ZyXEL VMG1312-B10A - first look
« on: May 12, 2018, 12:51:55 AM »

I just tried mine out for the first time, in modem-only mode. Just plugged it into the wall socket and it got auto-configured by AA using TR-069. Its wireless went off, thank goodness, and it became a straight modem without me having to touch it.

I can't believe how fast it is. I'm getting downstream sync rate of 3.11 Mbps sync rate instead of 2.75-2.80 Mbps with the DLinks, and at a very slightly higher actual SNRM, currently 2.9dB downstream whereas with the DLinks the downstream SNRM would often be a lot lower at 0.6-1.5dB.

Upstream is rather slower at 519k instead of 566k. It is currently plugged in to line cwcc@a.1 instead of the DLink DSL-320B-Z1 modem that was reporting HEC errors, possibly bogus, woe detailed in another thread. The upstream data rate of line cwcc@a.1 has always been very high compared to the other two lines, ~100k higher than line cwcc@a.3 and ~60k higher than line cwcc@a.4 so it will be interesting to see how the other lines perform with the new modem.

Q: I don't know how AA’s TR-069 behaves, what it will actually do. Could anyone help me understand it? I can read the spec of course but that's not all that I'm after here.

I see that I can do various sorts of remote config via AA’s clueless.aa.net.uk control server. It says somewhere that you can remotely update the firmware as well and I think monitor the modem.

I'm worried about what will happen to any config changes I have made on the modem itself. Could anyone help here?

I immediately changed PPPoEoA RFC 2684 option from LLC to VC-MUX to save 8 bytes of overhead, not that it makes any difference at all on 1492 or 1500 byte long IP PDUs as they are still 32 ATM cells in length, but on small packets it can make a huge difference when that 8 byte saving saves an entire cell. Perhaps AA is using LLC to be safe on 20CN which won't work with RFC 2684 VC-MUX. They should have an option in clueless to change that amongst the remote modem config options. If it is there I haven't noticed it yet.

In fact, I don't know where some of the detailed config comes from and I can't see that many settings in clueless related to these minutiae.

I'm hoping it is using no-FCS option in RFC2684? Could anyone tell me what BT 21CN does or what this modem does in this respect.

I also tried out the Burakkucat theorem and changed from auto mode to G.992.3-only. The downstream sync speed went down by ~20k. I will repeat this test a few times to get a better preliminary idea. The Burakkucat conditions definitely hold, as this line is still a lot slower than Mr Cat’s even with the current speed up, so it should be a reasonable candidate.

A few quick comments . . .

Currently it is operating in non-baby-jumbo-frames mode. Once the firmware has been updated to allow the larger MTU, I would no longer use A&A's TR-069 server. I would go as far as clearing ROM-D to purge it of all A&A's modifications.

I had to download RFC2684 and quickly scan it for any mention of either "non-FCS" or "FCS". I only found occurrences of the latter. The first mention occurs in "Section 5.2. LLC Encapsulation for Bridged Protocols" --

Quote
In LLC Encapsulation, bridged PDUs are encapsulated by identifying
the type of the bridged media in the SNAP header. The presence of
the SNAP header MUST be indicated by the LLC header value 0xAA-AA-03.
The OUI value in the SNAP header MUST be the 802.1 organization code
0x00-80-C2. The type of the bridged media MUST be specified by the
two octet PID. The PID MUST also indicate whether the original Frame
Check Sequence (FCS) is preserved within the bridged PDU. Appendix B
provides a list of media type (PID) values that can be used in ATM
encapsulation.

Having read that, I need to ask is the modem configured in LLC or VCMUX mode?

It's in VC-MUX mode. As I have probably said earlier, saves 8 bytes of RFC2684 overhead in PPPoEoA, which either counts for nothing, as for 1492-1500 byte IP PDUs, or a saving of a whole 53 byte ATM cell if 8 bytes less AAL5 payload will make the difference, could be huge improvement on short PDUs.

I seem to remember dimly that non-FCS was the default or most commonly found option, but I can’t remember quite where I read someone claiming this. It could have been here - Farnz’ blog perhaps. Farnz is known on the AA public IRC channel and is very helpful. No FCS is the sane option, not that that means much. Both are fine anyway within the 32 cells limit for 1492 byte IP PDUs.

