I have BSR 64000 installed & have 10.60.128.0/22 pool (approx 8000 IP) for inside internet users. I have Cisco Router 3845 with 256 MB memory where i do NAT with Public IP (i have pool of /24 - 256 Public IPs). Unfortunately Cisco Router memory gets overused & 3845 Router hangs. Can i shift NAT on my BSR 64000 & terminate ISP on BSR GigE port directly ?
Pl guide how to do NAT directly on BSR 64000.

We are a small ISP providing internet over our cable network. actualy we give the provisioning an system management to an external company. Our problem is that we do not have access to any tool from that company. We whant to take control over our network and we need help to start.
Here is what we have:
=>Cisco uBR7223
=>Cisco uBR7200
Here is what we need.
=>Tool for provisioning our customer
=>Tool to mesure trafic and calculate exeded traffic of customer for invoicing

Is a kerberos server absolutely necessary in a DOCSIS1.1/PacketCable/VoIP deployment using a CM/MTA like an Arris? What does it do for you? Is there someting (pdf/doc) that explains it's use?

Is there any way to obtain a measurement of the downstream BER or MER with a cable modem, without using a QAM analyzer/tester?

The Cisco uBR900s are reporting always 0, and they say in the docs it does not report this value. Are there any SNMP MIBS for obtaining pre/post-FEC error rates?

Hi all,

as many of you here before I am also having some problems with getting eMTA to work. I can successfully get the CM part working (I am using docsis utility to generate it), but I have some problems getting the MTA part to start.

I have the following option 122 suboptions:

for CM:
option docsis-mta.dhcp-server-1 xxx.xxx.xxx.xxx;

for MTA:
option docsis-mta.provision-server 0 "\003mta\007domains\003net\000";
option docsis-mta.krb-realm-name "\005BASIC\0011\000";

Hello,

I'm looking to buy a lot of 100 or 200 DOCSIS 2.0 used cable modems. A plus is if they have wireless routers built-in.

Contact me at root at net1 dot cc A.S.A.P.

Kind regards,

HI,

Recently we installed new BSR2000 in our network and i noticed that it uses about 3mbps traffic only on the downstream even if the downstream port is not wired anywhere and there is no modem on the BSR. Is this behaviour normal or there is some we need to do?

thanks

Hello,

I've done this many times on the Arris 1000 and 1500's, but do I turn on SNMP in the C3 so I can do some basic SNMP stuff? For example, I use Linus and PHP to run this code:

$modemNumber=1;

while(@snmpget($cmtsIP,"public",$cmtsModemPrefix.$modemOID.$modemNumber))
{
echo snmpget($cmtsIP,"public",$cmtsModemPrefix.$modemOID.$modemNumber);

$modemNumber++;
}

When I try the above I get:

Warning: snmpget() [function.snmpget]: Error in packet: (noSuchName) There is no such variable name in this MIB.

I'm installing internet access to an older cable tv system. The Arris CMTS 1000 and a few modems are winging their way here now. The more I read about setting up this equipment the more I get confused. Just how many PCs do I need?
Is there any DOES-ALL Freeware packages I can use to keep the PC count down to one PC? (I'll be wanting to use Linux). Docsis_server just does 'provisioning'? Nagios just does 'monitoring'?

Can the two servers run from the same PC?

Hello Dear All,
Please, please help me with the TWG850 Provisioning.

Provisioning - means that I have some server and TWG850 which is connected to this server. And I want to configure some network or TWG850 for this device, etc..

also from Thomson docs: Provisioning - The process of enabling the Media Terminal Adapter (MTA) to register and
provide services over the network.

Anybody can describe step-by-step how I can configure auto provisioning for TWG850.
Or can give me some necessary URLs.
Thank you a lot.
