    1.3.1 Network Security Your KBU 64 contains an integral security facility, designed to protect it from being accessed by unauthorised users via the ISDN. If the security option is enabled (ANSWER is set to CLID), the answering KBU 64 will only accept a call originating from an ISDN number matching one of those stored on its file of telephone numbers.

    Hardware Configuration 2.1 Introduction The majority of KBU 64 configuration options are software controlled, and settings can easily be altered after the unit is installed in the system. However the physical interface characteristics of the USER and LINK ports (correct definition is crucial to the operation of your Kilostream backup unit) are defined using hardware links which are not accessible without removing the outer casing of the unit.

    . X21 and X21bis include V11, V35 and V24 as electrical interface options. Your KBU 64 has been designed to enable compatibility with any of these electrical variants, through the same 15-pin D-type connector. The option required is controlled by plug-in links on the main circuit board of the unit.

    Calls can be made to any telephone number on the ISDN, meaning data can be routed to any remote KBU 64 within the network. The intended ISDN automatic backup path could be called up and checked, leaving data to pass over the Kilostream link.

    6.3 Manually Dialling a Remote KBU 64 The DIAL command can be used to initiate a call over the ISDN to any remote KBU 64. The command is functionally the same as the BACKUP command, except that the KBU 64 will not automatically connect the USER port to the ISDN line (unless CONNECT is set to AUTO).

  • Page 99: Answering An Incoming Isdn Call

    NOTE: If the remote KBU 64 that you are calling has ANSWER set to CLID, it will reject your call, unless your telephone number is one of those held in the remote KBU’s CLID directory. Alternatively, a telephone number held within a specified STORE directory location can be used as the number to dial.

    User Manual 1. TALKWIRE must be set to ON at both ends of the required link. 2. Your KBU 64 is a dual channel device, serving two separate Kilostream links, each with an ISDN backup channel. Talkwire can operate over the ISDN or the Kilostream link, but can not use the same path being used to transmit user data.

  • Page 106: Using Talkwire During A Backup

    7.8 Using Talkwire During a Backup When the KBU 64 initiates a backup call, Talkwire can be set to ON or OFF, although it would normally be set to ON. When backup is initiated and Talkwire is set to OFF, the originating KBU 64 calls the remote KBU 64 over the ISDN line.
  • Page 107 Note: If the unit does not detect Talkwire due to poor data transfer, the switch-over will be controlled by the settings for CONNECT, at each KBU With CONNECT set to AUTO, the remote KBU 64 will wait for the user defined time-out to expire and then initiate the switch. With CONNECT set to MAN, the ISDN call will be released, without switching the user to the ISDN.
