Is the IP over DWDM solution standardlized?

Because if this solution is not standardlized, the carriers cannot accept this solution--IP direct over DWDM without OTU board.
Not standardlized means absolutely monopolization. So the carriers are not fool.

I dont consider myself an expert on this topic or any other my knowledge is like few drops of the oceans so lot more to learn.
I dont think so, this is just why I opened this discussion, because, you know, no vendor would like to compliant with CRS-1 DWDM interface, OTU is the most value of the transport network. and different DWDM has different encoding method.
My optical knowledge tells me(i can be wrong) that if CRS-1 G.709 module need to be transposted over any other vendor DWDM system AND if the siganl is NOT 3R regenrated (means you are not using the transponder of other vendor)it it either going through a Optical Amplifier or Dispersion module. Then i dont think these different encoding method is considered by these modules.
These different encoding techniques(I think you are talking about FEC & Enhanced FEC ) are important when you are sending it over a distance when it undergo 3R regeneration.
Something like Crs-1 (G709 card)-Other Vendor (Optical MUx, Optical Amplifier etc NO Transposnder) -CRS-1 (G.709Card ) a setup which i think is not dependent on what encoding is being used.
Forexample here Cisco CRS-1 is implemented with Ciena Optical Transposrt. (I dont know the validity of this deployment as i know things are different when you want to deploy these solutions)

How to persuade the carriers choose the solution of IP over DWDM?

Hi,every one.
why IP over DWDM(15454) is the correct choice for carrier class service?
why the router can instead of SDH/OCS?
Except of save the client interface between DWDM and Router, What other advantages?
Best regard!

1. SDH can also provide you carrier class service, IP over DWDM is right choice if you have too many wavelengths from one point to another (not sub wavelength). You reduce your cost as removing layers.
SDH is right choice when you need subwavelngth kind of capacity between nodes as DWDM crossconnect are not as good as SDH crossconnect.
2. Why router because you are removing the SDH layer.
3. Apart from saving SDH boxes IP over DWDM also will be less complex in troubleshooting. If your router is working fine then problem is in DWDM layer. If you have IP/SDH/DWDM then it is comples to isolate problem.
I think IP over DWDM are still in early stages as is rigid kind of network even with today WXC. Need a totally different kind of wavelength crossconnect to see all the benfits of IP over DWDM.

It's now over 6 weeks since I made the mistake of updating my iPad and I am furious and frustrated at the lack of a solution to the problem with ios 5 audio app missing lyrics

It’s now over 6 weeks since I made the mistake of updating my iPad and I am furious and frustrated at the lack of a solution to the problem with ios 5.
I recently updated to ios 5.1 but nothing has been done to rectify the audio app problems ie lyrics no longer shown,
I am extremely disappointed and angrywith those responsible for the iOS 5 update, in regard to the way it hasaffected the music app in my iPad.
I also own an iPhone 4, am an avid Apple fan, and up until now have beenextremely pleased with the devices, and have sung their praises to friends andassociates.
I am a professional musician, and purchased an iPad primarily to use with theperformance of my music.
The changes made to the music app affected my performances over the weekendextremely adversely – limiting my repertoire and causing confusion and delays.
I have spent many hours talking withApple helpline assistants (who, incidentally have been very good and have triedto help), and I have also spent a lot of time on this letter.
I greatly regret updating to iOS 5.
There are two major problems with the music app.
1. Lyrics no longer displayed
2. Layout, and appearance and consequently performance have seriouslyregressed.
I have a repertoire of around 500 song backing tracks, organised into about 20playlists, half of which featured lyrics / chords that I have spent monthsrecently entering into iTunes so that they could be used on my iPad.
These were working fine up until the update - now they are gone.
Previously, the app featured large icons for playlist, artists, songs etc. atbottom of page: Now there are small, grey, indistinct barely legible buttons.
Previously, when playlist icon was selected - all the playlists were listedclearly in order on the left hand side in black on white (as in iTunes).
Now they are scattered across the whole page in large squares (displayingnothing if there is no album art).
The identifying wording below eachsquare is now small, grey, indistinct & barely legible.
Previously, when a playlist was selected - the songs were displayed in adescending list in black & white: now they appear as small, grey indistinct & barely legible.
Previously, when a song was selected - it appeared filling the page, and withaudio controls clearly positioned at top of screen. One tap would bring uplyrics.
Now audio controls appear at top once again small, grey, indistinct &barely legible.
A small square representsalbum art which if tapped fills page. A further tap fails to bring up lyrics.

Lyrics aren't supported in the Music app on iOS 5 on the iPad. These are user-to-user forums, they are not monitored by Apple (there are too many forums/threads/messages for that to happen). If you want to leave feedback for Apple then you can do so here : http://www.apple.com/feedback/ipad.html

IP over OTN or IP over DWDM?

these are two main trend in IP core Network construction.
The core different between them is how to dealing with the TDM service or other small granularity service in electrical layer. in Router or in OTN?
What is your opinion? I find many expert or communication fancier here, so beg your answers.

