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).

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
).

Modifying an Analog
Terminal PortYou can modify the configuration of an Analog Terminal Card port or a 
Single-Port ATA at any time.
To modify an analog device configuration:
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
). This dialog 
box shows all ports on 4-Port Analog Terminal Cards and all Single-Port 
Analog Terminal Adapters (ATAs).
3Select the analog device that you want to modify.
Return busy tone when 
device is in useReturns a busy tone to the caller if the telephone 
attached to this ATC port or ATA is in use.
NOTES:
■If you enable this check box and the user enables the 
Do Not Disturb feature on the analog telephone, 
callers hear a busy tone whether or not the telephone 
is in use.
■If you enable this check box and configure an Analog 
Line Card port such that the ATA is the auto 
extension, when an external call arrives on the Analog 
Line Card port and rings directly on the ATA, the 
caller hears Ring No Answer instead of a busy tone. 
This is the way that the NBX system works; it cannot 
seize the Analog Line Card port until the ringing 
telephone is answered.

Removing an Analog
Terminal AdapterYou can remove either a Single-Port Analog Terminal Adapter (ATA) or 
one of the ports on a 4-Port Analog Terminal Card from the system at any 
time. Any device connected to the ATA is also removed from the system.
To remove an Analog Terminal Adapter:
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
).
Use the MAC addresses to determine whether an item in the list is a 
Single-Port Analog Terminal Adapter (ATA) or one of the ports on a 4-Port 
Analog Terminal Card. Ports on a 3C10117 4-Port Analog Terminal Card 
have MAC addresses that differ by two hexadecimal digits. Ports on a 
3C10117C Analog Terminal Card all have the same MAC address and use 
a Virtual Device Number to identify each port. The port number appears 
after the MAC address, enclosed in square brackets. A Single-Port ATA 
has a unique MAC address with no port number.
3Select the Single-Port ATA or the port on a 4-Port Analog Terminal Card 
you want to remove.
4Click Remove. A dialog box prompts you to confirm the removal.
5Click Ye s. The system removes the item you selected.
Viewing The Status
of an Analog
Terminal AdapterYou can view the status of either a Single-Port Analog Terminal Adapter 
(ATA) or one of the ports on a 4-Port Analog Terminal Card at any time.
To view the status of an ATA or a port on a 4-Port Analog Terminal Card:
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
).
Use the MAC addresses to determine whether an item in the list is a 
Single-Port Analog Terminal Adapter (ATA) or one of the ports on a 4-Port 
Analog Terminal Card. Ports on a 3C10114 4-Port Analog Terminal Card 
have sequential MAC addresses. Ports on a 3C10114C 4-Port Analog 
Terminal Card all have the same MAC address followed by a Virtual 
Device Number (VDN), enclosed in square brackets. A single-port Analog 
Terminal Adapter has a unique MAC address with no port number.
3Select an ATA or port from the list.
4Click Status. The Device Status dialog box appears (Figure 79
).
