RFGW 10 Questions

Does the RFGW 10 require any type of data license like the RFGW 1? Are there any major gotchas with a used RFWG 10?

Thanks.

Yes, you need Downstream QAM

Yes, you need Downstream QAM licenses. The number per line card varies based on how many downstream channels you are configured for on a service group. No major issues besides some funky stuff happening with the DTI modules which was corrected in the a newer code.

Clarification

I understand that the DS384 cards can be licensed with different amounts of channels. 64, 128, etc. I'm trying to figure out if there is some type of license required to use those channels as data qams vs video qams. For example, the RFGW 1 with 48 channels needs 1 data license in order to use the qams for data with the DTI server. The 96 channels RFGW1 needs 2 of those data licenses. I haven't found anything about data licenses for the RFGW 10 so I'm wondering (hoping really) that the data licenses are not a thing on the RFGW 10.

Thanks!

Harmonic NSG9000-40G is

Harmonic NSG9000-40G is another popular edgeqam.

Up to 18 RF ports. Each port has up to 36 DS channels (648 DS total).

One or two of these gives you pretty decent capacity, while taking much less rack space than RF gateway 10.

Harmonic

Thank you for the suggestion. Do you know what licenses are required for the 40g or possibly the 6g as well? I'm trying to figure out what 2nd hand options are actually available/viable for the 3g60-eqam combo.

The NSG9000-40G does not

The NSG9000-40G does not enforce licenses, it just displays a warning that the license server is not found.

If you bought a used NSG9000-40G with 9 x RF cards (18 RF ports), it will most likely show 648 QAM license and 0 DOCSIS license.

You can fire up your CMTS and test everything out.

And then later if all working well and you are putting device into production, you should go buy the DOCSIS licenses (1 per active DS channel)

Also note that you need to

Also note, to run an edgeqam you need to have :

* a DTI server (eg TimeCreator 1000)
* 2 x DTCC cards in your CMTS.

And if you have more than a couple of 3G60 cards, you will need an aggregation switch. Takes the 1G links from 3G60 cards / SPA24's, uplinks to the edgeqam at 10G.

TC1000

Is the TC1000 the only DTI server that is available? It's the only one I've ever seen mentioned. Just wondering if there were other options or if that's the only one.

Thanks again.

Edited because I can't spell.

I have bought TONS from that seller on and off eBay and would buy from them, especially at that price.

TC1000

Yes I've noticed they have gotten much cheaper recently and I've purchased a couple already. I was just wondering if there was another version out there in case these start dying off en mass. The TC1000 appears to be all we have.

There are only DS licenses

The RFGW-10 is much easier to license but a bit more time consuming to setup than the RFGW-1. It only requires Downstream licenses on the DS384s cards and does not require 2 Data and 1 Octal on the main board like the RFGW-1.
Only thing Id say to remember is to not underestimate the power requirements. You'll need at least 40A DC to power it and two power inputs to one PEM, which can be achieved with a Y-type cable jumper from a single rectifier.

RFGW-10

Thank you for clearing that up and for the heads up on the power. I'll keep this as an option but the Harmonic looks more suitable if I can find one.

* TXO Systems

Thank you. I'll call/email

Thank you. I'll call/email those folks. My usual ebay scouring hasn't turned up much.

I do wonder if these 2 together would work?

I don't recommend the NSG9000

I don't recommend the NSG9000-6G model, unless you tiny ISP.
And in that case you should buy the 20x20 linecards rather than 3G60.

The suppliers I mentioned have fully populated NSG9000-40Gs available.

NSG9000-40G has 9 x RF card slots.
If you need to save some $, perhaps buy the 40G unit but with less of the RF cards.
Then you still have the safety of being able to expand the capacity later.
