modem. So everything works fine except the voice part. We only see DHCP requests from the CMAC’s, is this normal?

Hello,

How long does the 1500 store the offline modem history after the modem has been offline? I realize once the CMTS is restarted it's gone. I thought that the purge-fdb command was supposed to clean that out. So I guess my final two questions are: How do I clean out offline modem data and what does the purge-fdb command actually do?

Thanks,

Does anyone know what OID I would poll to get the temperature of the Arris C3?

Thanks,

Can anyone advice me on what a fair cost would be for a Residential and Business line.

Is is cheaper to DIY or outsource. And if you Outsource whats fair price to pay.

Hi Group

I have a BSR2K and I want to change DS modulation from 64qam to 256qam to increase throughput. Is there any chance cable modems go offline when changing modulation? Issues related with this? I know in US modulation change, the SignalQuality goes down but I think is not the same in DS.

Thanks in advanced.

Hi!!

I have a problem, i want to make nat using Motorola BSR 1000, and i don´t found nat function in the IOS, and i want to know if it is possible in that CMTS ???

PD: i want to make nat using a pool of public ip addresses using that Motorola BSR.

Thanks.

Hi All,

i've been lurking the forum for a while and it helped me a lot al ready!
i got the whole system online including MTA's!

But now i want to split up the CPE network to different subnets, so this can be filtered by a transparant firewall.
e.g.

CM 1 - ip 10.20.0.5\24
CPE 1 - ip 172.16.0.10\24
CM 2 - ip 10.20.0.6\24
CPE 2 - ip 172.16.10.10\24

Provisioning :
Linux Debian distro
DHCP ( 2 pools, 1 for CM, 2 (or more) for CPE)
TFTPD
DNS
NNTP
MYSQL (DB with mac address + ip address CM network) --> managing our static hosts.conf for provisioning the CM's
+/- 300 CM

I think I mentioned before, I'm new in this.. so sorry if i bother too much.
and thanks if you understand me.
im very interesting in learn everything I can in this environment.

USING: uBR7246VXR

I recently got interested in estimate the consumption of bandwidth.
how could i do this...

i know how much total bandwith is generated monitoring the internet router directly.
Also i can generate graphic with mrtg tool.
but i cant know how that traffic is distributed in the cable modems.

example:
Total traffic was 1460kbps 2:00 pm
if I have only 3 cable modem connected
