Critical Communications: Dispatch

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   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   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   Can I connect a secondary power source to the Dispatch console?   Answer   The Dispatch consoles have an Auxiliary Power connector and a primary power supply connector on the rear of the unit. These connectors are internally connected but not designed to supply power to the unit at the same time (either one but not both at the same time). If both sources are required a switch must be implemented on the backup power source requiring a manual switch over from primary to the backup source if the primary power source fails. Power should not be supplied simultaneously to both connectors as hum and noise could be introduced. When primary power is restored, the switch should then be returned to the normal position.                 © Copyright Bosch Security Systems All rights reserved.
