Docsis chat

I have a CMTS BSR1000 and the firmware version currently have is 2.0.1.10.PRRU.

Does anyone know which is the latest version?

Thank you

Dumb question but how may CPE's can a docsis 1.0 CM file allow? Is there even a limit? I am trying to come off of a cable modem (Building A) that has a static public ip and wirelessly send ethernet across a lake using two mikrotik 411 routerboards then go into a CMTS again (Building B). I do not desire to NAT behind the second CMTS so i am wanting to allow public IP's (CPE side) on my class c to tunnel through.

Hey, smee again.

Need more help :( I am stuck at different end: my MTA's get an IP address. However, after DHCP ack package, I never get to see TFTP request from MTA at my provisioning server. What strikes me as very odd is some sort of the routing problem that I cannot get hold of. I have 3 networks - 2 fixed subnets / IP addresses for both CMs and MTAs, and 1 pool set up for CPE. I use ISC-dhcpd, fourth network is defined just for the sake of the dhcpd.

Hi,
I'm using a Terayon BW3200 with Motorola 5101 modems. The maximum download speed I get is 12 Mbps. Would like to know if this is the maximum speed I can achieve with these hardware. BTW, I've a DS3 Internet connection, getting same result with local servers.

Thanks,
Christian

Hello,

I'm working on a system that uses a C3 and wireless DOCSIS. I just need to increase the SNR. currently the down SNRs are from 22 db to 32 db. I'm very familiar with DOCSIS. Does wireless use the same standards? Down power -18 to +18, Down SNR should be about 30db, Up power should be about 45db but can't go over 61db, Up SNR (read at the CMTS) should be about 30db??? Should I start tweaking the cm config file or the modulation profiles. The C3 is licensed for SCDMA, should I use that or TDMA or ATDMA? I have a plan, but would just like some opinions.

Hi, all

I run fedora with docsis_server, whenever I check processes on the server, there is a TON of dead (defunct) processes for docsis_server. While I know I can resolve this with cronned script, I wonder do any of you have idea why is this happening?

Can somebody confirm this. I have situation where docsis_server 3.5 sends wrong IP address in ACK packet for cable modems. It is IP+1 or IP+2 from value in OFFER packet.

Some of the cable modems doesn't mind this, but some of the do, and they end up stuck in init(i)...

select * from dhcp_log;

Hi,

I'm new to docsis software.
I installed: DOCSIS Configuration File creator, version 0.9.5
on FreeBSD 7.1.
During creation :docsis -e tol.txt key_file tol.cm
I received :

Final content of config file:
------------------------ cut
Main
{
NetworkAccess 1;
SnmpMibObject
SnmpMibObject experimental83.1.2.1.4.1 String "public" ;
SnmpMibObject
SnmpMibObject experimental83.1.2.1.6.1 String "@" ;
SnmpMibObject
SnmpMibObject
SnmpMibObject
SnmpMibObject
SnmpMibObject
SnmpMibObject
------------------------ cut
which is wrong.

Hi all,

I need help with option 122. I've been browsing forums for days before I run into this obstacle. It is very hard for me to figure out what is a problem for my MTAs.

Hardware I use is BSR1000, modems are SBV5121, server is fedora, dhcp is isc-dhcpd-4.0.0.

I have gradually worked my way through dhcpd.conf - I managed to boot up CM, assign it fixed IP address, and send it option 122 so it wakes MTA up. Problem is that MTA keeps sending dhcp discover but it seems not to "hear" my dhcp offers from the server.

here goes some of the debug info from the CMTS:
