TSP includes a plug-in telephony adapter architecture allowing plug-in adapters to
be developed for new telephony servers without the need to customize underlying
code.
Adapter application
An adapter required to run between the TSP partner Web server and the bridge to
convert the generic API calls to the bridge's own API calls.
Active Speaker
The participant speaking in a session, identified by a blinking icon.
B
Balancer
See Load balancer.
Bridge
A self-contained server that supports telephony conferencing, i.e., all the software
is contained inside and is provided by the vendor.Bridge Call ID
All calls have an ID assigned by the bridge.
C
Channel
A communication channel, i.e., WebEx Meetings servers and the bridge. A channel contains the
adapter itself.
Computer name
A unique name assigned to a computer (hardware) on the network.
CSV
A table of Comma Separated Values. Comma separated text data format.
D
Dedicated adapter
An adapter that works with a single CACS server.
DHCP
Dynamic Host Configuration Protocol. IP addresses and related information are
dynamically configured. TCP/IP networks are easily configured using DHCP. Duplicate
addresses are eliminated, and IP addresses are used effectively by centrally managing
their allocation.
DNS
Domain Name Service. A system that creates associations between host names and
network addresses on a network.
Domain Name Service
See DNS.
E
External ID
See Message ID.
External Call ID
The ID that the TSP server gives each call.
F
Fail-over feature
The WebEx Meetings TSP architecture supports redundant telephony servers to allow meetings in
progress to be moved to a backup server.
Firewall
A security gateway on the Internet. On the Internet, internal organization networks
are constantly affected by unauthorized access from outside. In order to prevent this,
a firewall is placed between external and internal networks to filter all incoming
packets according to the provisions of the organization's security policy.
Protects private network security with functions to relay only specific protocol from
the Internet to the private network.
Full system operation
An operational command that applies to an entire system.
H
HTTP
HyperText Transfer Protocol. One transmission method that is used to pass through a
firewall, this text transfer protocol is used on a Web server. A communication protocol
used for transactions between Web servers and Meeting Managers on the Internet.
I
IP Address
A unique 32-bit network address allocated to every node on the Internet.
ISP
Internet Service Provider. A company that provides connection service to the
Internet. Also called an "Internet provider" or simply "provider."
L
Load balancer
A device that evenly distributes requests to TSP adapters based on specified
criteria.
Meeting Center product for teleconferencing service providers.
Message ID
For each message passed between the TSP server and the adapter, it is given an
ID.
N
NBR
Network Based Recording.
P
Permanent connection
A connection method type where communication paths are permanently established in
order to facilitate event notifications to a host system. The other connection types
are connect-when required and Remote Access Service (RAS).
R
Redundancy configuration
WebEx Meetings TSP architecture is designed to support different system fail-over and
redundancy or duplicated configurations.
S
Server configuration file
The adapter's host name and HTTP port number redefined in the
WebEx Meetings server configuration file.
Server redundancy
WebEx Meetings TSP architecture is designed to support different system fail-over and
redundancy or duplicated configurations.
Silent Join
A feature that allows a Sales Manager to invisibly monitor a session without
participating, or informing participants.
SSL
Secure Socket Layer. A protocol standard advocated by Netscape Communications that
provides secure communication procedures for applications communicating in TCP/IP.
Sub-conference
A separate session that is created outside a main session by participants of the
main session.
System
A general term for a client or server.
T
Task
A single operational unit.
TCP/IP
Transmission Control Protocol/Internet Protocol. A world-standard LAN-based network
protocol developed mainly by the United States Department of Defense.
Transaction ID
A sequence number.
TSP
A teleconferencing service provider.
TSP Server
A hardware box that runs the WebEx Meetings TSP telephony API.
TSP Server Failover
A state in which the TSP Server does not respond to call-in's and call-out's of a
session and which prompts WebEx Meetings to switch the ongoing session to a redundant TSP
server.
U
UI
User interface.
V
VPN
Virtual Private Network. A virtual private network that seethe Internet. A network
that prevents eavesdropping by building virtual private communication lines between
communicating parties on the Internet and sending communication data after encrypting
it. A normal firewall is set up and security is protected on the Internet through
protocol tunneling and encryption.
W
WAN
Wide Area Network. A communication network that connects geographically distant
locations.
WBS
WebEx Meetings Business Suite - This acronym refers to the version of the WebEx Meetings Site.
