To set these passwords, select System Configuration > Security. See the 
Help for procedures on changing these types of passwords:
■Change Administrator Password — Resets the password for 
administrator access to the NBX NetSet utility.
After you change an administrator password, write it down and store 
it appropriately. There is no “back door” password to use if this 
password is lost. If you change the default 4-digit password to an 
8-digit (or longer) password, you cannot revert to a 4-digit password.
■Reset User Password — Resets the password to the user’s telephone 
extension. After resetting the password, instruct the user to change to 
a new password as soon as possible to ensure system security. 
■Auto Attendant Password — Prevents access to Auto Attendant 
settings and functions.
■System Backup Password — Enables automated backups from an 
external system. 
■Reporting Password — Used in conjunction with Call Detail Reports, 
an optional component of the NBX system. See “Call Reporting”
 in 
Chapter 8
 for more information.
■Virtual Tie Lines Password — Enables “hop off” from calls over 
virtual tie lines. See Chapter 2
 for more information on setting up 
VTLs.
TAPI SettingsYou must configure system-wide Telephony Application Programming 
Interface (TAPI) settings before users can download the NBX TAPI Service 
Provider (NBX TSP). You can set a maximum number of TAPI clients in the 
system. You can also require users to enter passwords for TAPI devices. 
Before configuring system-wide TAPI settings, install the appropriate TAPI 
software. After you have the software installed, select System 
Configuration > TAPI Settings to configure TAPI settings. See the System 
Configuration Help for procedures on configuring TAPI settings. See the 
Downloads Help for procedures on downloading NBX TSP software. 
Disk MirroringThe SuperStack 3 NBX Solution supports disk mirroring, using RAID1 
technology, to provide data security and throughput speed. 
						

							342CHAPTER 5: SYSTEM CONFIGURATION
When the mirror disk is fully partnered with the master system disk, all 
data that is written to the master disk is also written to the mirror disk. If 
data is read from disk, the software has the option of reading from either 
disk, which can improve data access times.
If either disk fails in a fully mirrored system, the system software switches 
to use only the remaining good disk, and system operation continues. 
Status information is available on the Call Processor front panel LEDs to 
indicate when a disk has failed and which disk to replace. After you 
replace a failed disk and restart the system, the software starts bringing 
the new disk up to a fully mirrored state. The system typically takes from 
30 to 90 minutes to complete the mirroring process, depending on the 
amount of data on the master disk. 
						

							Disk Mirroring343
Adding a Mirror DiskIf your system uses a single disk, you can add a mirror disk. The disk you 
add must have at least the same storage capacity as the disk in the 
system. You must obtain a disk mirroring license to convert a single-disk 
system to use disk mirroring. You need a Phillips screwdriver to complete 
this process.
CAUTION:Adding a mirror disk involves a system database backup and a 
system shutdown. 3Com advises that you add a mirror disk only during 
non-business hours.
To add a mirror disk:
1Back up the database on the system.
aSelect Operations > Manage Data.
bClick Backup and specify a location for the backup file.
2Install the disk mirroring license.
aObtain the license key from your dealer.
bSelect Operations > Licenses > Add License.
cType the license key in the two license key fields.
dClick OK.
3Shut down the system by selecting Operations > Reboot/Shutdown > 
Shutdown.
4Install the second disk drive.
aUnlock the disk tray.
bUnscrew the two retaining screws.
cRemove the disk tray.
dConnect the IDE disk cable to the disk drive.
eConnect the power harness to the disk drive.
fFasten the new disk to the disk tray using your Phillips screwdriver and 
the screws provided with the disk.
gReinsert the disk tray.
hScrew in the two retaining screws and lock the disk tray in place.
5Restart the system.
6Verify that the disks begin the mirroring process. 
						

							344CHAPTER 5: SYSTEM CONFIGURATION
On the Call Processor front panel, check the four LEDs immediately under 
the PWR and S1 labels. The LEDs labeled 1, 2, and 3 (Figure 140

NBX MESSAGING
This chapter describes how to configure these features of NBX 
Messaging:
■NBX Voice Mail
■Auto Attendant
■Voice Profile for Internet Mail
If you have installed NBX Unified Communications or a third-party 
messaging system, the NBX Messaging screen is not available in the NBX 
NetSet utility. Follow the documentation for your voice messaging 
system.
NBX Voice MailYou use the NBX Voice Mail tab on the NBX Messaging screen to 
configure system-wide settings for users’ voice mailboxes. When you add 
new users to the system, the system creates a mailbox for each user. 
Users must record a name announcement, a personal greeting, and 
create a password before they can retrieve their messages.
To configure system-wide voice mail settings, select NBX Messaging > 
NBX Voice Mail. See the Help for instructions. 
Ta b l e 5 5
 describes the fields on the NBX Voice Mail tab.
Table 55   Voice Mail Settings
FieldPurpose
Max Number of 
MessagesThe number of messages, regardless of length, that an 
individual mailbox can have. A typical voice message lasts 
about 20 to 30 seconds.
Default: 30 messages 
						

							348CHAPTER 6: NBX MESSAGING
New Msg Retention 
(days)The maximum number of days that a new (unheard) 
message remains in a voice mailbox before the NBX system 
marks it for deletion. However, the message is not deleted 
until the end of this sequence of events:
■The user logs in.
■The NBX system informs the user that the message will be 
deleted.
■The user takes no action to prevent the deletion of the 
message.
■The user logs out.
Default: 30 days.
NOTE: When a user listens to a new message or saves it, the 
system resets the time stamp for that message. The Msg 
Retention value (described next) controls when the system 
marks the message for deletion.
Msg Retention (days)The maximum number of days that a message remains in the 
mailbox after a user has listened to it or saved it. The NBX 
system then marks the message for deletion. However, the 
message is not deleted until the end of this sequence of 
events:
■The user logs in.
■The NBX system informs the user that the message will be 
deleted.
■The user takes no action to prevent the deletion of the 
message.
■The user logs out.
Default: 30 days
Max Incoming Msg 
Length (minutes)The maximum length, in minutes, for any one message.
Default: 5 minutes

Additional Considerations
■The maximum length of a voice mail message is 10 minutes. If 
accumulated messages use up the system’s message storage space 
before individual users reach their capacity limits, you should either 
lower the mailbox settings or upgrade your message storage option. 
Decreasing mailbox settings does not affect data already in storage. 
You can also encourage users to delete old messages.
■To view your system’s current message storage capacity, select 
Operations> Licenses. The system displays the number of NBX Voice 
Mail/Auto Attendant ports and storage space (in hours on an NBX 100 
system). The number of ports determines how many voice mail 
sessions and Auto Attendants can be in use simultaneously.
■Each voice mail extension (port) enables one voice message session. If 
all voice mail extensions are in use, call behavior differs depending on 
the operation. If the Attendant Console is forwarding calls to the Auto 
Attendant, and all voice mail extensions are in use, a caller from 
outside the system hears ringing but no answer until an extension is 
free. If an internal user transfers a caller to voice mail, but no voice 
mail extensions are available, the call rings back to the caller’s 
extension.
■As the administrator, you can configure voice mail extensions, 
settings, passwords, and off-site notification. The NBX NetSet utility 
also offers reports on the status and usage of voice mail ports and 
voice mail storage usage by user. For details, see these sections:
■Voice Mail Extensions
■Voice Mail Passwords
■IMAP (for Integrated Voice Mail)
■Off-Site Notification
■Status
■Port Usage
■User Usage
Voice Mail ExtensionsThe number of voice mail ports on your system determines the number of 
voice mail sessions that can take place at one time. The NBX system 
includes 4 voice mail ports. You can purchase a license for additional 
capacity. Each voice mail port has an extension number. See “Extension 
Settings Overview” in Chapter 2 for more information. 
						

							350CHAPTER 6: NBX MESSAGING
Voice Mail PasswordsTo retrieve voice messages, users must provide their extensions and 
passwords. The password, a 4-digit to 10-digit number, allows access to 
both Personal Settings in the NBX NetSet utility and to voice mail.
■The user can change the password from the telephone or by logging 
in to the NBX NetSet utility 
■If a user forgets his or her password, the administrator can reset it to 
the user’s extension number. See “Security”
 in Chapter 5 for 
information on Security features.
■For more information about the menus and features available to users, 
see the NBX Telephone Guide and the User Help.
IMAP (for Integrated
Voice Mail)NBX Voice Mail uses an Internet Message Access Protocol (IMAP) server. 
Users can also access and manage their voice messages through any 
IMAP-compliant e-mail client. As the administrator, you may need to help 
users to configure e-mail clients.
Voice mail messages appear in a user’s e-mail as mail messages with.WAV 
file attachments. Double-clicking an attachment activates the computer’s 
media player, and the voice message plays through the speakers or 
earphones on the user’s computer. After the user listens to a message, it 
loses its “new” status, but it remains on the server until the user deletes 
it, either through the e-mail client or by accessing voice mail using the 
telephone. The system also deletes messages that are older than the 
system limit (after a warning message to the user).
The computer used to receive messages must support multimedia, that is, 
it must have a sound card and either speakers or headphones.
Users cannot compose new voice mail messages through their IMAP 
e-mail client. They must use their NBX Telephones.
To process both e-mail and voice mail on one computer, the user needs 
either:
■An e-mail client that can connect to two servers
OR
■Two instances of the e-mail client
Each e-mail client has a unique configuration interface, so the following 
procedure is presented in general terms only. See your e-mail client’s 
documentation to determine how to accomplish a specific task.
