Channel seperation in PRI

Hi,
i have a router with one pri and one bri. i want to seperate two channels from pri to bri for connecting video conference box. is there a configuration example and is there any restrictions ?
Regards
umit

hi
Afaik u can create seperate dialer interfaces and bind them under the pri interface,under the pri interface try configuring this ..
interface BRI1
dialer pool-member 3 max-link 2
Dialer pool-member is the dialer pool configured .

  • I am not able to set high and low limits for each channel seperately using LabWindows/CVI

    I am using AI_StartAcquisition and AI_ReadAcquisition functions to acquire data using PCI 6025E DAQ card and iam using Lab/Wuindows/CVi5.0 software. But one of my transducer has its range in +/- 500 mV soi need to set the high low limits of each channel seperately for that i am using commond string function(cmd) but still i am not able to set the limits properly. Does anyone has any idea about this trouble

    You can set the gain on a per channel basis by using the lower level functions. (As opposed to the easy i/o functions.) For example, look at the "SCANsingleBufSync.C" NI-DAQ shipping example that uses the SCAN_Op() function. It's gain parameter is an array of gains that will allow you to change the input limits for each channel separately.

  • How do I find out how many B channels on my PRI line.

    We recently upgraded from 8 lines to 23 on our PRI, and want to confirm that the telco has indeed added the lines. We have the PRI line into a Cisco 3640 router.

    "sh isdn status" and "sh isdn
    service"; look for all of your
    B channels to be in service.

  • Is there a way to simplify this? applying functions to 16 channels - software trigger

    hey,
    at first I want to appologize for hurting everybodies eyes.
    Today I ended up with a pretty weird VI and I was wondering if there is any way to do this a littler easier.
    Basicly I want to acquire 16 channels from a device. Unfortunately the device doesn't support analog trigger, so I had to create a software solution. So, I m reading 100 samples on all of the 16 channels in a while loop and compare the first channel, if its value reaches a certain threshold. If it does I end the while loop and enter a for loop, which read 100 samples 10 times. Before exiting the for loop I seperate the 16 channels - so I end up with 16 different arrays of 10 x 100 samples. Then I reshape the Array in order to get a one dimensional array with 1000 samples. At that point I have to do that for every channel seperately. After that I add the 100 samples which I acquired in the while loop in the beginning (which was the trigger) to the 1000 Samples Array. I end up with a array for every channel, which is 1100 samples long.
    As you could see in the attached image, this looks pretty confusing in the end. Is there any way to make that easier and look nicer?
    I know, I could add functions to reshape the arrays in order to end up with an 3 dimensional array (16 channels x 10 x 100 samples) then I could process everything in a for loop - but I guess that would take longer to calculate in the end?!? Any good ideas on that, except buying new hardware with a analog trigger?

    as far as I know, my hardware only has memory for 4095 Samples -  when acquiring 16 channels at once, I am able to read chunks not bigger than 256. is this right?
    I am not sure, if I still have some DDT in my latest vi left when converting the sample points as arrays of doubles. I will check that tomorrow, can't remember how I did that in the end. But everything seems to work finde so far. Thank you.
    However, there are still some basic questions:
    I have different parts in my vi, which relate to each other. For example, I have a array which is loaded from a file & edited by the user.  When finishing editing this array the user presses a button and continues with a different part of the vi, which uses the entered data. Therefore a part of the vi should not run before a other is finished. I used a combination of a event structure and a message queue. Is there a simpler way to realize such a construct?
    Just was thinking about creating Sub-VIs - apparently I could get rid of the queues then.. will try that tomorrow..
    If I create an empty array in order to enter values by the user during runtime, the array size increases at the moment I enter a value. In case I entered a value in the wrong field und want to deleted that value again and reset the arrays size to the size it had (before I entered the value)  - how do I do that? There is the right-click-option 'reset to default value', but this only sets the value to 0 in an numeric array, not deletes that field (row, whatever..)

  • HDV Channel 3 mic...?

