Docsis chat

Hi,

Has anyone out there ever been successful in getting an ARRIS C3 to use an external Linux DHCP/TFTP server? I've dome it with 1000'a and 1500's, but am having a heck of a time with the C3. I have the DHCP DISCOVER, OFFER, REQUEST and AC working, but the TFTP won't work. It's not an IP routing issue and not a file security issue. Any ideas?

Hi,

I am trying to configure cable modem environment for some testing purposes. I have following hardware:
Motorola BSR1000 CMTS
Arris Touchstone Telephony Modem TM501A
Incognito Management Console
Docsis 1.1

The problem that I am facing is that MTA is not sending DTMF digits over RTP (inband).

Hello,
My goal is to increase bandwidth availabe to users from certain time of day (for example to increase transfer from midnight). Afaik its possible to achieve this thing without the need to reset cable modems by creating additional service flow with increased MaxRateSustained parameter. However i do not know how to make the transition from normal traffic flow during the day to the increased one. Do i need special classifier or is it done on CMTS? I have Arris C3 CMTS and for provisioning ISC DHCP, TFTP Server on Debian. Thanks in advance for help and sorry for my english.

Regards

Hello,

how can i set a Quality of Service(QoS) policy to preserve the voip traffic on my docsis network?

I have a Motorola BSR2000 CMTS, Cable Modems Motorola SB4200, and for provisioning ISC DHCP, TFTP Server on Centos 5.2...

thanks in advanced...

Hello All,

I'm setting up a C3 with a Debian linux server and its dhcp server. I have cable modems on the C3 that will not get past the init(o) state. I believe that means that the cm cannot get a config file from the tftp server. my syslog shows this:

Jul 20 11:33:47 benchmark dhcpd: DHCPDISCOVER from 00:0a:73:f6:d8:77 via 10.5.1.2
Jul 20 11:33:48 benchmark dhcpd: DHCPOFFER on 10.5.1.4 to 00:0a:73:f6:d8:77 via 10.5.1.2
Jul 20 11:33:50 benchmark dhcpd: DHCPREQUEST for 10.5.1.4 (10.1.1.1) from 00:0a:73:f6:d8:77 via 10.5.1.2

I am new to this Docsis technology and my company wants to inject internet and voip in CATV. I therefore need a small CMTS for testing before spending tens of thousands of dollars on the larger one that will supply atleast 20000 clients. So, can someone advise me where to get a cheap CMTS for my tests. Thanks to all.

Does anyone have any type of comparison data on all the DOCSIS provisioning systems? I cannot find anything in Gartner or Forrester. Any help would be greatly appreciated.

Hi, everyone

I'm seeing a whole lot of these messages in dhcp log for varios cable modems:

Jul 15 09:28:11 mynetwork dhcpd: DHCPREQUEST for 10.67.4.17 from 00:13:11:a6:96:0f via eth2
Jul 15 09:28:11 mynetwork dhcpd: DHCPACK on 10.67.4.17 to 00:13:11:a6:96:0f via eth2
Jul 15 09:28:11 10.67.4.17 CABLEMODEM[DOCSIS]:<68010100>DHCP RENEW sent - No response

It looks like DHCPACK from the dhcp server doesn't arrive on time or doesn't arrive at all. The strange thing is that when I ping the cable modem, there is no packet loss. Neither latency is high.
