Help With Physical Layer
Hello users, I have a Digium Te235 and asterisk 13 which have worked well with 1 carrier but we have failed to add a 2nd carrier. The second telco brings their E1 line over finer, terminated in a RAD modem and they give me ethernet to the E1 card. It's the first time i am having install such a solution, which ideally would be not a big problem. However, The physical layer has failed to

X100M never goes on-hook state
Hi guys, I've been experiencing a very strange issue with my Digium Card TDM400 as of this week. It has two FXS and two FXO. The FXO modules (both of them) never goes on-hook after hanging up in Asterisk. It had worked perfectly well for over four years. I put an ammeter in series with the line and the card, and immediately after plugging the connector to the card, I got 26mA in the circuit

passing opermode to the wcfxs module
Hi, Has anyone in australia got asterisk running on FreeBSD? how would i pass the opermode=AUSTRALIA parameter to the wcfxs.ko module as kldload doesnt let you pass parameters to the module like modprobe in Linux. I tried to get the sysctl variable using sysctl -a it might use but nothing applicable was visible.... i need to set the impedences to 600 ohms, can someone please advice me on

Axes origins and labeling
I have re-labeled tick marks on the x axis. The problem is that by using axes=FALSE, the axes disappears and when they are called back using axis(side=1)..etc. the axis on sides 1 and 2 do not meet at the bottom left corner of the graph. I would also like to have the 3rd and 4th axes in there as well, all meeting in their respective corners. par(mfrow=c(1,2)) gut<-c("Full",

tuning an x100p in Australia for echo cancellation
I have an x100p which suffers from echo (no surprise there apparantly :), and a few of the things I've read about tuning out echo say the first thing to get right is the tx and rx gain, and for that you need a few different types of test lines from the telco (Telstra, Optus, whatever). Does anyone have any numbers in Australia for such lines? I think they just need to send out a tone of a

E100 or TE410 card an PRA line
We are located in Belgium and just ordered a PRA line, the telco asked the following questions : - 120 or 75 ohm ? - Support for CRC4 yes/no ? - B channels in 2 way ? We will buy a digium card but which one should we buy ? could anybody help me with this ?

unit attribute to list elements
Hi, I've started my own (first) package, part of which consists in listing common physical constants (Planck's constant, the speed of light in vacuum, etc). I'm wondering what would be a good way of dealing with pairs of value/unit. > constants <- list( cel = 2.99792458e8 , #m/s > Z0 = 376.730313461, #ohm > eps0 = 8.854187817e-12,#F/m > mu0 = 4*pi*1e-7,#N/A^2

Still unacceptable echo on X101P
I am still having unacceptable echo on my X101P and twidling with the rx/tx gain levels and echo settings appears to have no discernable effect. Some questions for those who may have more significant electrical engineering background than I. 1. This impedance match thing ... will it affect this solution having other phones in parallel with the X101P? This is done so that I can test while not

Crc4 issues
Hi All, This is our 2nd E1 client that we try to use crc4 either with the e100p or with the e405p without luck. After some trials, we ask the telco to switch off crc4 on their side and everything works flawlessly. Is there anything in the crc4 calculation that may be broken? We took a look at wct1xxx.c and wct4xx.c but there doesn't seem to be much there to be fixed (apparently the crc4

Classification Analysis
Hi everyone, Could somebody explain to me what is the package/function for classification analysis. I am performing analysis of music files in the form of MIDI files. I end up with about 750 dependent variables from the analysis, I also have a number of independent/grouping variables that I set manually. What I would like is to be able to predict which group a particular MIDI files belongs to

Dahdi, b410p and looping from 1 port to another
Hello, Is it possible, for testing, to connect an cat5 straight patch cord between 2 ports of a Digium B410P card and use these 2 ports as a normal dahdi trunk ? I've tried this: One port is set as NT, the other as TE. I would expect timing to come for system hardware so I choose in /etc/dahdi/system.conf : span=1,0,0,ccs,ami span=2,0,0,ccs,ami Results: - both ports lights are green -

Overload Point for OPUS
Hello, Can you please tell me what the overload point is for OPUS in dBm0 or dBV? As an example, the G.711 A law codec has an overload point of +3.14 dBm0 across a 600 ohm circuit. In ITU-T G.100.1 section 5.8 you can read more about the relationship between dBm0 and dBov. In that same section you can see that the G.711 A law, u law, and G.722 codec overload points are also defined.

X101P on a UK BT line ---- txgain issue
I am finding that I have to increase the txgain in zapata.conf to 8 when my X101P is connected to my BT phone line, otherwise people can hardly hear me. This then gives echo issues. Do other people have the same problem on BT lines. I was wondering if I should give BT a call and get them to increase the gain on the line. Strange though as the rxgain is OK and I don't have this problem with

How to lower float charge voltage of an APC Smart UPS unit
You can lower the float charge voltage that APC Smart UPS units such as SU1000NET or SU700NET supply to the battery. This is important when substituting Lead Acid Deep Cycle batteries for the usual sealed maintenance free batteries provided. Here are the instructions: 1) Only do this if you are fully trained and qualified to work on Lead Acid powered UPS. These units contain lethal voltages