The core different between them is how to dealing with the TDM service or other small granularity service in electrical layer. in Router or in OTN?
As per my knowledge, difference between IP over DWDM or IP over OTN is which method can take all type of traffic (voice, data, video etc ) in efficient way not just TDM service or granularity (ROuter cannot beat SONET/SDH boxes in handling TDM traffic).
Most of the traffic now a days is IP not TDM, whereas OTN are good for TDM
Question is what can take packet effieciently without too many layers in between. Whether to add IP feature to OTN or Transport feature to Router.
I have no answer who will win IP in router or OTN but IP over DWDM (In router ) will not be the best solution. This method is good for point to point High speed connection things will change if you have lot of traffic to crossconnect.
In other post you have question that how can you separate traffic on different wavelngths, what do you think will your router will act as a crossconnect to segregate different traffic or what if you need only 5 Gig to point A and 5 Gig to point B will the router grrom that traffic?

Extending SAN - Native FC over DWDM Experiences

We are in the process of adding a new Data Center which will be geographically located about 60 miles from our existing Data Center, the solution I'm proposing for continuous SAN access and replication is deploying a DWDM solution (Ciena or Cisco) to be able to extend native Fiber Channel to the new Data Center which will provide for an easier and staged migration. My only concern is latency over DWDM for FC since the distance is about 60 miles, does anyone have a real life experience or have been through this type of deployment and can provide me with some feedback, advice, "what to look for" etc, will the distance be an issue using DWDM? I appreciate your responses, thank you.

A bit late but hopefully not too late to be useful.
I have two remote Data Centers thanks to a merger. Both are less than 6 miles by car and we have two paths to each of them. Both the second paths are about 34 miles in a wild ring thanks to a very important customer down south.
Our network engineer who controls the ONS doesn't have a clue about FC and has a bad attitude to boot. IP doesn't have any problems with latency but he had no idea about the SAN and latency.
I found he had somehow or another got 1 out of the four paths to go down the long link and the other 3 were using the short link. Our sync HDS True Copy got very upset about this and I could not work out why. We were getting terrible timeouts of about 300 ms. This bought down a couple of mission critical apps that relied on response times of less than about 20 ms. They would not write to disk at the remote size in enough time. We worked the problem out after a bit of yelling at each other. Now he knows to always use both paths if he fails them over and to actually let me know he is doing something. To be fair, the Brocade switches also sharing the links identified the link distance mismatch.
Another issue was turning on In Order Delivery for the mainframe. That should not be mixed with other general traffic. HDS are also (quitely) adamant that you should not mix sync and async from the same ports on the storage. I had to seperate them so we have one pair for sycn and another pair for async. It looks like a SAN problem but its the different writing patterns for sync and asnyc.
60 miles is too long for HDS sync TC. I believe there is an unwritten law that 32 to 34 miles is the longest to use for sync TC. Async is not a problem. I have not used any FC accelerators. I also have EMC arrays and I have no replication issues with them either.
When I first set up the native FC over ONS, I did a fair bit of measuring and testing. Our Exchange geo cluster using sync TC normally ran at about 5 ms response times down both paths. Thats a write to the remote Data Centre and then a write to the storage on site. Heavy work showed about 10 to 12 ms. MS suggest anything less than 20 ms. 32 miles is about 0.5 of a ms extra for latency so I never actually noticed any difference with either path.
I did a lot of async tc to keep replica's of important systems offsite and once all the fine points were worked out, it was a great solution.
60 miles could be 160 using the other path.
I have not tried FCIP but I believe there are no issues with it if the IP latency is acceptable.
Balancing of backups is a pain. The backup system might have 10 tape drives available and they will use the ones on one path and nothing on the other path. That causes congestion and slow response.. blah.. blah.. They don't care. Also, use a port channel as you need two ISL's..
NEVER tell anyone that your ISL's are over distance unless you absolutely have too. Companies will always blame that. I have a mixture of Brocade and Cisco switches using the ONS. I had a problem with my Brocade fabric and Brocade immediately stopped working on the problem as they blamed the ONS for creating timeouts, etc.. etc.. It had nothing to do with it but you see what I am saying.

Saw this solution on another post about an iPad in a school enviroment. Might work on your iPad so you won't lose everything.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.

My ATV gen 2 won't connect to the internet over a wireless BT home hub 5 network

My ATV gen 2 won't connect to the internet over a wireless BT home hub 5 network. I've recently upgraded to a BT HH5 and now I cannot airplay with my 2011-MBP, and the ATV will not connect to the iTunes store or software update.

Ok, thanks (not sure I know what you mean!). I have seen a solution that tells me to rename the two SSID's? Is that what you mean? All my devices are wireless, and all can connect to the internet except the Apple TV. Now I have disabled the 5GHz channel all devices are on the 2.4GHz channel and all work fine, including the Apple TV and airplay between my MBP and ATV.

