VoIP phone calls are usually delivered over a carefully-managed network often running Quality of Service (QoS) and the Session Initiation Protocol (SIP).

An Internet T1 (or T-1 line) is a digital, dedicated local access connection supporting data rates of 1.544 Megabits Per Second (Mbps) that can be channelized into 24 individual channels that each provide 64 Kilobits Per Second (Kbps).

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.

Representative Telecommunication Services: We offer VoIP PBX, IP PBX, US termination, SIP gateway, VoIP gateway, data and Internet T1 (DS1) lines (1.5 Mbps bi-directional transfer upload and download rate), fractional T1 (DS1) circuits (256 Kbps to 1,024 Kbps), bonded (load balanced) T-1 (DS1) lines (3 Mbps to 12 Mbps), T3 (DS3) lines (6 Mbps to 45 Mbps), point-to-point private lines, Virtual Private Networks (VPNs), MPLS (Multi Protocol Label Switching), wide area network (WAN) configurations, inbound and outbound call center services, IP PBX and Hosted VoIP solutions, dynamic and channelized integrated T1 (DS1) lines, Primary Rate ISDN (PRI) service, etc.

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

MPLS VPNs use Multiprotocol Label Switching (MPLS) to set up Virtual Private Networks (VPNs) that can isolate data traffic to provide Class of Service (CoS), Quality of Service (QoS), and ease network administration with minimal network overhead. Layer 3 MPLS VPNs (L3VPNs) use BGP, traffic isolation and Virtual Routing / Forwarding (VRF) for network routing and security. MPLS VPNs are more efficient and robust than IPSec VPN, ATM, MPLS L3VPNs.

Ethernet access to the Internet is quickly becomming a popular service. Ethernet, which is usually thought of as the protocol used to connect computers and servers on a local area network (LAN), is now increasingly being used across metropolitan wide area networks (WANS) to connect corporate LANs to the Internet. The advantage of Ethernet Internet Access service is that connection speeds that range from 1 Megabit per Second (Mbps) to 1 Gigabit per Second (Gbps) can be accessed via the same protocol being used on corporate LANs.

Digital Subscriber Line Service (DSL) has become a very popular Internet access service. This is because DSL uses the existing copper pairs that already exist between most customer premise offices and the local phone company central office (CO). A DSL connection is set up between a DSL modem at the customer premise and a DSL access multiplexer, or DSLAM, at the phone company central office. Both voice and data can be run across the same DSL connection by using a filter to separate voice traffic from Internet traffic.

Wireless Internet is a new way to access the Internet at high speeds from anywhere in the United States. Wireless Internet is delivered via terrestrial transmitters and receivers or by satellites that orbit the Earth while transmitting and receiving high frequency radio internet data to a small dish located at the customer premise. Two-way satellite radio system is reliable, easy to set up and is mobile. You can move the subscriber terrestrical or satellite dish and re-connect with ease.

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).
