Host NameAn IP setting for the NBX system.
A Host name functions only if you add the name to the name 
resolution system. If you do not do this, then you must enter 
the IP address in the browser when you want to access the 
NBX NetSet utility.
SMTP Domain 
NameThe name of your SMTP domain.
Required for Off-Site Notification by e-mail.
IP AddressThe IP address of the NBX system.
Default GatewayThe IP address of the destination host for any IP packet not 
addressed to a host on the local subnetwork.
Subnet MaskAn IP setting that identifies the network and host portions of 
an IP address on the network.
Primary DNSThe IP address of the primary DNS server. You must specify at 
least a primary address to use e-mail Off-Site Notification.
Secondary DNSThe IP address of the secondary DNS server. If you specify two 
DNS IP addresses, they must be the primary and secondary 
addresses.
Tertiary DNSThe IP address of the tertiary DNS server.
Network ProtocolThe transport mechanism for voice packets.
Ethernet only: All communications are at the Ethernet frame 
layer.
Standard IP: IP communications are used for traffic between 
NBX system addresses.
NOTE: Every device needs an IP address.
IP communications are optional features of the NBX system 
and require separate licensing. 
IP On-the-Fly: An implementation of IP communications in 
which Layer 2 (Ethernet) devices are temporarily assigned a 
Layer 3 (IP) address only when they need to communicate with 
a Layer 3 device on a different subnetwork. The IP address is 
assigned from an address pool defined by the NBX system 
administrator. After the Layer 2 device returns to the idle state 
the IP address is returned to the pool of available addresses for 
future use.
If you have the appropriate license and select IP On-the-Fly in 
the Network Protocol list, you must return to the Current 
System Settings window, select IP Addresses and add the 
IP addresses associated with IP-on-the-Fly. There may be 
unpredictable results in other system functions if you have 
Network Protocol set to IP-on-the-Fly but do not have any 
IP telephones or addresses.

Handsfree on 
Transfer(Affects NBX Business Telephones only) This setting governs 
the way an NBX Business Telephone responds to a transferred 
call when a user enables the HANDS FREE button on the 
telephone or uses the HANDS FREE feature code (100).
Transferred calls include:
■Internal calls from other NBX users, both direct and 
transferred
■External calls transferred via an automated attendant
NOTE: Calls that directly arrive at the NBX Business Telephone 
via an analog telephone line or Digital Line Card channel ring 
on the telephone in the normal way. To answer the call, the 
user must either pick up the handset or press the Speaker 
button. 
Handsfree on Transfer Enabled
When the HANDS FREE button on an NBX Business Telephone 
is activated and the Handsfree on Transfer function is enabled 
on the NBX system, a call that is transferred to the telephone 
causes the telephone to issue a two-second hands-free 
warning tone.
The telephone user does not need to take any action to 
answer the call because, immediately after the warning tone, 
the call is connected using the speaker phone.
Handsfree on Transfer Disabled
When the HANDS FREE button on an NBX Business Telephone 
is activated but the Handsfree on Transfer function is disabled 
on the NBX system, a call that is transferred to the telephone 
ring in the normal manner, whether or not the HANDS FREE 
button is activated.
Internal calls cause the telephone to issue a two-second 
hands-free warning tone. The user does not need to take any 
action to answer the internal call because, immediately after 
the warning tone, the system connects the call using the 
speaker phone.
If an external call is blind transferred manually to the NBX 
Business Telephone, the call rings on the telephone in the 
normal manner and the HANDS FREE button is ignored.
Virtual LAN 
EnabledAdds a Priority 6 Virtual LAN identifier to each Ethernet frame. 
Virtual LAN IDIf the VLAN Enabled box is checked, you must add the Virtual 
LAN identifier in this field.

system VLAN tags outgoing voice and control packets 
intended for devices on the VLAN you specified in the Virtual 
LAN ID text box.
System-wide CLIRSuppresses the transmission of caller ID for outgoing calls.
 Music On Hold Enables Ethernet multicasts for Music On Hold (MOH). MOH is 
automatically enabled if Music on Transfer is enabled.
MOH Audio should be enabled only if you have a MOH device 
connected to the system. 
Music on TransferEnables MOH audio for Call Transfer; requires MOH to be 
installed and enabled. Music on Transfer is automatically 
disabled if MOH is disabled.
One Button 
TransferEnables system users to transfer a call by pressing the Transfer 
button only once. If this box is not checked, call transfers 
require users to press the Transfer button once to start the call 
transfer and another time to complete the transfer of the call.
NBX MessagingAllows you to enable or disable NBX Messaging after you 
install a third-party messaging license. By default, this 
checkbox is selected but not accessible until you install a 
third-party messaging license. If you disable NBX Messaging by 
clearing this checkbox, all NBX Messaging icons and headings 
become inactive throughout the NBX NetSet utility.

