Chapter 1
Videoconferencing Basics
In the past all you needed to make a video call was a phone number (or two) and a line
rate. With the advent of new standards, you can now bypass the phone company
altogether, but it takes a little understanding.
Calls using phone numbers and long distance carriers are known as Wide Area Network
(WAN) calls. These calls use the H.320 standard. A new standard, H.323, allows
companies to place calls using their computer network. This Local Area Network
(LAN) system uses the Ethernet that a company already has in place to transfer the
video data—thus avoiding any phone company difficulties, as well as the per call phone
charge.
LAN (H.323) calling
Naming conventions
IP addresses and aliases
Each computer on a network, including your WG500 system, is called an endpoint.
Each endpoint is assigned an Internet Protocol (IP) address. This IP address is used when
making a LAN-based call. It has the form of xxx.xxx.xxx.xxx. This system works quite
smoothly, but it is often difficult to remember IP addresses. Thus, aliases have been
developed as an easier way of accessing other endpoints. For example, “Bob_Smith” is
an alias that can be used to address the computer in Bob’s office, rather than entering
his IP address of 255.146.208.190. This technique is the same system that allows e-mail
to use names and not IP addresses.
Typically, your IP alias will be the same as your e-mail address. However, you should
contact your system administrator to verify this.

Installation Guide
Chapter 1. Videoconferencing Basics
1.2
H.323 IDs
One potential problem is that not all computers have access to all aliases, but a solution
has already been devised. An alias, known to the videoconferencing system used when
making LAN based calls, is called an H.323 ID. It looks like an IP alias and works the
same way, but is administered and only used by the videoconferencing system. It is a
good idea to make your IP alias and your H.323 ID the same.
E.164 addresses
Another technique for LAN addressing is to assign a number to each system. This
number looks like a phone number, and therefore contains only digits and the * and #
symbols. This number is known as an E.164 address.
Gatekeepers
Videoconferencing looks better with more bandwidth given to it. However, bandwidth
is limited, and if all the bandwidth in a LAN is used for videoconferencing, the other
computer applications will suffer. In order to limit the amount of bandwidth used for
videoconferencing, many corporations are installing gatekeepers. A gatekeeper is
another node on the Ethernet that simply keeps track of how many calls are currently
active and limits new calls accordingly. When setting up a new videoconferencing
system, such as a WG500, the system must be aware of any gatekeepers on the LAN. A
gatekeeper is optional, or there could be many in a large system.
Part of the WG500 setup process is to indicate to the video-conferencing system which
gatekeeper, if any, it is to use (see Chapter 3). The gatekeeper can also help with the
address translations and is, in fact, where the H.323 IDs and E.164 addresses get
converted to IP addresses.
Gateways
A LAN-based (H.323) system can call a WAN-based (H.320) system but there needs to
be something to make the protocol translation—a gateway. That same gateway can be
used to accept an incoming call from a WAN-based system via the phone lines and
route that call to a LAN-based system using the company-wide Ethernet.
The gateway complicates the call only in that the phone number must include the phone
number of the WAN device as well as the LAN address of the LAN device. Therefore
the dialing procedure is slightly more complex. See Chapter 4, “Using the Connection
Interface window.”
There are several manufacturers of gateways and your WG500 system must know the
address and the manufacturer of the gateway(s) it is to use. This information will be
entered into the Advanced Configuration program (see Chapter 3).

WAN (H.320) calls 1.3
SmartStationTM
WAN (H.320) calls
Wide Area Network (WAN) calls are placed using traditional telecommunications
methods, such as ISDN lines or DDM networks. The WG500- 384i uses one three ISDN
BRIs to place calls to other videoconferencing endpoints at speeds up to 384 Kbps.
Depending on the switch type used by your telecommunications company, you may
have to know your SPIDs and DNs. please refer to Appendix A.
