  • Page 11: About This User Manual

    About this User Manual This User Manual describes the essential functionality, installation and configuration of your V200 unit. It also contains a great deal of reference material, which you may need when fine tuning your unit for a particular application.

  • Page 12: Structure

    This User Manual describes only the software functionality active in your V200, or which can be enabled by Feature Keys on your unit. If you are configuring a variety of Vocality products you may find our generic VOS User Manual helpful.

  • Page 13: Symbols Used In This Manual

     Symbols used in this manual Some items are only relevant when your V200 is used to talk to another Vocality device. Where a feature is dependent on your V200 connecting to another Vocality device the following icon is shown: Some features are only unlocked by the purchase of Feature Keys or the purchase of certain hardware options.

    Valid for V08_08.02 or V08_48.02 About User Manuals The accuracy and clarity of our User Manuals is important to us at Vocality. If you find an error or have any queries which are not answered by our current documentation, your local Vocality support team would be happy to hear from you.

  • Page 17: Functionality

    Your V200 is a powerful systems multiplexer which adds density, scalability, and redundancy to the portfolio of Vocality products. It is not only conceived as a flagship unit that will support legacy V100/V50 networks but more strategically as a unit that will reliably perform as the hub of a mission-critical network.

  • Page 18: Capabilities

    The V200 also provides hot-swap capabilities such that line cards can be added or older cards to be replaced without affecting the networks connected to the cards in the remaining bays.

  • Page 19: Cpu Card

    At least one CPU card must be installed in each V200 – it is configured as Slot 0 and provides the management facilities for the entire unit. Another CPU card may be present and assigned as a redundant Slot 0 CPU card –...

  • Page 20: Alarm Port

    A UDP relay function enhances this by allowing communication between a remote client and a server on the home network. Users can plug their laptop into the remote V200 and log in to their home network, surf the internet and pick up E- mail.

  • Page 21: Call Routing

    All synchronous data channels configured with a DBA clock source are assigned to this pool, which is distributed between streams in proportion to their bit rate. Your V200 smoothly adjusts the clock speeds on all DBA ports whenever there is a change.

  • Page 22: Redundancy And Hot-Swap

    2.2.5 Redundancy and Hot-swap The V200 chassis and service cards are designed to provide years of reliable operation for mission-critical networks. To augment the basic robustness, all cards, including even the PSU, may be operated in pairs to provide a hot-standby for essential services. This is...

  • Page 23: Network Topologies

    The ability to configure multiple aggregate ports allows a vast range of topologies to be built with the V200, ranging from simple point-to-point systems at one extreme to a Star network cluster with a large number of remotes at the other. Connections may be permanent or dynamic, the choice being made by the nature of the traffic.

    As an alternative to the manual approach, any BASICS, V25, V50plus or V150 unit may receive their configuration settings automatically from a V150 or a V200 hub unit using a mode known as Push Config. In this case, the hub unit contains all of the configurations for the clients in the network and pushes them out using a proprietary protocol at the start of the day.

    Each port generates clocks for its own use. Those ports need to be referenced to a common clock. Within your Vocality unit one or two clocks, known as GC1, and where available GC2, can be used to synchronize ports in each node. GC1 and GC2 allow two discrete and independent clock hierarchies to be used.

    The unit is often used in combination with satellite modems to provide telecommunications links between remote sites. This example describes the use of the V200 with a Paradise Datacom P300 modem that is fitted with the standard P1440 interface in RS422 mode, thereby allowing the use of the standard RS422/RS449 cable...

    5.20 Configuring broadcast services Vocality units can be used in point-to-multipoint networks, where a number of remotes may wish to receive the same data. In the example below, the hub unit is connected to a number of four wire voice feeds and each remote has chosen to listen to a selection from these.
