Hi, I have this problem I´m trying to copy/paste the option file into the /etc/idirect/falcon/ but it only copies a part of it, not all the file, I has stopped the falcon monitor process in order to preven reboots also I can´t ping  or telnet the router from my laptop. Hope you can help me.

1. What version? 

2.   Have you confirmed that your BSP and image are good? 

3. Please talk me thru how you are cutting and pasting. 

4. What are you using Hyperterm?  Teraterm? 

Inability to ping eth0 is naturally due to your opt being corrupt or unusable.

I haven´t confirm that BSPO and image  are good.

Hyperterminal Private edition

Now I cannot gain acces to the router at all, the hyperterm pops a blank screen and the router has the power and status ligths solid green. The hyper says that it is connected but there´s nothing on the screen !!!!


I have a copy of the remote-7_1_1.pkg, cumulative_update-7_1_1.pkg and R73636.opt

Is there a way that I could get the router back to life?

Thanks for your support

Try hyperterm at 4800 8N1 and 9600 8N1.  Hard boot it if necessary, but try it at both speeds (in the event it was used with a GPS device previously).

You are still not able to get on console of that box?  At 4800 or 9600?  IF that is the case it has serious issues.   There is no way to move forward without console access.

If you are not able to get on console,  you will not be able to fix it.  Are you certain that you dont have a bad a cable?  This is a first.  I have never seen someone lose access to console.

Hi

I have been having the exact same problem as YAMA09.

We origionally bought a batch of modems with firmware 8.0.2.5 loaded on and was having problems downgrading to 7.1.1. That is no longer the issue.

I now have the same error :

Fatal Error - Could not open device "/dev/fpga-nx": 2 No such file or directory
Unable to reload layers (tx/rx1)

I have loaded and reloaded the 7.1.1 firmware and have been successful in this process. The same goes for the option file. What makes me think that the option file is ok from my provider is that I used an option from another modem and edited it in notepad making sure the modem number and like were all the same. Also, if there is a problem with the option, it might report the unit of not being a "boot".

I have been emailing tac support and they suggested running the following in the /dev folder:

mkdir fpga-nx
chmod 440 fpga-nx

This then changes the error to:

Fatal Error - Could not open device "/dev/fpga-nx": 21 Is a directory.

Any help will be greatly appreciated!!

Regards
GZ

For clarity:

1.  Does Falcon start?  If so, can you telnet to the process?  I am thinking you are not able to.

2.  How are you able to confirm that the bsp and software packages installed properly?  When you installed those packages, how did you negotiate it?  Manual load with WinSCP or did you use iSite TFTP?


I recommend against editing opt's (too much room for error in that config file).  How are you punching that opt into the box?  CAT'ing it in?  At first glance (of that boot up) it appears there is a problem with the software.  Specifically the BSP and/or Pkg.    I am sure you realize that by now and I am stating the obvious.

Thanks for the reply

Falcon does indeed start. The exact same load up sequence is what  YAMA09 posted. I am able to telnet to the remote but instead of the usual modem number in the brackets, it is saying Error Stack. What process are you asking me to telnet to?

The packages say installed successfully in the HyperTerminal and when i go to /usr/sbin and run falcon --version, it comes back saying version 7_1_1. Is that enough? And I used TFTP to load it as i do not have access via WinSCP or PuTTy.

As for the editing opt's, i have made sure i havent left anything else out. And you remember when i said we got a batch of these modems? I am using and editing the same option file for this modem as i have for the ones i have already recovered. I am CATing it yes.

I see what you are saying. It doesnt look good and may result in an RMA.

Any further assistance would be greatly appreciated!

It sounds like your software may be good.  Errorstack is normally indicative of a corrupt or bad options file.   There is probably a problem with that migratory option file you are using.  Did any of the other modems act this way when you loaded that modified opt in them?

No. No problems at all with the others and all the option files came together. Maybe just request a new option? Will let you know how i go with that.

HI,
Is anybody here. I need some helping discussion.

Can you please tell me explanation for  1db power compression for iDirect modem with HUB ?

Set the remote site to transmit in CW mode so you can measure the transmit signal level from the remote site accurately at the hub on a spectrum analyser. Choose a frequency where you are not interfering with anyone. Use a sufficiently narrow resolution bandwith so that the top of the carrier is well clear of the noise floor, so that you get accurate measurements. 20dB (C+N)/N is ideal.

Note the transmit power setting at the remote and the spectrum analyser level, write them down, about halfway down the paper page.

Decrease the remote site power level by 1 dB and repeat the hub spectrum analyser measurement. Repeat this several times.  Write down each pair of measurements, lower down the page.  If you are obviously in the linear portion of the curve then go up in level cautiously.  Keep increasing the remote transmit power setting and you will find that each 1 dB step up at the remote no longer causes a 1 dB step up in the measured signal at the hub.  The BUC is starting to be overloaded and the signal is becoming distorted.

Plot the measurments on graph paper and draw a straight line through the linear part of the curve. Look at the vertical gap between the straight line and the top part of the curve where compression is starting to occur.  Once the spectrum analyser measured level is 1 dB behind the input level into the BUC, you have reached the -1dB gain compression point of the BUC.  Don't go any higher.  Record the remote modem power setting and
make sure the hub never tells the remote to go above this value
during rain, for example.  The normal, clear sky, operating power will typically be about 6 dB below the -1dB compression point.  Set the final clear sky level to give the required Eb/No at the hub as specified in your system design. Hubs may well do this automatically so that all incoming TDMA bursts are at the same level as far as possible..
1
The -1 dB gain compression point is where the black double ended arrow is 1 dB long. In this case the -1 dB compression point is where the transmit power setting is -18 dBm. The actual BUC capability is +4 dBW at its -1dB compression point. This "2 watt" BUC2 is actually able to put out 2.5 watt.

Regarding the remote modem power setting this might be -12 dBm with a cross site cable loss of -6 dB.

If you exceed the -1 dB compression point the power increases slightly further but the signal pulse shape deteriorates and the error rate increases. Also, you start to cause interference to the adjacent frequency customers and damage your BUC with high voltage spikes which may cause gradual deterioraion or sudden failure.

If you are using a higher order modulation method like 8PSK or 16QAM you should operate below the -1 dB compression point, say -1.5 dB or further down, as these modulation methods have high error rate if distorted.

If you are ever faced with a problem where a remote is believed to be transmitting but nothing is being received at the hub, try reducing the remote power in 5 dB steps. If a BUC is grossly overdriven the signal is so distorted it cannot be received at all by the hub TDMA receiver.

If you are transmtting multiple carriers, typically from a teleport hub, you need to operate your BUC or HPA backed off even more so that intermodulation product interference is down at an acceptable level.  Read the BUC/HPA manual about the curve for input and output back off for multicarrier operation. e.g. -4.5 dB input back off. Two equal carriers, would each be at -7.5 dB input back off maximum.

Best regards, Eric.
