Docsis chat

Hi,
I'm fairly new to the DOCSIS arena and am having trouble understanding a few, what I consider to be, key points relating to the DOCSIS RF spectrum and availability to services over an HFC Cable network.

1. What is (or is there any) separation between each adjacent Downstream or Upstream channel in the DOCSIS/EuroDOCSIS spectrum?

(DOCSIS uses 6MHz and EuroDOCSIS 8MHz channel widths for downstream as a example. What is the spacing between each channel and is this spacing (if present) the same for all Upstream channel widths? i.e. 200KHz-6400KHz).

Hello!

How to configuration DHCP on Bsr 64k ? not using external server DHCP. i don't find manual giving Bsr 64k.

Thanks a lot

Hi,

is there any MIB object to change upstream channel id on cablemodem via SNMPSET? I only know how to _VIEW_ the Channel ID!
I'm trying to change this ChannelID (Frequency) like CASA CMTS do on Load Balancing?!

I'm using ARRIS TM602 and Thomson 540,420.... cablemodems.

Thanx.

Hello,

I'm a cable guy, but I have a customer that has wireless DOCSIS with an Arris CMTS 1500. His upstream SNR at the CMTS is about 10db. In the cable world that's bad. Is that bad for wireless too? my understanding is that DOCSIS is still DOCSIS over wireless, cable, glass or two cans and a string.

Thanks,
Eric

I'm trying to configure my UBR 7246 VXR to work with my 2 ISPs and i just can find the way to do it.
I have 2 ISPs, that till now were connected to 2 separate CMTSs & routers (because we do NAT).

What I'm trying to do is to eliminate my Arris CMTS and just use the CISCO UBR 7246 VXR.
What is the best way to do it? can i separate the CMTS ( 2 cards for each ISP - 12 upstreams) ? or can i route it if i give different ranges to the modems ?

Thanks,

Thanks so much.

Hi all,

Does anyone have a neat way to give CPEs a public static IP? There's no point in giving one to a CM. That's just a waste. They can have a private IP. In the dchpd.conf file I can statically assign a public IP using the CPEs mac address, but I want to somehow give a subscriber a public IP with only their CM mac address. Whatever they plug into that CM I want to give their Public Static IP. I know it can be done because my large monopoly provider does it. I can't let them be better than me at anything. :)

Thanks,

Hi all,
I need help with cmts motorola bsr2000. I have cmts, a need get to cmts to default state. cmts arrived with clean CF card, and with password to "privileged exec mode". I finding out password (unfortunately).
I made next procedure. during cmts booting I press key on state "Press any key to stop auto-boot", next I press E (erase nvram flash file system) and next R (reboot with lear(longer)). Now cmts during booting finished on text: Error loadinf file: errno = 0x3c. Cant load boot file.
I need boot image or boot files, which I copy to CF card for correctly booting.

Hi,

I am searching for C4 / C4c Cacti template everywhere with no success.

I will be very grateful if anyone can share it.

Thank you in advance!

does anybody know how to manage Netgear CME31T modem via Command Line Interface? (Telnet/CLI) What commands are available?
Is there a special Diagnostic Modem vers. with shelled firmware, which allows to log onto the modem and set diagnostic switches to trace and log what is happening on the network, for tracing intermittent and otherwise difficult faults?
