Point to point 128 kbps

hi all,
im new to VOIP,i have 2 offices 10 km diff, i would like to implement ip telephones for communication between these 2 offices.my equipments are 2801 routers 2 no's and WIC-1T 2 no's point to point 128kbps leased line.maximum 10 users will use ip phone's in this scenario. what all things are required extra other than IP phones.
how can i configure these 2 routers for this scenario.whats the encapsulation for this configuration.pls give me the sample configuration also.
any post will be appreciated with proper rating.

You will need a switch at each location for the IP phones to connect to the network. Preferably, you would have a switch capable of delivering power to the phones, such as the Catalyst 3560-24PS. You will need either Callmanager or Callmanager Express for call processing. Callmanager Express can run on your 2801 and will support up to 240 phones. Callmanager is a much more scalable product and runs on separate server hardware. Depending on the number of lines at each location you will need a VWIC card in each router to support local dial tone. Examples are the VWIC-1MFT-T1 for PRI and the VIC2-2FXO or VIC2-4FXO for analog lines. You will also need to take bandwidth into consideration. G.711 calls take approximately 80k and G.729 calls take approximately 24k. 2 G.711 calls would take up the entire circuit. If you're going to be running several calls across this link as well as data, you will need to consider increasing the link speed. Also, Callmanager Express has no provision for Call Admission Control. CAC is the ability to limit the number of calls across a given link in order to avoid quality degradation. You will want to employ QoS mechanisms so that voice traffic gets preferential treatment no matter how much bandwidth you have. Take a look at the Qos link below for an overview. The configuration required would get quite lengthy for this post, but the admin guide below will give you a good place to start.

Error -50 when trying to convert to 128 Kbps AAC

I try to convert all my files to 128 KBPs but about halfway through one of the songs gets an error (-50) and it wont go on. I wanted to do this because I heard it makes the songs take up less room and my iPods almost full. If it helps any I'm using the latest version of iTunes on Windows 7 65 bit.

Unless you happen to catch the name of the song it's syncing, I don't see how you are going to narrow this down.
While syncing, if you click on the ipod in the left list, you can make the little triangle point down. Then click on the word Music underneath that. (Not the main music library, in other words)
There will be little circles next to each song when that song is getting synced. There will also be the song name in the top oval. If you happen to catch that song's name, you could uncheck it and itunes won't try to sync it.

Using the "Convert higher bit rate songs to 128 kbps AAC" feature...

I recently discovered the "Convert higher bit rate songs to 128 kbps AAC" feature and used it to copy my entire 70 GB music library to my 64GB iPad. The music library now occupies only 45 GB. Awesome!!!
Unfortunately, the whole process took well over 24++ hours on my quad core Windows 7 computer (takes about 6 seconds per track). Questions:
1. Is it possible to speed up the process? Even though I am using iTunes 64-bit version, it seems that at no point is more than a single core being used at 33%. Seems to me like overall 8% of the CPU (33% / 4) capacity is being used for the conversion and 92% is being left idle. Is this just bad programming or is there anything I can do to speed up the process? Others see similar problems?
2. Now I have already started dreading the day, I need to restore my iPad (e.g., when OS version 4 becomes available). I would hate to have to do this process all over again. Should I need to restore my iPad, is there anyway I can force iTunes to back up the 128-bit AAC versions on my computer and restore it up from there?
Any insights into both these questions will be deeply appreciated.
Cheers,

Thanks for the response.
So, I am wondering why iTunes uses only 8% of the processor power in converting the songs.
Possible reasons not to grab more of the CPU power (1) maybe the process is I/O bound due to all the writing, and is not processor limited? (2) since conversion is almost always a background program, and the user will typically have other things going on, maybe it intentionally limits CPU use?
I ran a few quick experiments (out of curiosity) and think the answer is #2. No apparent technical reason but potentially a limitation introduced by Apple's engineers to maintain a good user experience (for some people at least). I fired up 4 instances of dbpoweramp and ran multiple conversions and found that the process goes faster than what iTunes can do by an order of magnitude. With luck, someday Apple will have an option for users to select how much of processor bandwidth to be allocated for the conversion.

