392 APPENDIX D: CONNEXTIONS H.323 GATEWAY
configuration is appropriate if the firewall, which separates Internet
and intranet, is either unnecessary or is required by company policy.
ConneXtions
Software
You use the NBX Resource Pack CD to install ConneXtions software. The
ConneXtions software performs the protocol conversions between an
NBX system and the international H.323 standards. To a system
administrator, H.323 ports look like PSTN line ports. Both have extensions
and are configured the same way but have different license requirements.
The NBX Resource Pack CD is also required to change H.323 gateway
parameters after installation. A dealer who wants to explore possible
hardware incompatibilities by running ConneXtions from a substitute
laptop must reinstall ConneXtions on the laptop at each site.
Preparing for
Installation
Before you install a ConneXtions H.323 Gateway:
■ Assemble system information.
■ Check for the G.723 convertor (optional).
■ Verify and install the NT Service Pack (Service Pack 4) (if required).
■ Assemble permissions, licenses, and notifications.
Do not uninstall the current version. You would remove the current
settings.
Assembling System
Information
ConneXtions is installed through an InstallShield wizard. It presents a
series of dialog boxes that request specific permissions and configuration
information. Assemble this information before you begin an installation:
■ NBX administrator login name: <administrator>
■ NBX administrator password: <xxxxxxxx>
■ NBX H.323 software and associated port licenses.
■ Caller ID label for outgoing calls. The default is the caller’s extension.
Use the main office telephone number (10 digits in the United States).
■ NBX system name. Supply the name that H.323 callers see when they
connect to the Auto Attendant.
■ The TCP or UDP port ranges for use with a firewall, if any.
