New 3Com Model 3102 Business Telephone
The 3Com Model 3102 Business Telephone is a new design of the Business Telephone. It shares the same core capabilities as previous models with a number of improvements to its appearance and design, including:

• Headset Jack – You can connect a headset directly to the Model 3102 Business Telephone. A programmable button on the telephone enables or disables headset operation.


• The phone has an enhanced full-duplex speakerphone with superior voice quality.


• The new, one-piece stand offers 15- to 45-degree desk adjustments as well as a wall-mount position.


• All 18 programmable buttons include a status light (LED).


• Replaceable bottom bezels will be offered for localization of button names.


• New Model of the Single-Port Analog Terminal Adapter (3C10400)

The new model operates with all of the same features as the previous models, plus these two new capabilities:
• Power over Ethernet (PoE) – The new model can supply power to devices that are compliant with the IEEE 802.3af standard.


• Diagnostic Port – The new model has a 9-pin RS232 connector (DB9) to which you can connect your PC using the appropriate cable and a terminal emulation software package such as Hyperterm.

Progress Indicators
During backup or restore your NBX database, or during your upgrade of the NBX system software, you now see progress bars in the NBX NetSet™ utility. Also, you can now cancel a backup or upgrade operation that is in progress.

Saving the Most Recent Backup File
You can now click a button on the Manage Data tab to save the most recent backup file. This shortcut enables you to save the most recent backup file to more than one location without performing another backup.

System Alert While a File System Check Is Being Performed
During a reboot operation, if a file system check (FSCK) is required, the NBX system now alerts you to this fact by flashing the Call Processor S1 and S2 status lights in an alternating pattern.

Enhanced Caller ID Information
When a call is forwarded, redirected, or transferred to you, the display panel on your NBX Telephone now shows caller ID information for the original caller and for the person who is forwarding, redirecting, or transferring the call to you.

NBX System Settings
3Com Networked Telephony Technical Bulletin Page 11
Some NBX system settings have been moved to a new Audio Settings screen (NBX NetSet > System Configuration > System Settings > Audio Settings). The new screen includes these configurable settings:

• System-Wide Silence Suppression


• System-Wide Silence Suppression on VTL Calls


• Audio Compression on VTL Calls


• NBX Handset Acoustic Echo Suppression (new setting)


• Analog Line Cards Additional Echo Suppression (new setting)


• Digital Line Cards Additional Echo Suppression (new setting)
  See implementation instructions on the screen.

Enhanced Status of Analog Line Card Ports
The status screen for Analog Line Card Ports now includes information about the most recent five completed calls.

D-Channel Status Information for ISDN PRI
If you have a Digital Line Card configured for ISDN PRI operation, the Span Status screen in the NBX NetSet utility now includes status information about the D channel. You can verify whether the D channel is Online, Offline, or in an Unknown state.

Licensing
Starting with Release 4.2, the NBX system software requires a license. Upgrades from previous releases must be done with this requirement in mind. See the NBX Administrator’s Guide for details.

Remote NBX Device Behind a Home Router or Firewall
You can now have a single NBX device such as an NBX Telephone in your home, if you connect to the Internet through certain home router devices.

Telnet
You can now establish a telnet session between your PC and the NBX system. This ability, which requires administrator login ID and password, can be turned on or off by the system administrator. By default, this setting is turned off.

Purging Voicemail
When you purge your NBX database, you now have the option of purging all voicemail from the NBX system. Later, if you restore your database from a prior backup, you can choose whether or not to restore voicemail if it is included in the backup.

Redirecting TAPI Calls
A TAPI Route Point is a virtual device (new in R4.2) that you can create using the NBX NetSet utility. It has an extension and can receive and queue multiple simultaneous calls for application-driven redirection to other telephone numbers. A SuperStack 3 NBX system allows up to 400 calls to be queued by TAPI Route Points. An NBX 100 system allows 50 calls to be queued. You can configure TAPI Route Points to accept internal and external calls and queue them until they can be redirected by TAPI or until the calls time out. Calls that are redirected go to a destination specified by TAPI applications that are external to the NBX system. Calls that time out are sent to the call coverage point of the TAPI Route Point. TAPI Route Points can be useful if you are using the NBX system in a call center environment. Calls to other devices that can be monitored by TAPI, such as Analog Terminal Adapters, Analog Terminal Card ports, NBX Telephones, and Hunt Groups can also be redirected by TAPI-enabled applications.
