How to build a redundant fiber optic ring

Hello everyone. I would like to connect 10 buildings with a redundant fiber optic ring and have a control to connect to the closet room build you on the ring to receive data from our process control systems located in the buildings of the ring. These are domain controllers systems that feed information to the bacbone on FTES. Can someone tell me a document that shows what I have to do and an example of architecture. We use S Catalyst 2960 switches or do I me 3750 s in all my buildings. Thanks in advance for any help.

Hi Carroll,

as L2 VLAN and VRF on L3 suggested donation is the best option to go with multiple isolated logical networks on a physical network

Take a look at the link design guide for the isolation of path by using virtual and VRF LANs which below is very useful

hope this helps

  • 55VL900A and BDX4300KY - TV is not output Dolby Digital fiber optic

    Just installed my new TV, 55VL900A - great picture, very happy. I have a BDX4300KY a drive blueray and Foxtel connected to the TV via HDMI.

    The TV has audio output optical fiber, which I run for my Yamaha DSP - A1 amp.

    The Blueray and Foxtel are defined to pass on Dolby Digital through HDMI.

    Problem 1: TV does not have Dolby Digital of the fiber optic connection.

    Problem 2: If I run audio blueray or foxtel fiber optics directly to my amp, there is a sync problem. The audio is delivered earlier than the image.

    I searched and found no results in my manual, or in the forum. Help, please.

    Thank you, Mike.

    Hello

    I put t have the same devices at home, but I use the optical cable for sound. It is connected to my blue ray and Technichs amp player. I use 5.1 home theater connected to the Technics. The sound is perfect.

    I put t know how it works on TV Toshiba but check please if something should be enabled there.
    > The TV does not have Dolby Digital of the fiber optic connection.
    See s operating manuals and do not forget the optical output must not be activated. Optical cable is connected to the amp in the optical port marked as TV in the back? Don't forget that bulks is set to TV chanel when you want to hear the sound of the TV directly. In my opinion, it should be best option for you if you will be able to make it work.
    > If I run audio blueray or foxtel fiber optics directly to my amp, there is a sync problem. The audio is delivered earlier than the image.
    Which is really strange. Can you please test it with cable audio normal cinch? It will be interesting to know if the same problem occurs again.

  • I have an iPhone 6 and use Verizon as my server. How can I increase the number of rings until it goes to voicemail?

    I have an iPhone 6 and use Verizon as my server. How can I increase the number of rings until it go to voicemail?

    You can not. There is no adjustment to make on a phone. In fact, it is not based on the number of rings, it is a problem of synchronization based on the parameters of the call. You can contact Verizon to see if they can increase at that time here, but even if they can, it won't be much, only a few seconds if they do at all.

  • How to build a table of TDMS file open

    Hello

    Examples NI TDMS - Express write data .vi (time domain), I can build a PDM file with 2 channels (sine and square waveforms) data, which are stored as test.tdms.

    Using Express read .vi data (time domain), 2 channels of waveform data are read. How to build a table later? How to separate the 2 channels of data in the tables 1-2 and manipulate the data using table functions?

    For example,.

    I want to collect 100 from index100 between channel 0 and their average. I want to take 50 samples from the channel 50 1 index and double each element.

    Thank you for your help.

    Bing@NCL

    Hey Bing.

    You can perform operations on different channels in the 2D table using the table to index. This will allow you to choose the channel to operate on, then you can perform the operation inside a loop on each element. In the included code snippet, I used a shift register to find the total cumulative values in channel 0 and then divided by the number of samples.

    I recommend you read some tutorials LabVIEW and bases of knowledge on topics that are related to yours. These could help a lot.

    I hope that my suggestions help,

  • fiber optical sensor su19 110 115 a 126 vs nor usb 6008

    Hi expert... I am looking for idea or help on my project. I try to get the measure of mention nor USB 6008 sensor output. In fact, I'm new with nor peripheral usb n still study n the search on internet or n. forums I found an idea to connect the sensor by aoi, but I can't seem to get a measurement any. Is the sensor can connect directly to the device usb or need some custom wire diagram between them. Thanks in advance

    First of all, it is useful if you name the manufacturer of the sensor. A single part number means nothing to most of us.  You use the sensor fiber-optic Pepperl + Fuchs? Even better is to display the technical/manual plug of the sensor or links to them.

    The data sheet that I found for the sensor to Pepperl + Fuchs is not very well written, in my opinion. It seems that the outputs are impulses with dependent amplitudes of the voltage and the frequency or the timetable set by the mode of operation.

    If it's the device you use, the only way you have any possibility to decode the outputs with the USB-6008 box is to measure with an analog input and then process the data in the software. According to the supply voltage, you will probably need a voltage divider to reduce the output voltage of the sensor to a level compatible with the DAQ hardware.  You also won't be able to use the high speed of the probe because the heart rate exceeds the Nyquist limit. In standard mode, you mighte be OK, but you can use a single channel of the USB-6008 to stay in the Nyquist limit.

    Hello

    To bookmark this site.  He may have more information for you. Wikipedia

    Joining lengths of optical fiber is more complex than to join the electric wire or cable. The ends of the fibers must be carefully cleavedand then spliced, either mechanically or by merging with heat. Fiber optic connectors for removable connections are also available.

    Unfortunately you cannot use the series of development because it requires "version 1.11.0 and require a compatible for most C ++ 11 3.1 Clang compiler or GCC 4.7.

    1.10 stable series should be ok.

  • Why use fiber optics?

    Why use fiber optics?

    There are two main reasons that the fiber is used.

    1. it's faster (as above) because it uses light to transmit data instead of electrical impulses.

    2. you can run fiber a greater distance as you can in copper based media. A fiber run can go up to five miles before it needs of a Repeater.

  • How does ACS check redundancy?

    Hello

    In a router, if you configure the RADIUS server, Ganymede-1 host Ganymede-2, this is how you configure the redundancy of the ACS.  My question is, how does the router check the pulse of each RADIUS server?  By ping or another keepalive mechanism?  What this command do really behind the scene?

    What is happening in our environment, is that Ganymede-1 in Windows services keep stops by itself.  We cannot authenticate and Ganymede service does not switch to Ganymede-2.

    Hi Ganesh.H,

    Thanks for the reply.  Looking at the command documentation, it states:

    "If the command is not configured, the timeout interval is 5 seconds."

    So it is default configured regardless I enter this command or not. However, this command does not work as TACACS service does not fail over.  Any other idea?

    Kevin,

    This command is not by default configured in cisco swithces the default setting is 5 seconds if you configure timeout Server tacas only without sepcifying the time in sec.