    I am editing using FCP Studio 2. Recently a bunch of footage has been recorded for me as the editor on the Cannon XLH1 Camera. The footage is HDV and recorded on mini dv tapes.
    A mic was used that was connected to the 3rd channel for audio. I have been told that capturing in Final cut pro will not provide me with the channel seperated of just the mic.
    If anyone has any ideas of whether or not this is true, or if there is a work around. That would be great!!
    Thank you.
    Jesse

    couple things to try maybe:
    1) set the camera to downconvert over firewire to DV for the ch3&4 capture pass and see if you can route the audio to capture from 3&4 from that downconvert
    or 2) take the audio out direct from the camera (set monitoring to 3&4) and run that to the Mac's line in jack and capture it from there (then sync and merge in FCP)

  • How to show different recorded audio channels in timeline

    I've recorded an interview with two microphones (one was really bad, so I only want to use the other recorded microphone). I imported the clip from the tape camera into FCP X. Now in FCP X on the timeline I only see one audio track when I seperate it from the video. The two microphones seems to be 'mixed'. This was different in FCP 7 where you see both audio channels seperated.
    How do I manage to seperate the 2 audio channels into 2 channels. I'v troed with Channel Configuration via Audio Inspector but I do not understand it.
    Thanks, Pim

    Select the clip in the timeline and in the audio tab in the inspector in the channels seection switch to dual mono. You can switch off a track here if you wish.

  • Multipexed channels in MODBUS with memory tag?

    Hi
    I have setup where an analog input module multiplexes it's four channels into one MODBUS address. I do this with the following procedure:
    - channel one is written to a certain MODBUS address (e.g. 30016)
    - then I write a number (e.g. 12) to an other certain MODBUS address (e.g. 40001)
    - channel two is now written to the first (30016) address
    - I write a second (e.g. 16) number to 40001 MODBUS address
    - channel three is now written to the first (30016) address
    - and so on...
    I am using LabVIEW DSC an I am wondering if I could solve the problem somehow with a memory tag.
    I can do it by hand already (write tag / read tag) but I need to have those four channels seperated in the database
    thanks in advance
    wolfram

    I guess this question got answerd already by the DSC enthusiast
    Create four Memory tags, one for each channel. Wire these channels' values to the respective Memory Tags using the Write Tag VI. Also, enable logging on these Tags so you have the data in the database.
    Then cycle through these Memory Tags and write them out to your Modbus 30016 Tag.
    Hope this helps.

  • Multiple channels from GigE camera

    Hello NI Folks,
    I am using a GigE camera for my Machine Vision application. I have to save data from all three channels coming out of Camera.
    I am using Example VI from National Instruments 'Grab and Setup attributes.vi' to get attributes and save Image. But the problem is this example VI has capability only to grab data from one channel. Anyone please give an idea for Which part of thIS example VI should I edit to grab all the three channels ??
    I checked this issue even in MAX. I selected all three channels in MAX and tried to take a snap from camera, but there is only one image captured, there is no option in MAX to view all three channels. I am attaching the MAX scrrenshot below which shows all the channels from my GigE are activated
    How to make Labview to read all the three channels from camera ??
    Regards
    Neo.

    Hello Mr.Alexander Glasner,
    This is the camera I am using
    http://www.automationtechnology.de/cms/index.php?id=243&L=1
    It is used for Laser triangulation technique. this camera gives out  3D data in one channel, Intensity data in other channel, grey scale Image in third channel. All these these channels comes out ofcamera through a single Gigabit Ethernet.Camera manufacture provided a software with which streaming of desired channels is possible. But I want to do it in Labview. Is there any block in IMAQ library to isolate these channels from GigE Interface ?
    My point with MAX is, MAX is able to grab all the attributes including its channels names DC0,DC1,DC2. But it is not able to display three channels seperately when selected.

  • Number of channels

    I have this Dial Peer:
    dial-peer voice 12 pots
    destination-pattern 12T
    inward-dialing
    port 2/0:D
    My question is:
    Is there a way to make the calls using this DP use a certain number of channels?
    For example 14 to 23?
    Thanks in advance.

    this might be what you need -
    The customer had two different users and he wanted to split a single T1 PRI service between these users so that one user would use certain B channels and the other user would use different one for outwards calls on the CME router.
    The phone company was able to assign these B channel groups with different number ranges for inwards calls.
    There is a new feature in 12.4 code that allows you to define individual timeslots of the PRI and assign them to different trunk groups. These trunk groups can be used instead of a voice port in a POTS dial peer, so you can direct calls to very specific B channels on the PRI. Following is a config that demonstrates this feature using an E1
    controller E1 1/0
    pri-group timeslots 1-31
    trunk-group Customer1 timeslots 1-10
    trunk-group Customer2 timeslots 11-20
    trunk-group Customer3 timeslots 21-30
    dial-peer voice 1 pots

    trunkgroup Customer3
    dial-peer voice 5500 pots
    trunkgroup Customer1
    description - Customer 1 : access code 771
    destination-pattern 771
    dial-peer voice 5501 pots
    trunkgroup Customer2
    description - Customer 2 : access code 772
    destination-pattern 772
    dial-peer voice 5502 pots
    trunkgroup Customer3
    description - Customer 3 : access code 773
    destination-pattern 773
    In this case, Customer1 users would dial 771 as an access code, Customer2 would dial 772 and Customer3 would dial 773. These access codes would 'steer' the call to the appropriate timeslots on the PRI.