Advanced Regional Settings
The NBX system also allows you to choose different regional settings for 
the system voice prompts, the technical tones and cadences, and the 
online user (not administrator) documentation. For example, you may 
require local tones and cadences but may want the documentation to be 
in English and the voice prompts in Australian English.
You can select separate regional settings for:
■Voice prompts — The Auto Attendant voice prompts.
■Documentation — The NBX Telephone Guide, the User Help, and the 
quick reference cards.
■Tones and Cadences — The tones and the patterns of rings (cadence) 
versus silence. Tones and cadences vary from country to country. 
Examples:
■United States ringing cadence (pattern) is 2 seconds of ring 
followed by 4 seconds of silence.
■United Kingdom ringing cadence is 2 rings within approximately 2 
seconds followed by 2 seconds of silence.
■United States busy tone is 0.75 seconds of tone followed by 0.75 
seconds of silence.
To enable different regional settings, select System Configuration > 
System Settings > Regional Settings > Advanced. See the Help for 
procedures on selecting multiple regional settings.
Date and TimeIf necessary, you can set the NBX system date and time. It is important 
that the date and time are accurate because the system date and time:
■Appear on an idle NBX telephone display
■Affect business hours behavior
■Affect time-dependent prompts in the Auto Attendant
■Affect the time and date stamp on voicemail
To select the system date and time, select System Configuration > System 
Settings > Date and Time. See the Help for the procedure on setting the 
system date and time. 
						

							336CHAPTER 5: SYSTEM CONFIGURATION
TimersSystem timers enable you to set time-out periods for the NBX system 
features that are described in Table 52
. To set timers, select System 
Configuration > System Settings > Timers. See the Help for the procedure 
on setting timers.
Ringing PatternsYou can set system-wide ringing patterns to distinguish between internal 
and external calls. You can choose one, two, or three rings to distinguish 
between internal and external calls. 
Do not confuse ringing patterns with ringer tones, which NBX system 
users can set for their telephones using the NBX NetSet utility. For 
information on setting a user’s ringing tones, see the NBX Telephone 
Guide or the User Help.
To set ringing patterns, select System Configuration > System Settings > 
Ringing Patterns. See the Help for instructions.
Table 52   System Timers Fields
FieldPurpose
Forward Voice Mail On 
TimeoutWhen a telephone’s FWD VMAIL button is enabled, this 
field specifies the duration of ringing before a call is 
forwarded to voice mail.
If you set this time to under 6 seconds, caller 
ID information is not captured in voicemail.
Forward Voice Mail Off 
TimeoutWhen a telephone’s FWD VMAIL button is disabled, this 
field specifies the duration of ringing before a call is 
forwarded to voice mail.
Line Port Hold TimeoutFor a call originating on an outside line (Analog Line Card 
port), the length of time that the call remains on hold 
before it rings at the extension that placed the call on hold.
Call Park TimeoutThe length of time that a call can be parked before it rings 
at the extension that parked the call.
Conference TimeoutThe length of time before a conference attempt is 
abandoned. Applies to a blind conference only. The 
timeout takes effect under these conditions:
■Two people, A and B, are involved in a call and one of 
them attempts to blind conference another person, C.
■C does not answer and C’s voice mail does not pick up 
the call.
After the Conference Timeout period, the system stops 
ringing C’s telephone, stops attempting to conference 
with C, and reverts to the call between A and B.
Transfer TimeoutThe length of time that a transferred call attempts the 
transfer before it rings back to the caller’s extension. 
						

							System Settings337
Multicast AddressesThe NBX system uses IP multicast addressing to distribute information for 
these system features:
■Mapped line appearances
■Music on hold
■Internal page
■External page
■Conference calls
These features are available on Layer 2 and Layer 3 IP devices. The 
IP implementation uses Internet Group Management Protocol (IGMP) 
to transmit and distribute the necessary data and audio. 
If you configure your NBX system to use IP On-the-Fly or Standard IP and 
your switches use IGMP Snooping, you must have an IGMP Host on the 
network. Typically, an IGMP Host is an IP Multicast Router or a switch that 
has IGMP Query capability.
The NBX system IGMP is an implementation of administratively scoped 
IP multicast that uses three scopes of administration:
■Local scope — Limited by local routers with IP addresses 239.255.0.0 
through 239.255.0.16
■Organizational local scope — Limited by boundary routers with 
IP addresses 239.192.0.0 through 239.192.0.14
■Global scope — IP addresses 224.2.0.0 through 224.2.127.253
IGMP may not be available in all systems or network topologies. All of the 
routers between the various components must support IGMP and the 
necessary router protocols to establish a path for the IP multicast packets.
Each event that occurs in an IGMP setup, such as taking a telephone off 
the hook, causes a packet of 200 Kb to 300 Kb to be sent. 
The default settings for the IP multicast addresses should work in most 
network environments. Certain addresses are reserved. 
The MAC address and the IP address displayed on any one line of the 
Multicast Address List window are not related. 
						

