Remote Testing - remote connection from the Epygi Support office to the customer’s Quadro for testing and/or for troubleshooting.

Router - A device that determines the next network point to which a data packet should be forwarded enroute toward its destination. The router is

connected to at least two networks and determines which way to send each data packet based on its current understanding of the state of the

networks it is connected to. Routers create or maintain a table of the available routes and use this information to determine the best route for a given

data packet

RSA - is an asymmetric key system. It must be available on both sides of the VPN and generates on each side a different pair of keys, a private and

a public key.

Security Parameter Index (SPI) - is an index to keep VPN tunnels distinct. A security association is defined by destination, protocol and SPI.

Without the SPI, connections to the same gateway using the same protocol would not be distinguishable.

Session Initiation Protocol (SIP) - is an application-layer control protocol that can establish, modify and terminate multimedia sessions or calls. SIP

is increasingly used for Internet telephony signaling, in gateways, PC phones, softswitches, and softphones, but it is not limited to Internet telephony,

and can be used to initiate and manage any type of session, including video, interactive games, and text chat.

Signaling - a process of sending a transmission signal over a physical medium for communication.

Silence Suppression - a method that allows disabling RTP packet transmission when there is no voice activity. This feature helps to avoid extra

traffic when the RTP stream doesn’t contains voice data.

Simple Network Management Protocol (SNTP) - the Internet standard protocol developed to manage nodes on an IP network.

SIP address - unique address of the users registered on the SIP server. The address can be used to connect the user. The full SIP address has the

following format: “display name” <username@ipaddress:port>.

SIP server - this server is used for registering users. It gives a possibility to make IP connections between users registered on the same SIP server.

Software - PC programs.

Software PBX - a telephone system that converges voice and data on an industry-standard computing platform and uses computer telephony

components that conform to industry standards. Since they conform to industry standards, software PBXs are interoperable with third-party systems

and CT components. Conformance also allows software PBXs to run third-party enhanced applications such as desktop call control, graphical voice

mail, automatic call distribution (ACD), IP gateways, follow-me call forwarding, unified messaging, and CRM integration.

Speed Calling - a service that allows making a personal address book for every Quadro user. A simple digit combination can be assigned to any

destination phone number.

Transfer - a service giving a possibility to readdress incoming calls. Call Transfer can be conditional (with consultation) and unconditional (without

consultation).

Transmission Control Protocol (TCP) - a connection-oriented transport layer protocol that provides reliable full-duplex data transmission. TCP is

part of the TCP/IP protocol stack.

Transmission Control Protocol/Internet Protocol (TCP/IP) - is a networking protocol that provides communication across interconnected

networks, between computers with diverse hardware architectures and various operating systems.

Trunk: - is a communications channel between two points, typically referring to large-bandwidth telephone channels between switching centers that

handle many simultaneous voice and data signals.

UDP - a connectionless transport layer protocol in the TCP/IP protocol stack. UDP is a simple protocol that exchanges datagram without

acknowledgments or guaranteed delivery, requiring that error processing and retransmission be handled by other protocols.

Universal Serial Bus (USB) - is an interface with a protocol that is designed to handle a broad range of devices - telephones, modems, printers, etc.

Upstream- in communications, there are two circuits - one coming toward you and the other going away from you. Upstream is another term for the

name of the channel going away from you.

URL - an identifier used to locate content that is transported via the HTTP protocol.

Username - identification name of the user. Usually used for registration and login.

VCI - parameter used to configure ATM settings and is usually given by the Internet provider.

Virtual Private Network (VPN) - connects two local networks (intranets) over the insecure Internet securely. VPN routers manage authentication

between servers and clients and handle data encryption for the connection. Only authorized users can access the network and the data exchange

cannot be intercepted. A VPN includes authentication and encryption to protect data integrity and confidentiality. VPNs are “virtual” in the sense that

individuals can use the public Internet as a means of securely accessing an internal network. Once the VPN connection is established, users have

access to the same network resources, addresses, and so forth as if they were connected locally. VPNs are “private” because the data is encrypted

between two VPN gateways. Encryption makes it very difficult for anyone to intercept data and capture sensitive information such as passwords.

Voice mail - a brief message that external users can leave for the Quadro users in the event that nobody answers the call.

Voice Mail System (VMS) - a feature providing the possibility of leaving brief voice messages at the unavailable or busy Quadro extension’s

mailbox.

Voice mailbox -is the mailbox where voice mails are collected.

Voice message - help messages that are played to the user giving a hint on how to manipulate the menus within Quadro using the phone handset.

Voice Over Internet Protocol (VOIP) - technology used to transmit voice conversations over a data network using the Internet Protocol. This

provides ability to carry normal telephony-style voice over an IP-based internet with POTS-like functionality, reliability, and voice quality.

VPI - parameter used to configure ATM settings usually given by the Internet provider.

Wide Area Network (WAN) - a communications network used to connect computers and other devices across a large area.
