It could be the DSP driver, or it could be anything else (e.g., flash issues). If you want to know whether the real problem is the DSP driver or not, then change the DSP driver to "dsp70A" and reboot. If it connects, then that is clearly not the problem.

The stray adam2 variables should not cause any problem - but they are taking up valuable environment space. You can just run

Code: Select all

unsetenv autoload
unsetenv autoload_timeout

No need now to change the DSP driver, using the 4mb-flash image worked beautifully :). I removed those environment variables via Telnet :).

I don't really care who has my IP address, drats ISP won't give me a Static one :(. Thanks for thinking of that though :)

Hi,
i just upgraded to new version 2.95. No problems at all and everything is working as expected :D
But i think i found a bug :shock:
In Status -> Modem Status -> Path Mode is displayed as Interleaved but it should be Fastpath !
All of my other modems are displaying this correct. And the ping times confirm that Fastpath is active.
So i think this is a bug.

You know I think you have reported this before with the Annex B driver... can happen if the Tiatm and dsp drivers not exactly the same version

Can you check the output of

Code: Select all

 cat /proc/avalanche/avsar_modem_stats
which is probably the source of the information on that web page, I am definitely interleave (Annex A) and error counts confirm it.

Code: Select all

        [Downstream (RX) Interleave path]

I also get this,

Code: Select all

Trained Path:           1
so guess that says interleave - incorrectly in your case it appears

What exact versions of atm and dsp do you get reported?

Code: Select all

/var # cat /proc/avalanche/avsar_ver
ATM Driver version:[7.05.01.00]
DSL HAL version: [7.05.01.00]
DSP Datapump version: [7.05.01.00] Annex A
SAR HAL version: [01.07.2c]
PDSP Firmware version:[0.54]
Chipset ID: [7300/7300A]

These are older respectively lower version number than original manufacturer firmware.
With original firmware the path mode is displayed correctly. They use Version 7.5

Yes we know about the Sphairon 7.5 - its also now in OpenWrt! Unfortunately the 2MB flash firmware can only contain one set of ATM/DSP, and I think we have used 7.5 in the past but latest is not the best for all - hence the current 7.0 selection.

is there any roadmap for the future release ie 2.96?

Will there be a newer dsp driver or any cool dsl tweak features?

Which router is this on? Sounds like you're running a "Lite" version of the firmware.

No. Features come as needed or requested - and bug fixes come as and when reported/discovered and we know how to fix them.
sandman06 wrote:Will there be a newer dsp driver
There is no newer dsp than 7.5 that I know of.
sandman06 wrote:or any cool dsl tweak features?
If you mean low-level tweaking of DSL parameters, the answer is that you already have as many as you could want (with the DSL_FEATURE_CNTL*) variables - as long as you know what to do with them. There are tools that can make it easier to manipulate them - but such low-level activities are only for the brave.

I don't think that it is something that we can fix. It is the result of a core logic query, which you can run on the command line like this

Code: Select all

echo "sar:status/dsl_pathmode" | cm_cli_ex
A return value of 0 means Fastpath, and 1 means Interleaved. I assume that the real response comes from the tiatm driver. If so, we can't do anything about it, since we don't have the source code for that version of the driver.

ok thanks.

When you mentions tools do you mean stats loggers ?

My ISP is bethere(uk), from what i have ready their dslam is a broadcom, is there any disadvantages or advantages of having different chipsets.

I am using D-link 320t, i want to tweak the snr margin value to increase the sync speed.

A nice tool would be a tool scaler, like dgteam firmware . Can this be implemented in routertech ?

Yes - and other tools like it.

Unfortunately, I don't know the answer to that question.

I think the modem drivers are already pretty good at getting the best speed for your line. Tweaking the speed to increase it is just going to lead to instability. As far as I am aware (if your connection speed is less than 8meg) the best tweak you can do is to downgrade your DSP driver to v4.x or 5.x. You would probably get noticeable speed increase, and you might also get a lot of disconnections.

I don't know this tool, but I think that an external specialised tool (like the RSL) is probably more appropriate.

This a Sphairon AR860 -> http://www.sphairon.com/en/products/ads ... ar860.html
And yes i'm running routertech-ar7rd-lite-1port-firmware-20110103 / pspboot on it. Should i try the regular version for 1-port routers ?
