  • Page 10: Chapter 1: Quick Start

    ISDN Line Simulator User’s Manual CHAPTER 1: QUICK START The ILS-2000 Line Simulator is easier to operate than most communications devices designed for ISDN-BRI applications. It functions in the background, providing two lines of end-to-end ISDN-BRI service. Because the Simulator was designed primarily for people who demonstrate, functionally test, or configure ISDN-BRI devices, you do not need to understand ISDN protocols or read the entire User’s Manual to use it.
  • Page 11 Step 8 Step 9 NOTE: The instructions may specify that your communications device requires power from a secondary source, such as a wall adapter. It may not be necessary to connect a power source when using the Simulator. See Specifications for more details. Step 10 Determine which ISDN-BRI interface is compatible with your IMPORTANT: Either or both Simulator ports may be used during simulation, but only one interface (S/T or U) may be selected at each...

  • Page 13: Ils-2000 Operation

    IMPORTANT: Some devices let you change the ISDN protocol to support the type of ISDN switch the telephone company has installed. If you change your device’s protocol, you must change the Simulator’s Switch Type configuration to match. If you change any one device’s ISDN protocol, then all devices connected to the Simulator must be configured for that protocol.
  • Page 14: What To Read Next

    ISDN Line Simulator User’s Manual devices, particularly those that support video conferencing or LAN adaptation, need both B Channels for a single call. If your communications device requests any of these services, the Simulator provides the necessary processing and resources. A special case, which uses the D Channel and X.25 packet data transmission is also supported and may occur while both B Channels are connected.
  • Page 15: Chapter 2: Isdn-Bri

    CHAPTER 2: ISDN-BRI Technology Overview The Integrated Services Digital Network - Basic Rate Interface (ISDN-BRI) is a technology that gives individuals affordable access to the world’s largest digital network using the copper wire currently entering their home or office. With ISDN-BRI, users may connect almost any form of personal communications device to a single phone line and establish multiple, simultaneous voice and data connections at speeds up to 128 thousand bits per second.
  • Page 16: Network Termination-1 (Nt-1)

    ISDN Line Simulator User’s Manual Network Termination-1 (NT-1) The U Interface terminates at a device called a Network Termination-1, or NT-1. This device converts the U Interface to an S/T Interface. It also permits loop back and testing by the telephone company and a means of routing local power to devices previously designed to receive power from the line, such as a telephone.
  • Page 17: Tei Assignment

    SAPI 63 addresses the Signaling Access Controller (SAC), which negotiates and assigns the second packet address number, called a Terminal Endpoint Identifier or TEI. The TEI is a unique number for each Terminating Equipment on a particular line. For example, if a packet addressed to SAPI 0 and TEI 3 is sent to four ISDN devices connected to a single line, only the Call Control function (SAPI 0) of the device assigned TEI 3 will acknowledge and process the packet.

The European Economic Community, (ECC) is currently consolidating various national versions to comply with the European Telecommunications Standards Institute (ETSI) protocol.
  • Page 19: Chapter 3: Provisioning And Operation

    CHAPTER 3: PROVISIONING AND OPERATION The instructions for many ISDN-BRI communications devices may specify Provisioning required of the telephone company. Provisioning is a means of configuring the ISDN switch so it knows what kind and how many calls communications devices can support, up to the limits imposed by ISDN-BRI technology.

    ISDN Line Simulator User’s Manual installation, a message may appear saying that a certain file could not be installed because it is already installed and in use. Continue with the installation until complete. A Program Window will be created that is labeled ILS Configuration and includes an icon labeled ILS Configuration.
  • Page 21: General Operation

    General Operation Provisioning of features using the ILS-2000 configuration software allow the user to select from several stored configurations, as well as allow the user to store other configurations as needed. If a stored configuration is selected, and any feature is changed, the Configuration Name changes to (Untitled). If you attempt to exit the program without saving the configuration, you will be prompted to do so.
  • Page 22: D Channel X.25

    ISDN Line Simulator User’s Manual Important: When the Simulator configuration is changed, always reinitialize any connected devices. All devices must be compatible with the selected switch protocol. D Channel X.25 Packet Handling Function (PHF) ISDN-BRI permits the use of the 16Kbs D Channel, usually reserved for ISDN signaling, to exchange X.25 LAP-B user data with a host system.
  • Page 23: B Channel Provisioning

    STEP 3 STEP 4 STEP 5 NOTE: Some terminals require that you send an X.25 RESET command manually before the terminal will establish a PVC connection. B Channel Provisioning Some ISDN-BRI communications devices, usually LAN gateways and other Terminal Adapters, do not use ISDN Call Control to establish calls or allocate B Channels.
  • Page 24: Caller Id

    ISDN Line Simulator User’s Manual To change the Phantom Power setting, follow these steps: STEP 1 STEP 2 STEP 3 STEP 4 STEP 5 Caller ID This service, also referred to as Automatic Number Identification (ANI) or Calling Line Identification (CLID), allows Terminating Equipment with display support or call screening features to identify the calling party before accepting the call.

    ISDN Line Simulator User’s Manual Information Element unique to that terminal. The EKTS terminal stores the TEI in its non-volatile memory. All subsequent SETUP messages sent to that line may then address all, some, or only one device using the TEI. If the communications device does not store a TEI, then the Simulator’s EKTS setting should be disabled.
  • Page 27: Key Hold

    Some devices permit programming of the Directory Number(s) into the terminal and associate one or more Call Appearances to manage each DN. The terminal indicates incoming calls using the received Called Party Number Information Element and lighting the first unused (idle) Call Appearance assigned to that DN.
