With Managed VoIP service, you get advanced features including the ability to manage calls through a Web portal with features such as findMe/follow me, remote user, voice mail sent to email, and selective forwarding.

A T1 local access connection to the Internet that can be configured to carry either 24 digitized data channels or one aggregated concatenated data channel at a rate of 1.544 Megabits Per Second (Mbps) that is connected via a T1 Wan Interface Card (WIC), Channel Service Unit / Data Service Unit (CSU/DSU), and Internet router.

VoIP over Internet Protocol (IP), or VoIP, is a managed voice and Internet solution for businesses that falls into the industry niche referred to as IP Centrex (a feature-rich hosted analog voice solution), or Hosted Private Branch Exchange (PBX) that provides many features and capabilities that transform business communications beyond what traditional voice and data networks can offer.

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.

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 provides a great local access medum to connect LANs to the Internet and is quickly becoming the access method of choice were it is available.

Digital Subscriber Line (DSL) connects end users (subscribers) to the Internet via a plain old telephone service (POTS) line that uses an existing copper pair but has been sped up by a Digital Subscriber Line Access Multiplexer (DSLAM) located at the service provider centeral office (CO) to form a continuous digital high-speed data connection from the customer premise to the Internet.

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).
