How to provision Motorola SBV5122 and Thompson DWG850-4B for Sip Asterisk?

Forums: 

Hello everybody !
First of all, I would like to apologize for my English (I use Google Translate).
I will try to be straightforward not to take too long from you.
I have 2 cable modem bought in a batch of scraps but working, 1 Motorola Surfboard SBV5122 and 1 Thompson DWG850-4B and a DHCP server with asterisk and 2 SIP accounts I configured.
I would like to enjoy these two cable modem and use them here at home in the asterisk server SIP accounts I have. (The Asterisk server does not have internet access, only intranet)

Casa packet capture

Forums: 

Trying to debug an issue with a misbehaving cable modem on a C40g.
I'm using the 'mirror cm' command together with tcpdump and it's generating a packet capture, however I'm stuck at the following step:

"On the TFTP server, run the ccap command (./ccap test.out) to create a file called out.cap. Use FTP to transfer this file to a PC running Wireshark (or equivalent program). Change the Wireshark settings by editing preferences and Protocols: Frame by checking off the “Treat all frames as DOCSIS frames” box. Wireshark will decode the DOCSIS control packets."

mini-slot utilization

Forums: 

I'm seeing high utilization on a specific node, with not a lot of subscribers (88), using ATDMA, QAM64, 4 mini-slots, any recommendations on how I can lower this? Not sure what's causing it, could it be a user? Have 6 upstreams and they are all constantly over 90% and I have reports from time to time of voice problems in the upstream direction.

DHCP - Docsis

Forums: 

Hi

I currently use a software that I develop in php to edit the dhcpd.conf file, after I make a change I have to restart for the changes to be applied, also only one person can use it, because if two people, for example, coincide editing or doing a registration of a new user can cause an error in the correct writing of all the information in the dhcpd.conf file.

What alternative can I use to solve this, to have a dhcp that several people can manipulate at the same time, to edit, register, change plans, without any problem.

regards
