similar to: dahdi_monitor doesn't show data on RX & TX: broken card or cable?

Hello, I need to convert the dahdi_monitor output to dBm0, so I can measure Echo Return Loss in dB. I've read a formula that calculate S(k) in ITU-T G.168 recommendation, where S(k) is the signal level in dBm0. Can I use this formula to convert it? If yes, what value should I use to the number of samples if I want to convert a single output from dahdi_monitor? -- Thanks in advance, Gustavo

Hi, I'm experiencing some strange problems with out Digium card. First the details abount hardware and software: Digium, Inc. Wildcard B410 quad-BRI card (rev 01) Asterisk 1.6.0.20 dahdi-linux-complete-2.2.1-rc2+2.2.1-rc2 libpri-1.4.10.2.tar.gz The problem now is that there are a number of clients that I call and suddenly the connection drops. Just a few seconds later the clients calls

I am studying about echo cancellation in asterisk and I want to use the numeric information from dahdi_monitor verbose for my research. Unfortunately, I couldn't find anything about the unit of measurement used in this tool. Which unit is used to measure the signal level? -------------- next part -------------- An HTML attachment was scrubbed... URL:

hi group , i am working on dahdi_monitor for measuring voice quality , so i want to know that on which data i can tell that this PRI lines are working properly, is there any measurement on basis of that i can make MOS. i am working from last 2-3 days but i only get idea about making .raw file and making .wav file and visulal mode of RX and TX of PRI line. what i want is measurement of voice

Hi everybody, In an Asterisk 1.6.0.5, dahdi-linux-2.1.0.4, dahdi-tools-2.1.0.2, with a Digium B410P and an OpenVox A400E, I can't make "dahdi_scan" to recognize the OpenVox. This card was working correctly but suddenly stopped working and I cannot make it work again. Both ?lspci? and ?dahdi_hardware? detect it but ?dahdi_scan? not and I cannot use it. >lsppci: *0a:00.0

Now that I have a new card and my echo problems are 'mostly' solved, I have another major issue to deal with. After about an hour or so the card will stop detecting DTMF tones on incoming calls. dahdi_monitor shows the following: [root at asterisk wctdm24xxp]# dahdi_monitor 1 -v Visual Audio Levels. -------------------- Use chan_dahdi.conf file to adjust the gains if needed.

Dear all, I know this is more a Digium hardware than an Asterisk issue. Already posted a question at Digium, however also like to see whether anyone in the Asterisk community has encountered the following situation: I installed a Digium B410P BRI PCI card on my new asterisk server, following the steps specified in the manual. I can see the PCI card is available using the lspci command: ...

Hi everybody, I have a 1.6.0.5 asterisk system and I?m having many problems with my pstn cards. This system has a Digium B410P with 4 BRIs configured, and an OpenVox A400E. The issue is that it?s impossible to make the system recognize the A400E, despite the ?lspci? output is: 0a:00.0 Network controller: Tiger Jet Network Inc.

Hi, I'm using revision 6822 of Dahdi Tools. # dahdi_hardware pci:0000:05:06.0 wcb4xxp+ d161:b410 Digium Wildcard B410P # asterisk -rx "dahdi show version" DAHDI Version: 2.2.0.2 Echo Canceller: OSLEC # cat /etc/dahdi/genconf_parameters ... pri_termtype SPAN/1 TE SPAN/2 TE SPAN/3 NT SPAN/4 NT #

A previous issue has popped up and once again I'm out of ideas. During the evenings it seems that the TDM channels will spike (dahdi_monitor) and will refuse to listen for audio of any type, this includes DTMF. The only resolution I know of is to stop Asterisk and restart the dahdi service, but that's not a solution. All channels look like this, even the FXS. [root at asterisk Hardware]#

Do anyone knows abount European resellers of these products: * Digium Wildcard TE410P * CarrierAccess Adit 600 Preferably in Sweden, but Europe is also better. Have anyone within EU ordered products from these companies directly from the US? In that case, how is the service and delivery? Thanks, folks!

Hello , I do not know anything abount Ubunto, but I found a Portable Ubunto for Windows and since so many people prefer Linux to Windows I decided to give it a try. It runs very nicely, so I tried to load R, following Instructions in CRAN I added the line deb http://probability.ca/cran/bin/linux/ubuntu hardy/ to /etc/apt/sources.list and then from a console I did sudo apt-get update sudo apt-get

Hi, On one of our servers, we're having problems with incoming faxes. The connections come in through a PRI into a Digium TE820 card.

Hi everyone! I'm using Ubuntu Dapper and today i build an individual kernel based on the vanilla sources for 2.6.16 with the CK Patchset. Everything works fine, except wine. Everytime i start an application with wine or just winecfg it needs a long time to come up. Winecfg e.g. needs about 2 minutes (with the default Ubuntu kernel abount 10s). During that wait time i can hear some

Hi, My asterisk server was working with a 4-FXO analog card (TDM400P). I recently added two digital cards: a TE120P (1 PRI) and a B410P (4 BRI). The B410P is still unconfigured but inserted in a PCI slot. The TE120P's jumper is set to E1 as it will connect to a commercial PBX's PRI card also configured as E1. My analog channels used to be 1-4 but since I added the new cards I changed