"high-quality" of 128 kbps versus higher rates

In a previous discussion a user was asking re difference between different bit
rates one answer clearly expressed dissatisfaction with 128 kbps for music such as instrumental and for music that is intended for streaming to a good stereo.
wondering if other users have a similar experience -- I am in the process of
importing a huge number of files and I wonder if its worth going to the higher
rate for all of my favourites.
I have a lot of space at the moment on my hard drive but I don't want to waste it if I don't get much improvement in quality. Unfortunately I can't test
it right now because I don't have a decent stereo system yet.

This was originally posted by the incredible Sparky the wUnderdog with help from MacMuse:
As a general principle, you can fit more CD's on your iPod if you encode at lower bitrates (making smaller files), but at the cost of audio quality. Apple Lossless promises to capture all the data on the original CD (thus preserving quality) but coded so the file takes half the space. MP3 and AAC (an implementation of variable bit rate MP4) both eliminate some of the information on the CD in order to compress the digital recording into ever smaller files--the lower the bitrate, the smaller the file, but smaller files mean more information lost and consequent poorer sound quality.
AAC files ripped in iTunes certainly sound better than its MP3's, with audio quality close to the best LAME MP3's at higher bitrates. With the type of music I listen to most often, sound quality declines substantially as bitrates fall below 256kbps, but LAME or AAC @ 256kbps sounds pretty darned good, and at 320kbps LAME alt-preset-insane is amazingly faithful to the original. However, many users claim that with the music they listen to they can't hear the difference between 192 or even 128 kbps files and the original CD source, so they naturally choose lower bitrates to fit more "songs" on their iPods.
CDs take approximately 10MB per minute of music; Apple Lossless takes 5MB/minute; LAME insane takes 2.5MB/min; AAC or MP3 at 256kbps take 2MB/min; and iTunes Store files (AAC@128kbps) take 1MB/min. At these rates, a 20GB iPod (really 18.6GB) can hold anywhere from 30 hours to over 300 hours of music. (iPod marketers express this potential playback capacity as "songs," figuring 4 minutes per song--thus 300 hours at 128kbps = 4500 "songs.") You will need to listen to samples ripped with different bitrates and codecs to determine the optimum tradeoff point for you between quality and quantity. It's worth taking some time to do this at the start as it sure beats reripping everything in your collection 2 or 3 times to get it right later.
So far as convenience goes, nothing beats iTunes's one-step process. To change bitrate as you import from CD, go to the iTunes menu>Preferences, select the Importing tab, choose AAC or MP3 encoder in the "import using" selection box, then choose "Custom" in the "setting" box, and the window permitting bitrate selection will pop up. If you choose iTunes MP3 encoder, at least use VBR (variable bit rate) to maximize the sound quality. (VBR increases sample size as data complexity increases.)
If you would prefer LAME MP3's, fear not, for the easy-to-use CDex ripping software is a free download and requires only one simple extra step to get the files into iTunes for transfer to your iPod. Now if AAC sound quality is comparable to LAME MP3, you might wonder why you should even consider LAME: Because of portability to other devices. At present, hardly anything but iPods can read AAC's or Apple Lossless, but almost everything reads MP3's. So if you plan to burn CD's of your compressed files for playback on your home or car CD player (for instance), it would be wise to choose MP3.
One other consideration specific to the iPod- It has a 32MB cache (If you don't know what a cache is, read the last paragraph of this page: iPod + iPod Mini- Batteries). Keep individual file sizes below 25 MB as the rest of the 32 MB memory holds the iPod's Opperating System. If you choose a compression rate that results in large files (i.e. Lossless), then the cache won't hold very much 'music' and the hard drive will have to spin up frequently to fill it, and that will shorten your battery life somewhat.

