Hi everyone...

I am buying a Cisco ubr7246vxr and I need what is the best ios choise. I have in mind the 12.3(13a)BC6 that i have running on a ubr7223, but I like to know if there is a better ios that you have running.

The CMTS comes with 2 mc16u and the npe-400.

Were can i find a cmts IOS list? or ubr7200 ios support?

Thanks!

Hello all,

I need buy a CMTS to upgrade my old UBR7223 with 2 MC16C cards, I was thinking on the UBR7246VXR, but I really dont know the porpuse of the upconverter on the MC28U card. I have the possibility of buy MC28C too, but if the upconverter is a good idea i will buy that.

Can anyone teach me the differences and the adventages of the upconverter? Or something like MC28C vs MC28U?

Thanks by advance.

Hello everyone. I'm a bit confused about the IPv6 feature of docsis 3.0. If someone has the topic clear, please could you answer some questions.

One thing that is not clear to me if it is possible still possible to leave cable modem provisioning in IPv4 and assign IPv6 addresses only to subscribers' CPEs?

Another question that bothers me. If there we've got a docsis 3.0 cmts and a docsis 2.0 cable modem, would it be possible to assign an IPv6 address to a CPE behind that docsis 2.0 cable modem?

Hello,

I have a problem with EPC3010 modem (firmware dated 10-09-01) that I can not log on to the UBR in DOCSIS 3.0. This is the only type of modem (D3.0) that I have. Modem logs on to DOCSIS 2.0. What option should I activate in the UBR (or maybe cable modem) to run in newest standard?

Here is part of my configuration for downstream:

controller Integrated-Cable 3/0
rf-channel 0 cable downstream channel-id 1
rf-channel 0 frequency 562000000 annex A modulation 256qam interleave 12
rf-channel 0 rf-power 44.0
no rf-channel 0 rf-shutdown

Hi all,

Hello everybody,

I'm trying to build a config file which open a UGS sevice flow for soft phones.
As we know the UGS service flow is being opened by the MTA part of the CM and is not a part of the Docsis config file.
By know I can make the call only over the BE service flow which serves the HSD service.
can anyone help with an idea, how can I enforce the CMTS to open a UGS service flow via the config file?

Thanks in advance,
Asaf

Hello,

I have a strange problem. Often, some modems stays too long in init (t) state. The logs can be found that the discovery came a package that was sent to offer.

Also, often the CPE of these modems after the successful initialization have disabled network connection, so users must manually turn on connection, after which the address is given.

Has anyone had a similar problem, and can you give me some help?

P.S. Cisco CMTS ubr7200, DHCP server dhcpd 3.1.1 on Linux

Sorry for my bad english.

Best regards!

Hi all,

I'm going to start work on the captive portal portion of my software for private cable operators. I'm looking for comments or feature requests. I'd like to find a way for it to look at the subscriber's cm mac address and allow anything connected to it to pass through if they are already in our database. Using the CPE info just begs the question, "What if they get a new computer or router?" I don't want to pay some to answer the phone and enter a new mac address. I'll make the software do the work.
