Anyone experience with TM-600 VDSL2 testing device
« on: December 12, 2017, 12:34:36 am »
Hi I am currently involved in a VDSL rollout in the caribbean and looking for an affordable VDSL capable field tester. Some known equipment is either very expensive, not capable or not produced any more like the EXFO maxtester/cable shark, Fluke 990 etc.
Main purpose is to be able to test VDSL2 using profile 17a modem emulation including all statistics, TDR measurement and plain impedance/balance properties.
One of the chineese suppliers does deliver an all in one affordable box that seems to meet most of the specs, the TM-600. However no reviews can be found at this time. If someone does have info on this instrument I would appreciate some feedback.

Regards,

Eric

Hello Emo

Since this post, have you been able to acquire the TM600 for VDSL?

If so, what is your opinion on this equipment.

Thanks

Hi securipole,

Yes, I was able to acquire the instrument and used it to verify extensions during a VDSL rollout. It does work OK, detailed results can be recorded(max 100 measurements) and later printed/saved for logging purposes. Also useful as tool to verify customer issues independent from their equipment and limitations on what can be reported. The instrument has also some general tools on board specific for phone lines.
Unfortunately the reporting is rather basic so graphs only in black and white for now( might be improved in the mean time )
The instrument is just a little bigger than a regular DMM so can easily be used in the field. One drawback however is the LCD screen that can be difficult to read in plain sunlight.
It is not top of the line, however very affordable and well capable for its purpose.

Hello everyone , sorry for digging up such a old thread but this was the only info i found online about this instrument .

I got my hands on a  TM600p VDSL tester (model V2.900TOVC) It's (for its price) a good machine that has already helped me quite a bit.
But, as is often the case with Chinese electronics, documentation and support are simply non-existent.

I have read the instruction manual cover to cover many times, but I cannot figure out the following:

  • How to delete saved records: Despite searching extensively through the manual, I can't seem to find any instructions on how to delete saved records from the device. This is crucial for managing storage space and keeping the data organized.
  • PPP not working over an ADSL2 line: I've encountered an issue where PPP (Point-to-Point Protocol) does not seem to work over an ADSL2 line. However, it works perfectly fine on a VDSL2 line. The VLAN used here for VDSL is set and also the VCI/VPI values for ADSL2. Is there a specific configuration or setting that I'm missing to enable PPP over ADSL2?
  • Can the device make a PPP dial from its Ethernet port? This would be a life saver when dealing with FTTP ONTs ,The seller mentioned that it's possible for the device to make a PPP dial from its Ethernet port, but I can't seem to find any information on how to do this in the manual. If this feature exists, it would greatly enhance the flexibility and functionality of the device for my needs.
  • When in Telephone dial mode, the device immediately plays the dtmf  tone , dials the numbers entered, Is there a way to completely input the number , and then press a button for the device to send
    in  one shot the DTMF tones, allowing for better control and troubleshooting?
  • Does the device, when in "modem" mode, operate as a transperant DSL-to-Ethernet bridge? I want to know if the device, when set to "modem" mode, functions solely as a bridge, essentially acting as a modem and passing the DSL line directly through to the Ethernet port for connecting other tools to diagnose higher OSI problems . Also , if i exit to for example back to the line menu to check for line errors (fec sec crc) will this bridge still be operational ?

Any assistance or insights you can provide on these issues would be greatly appreciated. Thank you in advance for your help!

Best regards

I used this instrument during the commissioning of several DSL networks. On arrival the instrument could not create printable reports. After notifying the supplier, TMTools, a firmware fix was sent to me. They responded very quick. I received v1.032 that resolved the issue. Some small bugs still remained however.
I did both ADSL as well as VDSL(17). The modem unit inside is made by Broadcom

If you have VDSL2 you should have ADSL2 . For me it has worked in a ADSL2 AnnexB line.
You can check this at SysSet->xDSLmode->XDSL MODE SET

Intresting .

Indeed the UI of the instrument is Clunky & has bugs. Also the vendor (TmTools ) has fantastic support for a chinese based company where most of the times wont get any support! .
I sent them the questions i asked here (at #3) and they responed fearly quicly and relatively to the point . For example the first question "how to delete reccords" they sent me a video showcasing that to delete a record , you open it and push or hold the # key and its gone! Something to note when i did this it wiped my whole tester , all the reccords , settings etc !
