DOCSIS 3.0 Very High US Latencies (C3200)

Forums: 

We have a Casa C3200 in our lab environment, with 1 modem connected to it (8 DS / 4 US channel bonding). We are sending traffic in both the US and DS directions for testing.

The DS direction seems to pass traffic fine with a latency average of about 4ms (up to around 300Mbps).
However, when sending US traffic the latency average is around 70ms (higher at higher US rates). We get some frames at 100ms+ at around 270Mbps.

SNMP OID for total online cable modems on Cisco 10012 uBR? 7360 ISAM FX-8

Forums: 

I'm not having any luck with my searches, so I'm asking here...

Is there an OID that can be used on a Cisco uBR to retrieve the total number of online cable modem?

How about the same query on a Nokia/Alcatel 7360 ISAM FX-8?

Thank you!

MC3GX60V - adding more than 24 frequencies to leg

Forums: 

I have a site with all D3 modems and have 24 frequencies of 1 cable leg running off the first 24 (controller Modular-Cable 5/1/0) on a MC3GX60V card. I have 3 x 8 bonding groups and all is working without issue. I have them set up under interface Cable 5/1/0 as you can see below. I wish to add another group of 8 to the same leg of cable and need to know how to go about doing this. If I put "downstream Modular-Cable 5/1/1 rf-channel 0-7" under "interface Cable5/1/0", then I can't figure out how to create the 8x bonding groups.

APEX 1500

Forums: 

Does anyone happen to have the bootp package for a Motorola APEX 1500 ?

I have 2 units. One works great, the other was given the wrong firmware and needs reflashed. The working one is using 2.0.1.
If there is a way to get the files off of the existing working unit, that would be OK too.

Thanks!

Asus CM-32_AC2600 - Stuck in BPI_INIT

Forums: 

Hey guys,

So I am trying activate this new modem on Spectrum, which IS on their approved list btw. I have now tried two different units and I can't get anywhere with support. I am seeing the two following disturbances in the log files.

Do I need a multicast?

Forums: 

When planning the upgrade, I thought that IPTV in the form of multicast seems no longer necessary for subscribers. A large number of problems with WIFI and routers have led to subscribers using unicast.
It looks like unicast can only be implemented in a simple way-transmission together with data and voice?

Motorola SEM V8 Inital Configuration

Forums: 

Hello, Jimmie Davis here
I work with CATV and Internet that the park provides in a little resident owned community in Florida. We had a V8 throw an Error of Upconverter failure and I am trying to access a spare, but unable to configure due to unknown Ip address which I need to even communicate with the V8. Tried different ideas on how to search for the Ip or trying to Ping the different ones we have on file, but no luck as of yet.
Any ideas from anyone here. Thanks in advance