IPv6 Addressing Point to Point Links in the enterprise

For an enterprise, it doesn't seem to make sense to use Global addressing for point to point, transit-only links and loopbacks.
Link-local only addressing breaks debugging tools like traceroute, DNS, etc.
Is Unique Local the correct choice for this?
I've searched quite a bit and I've not found a lot of discussion about scope selection for point to point links. Some RFCs such as 6164 imply Global scope vs Unique Local scope usage is a preference. Most discussions of point to point addressing focus on bit length. I'm assuming this means design concerns are agnostic toward scope selection.
Is anyone aware of documentation I've missed or have any recommendations in this area?
If ULA was the correct choice, address hierarchy might look like this:
DataNetwork1 -- Router1 -- ULA.1.1 -- Link -- ULA1.2 -- Agg Router -- Core
DataNetwork2 -- Router2 -- ULA.2.1 -- Link -- ULA2.2 -- Agg Router /
DataNetwork3 -- Router3 -- ULA.3.1 -- Link -- ULA3.2 -- Agg Router /
The network core would have summarized entries for DataNetwork[1|2|3] and ULA[1|2|3]. IE, there would be a Global hierarchy and a ULA hierarchy.

Scott,
Let me break this down into some categories for you.
Address selection:
I believe that best practice is to use Global Unicast Addressing everywhere (coupled with a proper security policy at your edge). ULA was a compromise for Site Local never being properly defined and whilst it can be used in the same way as GUA I don't believe it is worth it. Irrespective of what you use (GUA or ULA), subject to your security and routing policy traceroute will work from both ends (e.g. you tracing out, someone tracing in)
Address masking:
The general rule of thumb is that you allocate /64s to eveything and then mask down to the appropriate mask for the function you are expecting (P.S. Forget everything you learnt about IPv4 address conservation). If you are using /127 masks then in theory every p2p link in your network is either a 0 (::) or a 1 (::1)
e.g.
traceroute HostB:
1     2001:1234:abcd:1::1
2     2001:1234:abcd:2::1
3     2001:1234:abcd:3::1
4     2001::4:10
The only exception to this is loopbacks, you can sequentially allocate /128s from the same /64 block
NOTE: /127 support is recent and may not be supported by some vendors, in this case use /126 masking (same as you would use /30s in IPv4)
If you have a /48 ( a normal enterise allocation) or larger then this should not be an issue ( you have access to 65536 x /64s) the only reason you would consider ULA for infrastructure numbering is because you have a small IPv6 pool. I would still argue you should get more IPv6 addresses than use ULA.
I hope this helps
Cheers

MPLS vs Point-to-Point over Citrix Performance Difference

We run Citrix at our remote locations. We have two circuits at each location. One is a point to point for backup and the other is an MPLS circuit that is our primary. Both circuits are T-1 speeds.
We have all thin clients at our remote locations. When communication goes through the point to point circuit it utilizes much more bandwidth. Maybe 1.2 Mbps on average but when we communication through the MPLS circuit only 800 Kbps of bandwith is actually being used.
Can anyone explain this? I was thinking that maybe MPLS does a faster job of switching the packets across the WAN and that the Citrix does not need to use as much bandwidth because of this. This analyis was completed across all of our sites and in each case Citrix uses more bandwidth on a point-to-point vs an MPLS circuit. I have not had any users complain when accessing either ciruits.
What do you think is causing this?

