4 ANALOG LINES This chapter tells you how to install and how to verify the successful installation of optional Analog Line Cards and to configure analog ports. The NBX system treats a line card port as an extension and assigns a unique extension number to each port. You use the Auto Discover feature to detect analog line ports, and you define the starting address used by the Auto Discover process in the system dial plan. For a 4-digit dial plan, the starting address is 7250. For a 3-digit dial plan, the default starting address is 750. The Auto Discover process assigns the first unassigned number to the first analog line port. Before you install any Analog Line Cards, you may want to configure the Outdialing Prefixes. For information on this topic, see "Outdialing Prefix Settings" in Chapter 2 of the Administrator's Guide or the Help for Dial Plan > Configure > Set Outdial Prefixes. Auto Discover Analog Line Cards To Auto Discover analog line ports: 1 Log in to the NBX NetSet utility using the administrator username and password. 2 Click System-wide Settings > Auto Discovery. 3 Clear all check boxes associated with Auto Discover. 4 Enable Auto Discover Other Devices. 5 Click Apply.
