    Question How can I troubleshoot IP Console and Gateway Audio Transport across a network?   Answer On initial set up of a console system, often the most frequent problem is the failure of Consoles and IP-223s to communicate across the network.  Common causes of this are: Typos in addressing, such as multicast addresses and port numbers not matching on end to end devices. Firewall turned "ON" in console computers Multicast being blocked across the network due to router settings, etc Use of the Telex “VU Meter” program (download at http://www.telex.com/us/dispatch/file?i=97544&lg=eng) is an excellent and quick way to determine if data is present on the correct port numbers. Open VU Meter with the appropriate multicast address and port number entered in the blanks. Turn the program on. Send a test call on the TX or RX port numbers and see if VU Meter indicates digital audio activity. You may open multiple instances of VU Meter to simultaneously monitor TX and RX port numbers.  Verification that audio data is being sent out on the correct address, but not arriving at the far end of the network may indicate a problem with network configurations, that is, blocking of multicast traffic. Please note that some newer switches are intelligent enough to contain routing functions, which can be unintentionally enabled in some situations.           © Copyright Bosch Security Systems All rights reserved.

    Question Multicast doesn't seem to be working on my Telex Dispatch system - What are good next steps to troubleshoot for possible network issues?   Answer The problem can come from many reasons, the two most common are the following: 1. The TTL value entered isn't high enough for the number of router hops and Multicast packets are being pruned by the network before reaching the end point unit.  Try increasing the TTL value. 2. By default WAN or Layer 3 networks will not pass multicast traffic, a good next step to test overall port number addressing.  Configure a number of devices for "point to point" Unicast instead of "point to multi-point" Multicast: Enter the IP address of the far end IP unit into the Multicast address field of the local IP unit.  Do this for both ends. If console and radio traffic now work using Unicast the network is not configured correctly for Multicast traffic and you need to work with the IT manager for resolution.          . © Copyright Bosch Security Systems All rights reserved.

    Question What does Dispatch products due in the cases of missed packets (lost due to jitter or errors)?   Answer The products have a jitter buffer that allows for packets to be reordered if delivered out of sequence, if this buffer empties due to lost packets the unit will stop and restart once the "Packet delay before playback" buffer is filled.    The product looks at the source and destination address, when a correct incoming port number is recognized the unit will lock in on that source address and ignore packets coming from another source address until the first source stops sending then the second source has access. There is no protection against multiple packets from the same source address with the same multicast and port numbers as this shouldn't happen.  Add to this the same sequence bit in the packet (echoes) should never be allowed. Packets not received or lost before their play sequence (bit) time in the buffer are lost and next packets in the buffer pulled in.             © Copyright Bosch Security Systems All rights reserved.

    Question How do I update Telex Dispatch IP products with Telex System Manager?   Answer The Firmware Update Tool window, shown in Figure 6, is capable of updating the firmware on the IP-223, IP-2002, IP-1616,C-6200, NEO-10, ADHB-4 and IP-224 devices. To open the firmware update tool window, do the following: > From the Tools menu, select Firmware Update. The Firmware Update Tool window appears. Firmware File Info Group Box The Firmware File Info group box is used to display the information about selected firmware files. Destination Group Box The Destination group box is used to display the device to which you want to update the firmware. From the Destination list, select the device to which you want to update the firmware. NOTE: Multiple devices’ firmware can be updated in parallel by selecting multiple devices from the Destination Device List. To select multiple destination devices, hold the Ctrl or Shift key on the keyboard and click on each additional device in the Destination Device List. Manual Entry Group Box The Manual Entry group box is used to display a device’s IP address that does not appear in the destination list. NOTE: All devices appearing in Device List with a matching device type appear in the Firmware Update window’s Destination list. If a desired device does not appear in the Destination list, you can enter the device’s IP Address manually using the Manual Entry field. Once an IP Address is entered into the IP text box, you need to push the green plus button. The IP Address just entered is added to the Destination List, and is then selectable as a destination. Multiple destinations can be manually entered in this way. Login Group Box The Login group box is used to enter a user name and password. In the Password field, enter an appropriate password. NOTE: In order to update a devices’ firmware, proper credentials must be entered. The Firmware Update tool first attempts to use the password specified. If the credentials are invalid, a prompt is displayed asking for new credentials. This is useful when updating firmware to multiple devices with different admin account passwords. To update the firmware on a network device, do the following:       1. Click the browse icon to navigate to the folder where the firmware file is stored.       2. Select the firmware file.            Once a file is selected, information about the selected firmware files appear in the Firmware File Info Group Box. NOTE: If you have already accessed the firmware file, and established the location, you can use the drop down menu to select previously established file location.      3. Click Write Firmware           The Firmware Update Tool window appears listing all selected devices, a progress bar, and up-to-date status  information for each device.           © Copyright Bosch Security Systems All rights reserved.