Hi,
I fully agree with Swaroop. Being an instructor teaching many MPLS classes I was frequently confronted with the opinion MPLS is "faster" as it is "switching". This is not true and I always countered this - provocantly - stating that MPLS is reducing throughput, so it is slower! What I mean writing this: given a certain topology for IP forwarding and turning on MPLS on it will increase the overhead (additional overhead by adding labels) and thus reduce end to end IP throughput. The lookup is done by the same algorithm (CEF) at wire speeds for IPv4 and labeled packets - there is no speed gain for either technology.
Do not get me wrong, this does not mean MPLS is "bad" and in fact the difference between pure IPv4 forwarding and MPLS forwarding is marginal and most likely irrelevant for any real environment. The advantages of MPLS are plenty and thus a marginal throughput difference is not the most important thing to consider.
I guess the idea of "switching is faster than routing" stems from the fact that there were times, when IPv4 forwarding ("routing") was done in CPU, thus was slow, whereas L2 forwarding ("switching") was done in hardware and thus was faster. It dates back to those days where we used AGS+ (an old router, which is EOS, EOL and most likely even EOeBay ;-) and f.e. Cat5000.
Now coming back to the observed behaviour in the original post there might be some reasons to explain it:
1) different L2 overhead as pointed out by Swaroop, especially as I would assume rather small average packetsizes.
2) Additional traffic on the P2P link not sent through the MPLS cloud - check your routing, if it is exactly the same for both links.
3) Measurement artefacts - as Swaroop pointed out. Is the load interval the same for both interfaces? I would rather use a packet analyzer than only go for a "show interface" to get precise values.
Hope this helps!

Can I use my Time Capsule with a point to point antenna?

We have a building about 400 feet away that I would like to install wireless cameras. Can I use a point to point antenna with our time capsule or is there a better option?

The Time Capsule is too hard to get into. You can do this but the end result will be rather messy and for an expensive unit like the TC that is a waste.
Get a unit made for this job.. you only need a WAP..

Turns out the mistake was not adding a mask to the subnet. Ex:
Router_2(config_router)# network 192.168.0.0 0.0.255.255
Router_2(config_router)# network 172.27.0.0 0.0.255.255
Doing that on both routers made the hosts capable of pinging each other.
Thanks for the tips everyone

ITunes won't synch 80 songs at 128 kbps despite having 5.5 GB of space on iPod. iTunes or iPod error?

My 4th gen 30 GB iPod has 5.5 GB of space on it (this is what iTunes says before I hit sync). I want to add about 80 songs to be automatically downconverted to 128 kbps. When I try to update iPod, iTunes indicates iPod is overcapacity by over 19 GB and won't add new songs. Something is not right with either iTunes or iPod. Is anyone else having the same problem?
All I have is music on the iPod. No apps, no games, no movies, just music.
I just subscribed to iTunes Match. Could this be the reason why this is happening? Is anyone else having the same problem?

I'm having similar problems. Up until 4 May 2009 when I installed Windows 7 RC1 on it, I had one XP SP3 PC which was running iTunes properly and syncing and autofilling my iPod shuffle. The laptop described below no longer let me run or re-install itunes on it since I upgraded it to XP SP3. When I switched to Windows 7 RC1 on the XP desktop that was running iTunes properly, I was able to re-authorize that PC for iTunes 8.1 (64 bit) but after that, could not sync nor autofill, nor restore the ipod, but I could buy songs and play all my songs under Windows 7 RC1. Yesterday (Friday 15 May 2009) I got a new HP Compaq 6735s 2 GB RAM 160 MB HD, Vista Home Basic laptop and today installed a fresh download of iTunes 8.1 on it. Now that laptop won't let me even authorize iTunes on it. Any time I do anything in iTunes that involves contacting the web, it comes back with unknown error -3212 unable to contact server. This comes up when I try to authorize, and when I try to play some of my purchased songs on the laptop -- it demands that I authorize the laptop then tells me I can't (error -3212). Also when I try to restore the ipod, I get the same -3212 error trying to get to the update server. I turned off both the windows firewall and stopped the McAfee firewall but that didn't help. I renamed the Hosts file also without result. There doesn't appear to be a tech support email address or trouble reporting web form that can be used to report this and the search and troubleshooting FAQs on the itunes website seem to be pretty useless in resolving this. The phone numbers are either sales related or they want $59 an incident to give me a call back. Seems like Apple is drifting into the Yahoo and Google approach to tech support -- basically, "discuss your problems among yourselves, suckers, we're too busy raking in the cash to bother with your problems."

How do I get routing data from the Map App (powered by TomTom) so I can display the point-to-point annotations (turn-by-turn navigation) without leaving my own application.

