  • Page 8: Introducing The V100

    The 1U chassis is the most compact format for mobile comms and its rugged and reliable design makes the V100 ideal for military or commercial deployment in remote areas. By linking many chassis together, a sophisticated hub site can be commissioned which exploits the versatile routing and bandwidth agility of the product.
  • Page 9 A V100 network may be managed from the dedicated supervisor port of any chassis in the network. The user logs on to the required unit and configures the network from the most convenient management port...

  • Page 10: Capabilities

    1.2.3 Data The V100 chassis has two dedicated data ports in the chassis and further ports are available by adding 4-channel option cards, to yield a maximum of ten channels per chassis. Any port may be synchronous or asynchronous, at speeds up to 2Mbps and may be used as an aggregate or a tributary.

  • Page 11: Isdn Bri Extender

    The V100 system is designed to operate on asymmetric links through its versatile clocking architecture. It is therefore not only possible to select different coder/decoder types but to operate in simplex mode if required.

  • Page 12: Tdm Link Card

    UDP relay function enhances this by allowing communication between a remote client and a server on the home network. Users can now plug their laptop into the remote V100 and log in to their home network, surf the internet and pick up E-mail.

  • Page 13: Call Routing

    In order to assign the most efficient route for packets to reach the destination, hubs require knowledge of the available aggregate routes to adjacent nodes in the network, together with the current bandwidth loading on each trunk port. A Routing page tells the V100 which aggregate to use to reach the destination port.

  • Page 14: Control And Monitoring

    The versatility of the system is maintained using upgradeable software running on a selection of option cards, which may be deployed in any V100 network. In order to maintain and support equipment in the field and also to provide upgrades and feature enhancements, all system software is held in field- programmable FLASH memory.

  • Page 15: Topologies

    1.3.1 Star Networks The ability to configure multiple aggregate ports allows Star network topologies to be built with the V100, ranging from simple point-to-point systems at one extreme to a cluster with up to 10 remotes per chassis at the other. Connections may be permanent or dynamic, the choice being made by the nature of the traffic.

  • Page 16: Mesh Networks

    1.3.2 Mesh Networks The expansion capabilities of the V100 make it an ideal foundation for a full-mesh network. Since any data port may be used as an aggregate link, complex networks may be designed which exploit the versatility of the system. Point-to-point connections for data channels, ISDN basic rate extension or MPEG audio broadcast happily co-exist alongside dynamic voice traffic or asynchronous data links.

  • Page 17: Broadcast Networks

    1.3.3 Broadcast Networks The V100 may be used in broadcast applications, where many remote units may wish to select a receive channel from a large outbound carrier. Often there is also a requirement for a return carrier from each site, which can be transmitted back to the hub. The flexibility of the unit is such that this kind of network topology can be used with all of the voice, data and IP facilities to provide a large network of users with fully integrated comms services.

  • Page 37: Configuring V100

    The Node ID The most important item in the V100 configuration is the Node ID. This is a unique number between 0 and 239 which specifies each chassis in the network and it must be programmed into the unit before anything else.
  • Page 38 C O N F I G U R I N G V 1 0 0 Throughout the configuration of the V100, references are made to slot locations and port numbers in the network. By convention, the syntax used is “NODE:SLOT:CHANNEL”, where NODE is the Node ID, SLOT is a number which means the chassis (0), Option slot 1 (1), or Option Slot 2 (2) and CHANNEL is a number which means the particular channel number within that slot.

  • Page 39: Using The Supervisor

    3.3.1 User Interface The V100 provides either a formatted menu control structure for interactive user control, or a simple Teletype mode for interface to a network management system. The use of the formatted supervisor is described here; the Teletype mode is described in a separate manual supplement.

Such systems in the V100 network could take the form of a unit connected via the HSC or an intermediate node, where the carrier status of the overall link is unknown. In such a case the call is placed by the local PBX, which sees the local port is free and raises the M-lead.

    E X A M P L E S Use with Inmarsat M4 Terminals The V100 multiplexer is often used in combination with Inmarsat M4 terminals, using the integral ISDN2 adaptor (Part number VI68711) to interface directly with the terminal. In the example below, the V100 units are equipped with 4 voice channels and the standard 2 data ports.

The clocking menu at each end should be configured as follows: V100 Versatile Multiplexer Technical Manual Version 2.2 Page 198 of 231...
  • Page 199 In order for the system to use the ISDN adaptor as its aggregate, the implicit routing is not sufficient, since the unit cannot communicate with any other nodes without any permanent aggregates set. It is therefore necessary to set the ROUTING pages as follows:. V100 Versatile Multiplexer Technical Manual Version 2.2 Page 199 of 231...
  • Page 200 Node1. The V100 data channels should now be configured. In this example, the ISDN service is used as the sole aggregate and so ports 0:1 and 0:2 should be configured as Tributaries and left unmapped. If they are permanently mapped, they will cause the ISDN service to be dialled.
  • Page 201 UNIT0. Once a suitable signal is acquired on the Inmarsat terminal and the V100 equipment is configured, the ISDN port should be connected to the RJ45 port of the V100 ISDN terminal adaptor using a straight 8-way CAT5 cable.

    Chapter 7 Appendix B: Port Numbering The V100 uses a node:slot:channel port name representation. These port names appear in the user interface (often just as slot:channel when dealing with local ports). Some port numbers are obvious - 1:1 when a voice card is in slot 1, is voice port 1 on that voice card – others are less obvious and are based on internal virtual representations.