Lost the voice over bt function after removing battery

I have a new Treo 800w and a new Plantronics 925 bt headset. I installed the voice over bt software, established a connection, and was able to use it to make voice calls (call john smith). I removed the battery to record serial numbers etc. When the Treo came back on, I reinstalled the voice software as advised. Now I can answer calls and talk using the headset, but I cannot get the voice commands to work again. I have not installed any third party software. Any suggestions?

Not sure why you re-installed the software again after a soft reset. Taking out the battery and re-inserting the battery is a soft reset. See the instructions in the article below for the hard reset procedure.
The program may have gotten corrupted when you installed over the top of the existing installiation.
Here is the statement from the download page regarding re-installing the patch.Effect of resets on this softwareIf you install the Voice Dialing over Bluetooth Download and perform a hard reset, you will need to re-install the Voice Dialing over Bluetooth Download.
If you install the Voice Dialing over Bluetooth Download and perform a soft reset, no action is necessary. The Voice Dialing over Bluetooth Download remains installed after a Soft Reset.
You may need to uninstall the program and re-install. The fastest way is to Hard reset the Treo and then re-install. the hard reset will erase all data on the Treo, so make sure you sync before hard resetting.

Wireless sync option not available on Itunes 10.5. After updating my iphone to IOS 5, the "sync over wifi" option is not being displayed in itunes.

hi, I managed to update both Itunes and my ios to the latest versions (10.5 and 5 respectively). I'm unable to see the "Sync over wifi" option in itunes. Can anyone help?

Maybe that's why I got lucky? I have 10.7.2. I have to tell you howeer that I did not check any check box in settings on the Notebook to enable Wifi sync, or in iTunes on the notebook. I did have options when setting up the iPad and I selected sync with computer rather than back up to cloud. Maybe that is another difference? I feel feel fortunate that as I type this my iPad is syncing over wifi and you're all having trouble.
Just to confirm I have iTunes 10.5 MacOSX 10.7.2 and iOS5 installed on the iPad. I'm going to dive in and do the phone now too. I will report any troubles, or pay more careful attention when the iCloud settings and set up come on the screen. Maybe I did something else I don't remember.

MAC Voice Over: Why does the screen view lag behind the voice over audio?

MAC Mac OS X 10.6.8 (10K549)
When using voice over on a MAC with DE 1.8 - most times when paging thru a pdf file/book the voice and the view are inconsistent. When using VO - moving to the next page with the right arrow key - the audio starts to read the next page (correct), but the display is one page behind (not correct). For readers - especially those that have significant visual impairment - this will not work for them. Is this a defect - and if so - I would be very happy to re-test this feature if a new revision of DE 1.8 is provided.
I am unsure this is the correct forum to raise issues such as this one. I am in the process of evaluating Adobe DE 1.8 - my sister is blind and I am trying to move her to a MAC with VO. I really appreciate Adobe's effort in supporting JAWS and MAC VO - thank you on behalf of all disabled folks out there.
Below is a detailed list of steps to re-produce this audio/screen inconsistency issue.
- Install DE 1.8 and add to the dock
- Add a pdf file/book to DE 1.8. For my issue, I am adding the "Voice Over Getting Started" guide.
- Turn on Voice Over - Cmd+F5
- Using VO - Go to the dock and select DE and start it. The "Last Read Book" typically is the focus for the VO cursor. Then using VO next item (VO+right arrow) - move the VO cursor to "Library Content Table". This is the list of books that are displayed in DE.
- Using the up/down keyboard arrows - move up and down thru the books in the content list. At this point - you should already see that the VO audio announcing the title of a book is not synchronized with the row in the table that is displayed. The voice is announcing a book that you selected, but the display is showing the previous book.
- Once you hear (not see) the book you want to test with, hit <enter>. DE will open the book and start to read using VO. At this point the screen and audio for the first page in the book are the same.
- Once the book has been opened by DE - Using the right arrow key navigate to the next page in the pdf/book. Normally the right arrow key is the short cut to allow a user to move forward or backwards thru a book, one page at a time.
- With DE and VO - what happens is that VO responds to the right arrow key and starts to read the next page. But the screen is still showing the previous page. Hence the screen and the VO audio are out of sync.
- For anyone that uses MAC VO - this will prevent them from using Adobe DE 1.8.
If I am doing something incorrect - please let me know. If you need any assistance or further information regarding this issue - please email me.
Best Regards
Mike R

hi, Mike R:
Thanks for your information. We have tested several Mac machines, iMac and MBP (use the same version as yours). But we can't reproduce the issue. Actually working with VoiceOver is a fundamental request for our application, we did test them before releasing the build.
We suggest you test other applications, e.g. Finder, Preview and iTunes, to make sure if VoiceOver works fine with them. Or can you please check if your VoiceOver settings are correct?

You should be able to use the battery if you get a car type charger which recharges mobile devices.
The full size iPads use a 10-12W charger, whereas the mini uses a 5W charger. Many car chargers only supply 5W. But at 5W, the car charger should give you some extra time on your iPad. It would be best to use a 10-12W car charger.