You are quite right about TR-069. I wasn't thinking straight, I can't have them accidentally wiping out the good modified firmware by pushing out a new firmware release on top of it. It's a shame though, as I would like AA to be able to do remote monitoring / diagnosis if they should need to.

Ideally I would give them my XML modem config let them keep it in the system for me if that's possible, don't know how it's done exactly, it just says you can ‘edit it’ but I don't know exactly what that means. Then ask them nicely if they would check and adopt that mod, build it themselves and distribute it as an official AA release since they have been so desperate for MTU 1508 baby jumbo support anyway. So they could push it out, others could benefit, and I would not necessarily have to scrap TR-069.

Could someone maybe help me kill TR-069?

btw what is "net attainable data rate" really? it says 3.368Mbps downstream 0.427Mbps upstream. I hear what eg Kitz is saying, so considering the definitions that I have seen these numbers are odd because attainable upstream 0.427Mbps is clearly wrong as it is currently running at 0.515Mbps upstream, so it says, right now.

Are these numbers from BT, that are obtained somehow and are maybe insane? They are explainable as just out of date, as the downstream number is not old, and the upstream has never been right, the upstream reality has never been as low as that, in fact the upstream has been rather higher on line 1 with the DLink modems at 0.566Mbps than the current value.

Edit: I've found the supervisor password on v14 by using "dumpmdm" in telnet ;D. I right clicked a command prompt's window title bar, went to Properties, Layout, and set the Screen Buffer Size height to 9999, then once I sent dumpmdm in telnet I right clicked, Select All, pressed Enter to copy, pasted in Notepad and searched for "supervisor", and below that line was the password. So, the only thing on my v14 is that it's not the default password.*
* Keep in mind, it might be accessible because I'm using v11 config and I hadn't reset it when i upgraded to v14 ;) - screenshot attached
This certainly would be the best course of action for anyone that's able to find the supervisor password using dumpmdm (although, half the time clearing the ROM-D in telnet with the admin account is sufficient, and it probably depends on which ISP the unit is from). Clearing ROM-D in the GUI, pushing the reset button with a paper clip until the lights went out, and done. Remember to not restore any configurations from before the clear.
PS. I'm unable to verify it had been cleared on my device using the supervisor Busybox shell, and on admin account both "echo && bash" and "sh" didn't start it. This is probably due to v14 (I have faith v11 works). There should however be visible signs it had been cleared by looking at the GUI, like the TR-069 menu showing up and ZyXEL defaults.
------------------------------------------------------------------------------
Note: the instructions I've written at the bottom of this post are simpler but less certain to work, see: https://forum.kitz.co.uk/index.php/topic,20495.msg357916.html#msg357916
Quote
(about the "certain method", it's using the supervisor account, and AAJZ.14 might have the supervisor account disabled just like v13 did. However I had used an older firmware, v11, since July 2017 up to a week ago. It's solid, and certainly has the supervisor account enabled (everyone praise v11 for this). The user and password will most likely be different from "supervisor - zyad1234" but there are posts on kitz on how to find it, like this one. If your attempts to gain access to the supervisor account failed, you can flash to AAJZ.11, reset the router with a paper clip and login to the web interface with the supervisor account. There should be a clear ROM-D tab under the Maintenance>Configuration menu. Or you use telnet to send "save_default clean". Afterwards you reset using the reset button and then put the custom v14 back)
* If the firmware tab can't be found in the web interface, or you cannot obtain the admin password, see: https://forum.kitz.co.uk/index.php/topic,19975.msg350589.html#msg350589

Using the admin account to clear ROM-D: https://forum.kitz.co.uk/index.php/topic,19022.msg339500.html#msg339500
Firstly, before following the steps, backup your current configuration in the web interface, then power it down and disconnect the DSL cable, and then start from step 3, unless you lack access to the admin account, then reset the router using a paper clip or somehow find the password.
Once finished with the last step, verify the ROM-D had been cleared (I am currently running the same custom v14 as you and cannot enter Busybox with admin account: in the quote above I've explained this is attributed to v14), configure it from scratch, and once you're done with all of the configuration, power it down and reconnect the DSL cable, and that should be it.
* The previously backed-up configuration is the same as before the clear, which if successfully cleared allows the router to reset to its firmware config.

