1 Introduction This User Manual is provided to help you make the best use of your TANDBERG Gatekeeper.
A Gatekeeper is a central part of an H.323 infrastructure. It provides address translation and
controls access to the network for H.323 terminals, Gateways and MCUs. The Gatekeeper
also provides other services to the terminals, Gateways and MCUs such as bandwidth
management and locating Gateways.
A Gatekeeper is also a key component of TANDBERG’s ExpresswayTM firewall traversal
solution. Used in conjunction with a TANDBERG Border Controller it allows calls to be made
into and out of a secured private network.
The main features of the TANDBERG Gatekeeper are:
Automatic discovery and manual registrations of H.323 terminals, gateways and
MCUs.
Registration of H.323 ID, E.164 aliases and services.
Secure traversal of any firewall or NAT.
URI dialing.
Supports up to 1000 registered devices and services.
Supports up to 100 neighboring zones.
Up to 200 active calls.
Up to 100 traversal calls.
Flexible zone configuration with and without prefixes.
Can function as a leaf Gatekeeper or as a master Gatekeeper in a Gatekeeper
hierarchy.
Can be used to control the amount of bandwidth used both within a zone and to
neighboring zones.
Can limit total bandwidth usage and set maximum per call bandwidth usage with
automatic down-speeding if call exceeds per-call maximum.
Can be managed with TANDBERG Management Suite 9.0 or newer, or as a
standalone system with RS-232, Telnet, SSH, HTTP and HTTPS.
Embedded setup wizard on serial port for initial configuration.
Note that features may vary depending on software package.
