The description will focus on the configuration of connections, i.e. software settings.

  • Page 42: Technical Basics

    The 2-Mbit interfaces of your device Let's have a brief look at the 2-Mbit interfaces of your device and the technology behind them. Depending on the model, your ELSA LANCOM Business 6000 features up to three 2-Mbit interfaces: ELSA LANCOM Business 6001 one X.21 interface...

  • Page 43: G.703 - Simple Basis For 2-Mbit Connections

    At the time that the standard was established, 64 kbps were needed for clean voice communications. As the timeslots are the smallest independent units for an individual connection, they were fixed at a bandwidth of 64 kbps. ELSA LANCOM Business 6000...
  • Page 44 In G.704, timeslots can be optionally coupled for greater bandwidth. The coupling is set in the terminal devices. The coupled timeslots result in connection channels with the appropriate bandwidth. These connection channels can also be used for fixed connections to a variety of remote stations.

  • Page 45: Which Method For Your Purpose

    Connection via 2-Mbit interface The devices of the ELSA LANCOM Business 6000 series are designed for the operation of a single connection channel only and do not support the free assignment of timeslots to connection channels. G.704 only passes these timeslot blocks for the transmission of user data on to higher-level protocols.

  • Page 47: Setting Up The Basic Protocols

    Setting up the basic protocols As complex as the world of 2-Mbit standards may be, the configuration of your ELSA LANCOM Business is still a simple matter. To set up Internet access or interconnect two networks using a 2-Mbit connection, launch the appropriate wizard using LANconfig or WEBconfig.
  • Page 48 G.703/G.704 These settings are virtually ideal for establishing connections between two ELSA routers.

Only two of the three 2-Mbit interfaces of the ELSA LANCOM Business 6021 (one X.21 and two G.703 interfaces) can be used simultaneously. You thus have the choice of using the two G.703 interfaces in parallel, or using a G.703...

Setting up filters under ELSA WEBconfig or Telnet The configuration under WEBconfig or Telnet is somewhat more difficult than under LANconfig. Here the filter functions are set in the filter list which is based on the entries of two other tables.
  • Page 60 Host names can only be used if the ELSA LANCOM Business can resolve the names in IP addresses. To do this the ELSA LANCOM Business must have learnt the names via DHCP or NetBIOS, or the assignment must be entered statically in the DNS or IP routing table.

    In the simplest case, all that is required is to connect the new device to a network without other DHCP servers and switch it on. The DHCP server then interacts with ELSA LANconfig using a wizard and handles all of the address assignments in the local network itself.

  • Page 63: How Are The Addresses Assigned

    It then uses the IP address '10.0.0.254' for itself and the address pool '10.x.x.x' for the assignment of IP addresses in the network. In this state, the DHCP server ELSA LANCOM Business 6000...
  • Page 64 If no server is specified in the relevant fields, the router passes its own IP address as a DNS address. This address is determined as described under 'IP address assignment'.

  • Page 131: Callback Functions

    For example: Internet access If Internet access for a local network is realized via the ELSA LANCOM Business, the assignment of IP addresses can occur in a reverse manner. Configurations are possible in which the ELSA LANCOM Business does not have a valid IP address in the Internet and is assigned one by the Internet provider for the duration of the connection.
  • Page 132 When the remote station is found in the numerical list, a quick callback is carried out, i.e., the ELSA LANCOM Business sends a special signal to the remote station and calls back immediately when the channel is clear again. After approx. 2 seconds, the connection is established.
  • Page 133 The called party allows the caller to indicate the callback number. The party called knows the callback numbers and only calls these back. Via CBCP, it is possible to establish connection to ELSA LANCOM Business from a PC with Windows operating system and also to be called back by this PC.

The same applies to all options: ELSA LANCOM Business drops the connection after authenticating the remote station and then calls back the station three seconds later.
