222CHAPTER 3: DEVICE CONFIGURATION Connecting and Managing Analog DevicesA 4-Port Analog Terminal Card or a Single-Port Analog Terminal Adapter (ATA) allows ordinary analog (2500-series compliant) telephones, including cordless telephones and Group-3 facsimile devices, to operate with NBX systems. Certain limitations apply because of the differences between an analog device and the custom NBX Telephone: ■A user dials 500, then ** on a telephone connected to an ATA to gain access to voice mail. ■A telephone can make or answer only one call. The second incoming call goes to voice mail. ■ATC ports and ATAs support call transfer. This section discusses these topics: ■Adding a 4-Port Analog Terminal Card ■Adding a Single-Port Analog Terminal Adapter (ATA) ■Modifying an Analog Terminal Port ■Removing an Analog Terminal Adapter ■Viewing The Status of an Analog Terminal Adapter Adding a 4-Port Analog Terminal CardTo add a 4-Port Analog Terminal Card to the NBX system using Auto Discovery: 1In the NBX NetSet - Main Menu window, click System Configuration. The System Configuration dialog box (Figure 70 ) appears. 2Click System-wide. The System Settings dialog box (Figure 71 ) appears. 3Click the Auto Discover Telephones check box to select it. 4Click OK. 5Insert the 4-Port Analog Terminal Card into the chassis. 6Wait 1 minute for the system to discover the card. 7In the NBX NetSet - Main Menu window, click Device Configuration. 8In the Device Configuration dialog box, click the ATA tab. (See Figure 76 .) 9The four ports of the 4-Port Analog Terminal Card appear in the list of ATAs, along with the ports of any previously discovered 4-Port Analog Terminal Cards, and any previously discovered Single-Port Analog Terminal Adapters (ATAs).

Connecting and Managing Analog Devices223 Extension Assignments (3C10117 ATC) Each of the four ports on a 3C10117 Analog Terminal Adapter Card has a MAC address. The first port has the same MAC address as the card, and the remaining three ports have sequential MAC addresses incremented by one hexadecimal digit. See Table 36 : The extensions assigned to these ports by the NBX system may not be in order. For example, if the NBX system assigns extensions 7258, 7259, 7260, and 7261 to the ATC ports, it might assign 7258 to port 3. To determine which extension is associated with a given port, you must access the ATA tab in the NBX NetSet utility and examine the list of ATAs and ATC ports. For example, to determine the extension assigned to the third port, look for the ATC port with a MAC address that is two hexadecimal digits higher than the MAC address of the board. The extension of the port is in the first column (Ext.). After you have added the Analog Terminal Card, you can configure the parameters for each of the four ports. See “Modifying an Analog Terminal Port” later in this chapter. Extension Assignments (3C10117C ATC) On a 3C10117C Analog Terminal Card, there is only one MAC address. Each of the four ports is assigned a unique virtual device number (1 through 4) so that the NBX software can address each port separately. When you select the ATA tab, and view the information, the port number appears after the MAC address, enclosed within square brackets. See Table 37 .

224CHAPTER 3: DEVICE CONFIGURATION The extensions that are assigned to these ports by the NBX system may not be in order. For example, if the NBX system assigns extensions 7258, 7259, 7260, and 7261 to the ATC ports, it might assign 7258 to port 3. To determine the extension assigned to any port on a 3C10117C ATC: 1Click the ATA tab. 2Look for the combination of MAC address and port number that you want. The extension associated with the port is in the first column (Ext.). After you have added the Analog Terminal Card, you can configure the parameters for each of the four ports. See “Modifying an Analog Terminal Port” later in this chapter. Adding a Single-Port Analog Terminal Adapter (ATA)To add a Single-Port Analog Terminal Adapter (ATA) to the NBX system: 1In the NBX NetSet - Main Menu window, click Device Configuration. The Device Configuration dialog box appears (Figure 49 ). 2Click the ATA tab. The ATA dialog box appears (Figure 76 ).
