One of the advantages of VoIP is that voice and Internet services are delivered over the same local loop access circuit using the Internet Protocol (IP).

An Internet T1 connection can support up to hundreds of desktop computers depending upon the applications and bandwidth being utilized.

Voice over Internet Protocol (VoIP) service that sets up telephone calls over the Internet that are often billed at a flat rate and leverage subscribers existing broadband Internet connection. This saves money in that only one connection is needed for both voice (phone) and data (Internet) service.

The ADSL downstream receiving rate from the Internet usually varies from 1.5 to 9Mbps while the upstream sending rate usually varies from 16 to 640 Kbps.

Ethernet can be used to connect twisted copper pair networks and to connect fiber optic cable networks.

Multiprotocol Label Switching (MPLS) is a data network protocol that uses Class of Service (CoS) to prioritize different types of data packets across a shared network to facilitate the convergence of voice, video and data applications.

Ethernet is the most widely-used data network protocol today. Standardized as IEEE 802.3, the Ethernet protocol is used for local area networks (LANs) at the Layer 1 (Physical Layer) and Layer 2 (Data Link Layer) of the OSI networking model.

DSL has become a widely-accepted and increasingly reliable method of delivering phone service and providing Internet access that saves end users money because both voice and data are delivered across the same plain old telephone serivce (POTS) line. However, the distance to the local phone company central office where the copper POTS line is connected from the customer premise to the DSLAM will determine the potential speed of the DSL connection.

Telecom Links reveals the secrets of telecom technology from the first radio to the latest fiber optic technologies.

If you are looking for clear, concise definitions of telecommunication terms and explanations of telecom services, especially how they are used and how they work, TelecomLInks is a great place to start.

Layer 2 MPLS VPNs (L2VPNs) are similar to Frame Relay, Asynchronous Transfer Mode, or point-to-point Wide Area Networks (WANs).
