TAPI Settings341 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 ) indicate disk status. Figure 140 Disk and Power LEDs Ta b l e 5 4 describes the possible states of the LEDs.

Disk Mirroring345 Verifying a Failed Disk DriveIf either disk fails while in a fully mirrored state, the system continues to operate. The disk LED states described in Table 54 indicate which drive has failed. In addition, the Disk Status window (Figure 141 ) in the NBX NetSet utility shows the status of your disk drives. Figure 141 Disk Status Window To verify the status of a disk drive, select Reports > System Data > Disk Status. See the Help for information on verifying disk status.

346CHAPTER 5: SYSTEM CONFIGURATION Reverting to a Single-Disk SystemIf the disk mirroring is currently active, you can convert the system to operate with a single disk. You need a Phillips screwdriver to complete this process. To revert to a single-disk system: 1Use Table 54 (Disk LED States) to determine which disk is the mirrored disk. 2Shut down the system down using the NBX NetSet utility and selecting Operations > Reboot/Shutdown > Shutdown. 3Remove the mirrored disk drive: aUnlock the disk tray. bUnscrew the two retaining screws. cRemove the disk tray. dDisconnect the disk data cable from the mirrored disk drive. eDisconnect the power harness from the mirrored disk drive. fUnfasten the mirrored disk from the disk tray using the 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. 4Restart the system. 5Remove the disk mirroring license from the NBX NetSet utility: aSelect Operations > Licenses > Remove License. bIn the Remove License dialog box, select Disk Mirroring License from the list. cClick OK.
6 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 Maximum: 10 minutes Voice Mail Compression FormatThe system uses ADPCM as the voice mail compression format for voice prompts and messages. On Disk Voice Mail FormatThe system uses ADPCM as the compression format for voice prompts and mail on your disk. Disable AA Transfer PromptEnables or disables the transfer prompt (“Please hold while your call is transferred”) when a call is transferred from the Auto Attendant. Default: disabled (unchecked) Table 55 Voice Mail Settings (continued) FieldPurpose
NBX Voice Mail349 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.