I have a tableView displaying a list of contacts from a Cloud Database. After selecting a contact, I push to a programmatically created MKMapView. Then I display the initial region (the view) that includes the users current location (starting point) and their selected destination (end point).
Now I want to display annotations (as described in the Location Awareness Programming Guide) that displays polylines which will represent the turn-by-turn navigation IN MY OWN APPLICATION, and not in the Map App currently used in IOS6.
Due to licensing and its becoming depricated in IOS 6, I do not want to get routing data from the Google Maps API. How do I get routing data from the IOS 6 Map App (powered by TomTom) so I can display the point-to-point annotations (turn-by-turn navigation) without leaving my own application?
I checked out Stack Overflow and other forums which basically left me with the impression that this is not possible. I also checked out the TomTom iPhone Mobile SDK User Guide from the TomTom Developer Portal and am still confused. It must be possible to retrieve routes, since the Map App can display turn-by-turn directions. How can I retrieve turn-by-turn data that I may display as a route within my own application?

Thanks Michael. Apologies for the slow reply I was away for a bit (holiday blitz at work and visiting family madness etc.etc.) back now, I set both options you requested to "never " and retried the CMS software with no change.
I do have progress of a sort though, as a test I took a separate test PC and put a clean install of Win7 on and loaded up the CMS software (it worked perfectly) and then took the version of ole32.dll off that machine and put it onto the computer I had built
for her (using Linux) and...
got a new error code. Darn I was so sure I had found a clever solution this time lol.
Anyway now when the CMS fails it gives me a similar error but the offending module is "ntdll.dll" sooo... I tried taking the "working" version of ntdll.dll from the test box and moving it over (making sure to back up the existing ones
first so I could put them back if needed) to her new PC and the PC would not boot.
It seems to want the original versions of a few Dynamic Link Libraries and if I could somehow give it those while not breaking Win7 it should theoretically work seeing as it no longer errors with ole32.dll.
ntdll.dll however seems necessary for Win7 to boot.
So what I am wondering now is:
Is there some way to have both versions of the DLL file in the system32 folder (bypassing the "cannot have two files with the exact same name in the same folder" thing) or rename the original DLL's something else and somehow make the CMS look for
the new named versions so the system has the updated DLL's it needs to boot/run and the CMS has the old ones it wants to run or is there someway to have a self contained install of the CMS, say on a USB flash drive and give it it's own E:/windows/system32/needed
dll's path to the files it needs?
Willing to try any other options or settings you may have come up with as well.
Thanks again for your reply and my apologies for not answering sooner.

I'm trying to set up a system where I can send point to point messages via sockets to certain ips, send broadcast messages to every pc in the network, and also be able to listen for point to point messages and broadcast messages, all in the same port. I've been able to establish a point to point connection using the Socket class to send the message, and using the ServerSocket class to listen for messages, but I can't seem to get broadcasting to work.
I read somewhere that for broadcasting one should use the DatagramSocket class. The problem is i'm not sure which ip i'm supposed to specify when I send the message. Also, do I need a special listener to listen for broadcast messages, or will the ServerSocket listener work for that?
This is what I have for the broadcasting part:
String msg = myId;
DatagramSocket sendSocket;
sendSocket = new DatagramSocket(Constants.COM_PORT); // 4567
InetAddress group = InetAddress.getByName(Constants.BROADCAST_ADDR); // "192.168.1.1"
DatagramPacket dp = new DatagramPacket(msg.getBytes(), msg.getBytes().length, group, Constants.COM_PORT);
sendSocket.send(dp);
sendSocket.close();
Thanks in advance

It worth mentioning that UDP/broadcast and robust do go together easily.
- UDP does not guarantee delivery. i.e. messages can be dropped and you won't be told. Lost packets are not retransmitted either.
- UDP can fragment packets if larger than 532 bytes long.
- UDP packets can arrive out of order (though I have never seen this myself)
If your receiver is under load/busy it can miss many packets if its buffers overflow.

