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.
T
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.
Trunk Level 1 (T1) - a high-speed (1.544Mb/s) digital telephone line with the equivalent of 24 individual 64Kb/s channels that are joined via time
division multiplexing. A T1 line can be used to transmit voice or data, and many are used to provide connections to the Internet. T1 is the North
American equivalent of an E1 line.
U
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.
V
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. The 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.
W
Wide Area Network (WAN) - a communications network used to connect computers and other devices across a large area.
Windows Internet Naming Service (WINS) - a database with all PC hostnames and IP addresses connected to them in the TCP/IP environment.