If someone has something to fill in or correct feel free as I'm not an expert on instructions, and I'm here for a quick answer  :fingers:

From the stats visible in telnet I can now see the G.992.3 basic framing parameters and some of the detailed counters. One thing that is odd is that I have low value of D=2 downstream (D=8 upstream). I don't know why this is. I rechecked the settings in clueless and BT 21CN interleaved downstream setting is 'on' as opposed to 'medium' and I take it that 'on' ought to be greater than medium?

Looing back at old info, Burakkucat has a D=32 for example, far safer than me.


* Another thing, I see some interesting looking counters that mention a fair number of 'rexmt' (retx?) events on the downstream ! Is this G.992-supported standard G.INP (G.998.4) mechanism at work! Wow, if so I didn't know that such was available for mere ADSL2, but this is the latest 21CN MSAN hardware at the NSBFD exchange now, installed at the end of 2015. (Another wild guess is there possibly a Broadcom-proprietary PhyR ReTx mechanism ? We think this is now Broadcom talking to Broadcom at the NSBFD exchange.

* I tried putting some XML comments for my own benefit in the config XML, and it barfed, as the Americans say. Shame, they don't really handle actual XML then.

Thought to post mine too for no reason, but if there's something I can do to improve you can say because I don't know (I had 28-29db and less errors before someone cut our in-building phone wire, this will be gel crimped soon, right now it's twisted).

We've got it all on this thread!

@Weaver with Broadcom PhyR retransmission on ADSL2+ (the stats show different counters for PhyR and G.998.4 / G.INP). Without even the dire warnings of ADSL2+ might be worse on a long line!

As far as the BTWholesale interleaving levels go, I think any higher levels are only available on banded profiles, so "on" and "medium" will be the same. You don't actually set the interleaving depth, you set the minimum INP value (and the maximum delay).

And @spring with G.INP on an ECI cabinet? Although with low speeds and very high SNRMs.

That's how my package is, and cab is 100-150m away.
Well, is it not ECI?
Anyhow, the stats I posted are authentic.

Upstream is rather slower at 519k instead of 566k.
Well, you can see it's the same with the VMG1312-B10A that I have, and generally known among other users on the forum when it comes to VMGxxxx-B10A's. But download usually, although not always, is the weak spot and it gains there when compared to "any other router". Maybe there are cases that the gain on the download can't make up for the loss in upload, but that can happen.

BTW Does it sound like I was right about the meaning of the 'rexmt' counters?

I've looked at the picture of bits per bin. The B10A does better than a DLink (which unfortunately was not on the same line but I don't have the right data at hand) because it does better at the high end where the very highest bins, 131-162, have 1 bit in use on the b10a instead of 0. I don't know if it is down to more signal or less noise at the high end. I'm thinking this might be to do with the analog performance if the B10A. (Vague memory: Did someone say something about it having superior hardware of some such sort, beneficial filtering that is absent on the cheaper 10D?)

The upstream of the B10A is better by 1 bit across the whole of the range but the actual upstream sync rate is slower so the difference is I presume more than cancelled out by a much higher level of FEC but I haven't looked at the data, and I don't have access to that data for the DLink.

It does seem to be a very impressive piece of kit.

I have two more coming, bought from France on eBay this morning.

Well, is it not ECI?

Take a look at the output produced by xdslctl info --vendor and see what it shows for the "ChipSet Vendor Id:" line.

If the (line card) chipset shows as Broadcom, then the cabinet is Huawei equipped. If it shows as Infineon, then the cabinet is ECI equipped.

Weaver could try enabling upstream PhyR on the modem, in case it's switched off for upstream on the modem by default.

My intention wasn't to question the authenticity of spring's stats, yes the vendor is IFTN and G.INP is on the downstream. The stats do like a bit unusual though, they suggest the line should be capable of getting the full 80/20 but it's only connected at about 44.8/3.5. Perhaps it's banded, or it happened to connect at an exceptionally bad time, and conditions later improved.

Elsewhere spring has mentioned his line is "fixed rate" and at the max speed it can be. Not sure which service providers offer 45/3 connections though  ???

Seems a crying shame not to be on an 80/20 package with those stats though.
