CableLabs root certificate expiring

Forums: 

We will be having our first actual root certificate expiring that is NOT modem vendor related.
I have it set to 'Trusted'

Is there any concerns to this, or am I just trying to raise my blood pressure?

TM9202

Forums: 

Good afternoon everyone!
We just picked up some Arris TM9202 mta's to replace our aging (and non replaceable) Arris 602 mta's.
We are using packetcable 1.5 on the 602's, and would like to use Packetcable 1.5 on the 9202's.
We have the devices showing up as emta, which is what we want.
We are using AB01.06.013_051923_223.PC20.TM.NA.simg firmware, which supports PC1.5/SIP
We've added 'sipEnePntConfigUserId' to the mtaconfig, which means the mta will be provisioned with PC1.5 rather than 2.0.

Omnistar Transmitters

Forums: 

I know this isn't docsis, sorry but this is a bit of a hail mary to industry veterans. I need docs on omnistar transmitters/receivers and older harmonics nodes.. Anyone? I have to do things on the cheap right now as there are overbuild grants coming in that could kill us.

Forums:

Casa OFDMA - Appears OFDMA not being utilized

Forums: 

Running into an oddball issue.
In the head end, a 3.1 modem is hitting 229mb max (test modem). Sometimes.
Out at the node we're getting 70 out of that same modem. We're running 3.2 6.4 6.4 3.2 atdma and ambiguity exclusion on ofdma carriers running 48mhz to 80mhz.
We're only getting return through the atdmas from the looks of it.

Just can't figure out *why*.

uBR-MC88V 8 channel bonding throughput

Forums: 

I have recently set up a small DOCSIS lab, using a uBR7225 with an MC88V card. It is configured in an 8x4 bonding group, and all of my various modems come up just fine. I cannot seem to get any modem to work higher than 100mbps on the downstream, and I am looking for some tuning suggestions. Here are snippets of the configuration:
