Analog DID, no digits collected

I have a problem with a 1760-v 12.3(8)T router using a 4 port FXS/DID card with the ports in DID wink start mode. Calls made to the DID ports do not receive any digits (both debug voice ccapi inout and debug vtsp all show no digits being collected and normal cause code 16 disconnection) but Telco claims everything is setup correctly and has even went to the site with test equipment to verify. The router is using standard VOIP / POTS dial peers and I have identicle configs running at this same customers other locations so I know it is not a dial-peer error, I have quadruple checked them! Only difference is this is a Verizon Circuit and the others are SBC. I have also tried immediate and delay DID signaling on the ports and that did not resolve the problem either. Anyone have any thoughts on what the issue may be or ran across a similar problem? Thanks in advance!

I have ran into this issue.  The CO was sending the digits, but they were not well received by the
card.  I had a DTMF digit grabber inline with the circuit.  I was only seing some of the digits.  It tu
rned out that there were certain hardware revisions of the CO side circuit board that were incompatible with our
DID card.  I am having a similar issue today.  I am replacing a working 2811 with a new
2911.  The analog DID circuits work great with the 2811, the 2911 sees no incoming digits.
A tip to help troubleshoot.  Hook a phone or a butt-set to the analog DID port.  Go off-hook.  You wont hear dial-tone, but you can dial digits.  This will validate your configuration and isolate an issue with the CO.

  • Can we acquire the Analog input and Digital Input at

    Can we acquire the Analog input and Digital Input at
    the same time? My sensor data include Analog and
    digital signals.

    Hi Chenchen,
    It usually simplifies things greatly if you use analog inputs to monitor both the analog signals AND the digital signals.
    If you abosulutely HAVE to use digital lines, then the answer is, DEPENDS....
    With the correct hardware and depending on how fast you want to collect data and how closely the measurements have to be syncronized in time, it can be done.
    But first, concider using analog inputs to monitor all signals.
    If you need to move forward with both analog and digital acquisitions, then post a new quesion and give us details on the hardware you are using and the other details we will need to advise you.

  • Analog Signal to Digital a Primer

    Many users have analog material sitting around, and they would like to get it into digital form, so that it can be edited. As this material is below SD (Standard Definition) quality, I will address the methods for digitizing it, so that it can be best edited in a DV Project. The output can be a DVD-Video, or other format, depending on what one wishes.
    The process of getting this analog material into a digital form, is referred to as Capturing, and it is digitizing the analog material and writing it to a file, that can be edited.
    One will need some method of getting the analog signals into digital form, and for connecting the analog output from their analog playback device to the computer. Though the analog signal could come from all sorts of devices, I’ll use a VHS tape deck in this example.
    Since a VHS tape deck does not have an A-D (Analog to Digital) processor, and also does not have a a digital signal Out, one needs something in between it, and the computer. That “something” serves two needs: mechanical connection of cables and the ability to convert the analog to digital for use in an NLE (Non Linear Editor). That “something” can be a digital video camera with pass-through capabilities, a device, called a “bridge,” or a capture card inserted into a bus slot in the computer. All three have pluses and minuses.
    The first two methods rely on one having a FireWire connection on the computer and will use the Capture module in the NLE software.
    The digital video camera route is good, as one already owns it. Having one with pass-through capabilities is getting more difficult. The camera also has to have FireWire (FW, IEEE-1394a, or iLink) output, and the computer must have a matching connection.
    An A-D bridge will do the same thing: allow one to connect the analog cables to one end/side, process the analog signals to digital and then output via FW to the computer. There are various such bridges available and two of the most often recommended makes/models are: the ADS-Pryo, and theCanopus/Grass Valley ADVC-110. Products, like the Dazzle lineup, just do not seem to work, or work well. I would avoid such.
    A dedicated capture card performs the same task, with one exception. The card will mount into an empty PCI slot on the MoBo, and have inputs for the analog cables. The card will have chips on it, to digitize the analog signals and feed these to the computer via the PCI slot. These do not connect via FW, but have one drawback: they must, in virtually every instance, use additional software to do the actual Capture, as most NLE’s cannot directly see and work with them. Some of the included software Capture programs are better, than others. One common issue with many of these cards is a loss of sync, between the Audio and the Video. This is usually static OOS (Out Of Sync), in that it is usually off by a fixed number of frames, and does not drift over time. This can be fixed in the NLE, but is extra work. This ARTICLE will give you tips on correcting OOS.
    Now, we are ready to begin the Capture, as our equipment and cables are all ready to go. We have a big decision in front of us - what format/CODEC do we use to Capture our digital files? Since we are doing an SD Project with non-HD (High Def) material, there is one fine choice: DV-AVI Type II w/ 48KHz 16-bit PCM/WAV Audio, using the DV/DVC CODEC. These files will be approximately 13GB / hour of Duration. Storage will need to be considered. These files are also I-frame, meaning that each “Frame” is rendered and available, so that frame-accurate editing is possible. The NLE will not need to do any processing, or conversion of these files, as even the Audio is ready for DVD-Video. Note: there will still be Conforming and the generation of PEK (Waveform Display) files, but the NLE will be able to do this quickly and efficiently.
    Using AVI Uncompressed will get you nothing that you can see, other than larger files. Do NOT use any compressed format/CODEC, like MPEG-2, WMV, MOV, etc., as these will loose data from an already inferior source, and will then need conversion to be used, either with a stand-alone conversion program, or internally by the NLE. You loose quality and then have more work to be done. Do not let the temptation of smaller files lure you into using anything but DV-AVI Type II, and just accommodate the larger file sizes.
    With the file format/CODEC decision made, the cables and devices hooked up, we’re ready to start the Capture. The exact operation will depend on what our equipment choice has been. See above for talk about additional Capture software, if one uses a capture card. Otherwise, we should be able to use the Capture module of our NLE. The first issue is that we will NOT have Device Control, as we would with a Capture from a miniDV tape-based digital camera, where we can control the mechanical aspects of the camera, during this process. As our VHS deck is hooked up to the A-D bridge, or digital camera w/ pass-through, via analog cables, our control signals cannot be sent to it. One would cue up the tape in the VHS deck, and then choose Record/Capture in the NLE’s Capture module, starting the Capture. Instantly, they would hit Play on the VHS deck, or via that deck’s remote control. This is easier the second time that one does it. I sit with the mouse in my right hand, poised over the Record/Capture button, and the VHS deck’s remote in my left hand, finger hovering over Play. It’s then a 1 - 2 push, and all starts. One can stop the Capture, if an unwanted section of tape comes up. The Capture module of the NLE will direct us on how to proceed from there, should more Captures be wanted. Some will just start up at a later point, and write an additional file for that portion of the tape, but some might require that one basically sets up a new Capture session One should investigate just what their NLE will require for doing multiple Capture sessions from one VHS tape.
    When done, one closes the Capture module, and then navigates to the location that these DV-AVI Type II files have been stored in, and Imports them into the Project. This differs slightly from doing the Capture from a miniDV tape camera, as those Captured files are already in the Project.
    Edit away, and Export/Share to the necessary output settings, file type and CODEC.
    What about those VHS - DVD decks, the ones that will burn a DVD directly from the VHS tape? They seem so simple to use, and for the most part are. However, those DVD-Video discs, contain pretty heavily-compressed MPEG-2 AV streams. These MPEG-2's, besides being compressed, are in aGOP structure and are muxed (Multiplexed into one file with both a Video & Audio stream), plus there is often some Menus and navigation in the first VOB, the main container components of a DVD-Video. Many NLE’s can Import the VOB’s, and basically rip the MPEG-2 out of them, but that first VOB can be highly problematic, due to the way that most of those decks do the Menus and navigation. It is seldom 100% DVD-compliant by the DVD-specs. This can be a major problem. This ARTICLE will give you some background and tips on DVD VOB's.
    Those dual-decks are good for doing one thing, regarding the DVD’s that they produce - provide one with an archival DVD-Video of the VHS tape, and not to be edited. However, the VHS side of these works well with an A-D bridge, just like a pure VHS deck does. I would strongly recommend that one does NOT use the DVD-Video portion of these, if editing will be desired. They cause many more problems, than they solve - just use them for an “archive” copy of the tape to a DVD-Video, for playback on a computer via DVD software or a set-top player, hooked to a TV.
    What about film? Well, film is obviously analog, and one needs to digitize this to edit on the computer. The process of this digitizing is referred to as telecineing the film. While one can buy equipment to do this, it is expensive, and involves a lot of setup and testing to get the job done. There are many service bureaus, that offer telecining. Some are better than others. The main considerations are: care in handling of fragile film, how the telecining is done, i.e. frame by frame w/ a liquid gate, or just by straight projection, and then output format for the digitized files. Some of these services will offer a DVD-Video disc. Do not be tempted to do this. See above. Others will offer to write these digitized files to a miniDV tape, and this is just fine. One does then need a miniDV camera, or miniDV tape deck, to then do the Capture from, but the quality and editability will be preserved. The final delivery format would be to put these DV-AVI Type II files onto an external HDD. This saves one from having to do the Capture from miniDV tape, having to have a miniDV camera, or miniDV deck, and only Importing of those files would be required to get them into the Project. Many of these service bureaus will either sell you the external, or use one provided to them. Check out specifications for things like format of the external. FAT-32 will limit the file sizes to ~ 4GB max, and NTSF will have no such limitations. However, if the service bureau is on Mac, and you’re on the PC, their Mac’s can ONLY see FAT-32 HDD’s. Talk this over with the service bureau first, so that there are no surprises later on.
    Hope that this helps,

    Although I now have a Canopus ADVC300 I previously used a Magix 'Movies on DVD' USB device. I found the results from this to be particularly good and, to my ageing eyes, I see very little quality difference.
    I think this is because Magix use their proprietary high quality codec (from their Pro products) to capture the footage. Like DV-AVI it runs around 10GB+ per hour. This can then, very simply, be exported to DV-AVI Type 2 for use in PRE. Note that there are some sound synchronisation issues with the 'out of the box' settings - but the fix is quick and I posted details to the Magix forum.
    Would I revert if I could return my ADVC300 bridge? Probably not - the firewire connection and the PC seeing the box as a camcorder adds to ease of use. In fact I am pleased to have both. There are some things Magix does better than PRE7 (batch exporting each scene as an individual DV-AVI file being just one) and it has smart-rendering which is handy for quick clip splitting/exporting.

  • Convert analog DID trunk to a PRI?

    Hi, I'm trying to figure out the least expensive way of converting an analog DID trunk coming from the phone company to a PRI that I can feed into our ISDN switch. I realize that the analog DID trunk only equates out to one B-channel + one D-channel for signaling but that is fine, the other 22 channels can go unused/unmapped. I'm not too familiar with Cisco gear but figured maybe two MC3810s back to back or a 2610 with the proper add-ons (VIC-2DID + ?). I also need to make sure that the dialed phone number is preserved within the signaling (DID->D-channel). Any low end hardware suggestions would be greatly appreciated. Thanks for any info, Brian.

    When receiving an inbound call from a plain old telephone service (POTS) interface, the DID feature in dial peers enables the router/gateway to use the called number (DNIS) to directly match an outbound dial peer. When DID is configured on the inbound POTS dial peer, the called number is automatically used to match the destination pattern for the outbound call leg.
    To configure a POTS dial peer for DID, enter the following Cisco IOS commands beginning in global configuration mode:
    Router(config)#dial-peer voice number pots
    Router(config-dial-peer)#direct-inward-dial

  • How to convert a analog signal to digital signal

    Hello,
    How to convert an analog signal into digital signal such that every sample of analog signal corresponding to 1.2V will be represented as '1' in digital signal and other samples of analog signal(that are not 1.2v) will be represented(converted) as '0' in digital signal.
    And how to display both wavefroms or signals in graph indicators.
    Thanks.

  • How can i change analog waves into digital waves?

    we had labview lab last week.. were doing fine if we have instructions unfortunately the professor will give us an exercise regarding baseband signals spectra.. were trying to download a trial software but we dont have any luck. the question asks for us to change analog waves into digital waves, measure the amplitude of the 5-th harmonic using spectrum analyzer.. i hope you can help me thnx..

    After you are successful getting LabVIEW on your computer, put together something to at least show us you're up for learning.  Then we can guide you to a solution that you've developed (mostly) on your own.

  • Analog data to digital data conversion in labwindows

    Hi
    Is there any library function available in Labwindows for converting Analog data to Digital Data..
    Thank You

    shoukat,
    could you please provide some more information about the background of this question? Is there any link to motion control (this is the Motion Control forum)?
    I don't understand exactly, what you are looking for. All data that you use in a programming environment are digital data - regardless of the data type. Are you looking for a data conversion from floating point to binary (e. g. a boolean array) or are you looking for data acquisition hard- and software?

  • When converting analog video to digital to my macbook the audio desyncs halfway through. Any ideas?

    I am trying to convert Analog video to digital to my Macbook for work, and every time I run it through my converter the audio De-syncs about halfway into the video. Does anyone know how to go about fixing this issue or have had similar issues to this? I have no issues when converting to my PC, but only my Mac. Thanks!

    Hi Rick,
    I am extracting the material from the dvd directly using handbrake. The file that handbrake creates lands on the desktop. I then ammend the end of the filename from mp4 to m4v. Following this I click and drag the file onto the itunes icon in the dock. I can then download it to the ipod no problem. The dropouts occur no matter where I play the file. In other words, on the desktop (with QT), in the itunes library and on the pod.
    I went back and looked at all the dvd's that are giving me this trouble. The culprit seems to be that the audio signal is in LPCM (linear pulse code modulation). Just for the **** of it, I tried to rip one track using handbrake changing the sampling rate of the audio to 48,000 Hz which I believe is what LPCM uses (previously I had set it at 41,000 Hz in handbrake). But no go, still has dropouts. One of these problem dvd's has a second audio option in AC3 (2ch). As a test, I ripped one song using that. Dropouts are gone. However, the audio is a director's commentary (on the music video he shot) with the music in the background, so it's not what I want.
    Is there any way to convert LPCM to AC3? Or any other way to fix this dropout problem.
    Thanks,
    Pete

  • Best Quality importing 8mm analog and 8mm Digital Video Tapes

    Hi folks,
    I have imported several 8mm analog and 8mm digital 8 video tapes using a Sony Digital 8 camcorder and firewire cable into my iMac. As referenced many times, the quality is so-so due to the loss of half the lines; a deficiency in iMovie 8.
    I just acquired a copy of iMovie 6HD to address this. Both are now installed on my iMac.
    Would I lose any video quality if I first import into iMovie 6HD and then export from HD to iMovie 8 using the "Import from iMovie HD" option. In other words, does using iMovie HD as an interim step address the "line loss" problem associated with video tape input that exists in iMovie 8.
    For diehard HD users this may seem counter-intuitive but I like some of the title and transition capabilities in iMovie 8 and am willing to sacrifice some editing function/capability if the original video quality is not compromised.
    TIA,
    Ed

    Bengt,
    Thanks for the reply. So importing first to HD doesn't solve my problem. I need to edit in HD and publish in HD or lose half of the interlaced video.
    I am aware that importing from tape directly to iMovie'08 or 09 or 11 loses half the video. I was hoping that using HD as an intermediate would solve my problem.
    Guess I need to learn editing in HD.
    Could you please just confirm. I have become very comfortable editing in '08 and my first few looks at HD aren't getting me there....yet.
    Thanks again.

  • Settings for ripping my CDs to future proof my digital collection?

    I ripped my CD collection about 10-yrs ago at whatever the standard bit rate and quality settings that were average at the time. I spent weeks going through all of my discs doing this and I can't help but feel that all of that work is obsolete by today's standards. I'm considering re-doing a percentage of my discs at higher quality settings.
    1. What is considered good settings by today's standards?
    2. What settings might I consider using to futureproof my digital collection for the next 5-10 years?
    Thanks!

    That wasn't very good quality even at the time.
    Re-rip as Apple Lossless (ALE).  That will be the equivalent quality of the original CD but at about 60% the size.  Except for staying on top of whether or not ALE is still a major standard in a decade or so you should never need to re-rip because it won't get any better than the original quality.

  • Directly convert the analog signals into digital without passing through FPGA

    To whom it may concern,
    I am using a SCB-68 board R-series and I have a couple of technical questions:
    In my system at the moment 8 analog channels are connected to the 8 input analog ports and then data are sent to a FPGA (PXI system 7852R). I am planning now to add other 4 channels to the system. Since over the total 12 channels I just need a very fast acquisition mode (using the FPGA) for 6 of them, while the other 6 can be sampled in a ms scale, I was wondering if you can suggest me something that I can use to directly convert the analog signals into digital and in this way used many unused digital signals provided with this model.
    Thanks in advance.

    yes it is correct, what do you need is:
    software + (pc) + PXI + cable + chassis + C-series module
    With embedded controllers, there’s no need for an external PC
    With PXI remote control kits, you can control PXI systems directly from desktops, laptops, or server computers.

  • Analog distortion and digital's lack thereof

    Djokes wrote:
    "analog is distorting - without a doubt - tape decks were like compressors in a way and that is what being simulated by e.g. mcdsp or crane song... However, using no eq or tape deck - the distortion is minimal.... but analog is distorting what is actually there - digital is not - cuz it aint "Seeing" it all....so the distortion will be false...And we dont need to start a discussion about that we like the distortion that analog brings - do we now?"
    Let's start one though shall we.
    First I fail to see how digital isn't seeing it all. Unless you're talking about inaudible frequency ranges which I will admit may be more important than not. Digital lays it all on the table. No compensation, no analogesque minimal distortion. So this would be a true picture of the audio right.
    I mean if you're talking about the nuances of environment then digital still captures that stuff as it's mic'd. The thing digital doesn't capture is the distortion signature of the analog device. Now if you've been trained over decades to appreciate that distortion, hearing digital which lacks that of course would lead one to say it sounds cold.
    The question is whether that distortion is the signature of quality music, or whether a talented producer/mixing engineer, can create a signature digital distortion which is either as good or better than analog. I'm a firm believer in the latter though I will admit we haven't surpassed analog yet. But I also believe the answer isn't in trying to emulate analog, but rather using the digital for its own strengths to create something all together new.

    then we'd have to start a new topic called what is accurate:-))) Anyway, listening to a guy playing an acoustic guitar live would by many be considered a true source of audio.... So if we have a mic that can actually capture the movements the gas molecules in air makes and translate those correctly into currents - then we can assume that at least the mic is giving us the true source...If the mic "Which it cant" could translate the audio one 100 percent accurately into current the mixing board would only "see" current actually VOLTS and treat those as such...if we were to apply no eqs and no effect at all - the next step of inaccuracy would be your speakers which would have to translate the currents and make the membranes vibrate - which would then again compress and rare-fact the gas molecules in the air - thus making u able to hear it....
    The mixing board is treating the current coming from the mic more or less constantly the way it came from the mic - the digital converters are only treating what comes from the mic 44100 times per second - this is why analog is called analog and is seen as treating the signal the way we hear it....
    What do we hear - and what is there and what is our brain doing.....
    the air that is being put in motion by a source being a true source or speakers is hitting our ears with the speed of sound - our ears are like a mic we a picking up differences in the molecules and our brain is translating it into what we call sound... Digital audio is actually exploiting our imperfections this is why we only need to sample 22050 times per second (Hearing Threshold) - the actually reason for sampling at twice the freq of hearing is because of the problem that causes the low pass filters to be there in the first place...(why the lowpass filters are needed would be too long to desribe)
    The reason for 44100 is the hearing threshold of 22050 Hz - I dont really no anyone above thirty that can hear above 18000 Hz and make use of what he is hearing - so why not sample at 16000HZ - or 32000 Hz - the reason is mirroring cuz of imperfect sinuses - and facts of a physical law : There can be no 90° Low pass filter....
    An EQ works with phase displacement - what actually happens when u cut 4 KZ by 4 db. is that the original signal is being phase displaced at the freq. u enter - what happens is that those freq.'s are being less amplified - There are physical laws about waveforms e.g. when two waves layer each other at the same maxima you will gain 6 db aka doubling the amplitude...when two waves hit each other where one has maxima and the other minimum you'll achieve complete cancelation...
    what really happens when u talk analog dist. is that the sinus(Wavesform) is being distorted so it looks more like a triangular waves form.... This gives us a feeling of loudness and warmth...
    If u want your digital mix to sound loud - take the "beautiful" sinus and turn it into a triangle by changing the gain - after that you will see the wave form being cut at the top and bottom but it aint sounding bad - only louder - Unless u overdo it:-))))
    There's a lot more to it than what I just described - and it is quite interesting - If u go to amazon.com there are two kind a books about his stuff...1) The book describing it fragmental like I just did and Books that really describing it according to physics....Latter mentioned are VERY dry but if u take the time and have the interest you will find them real helpful and it will also change the way you "Look" at audio and mixing and recording
    This is a huge topic consuming man since the day of recording audio...

  • Sync'd Analog In and Digital In

    Hello,
    I am a new LV user and am having difficulty with my vi. I'm attempting to use a PXIe-6361 to output hardware timed digital bytes for external multiplexer control for channel select, and then do an analog read of that selected channel. The clock used to control the digital output is synchronized to the analog in read and is running at speeds ranging from 20kHz to 100kHz (manually adjusted in between executions). When this system is running the scope shot looks good (See below...A2 is trigger for AI, and bit lines are the digital mux addresses).  The issue I am having is related to filling an array with the samples collected from each channel and replacing them each time they're sampled.  The read of the digital output value used for an array column pointer to replace older data does not appear to stay sync'd and causes the data to jump around among various array columns.  The VI is attached, any ideas for a fix out there?

    I just added the Input Buffer vi, set it to 5000 and still see the error.  Seems the error is related to the time to collect triggered samples. I am running at 2MHz sample clock rate and when the sample size get sets to approx 50 or smaller the error shows up.  This would be when the total sample time is 25uS or faster.

  • Convert analog video to digital using a miniDV camcorder

    Hi hi
    So I want to convert some old analog videos I have from about 10 or so years ago to digital so I can edit them in iMovie HD. I've been reading a lot of the forums around and have successfully (I think) connect the analog video camera to the the miniDV (a Sony Handycam DCR-HC30E) using that A/V jack in the digital recorder and the analog to connect them. And the digital recorder is connected to the computer via firewire. So that's all right.
    But now I'm up to the stage where I need to import it into iMovie HD (version 5.0.2) and it's been stubborn and not doing anything. I press play on the analog like people have said but iMovie just says "Camera no tape" and the "import" is unclickable.
    Please please please please help! I've no idea what I'm doing wrong!
    So just for quick reference, I'm using:
    iMovie HD 5.0.2
    Sony Handycam DCR-HC30E (Mini DV) and
    Panasonic NV-VZ1 (analog video recorder)
    P.S I don't want to have to record onto the the mini DV tapes because I've got none.
    Thanks!

    Hi catspaw! Thanks for replying
    I probably should have mentioned before that I did change the 'A/V to DV out' to on, and I think that's the same as "passthrough"
    And I've tried suggestion 2 as well, but to no avail! The connection either dropped once I took the tape out or it started to film on my iSight camera! Which is bizarre because my iMovie usually does not let me film with it! I've also been able to film with the camera connected to the computer and recording on the computer and see what I'm fliming on the computer.
    But thanks for your help anyway!

  • Converting analog video to digital

    I'am currently running on a new powerbook G4 OS 10.4 and having great difficulty getting my computer to read my camera. The problem is that my camera is connected to a digital converter. Dazzle Hollywood DV Bridge. My camera is a Sharp that runs Hi-8 tapes. If anybody has any clue on how to get my computer to recognize this set up I would greatly appreciate it.

    Brian,
    I have the same Hollywood DV set up and every now and then it acts goofy. Take a look at the lights at the top. the lowest one (AtoD) should be green. (analog to digital) If all lights are red click the switch on the top rear of the Dazzle unit.
    Also use the firewire port on the rear. Seems like mine has an issue with the front.
    Lastly save and exit the I movie program and restart AFTER hooking up and selecting Ato D.
    Make sure you set the switch on iMovies interface to "camera".
    One last thing. You have to work the camera by it's controls. You won't get them to work through I movie.
    If this doesn't help hook up a VCR to the DV Bridge, Hit play and see if it sends through to iMovie. If it does it's your camera or connecting cable.
