144 CHAPTER 5: ANALOG DEVICES ■ To transfer a call from an analog telephone, you must depress the hook switch briefly to obtain dial tone, and then dial the extension to which you want to transfer the call and hang up. ■ By using feature codes, you can create conference calls and forward calls using your analog telephone. See the NBX Feature Codes Guide in the NBX NetSet utility. ■ Configuring an analog port for fax operation optimizes the performance for inbound and outbound faxes but compromises audio quality. If you make a voice call using the analog device (for example, if you use the telephone portion of the fax machine), the quality of the audio may be affected. If you make a VTL call using the analog device, the audio may be unusable. Adding an Analog Terminal Card To add an optional Analog Terminal Card to the NBX system: 1 Log in to the NBX NetSet utility using the administrator username and password. 2 Click System-wide Settings > Auto Discovery. 3 Enable the Auto Discover Other Devices check box. 4 Click Apply. Inserting an Analog Terminal Card When you insert the ATC into the chassis, you may leave the system powered up. The Auto Discover process begins as soon as the system senses the new card. Functionally, ATCs 3C10114 and 3C10114C are identical. However, 3C10114C uses some different internal components so that 3C10114C requires NBX software release R4.1 or higher. To insert the analog terminal adapter card: 1 Find the MAC address of the ATC on the label on the card. 2 Record the MAC address for the configuration process. 3 Select a slot for the card in the chassis and use a Phillips screwdriver to remove the blank faceplate from the slot.
