Hello,
i'm looking for a way how to check last parameter ds/us of modem in ubr7264VXR.

show cable modem phy - shows only active modems
show cable modem remote-query - shows only parameters of active modems.

i need to know last parameter ds/us of modem when it goes down.

thx for any help.

We have been trying to figure out the best way to control our issues for cable modems. We have switched to the IBBS platform and are discovering issues in our system that we were not aware of. I wanted to get a little prospective on how others out there are using this system.

How are you sweeping your system and what parameters are being used to do so?

How you control your SNR and break up the plant to discover problem areas?

More questions will probably arise as responses start coming in

Thanks!

Hi,

I have 10 pcs of fully loaded CMTS CISCO UBR7246VXR with NPE-G1 and ATDMA MC28U euro/docsis line cards.

These units were purchased as new from Polish Official Cisco Distributor and they worked in our cable network for 1.5 year.

We would like to sell them and we also can offer a delivery + installation (for negotiated fee).

These units are located in Europe/Poland.

Any additional questions please send to grzegorz.gaj(at)gmail.com or grzegorz.gaj(at)smsnet.pl

Hello all

Someone can explain why the dowstream channel or any channel digital, has to be adjusted with at least 5dB less power than the analog channels.

Best Regards

Hi,

I'm currently investigating several methods of monitoring the performance of cable modems.

So far, I've come across
- Broadband forum: TR-069 -> TR-143 (Enabling Network Throughput Performance Tests and Statistical Monitoring)
- Cablelabs: SLED (Software Loopback Application for eDOCSIS)

Unfortunately, besides the official documents there isn't much info out there and I'm wondering if anybody has some
further info on these 'standards' or has also done some investigation?

What is the maximum download/upload of a Docsis 2.0 modem ?
