Interactive Voice Response (IVR)

IVR is a telephony technology that can read a combination of touch tone and voice input. It gives users the ability to access a database of information via phone. A typical IVR system has several menus of prerecorded options that the caller can choose from. While many choices are as basic as choosing a number, some options may require the caller to speak detailed information such as his name or account number. This input is read by the IVR system and is used to access the appropriate information in the database.

Internet Protocol (IP)

A protocol used to send data over a network. These are currently set to IPv4 meaning 4 octets ranging from 0-255. The public internet takes up a majority of these addresses, but there are certain ranges reserved for private LANs.

This refers to a company that produces hardware to be marketed under another company's brand name.


P

Packet

A unit of data transmitted over a network. This is a small amount of computer data sent over a network. Any time you receive data from the Internet, it comes to your computer in the form of many little packets. Each packet contains the address of its origin and destination, and information that connects it to the related packets being sent.

Park

Parks a call in a reserved extension (park slot) and allows the call to be retrieved from another extension.

POE (Power over Ethernet)

A method of providing power to a network device over the network cabling, eliminating the need for a power supply.

Port

Ports can describe two different devices.

An Internet port.

This is a number that indicates what kind of protocol a server on the Internet is using. For example, Web servers typically are listed on port 80. Web browsers use this port by default when accessing Web pages

A hardware port.

This refers to any one of the ports that are on the back of a computer where devices can be hooked up (like a keyboard, mouse, printer, etc). Some common ports found on today's computers are USB, Firewire, and Ethernet.

PRI (Primary Rate Interface)

ISDN service provides 23 64-Kbps B (Bearer) channels and one 64-Kbps D (Data) channel (23 B and D). The D Channel is used for control in signaling information.

Private Branch Exchange (PBX)

An in-house telephone system that connects extensions and the Public Switched Telephone Network.

Public Switched Telephone Network (PSTN)

This is the global circuit-switched telephone network. It is similar to the Internet. However, on the Internet packets of data are sent and received using Internet protocol over a network.


Q

Quality of Service (QoS)

The ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow.


R

Redundant Array of Independent Disks (RAID)

This is a method of storing data on multiple hard disks. When disks are arranged in a RAID configuration, the computer sees them all as one large disk. However, they operate much more efficiently than a single hard drive. Since the data is spread out over multiple disks, the reading and writing operations can take place on multiple disks at once. This can speed up hard drive access time significantly. Multiple hard drives may not improve hard disk performance as much as multiple processors may enhance the CPU performance, but it is based on a similar logic.

Real-Time Protocol (RTP)

A standardized packet format for delivering audio and video over IP networks.

Router

A networking device that connects multiple networks together, such as a local network and the Internet.

S

Server

Any computer in a network that provides users access to files, printing, communications, etc.

Server Time

This is the time set on the server where the phone or device is located. The server time for IPitomy’s IP PBX system is synched to time.nist.gov server time.

Session Initiation Protocol (SIP)

A signaling protocol that establishes data sessions. For example when making a call from one extension to another on a VoIP phone system SIP sets up the call and creates the connection between the two extensions.

Smart Personal Console (SPC)

This user-friendly Web page gives a person the ability to set basic phone features (mailbox settings, phone key settings, call forwarding, etc) from anywhere. Additionally, the user can check their voicemail and call logs from the SPC.

Stateful Packet Inspection (SPI)

A stateful inspection is a firewall architecture that works at the network layer. Unlike static packet filtering, which examines a packet based on the information in its header, a stateful inspection tracks each connection traversing all interfaces of the firewall and makes sure they are valid.

Static IP

An IP address that does not change.

Subnet Mask

A subnet mask is a number that defines a range of IP Addresses that can be used in a network. Subnet masks are used to designate subnetworks, or subnets, which are typically local networks LANs that are connected to the Internet. Systems within the same subnet can communicate directly with each other, while systems on different subnets must communicate through a router. Therefore, subnetworks can be used to partition multiple networks and limit the traffic between them.

Switch

A network device that connects network segments. These come in POE and non-POE varieties.


T

T1

A dedicated digital voice circuit that has 24 channels. This point-to-point circuit delivers 1.544 Mbps of bandwidth.

A simple protocol to transfer files. IPitomy uses this method in regards to phone firmware and configuration files. http://en.wikipedia.org/wiki/Trivial_File_Transfer_Protocol

Time to Live (TTL)

This refers to an aspect of the Internet Protocol. TTL is used when a "ping," or a request for a response, is sent to another computer, such as a server. The TTL represents the number of hops, or servers in different locations, the request can travel to before returning a failed attempt message.

Transfer

Sends a call to another extension.

Trunk

A communications channel between two points.

Transmission Control Protocol (TCP)

Packets sent via this method are verified end to end.


U

Upload

While downloading is receiving a file from another computer, uploading is the exact opposite. It is sending a file from your computer to another system. It is possible to upload and download at the same time, but it may cause slower transfer speeds, especially if you have a low bandwidth connection. Because most files are located on Internet servers, people generally do a lot more downloading than uploading.

Uniform Resource Locator (URL)

A URL is the address of a specific Web site or file on the Internet. It cannot have spaces or certain other characters and uses forward slashes to denote different directories. Some examples of URLs are http://www.cnet.com/, http://web.mit.edu/, and ftp://info.apple.com/.