Calculating BPM using either Peak Detection point by point or FFT

Hi Guys
Im new to Labview and have absolutely no idea on programming and stuff. Im doing a project on Heart Rate monitor.
I'm using labview to read the analog input to an Arduino Mini. In my attached VI im using Peak Detection Point by point to calculate the BPM but it doesnt seem to work. I took references from several VIs to arrive at my VI.
My instructor told me I could try using FFT to calculate the BPM as well but Im not sure how to carry it out in Labview.
Hope you guys can help me with this.
Thanks alot!

Ok, we have some problems here.
1. The Data Bits property is the number bits for a single character that is being transmitted. You should not use that. Since you are using an Arduino, it should be sending the termination character. So just tell the VISA Read to read maximum number of bytes you expect from a single message or just some large number (like 25). The VISA Read will stop reading the port when it encounters the termination character.
2. The String Subset is not doing anything. Just remove it.
3. You should move your Wait to be outside of the case structure. As is currently written, if you are not taking readings you will use up all of your CPU.
4. You should have labels for all of your controls and indicators.
5. Your time calculation is completely wrong. You want to subtract the time of the previous peak from the current peak. I recommend you use a Feedback Node to do this.
Here's a slightly cleaned up version of your code.

XY graph : Plot point by point

hi my intention is to plot in a XY graph point by point. Meaning for eg: I want to plot a scatter plot.
First I check if the array element satisfies a certain condition (let's say if it lies between 1 to 5) if So I want to plot in red color, else I want to check another condition (let's say lies between 5 to 10) and then plot in blue color and so on.
First I check for the condition and link it to a case structure such that each case structure will contain the corresponding plot color but it doesnt seem to be working.
Kindly guide me with this.
thanks!!
Solved!
Go to Solution.

Hi Chathuri,
If you want to plot a scatter plot, you can do this by editing the properties of the XY graph. Righ-click on the X-Y Graph object and click on Properties.This will bring up the property viewer. If you then go to the Plots tab, you should see a screen similar to the one shown as an attachement. The fourth column from the left sets the display type and if you click the top diagram, you will display individual data points. I have circled this in the attached diagram. You will also need to set the tick markers to display. You can do this if you set the third column from the left.
Hope this helps,

Hi, I'm trying to convert my music to 128 kbps AAC, How do I do that?? Thank you

Hi, I'm trying to convert my music to 128 kbps AAC, How do I do that?? Thank you

Hi Dawn,
Open iTunes and select preferences under the itunes menu. under the General tab look for import settings. Select AAC as the encoder and 128kbs. then open your main iTunes window and select some music you want to convert, then look under the advanced menu and one of the options should say create AAC version. Andor if your sending music to an iphone or iPod there is anoption in the device preferences that will do the same thing.

Change the convert to 128 kbps before transferring to iPhone option?

iTunes gives you the option to convert all higher-bitrate audio to 128 kbps AACs before transferring to my iPhone. Great, except I'd prefer a little higher quality. Is there any way to make it, say, covert to 192 kbps VBR AACs instead?

if you're converting from a lossless format, you could use this:
[_*Lossless to AAC Workflow v2.2*_|http://dougscripts.com/itunes/scripts/ss.php?sp=losslessaccworkflow]
Two scripts assist with importing/managing Apple Lossless or AIFF audio files and sending converted AAC copies to a mounted iPod set to "manually manage songs and videos".
*Lossless to AAC Workflow (CD->iPod):*
Imports each enabled CD track as an Apple Lossless or AIFF file
Makes a converted AAC copy of each imported file
Adds the AAC file to iPod, deleting the original AAC from iTunes.
*Lossless to AAC Workflow (iTunes->iPod):*
Makes a converted AAC copy of each Apple Lossless or AIFF track selected in iTunes
Adds the AAC file to iPod, deleting the original AAC from iTunes.
In this way you can keep archived lossless files on your hard drive, and manageable AAC files on your iPod.
+Yes, iTunes 9.1 will auto-encode tracks to iPod, but only 128 kbps AAC; these scripts enable use of your Custom AAC encoder setting.+