  • Photoshop not presenting alpha channel as expected (like I'm seeing GIMP does)

    Greetings,
    I have a need to edit the channels independently (the values in my image mean things numerically rather than just what it looks like visually - so I need to edit the grayscale values in each of the R - G - B - and A channels seperately).
    I've searched through google and other forum posts and others bring up the concept of not understanding alpha versus transparency - but I have yet to see an explanation that fully explains what I'm experiencing.
    The closest was http://forums.adobe.com/message/2563436#2563436 But while I saw the exact same symptoms being described, the specific question was never really answered.
    Hopefully, a concrete example with pictures will be able to communicate the issue and solicit a useful explanation and/or solution.
    While, I'm specifically working with an RGBA image, below is a screenshot of a PNG that demonstrates the exact same behavior or symptom.  The screenshot below represents the PNG inside GIMP and PS CS4.  BTW, if you'd like to see or play with the image yourself, you can grab the same image at http://www.libpng.org/pub/png/img_png/imgcomp-440x330.png
    GIMP, interestingly enough loads the PNG as expected - I see the transparency of the image treated as a true alpha channel.
    In PS CS4 however, the transparency seems to be somehow embedded in the Red - Green - and Blue channels; but NO seperate alpha channel.
    I can create the alpha channel through Select - Load Selection - Layer 0 Transparency - and pasting that into a newly created alpha channel - but the color channels still have the transparency mixture symptom - rather than showing the JUST the color component of that channel.  (Note the channel differences of the GIMP's Red Channel versus PS's Red Channel  - Said in another way, the yellow ball in the upper left of the image should have a red value of 255, so the Red Channels grayscale upper left ball should be white like it is in GIMP, rather than Gray as it is in PS).
    I never thought I'd experience GIMP being superior to Photoshop - so hopefully somebody can shed light on what is going on - what configuration I may have myself in - or a process to get the channels seperated out in the manner I wish to work with them.   Furthermore, maybe somebody can educate the Photoshop community what the difference between transparency and alpha[transparency] is.  I haven't found quite the right explanation that makes the light go off in my head yet.  As best as I have gleened "Alpha", which can be applied to any kind of channel, typically is in reference to transparency - and is applied as a document-whole transparency (as opposed to transparencies applied at a layer level - such as a layer mask).

    I think I've finally determined that modern Photoshops have gone in a different direction that I feel "Alpha" should be done.
    (good or bad).
    Here are the steps and/or details of how I arrived at that conclusion.
    If nothing else this has been very educational on how Photoshop treats alpha.
    - Import your alpha'd PNG with SuperPNG format (see above on how to make sure you use the SuperPNG plugin to load the .png).
    - In the SuperPNG dialog select "Alpha appears as seperate channel"
    - Create a layer from the Background and Delete the original Background
      (since the Background is locked and we can't edit the Background - we want to add a layer mask based on the alpha)
    - Ctrl-Left Select the "Alpha 1" channel - Ctrl-C - and hit the "Add Layer Mask" button (square with the circle at the bottom of the LAYERS rollout)
    - For this demo and clarity, I went ahead and deleted the alpha "Alpha 1" that came in through the SuperPNG plugin
    So now I have the Layers like I kindof expected the main document to just come in as (kindof though - it is presented in a Layer Mask rather than Alpha Channel).
    What is interesting - which you'll see if you toggle the layer mask on and off
    (shift-click the mask thumbnail in the layer)
    Note how the thumbnails in the channel views render differently during the toggle.
    When the mask is off you see the individual color channels like I expect - black where there is an absence of that color.
    However when you enable the layer mask - the individual color channels show in semi-transparent/checkerboard.
    So this is exactly how the color channels are presented when loading in a .png (WITHOUT the SuperPNG plugin) or an .rgba
    ..you get the semitransparent views of the color channels - BUT the difference is - you have no way to directly see or edit the Alpha channel.
    nor are the color channels represented as completely opaque versions.
    What is really interesting - it is there though - if you Ctrl-Left Select the layer, Ctrl-C, and "Add Channel Mask" - you'll get the Alpha mask.
    HOWEVER, the big issue is that you can't toggle or edit the Color-Channels like the Layer counterpart above;
    they are ALWAYS the semitransparent/checkboard version;  AND now we basically are double applying transparency
      (due to the still embedded alpha/transparency AND the newly create "Alpha 1" channel)
    I think this a bug (or a poor reimplementation of modern Photoshop releases; I believe older Photoshops used to break out Alpha in the "arguably correct" way - and in fact the way GIMP currently does).
    Or maybe there are other explanations - like abstracting some of this complexity away from less advance users, etc?
    So the SuperPNG plugin was useful in experimenting, understanding, and demonstrating what is going on.
    However, if I'm trying to read in .rgba directly, I don't think I have a way of making the "Alpha appear as a seperate channel" as I think any image with "alpha" component should.
    (png, tiff, rgba, etc).

