Inbound voice Delay

Forums: 

We are currently running a form of DQOS-lite (-KDC server and BPI). We have a Ubr10K, Cedarpoint switch, and end to end QOS with Dynamic service flows created using Moto 5220's. We are currently experiencing an issue where we have delay with incoming calls. on-net to on-net and off-net to on-net. What happens is the person answering the phone says hello a few times before the far end can hear them pick up. The mta user hears a click like the connection establishes then everything is fine.

Docsis-Server problem

Forums: 

Anybody seen a similar error message?

"NAK -- no subnet for ip 10.200.120.67 mac 000c418ee68e vlan 0"

If you have, do you have an inkling of what it means?

Thanks,

PacketCable quality issues

PacketCable

Forums: 

Hi,

I'm trying to implement PacketCable Cable Modems on our cable plants. I'd like to start testing with the SBV4200s. I have a config file editor, but can someone point me in the right direction by either posting and example config file with PacketCable or sending me somewhere for descriptions of all the MIB stuff?

Thanks,
dbs

CM Firmware upgrade

Forums: 

Hello:
I am trying to upgrade the firmware of an SMC8013 modem. I have the cmts setup and making sure that the modem ranges as usual. I can set the docsDevSwServer, docsDevFilename, the docsDecAdminStatus is 'allowProvisioningUpgrade' and docsDevSwOperStatus is 'other'. When I try, nothing seems to happen and I do not see any activity on the TFTP for the filename. Any help from anyone will be greatly appreciated.

Large broadcast domain for docsis customers

Forums: 

Hi everybody.
I`m thinking about the advantages and disadvantages of working several CMTS in routing and bridge mode.
Currently I have 5 Arris C3 CMTS working in bridge mode, all in one VLAN.
Of course CPE traffic separated from CM traffic. Total amount of CPE (and CM accordingle) is nearly 2100. And this all in one VLAN. Such a large broadcast domain confuse me concerning to design and security issues.
Does any body have experience in administering such an environment with large amount of hosts in one VLAN?
