of a PBX into a private network in order to elim-
inate toll charges.
I
Internet. A packet based network which transports
voice/video/data over TCP/IP.
Intranet communication. Communication within
the same company, usually through an Ethernet
hub.
IP Address. A unique 32 bit address that identifies
a network device is connected to the network via
TCP/IP.
IVR. Interactive Voice Response enables you offer
services, such as Pre-paid calling cards and
Post-paid accounts to your customers.
L
LAN. Local Area Network. A local area network
that carries data between workstations in the
same location. Workstations in a LAN are con-
nected together— typically by an Ethernet
hub— to share information.
LEDs. Indicators as to the status of the chassis and
other components of the system. LEDs appear
on the front of the unit.
P
PacketSaver. A packet multiplexing technology
which reduces the amount of IP bandwidth re-
quired to support multiple calls flowing between
two networks.
PBX. Private Branch Exchange. Telephone switch
located on a customer’s premises that establish-
es circuits between users and the PSTN (public
network).
PSTN. Public Switched Telephone Network (also
known as Central Office). Telephone Company
Switching facility.
R
RJ-11. A CAT 5 cable used to connect the Tenor AS
to an FXO or FXS interface.
RADIUS. When using IVR, the RADIUS (Remote
Authentication Dial-In User Service) is used for
authenticating and authorizing user access to the
VoIP network.
S
SelectNet ™. Monitors your data network for jitter,
latency, and packet loss, and transparently
switches customer calls to the PSTN when re-
quired.
SIP. Signaling protocol used to establish a session
on an IP network.
SNMP. Simple Network Management Protocol
(SNMP) is the standard protocol used to ex-
change network information between different
types of networks.
Subnet Mask. An IP address that determines how an
IP address is divided into network and host por-
tions according to the bits.
T
TCP/IP. Transmission Control Protocol/Internet
Protocol. TCP/IP is a standard communications
protocol divided into seven layers of activity.
Each layer defines a different aspect of how two
devices should talk to each other (i.e., when a
network device should send/receive data). For
example, layer one is the physical means of
communications (e.g., modem), whereas layer 3
is the network type (e.g, Internet). For TCP/IP, it
is a combination of two layers of communica-
tion protocol. TCP (layer 4) does the actual
transport of data; IP (layer 3) sets the rules for
moving the data from one end of the network to
another. TCP/IP uses an IP address to identify a
location for specific network devices.
Tenor Monitor. A GUI interface which provides a
set of utilities to monitor the network and all sys-
tem components.
W
WAN. Wide Area Network. A number of LANs
connected together through a long distance com-
munications medium. For example, your com-
pany may have a LAN in New York, a LAN in
Tokyo, and a LAN in Los Angeles. When these
sites connect together over the data network or