  • PRI Activity

    Is there any way to watch a live report of my PRI activity?
    I've been getting complaints from staff that they are unable to dial out at points, and I want to see how busy our PRI channels are at any given time. We have two PRI's and only 160 people in our office. I highly doubt all 48 channels are being used at one time, so I want to see if all channels on both PRI's are receiving and dialing out calls properly. I've contacted our Telco about this and they say both PRI's are running according to them.
    Any ideas, please let me know.
    Thanks.

  • Measure telephone traffic on an ISDN PRI

    Has anyone developed an EEM Scrip to measure telephone traffic on an ISDN PRI interface on a voice gateway?  Preferably the traffic measurements would be in Hundred Call Seconds (CCS) or Erlangs. It would appear that the “show isdn service” command could be used to determine the state of the individual “B” channels on the PRI.

    If the "show isdn service" command gives you what you want, then you could build a policy using the timer event detector (watchdog timer) to run the command periodically and produce the desired reports.  I don't know of anyone that has already done this, though.

  • Changing baseline of channels

    Dear All,
    I am working with NI cRIO-9215 with BNC (HI-speed USB carrier device). I am measuring 4 multiple channels. They all have the same same baseline i.e "0". I want to change the baseline of the 4 channels so that I can see them more clearly in one disply and not on top of each other. Any ideas?
    Best regards.
    Munir 

    There are at least two ways you can do this in SignalExpress.  Using either the DAQmx Assistant Step, or using the Formula Step.
    To use the DAQmx Assistant Step, drop the step and select the channels you want.  For each channel, change the "Custom Scaling" option from the default of "NO SCALING" to the "CUSTOM SCALING" option.  Using a custom scale you can change the values for each channel in a number of ways.  If you choose the "Linear Scale" option you can apply the formula "y=mx+b" to each value.  If you change the "b" value you are applying a horizontal offset.  If you make "b" a different value for each channel the graph will show each channel seperately instead of stacked on top of each other.  This assumes that your original signals are directly on top of one another and you want to instead see them each seperately but still on the same graph.  You can use the "Custom Scaling" option to manipulate the channel values in a number of other ways and each channel can have its own unique scaling formula.
    You can also use the SignalExpress "Formula Step" to apply an offset to each signal.  However, in this case you must drop one step for each channel as each formula step can only modify one signal so it sounds like you will need 4 formula steps to do this plus the original step you are using to get the channels initially (I assume you are using the new DAQmx Assistant Step since the cDAQ device you are using is only supported by this step).
    Either way will work.

  • "PRI Idle" timeslots always open with G729 configuration between 2 Meridian PBXs

    Is it possible to configure support for the below described requriments with Cisco routers/devices?
    Topology:
    2 x Meridian SL-1 PBXes with a Cisco network between them to support the following requirements:
    -QSIG CCS signaling, Euro ISDN, PRI net5
    -The signaling channel (D-channel) is transparent (P2P)
    -All B-channels (30) should be open towards the pbx’s in both ends
    -No traffic to be sent over the wan  unless there is any calls going (spoofing)
    -The pbx chooses which B-channel to use for a call, signals it, and the Cisco routers must then "unspoof" this channel
    -Codec to be used G729
    A collegue was suggesting this way to solve it:
    -Configure all the channels on the PRI on the routers/gateways connected via PRI to the to be open permanently
    -Congure timeslot 16 to 64kbps transparent
    -Configure the othe timeslots to G729 and Voice Activity Detection to make sure no data will be transmitted unless there is any speach going over
    Anyone configured anything simliar before?
    I guess a challenge would be to have the timeslots open with g729 configured?
    Best Regards
    Ørnulf

    Paolo,
    do you think that simply configuring switch-type QSIG would helps us achive the following requirements:
    Have all the channels beeing up and connected permanetly.
    Have the timeslot 16 set to 64kbps transparency
    Have the other timeslots set to G729 og Voice Activity Detection.  (Target: to have no data going across unless there is a call going across(voice) )
    Our customer calls this feature PRI-IDLE on their Meridians.
