Hi All,

If you get this error on your ARRIS CMTS 1000 or 1500:

EH_event: fatal event: CMTS hardware failure: downstream frequency could not lock

One possible cause is that it's too stinkin' cold in your Head End! I've discovered the hard way that these CMTSs do not work below 59 degrees F. Coincidently, either I do. :) I hope this helps someone. Darn it's cold in Michigan today!!!!

I just started to have modems randomly reset. It does not appear to be a upstream noise problem nor a downstream SN problem.
The only thing in the modem log is:
Unicast Ranging Received Abort Response - Re- initializing MAC
Modems are SB5101.
Anybody have some thoughts as to what could be the problem ?

Hello.

I was wondering if the UBR7246VXR is DOCSIS 2.0 capable with NPE-G1, MC28U's cards and IOS 12.3(17b)BC6 or 12.3(13a)BC6.-

The Cisco data sheet says that is EuroDocsis 2.0 (PAL) capable Im not sure that is docsis 2.0 (NTSC).

Regards and thanks!

Is there a limit on maximum ip address and subnets routed through a cable modem? Assuming the modem is bridged and i am routing to a CPE device behind the cable modem.

Can sombody out here tell me what the current FW release is for this modem?

Presently I have SW_REV: 7.1.95

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