							338CHAPTER 5: SYSTEM CONFIGURATION
There are two methods for selecting multicast addresses: 
■Change IP — Lets you select a starting address for all entries. 
Changing IP multicast addresses is a quick way to change the range of 
NBX system multicast addresses, to avoid conflicts with other 
equipment on your network.
■Change bins — Lets you change a single entry by selecting from a list 
of available bins. Changing IP bins is useful for changing a single 
address that may conflict with another system device. Consult your 
network administrator to determine which address is in conflict and 
the new address to choose.
To change multicast addresses, select System Configuration > System 
Settings > Multicast Addresses. See the Help for instructions.
IP AddressesThis window allows you to add or delete a range of IP On-the-Fly 
addresses. Select System Configuration > System Settings > IP Addresses 
to perform these functions. See the Help for the procedure on adding or 
deleting IP addresses.
The IP Addresses button appears only if you have IP On-the-Fly enabled in 
System Configuration > System Settings > System-wide.
Maintenance AlertsIf you have a SuperStack 3 NBX system with disk mirroring or dual power 
supplies and with NBX Messaging enabled, you can:
■Configure maintenance alert voice mail messages so that they appear 
to come from one NBX system user.
■Designate up to 15 NBX system users to receive maintenance alerts. 
Alert messages are defined by the NBX system. The content depends on 
the cause of the alert.
When a user receives a maintenance alert message, the source of the 
message depends on whether you have configured an NBX system user 
as the author of maintenance alert messages. See Table 53
 for details.
Table 53   Source of Maintenance Alert Messages
Message TypeAuthor ConfiguredNo Author Configured
Local Voice Mail 
MessageThe configured system user is 
announced as the sender of the 
message.An outside caller is announced as the sender of the 
message. 
						

							Speed Dials339
See the Help for the procedures on setting the maintenance alert author 
and specifying users to receive maintenance alerts.
Speed DialsYou can create up to 100 System Speed Dial numbers. You can also 
create system speed dial and personal speed dial button definitions and 
assign them to groups. 
Any telephone in a group has access to the same button definitions. 
Users can create personal speed dial definitions for buttons that do not 
already have a button mapping. Users can also change definitions for any 
buttons mapped as personal speed dial buttons, even if those buttons are 
defined in the Group Button Mappings. 
System speed dial numbers are not subject to Class of Service (CoS) 
restrictions, so a speed dial number mapped to a number that is a toll call 
is available to users even if their CoS does not allow toll calls. Personal 
speed dial numbers are subject to CoS.
Do not confuse speed dial codes with extension numbers.
To set up system speed dials, select System Configuration > Speed Dials. 
See the Help for these speed dial procedures:
■Adding or modifying a system speed dial
■Removing a system speed dial
■Printing system speed dials

							340CHAPTER 5: SYSTEM CONFIGURATION
To enter business information, select System Configuration > Business 
Identity. See the Help for procedures to modify these types of 
information:
■Business information
■Business hours
■System mode
Business InformationYou can enter basic information about your business on this dialog box, 
including name, address, and telephone and Fax numbers.
Business HoursThe business hours dialog box allows you to define business hours for 
three separate times of day, or service, modes: Open, Lunch, and Other. 
Any time period that does not fall within these specified hours is 
considered Closed. Business hours are directly linked to time-of-day 
service modes and can affect other settings in the system, such as the 
Auto Attendant. 
You can manually specify that the system operate in a given mode, or set 
it to operate automatically. See “System Mode”
 later in this chapter.
If the system is left in an automatic state, it constantly compares the 
current time of day and day of week with the business hour tables. The 
system knows the current day of the week and proceeds across the tables 
in a sequential manner, looking for business hours that match the current 
time of day. The system examines the three tables sequentially: first the 
Other mode, then the Lunch mode, and then the Open mode. The 
system moves across the tables until it finds a match.It skips a blank table. 
System ModeYou can manually specify that the system operate in a given mode, or set 
it to operate automatically. If necessary, you can force the system into a 
specific Time of Day Service mode without having to reconfigure other 
system settings, such as Business Hours. 
If the system is left in an automatic state, it constantly compares the 
current time of day and day of week with the business hour tables. 
SecurityThe Security function enables you to set system passwords, including the 
administrator, Auto Attendant, and reporting passwords.
