same company, usually through an Ethernet hub.

IP Address. A unique 32 bit address that identifies a net-

work device is connected to the network via TCP/IP.

IVR. Interactive Voice Response enables you offer ser-

vices, such as Pre-paid calling cards and Post-paid

accounts to your customers.

LAN. Local Area Network. A local area network that

carries data between workstations in the same loca-

tion. Workstations in a LAN are connected togeth-

er— 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 chas-

sis and other components.

Maintenance Mode. A CLI module which provides util-

ities for maintaining the system.

Monitor Module. A CLI module which provides a set of

utilities to monitor the network and all system com-

ponents.

Null modem cable. A 9-pin cable used to connect the

Tenor DX to a PC’s asynchronous console port.

PacketSaver. A packet multiplexing technology which

reduces the amount of IP bandwidth require to sup-

port multiple calls flowing between two networks.

PBX. Private Branch Exchange. Telephone switch locat-

ed on a customer’s premises that establishes circuits

between users and the PSTN (public network).

Power Inlet. Inlet for which you insert the supplied AC

power cord. The unit requires a 110-220 VAC.

PSTN. Public Switched Telephone Network (also known

as Central Office). Telephone Company Switching

facility.

RJ-45. A CAT 5 cable used to connect the Tenor DX to

an Ethernet, Line Circuit or Trunk Circuit.

RADIUS. When using IVR, the RADIUS (Remote Au-

thentication Dial-In User Service) is used for authen-

ticating and authorizing user access to the VoIP

network.

SelectNet™. The next generation of TASQ technology;

the functionality monitors your data network for jit-

ter, latency, and packet loss, and transparently

switches customer calls to the PSTN when required.

SIP. A signaling protocol used to establish a session on

an IP network.

SNMP. Simple Network Management Protocol (SNMP)

is the standard protocol used to exchange network in-

formation between different types of networks.

Subnet Mask. An IP address that determines how an IP

address is divided into network and host portions ac-

cording to the bits.

TCP/IP. Transmission Control Protocol/Internet Proto-

col. TCP/IP is a standard communications protocol

divided into seven layers of activity. Each layer de-

fines 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 com-

munication protocol. TCP (layer 4) does the actual

transport of data; IP (layer 3) sets the rules for mov-

ing the data from one end of the network to another.

TCP/IP uses an IP address to identify a location for

specific network devices.

Transition Module. The RJ-48 ports on the rear of the E1,

T1 or DS1 card used for connectivity to the network.

Trunk Group. A collection of T1 or E1 channels used to

connect the Tenor DX to the network or another

piece of equipment.

WAN. Wide Area Network. A number of LANs connect-

ed together through a long distance communications

medium. For example, your company 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 the public network, it is consid-

ered a WAN. As a result, intra-corporate information

is passed through the data network from one LAN to

another LAN site in a remote location.
