  • Page 30: Nbx System Database

    The default dial plan for the SuperStack 3 NBX system is a 4-digit plan; for the NBX 100, it is a 3-digit plan. Changes that you make to any system settings, including changes made by importing a modified dial plan configuration file, are reflected in the database.
  • Page 31: Pretranslation

    When you import a dial plan, some parameters of the system change immediately. Others change only when you reboot the NBX system. 3Com recommends that you reboot the NBX system each time that you change the dial plan. Rebooting the system disrupts service to the telephones. Plan to reboot at a time that does not inconvenience telephone users.

    2: D HAPTER You can route incoming calls to the Auto Attendant port, and you can instruct the Auto Attendant to route these calls to any internal or external number. CAUTION: If you configure the Auto Attendant so that it can access any external number, you risk the possibility of toll fraud.
  • Page 33: Off-Site Notification

    Dial Plan Concepts and Overview The NBX system applies any Class of Service restrictions that are associated with the user's telephone to determine whether to make a call. The system also uses any pretranslator that a device uses and performs any required digit manipulation operations before it actually transmits the digits on the Analog Line Card or Digital Line Card port.

  • Page 37 Dial Plan Tables would collect all 4 digits of the extension. If the caller dials fewer than the Min number of digits, the system times out in 20 seconds. Example: If Digits = 2, Min = 4, and Max = 4, the system knows that if the first digit is 2, it must collect no less than 4 and no more than 4 digits before making the call routing decision.

    PPENDIX ONNE TIONS Overview of ConneXtions is a 3Com software product that allows you to use an ConneXtions appropriately configured Windows system as an H.323 gateway for use with NBX systems. H.323 gateways implement an ITU standard that allows telephone-like call connections to occur through an IP network.

    the H.323 protocol presents special problems for firewalls because it requires additional processing. To minimize packet delay through a firewall, verify that the firewall is configured to give H.323 packets a high processing priority. During installation, you can select a range of TCP or UDP ports to use with H.323 connections to provide more flexibility when using firewalls.

  • Page 403: Quality Of Service

    Connection Considerations Because so many devices share the same physical media on the Internet and on the local network, there is always the possibility of incomplete or degraded connections that arise from network congestion, device configuration, or addressing problems. Bridges, switches, routers, and firewalls can help to manage network congestion, conversions, and security.
  • Page 404 D: C H.323 G PPENDIX ONNE TIONS ATEWAY Bandwidth Bandwidth is the capacity to carry information. By using H.323, the same bandwidth that supports one uncompressed G.711 voice connection can, instead, support several compressed G.723 conversations with little noticeable difference in quality. Networks differ in the age of their equipment and in the quality of their service.

  • Page 421: Speed Dials

    Extension Lists You can configure H.323 ports for single-digit access (usually 8) instead of a specific 3-digit line extension. The single-digit access allows the NBX system to select an available line port when you place an external call. Internet IP line ports and CO (central office) line ports must never be assigned to the same extension list because they use very different dial plans.
