MPLS VPNs transport layer 2 packets across the network and encapsulate transport protocols such as ATM, Ethernet, and SONET, allowing MPLS networks to seemlessly upgrade and replace legacy layer 2 networks without requiring network reconfiguration or using protocols higher than layer 2. In comparison, layer 3 VPNs must use the layer 3 Internet Protocol (IP).

An Internet T1 (sometimes spelled T-1) is a high speed telecommunication line that can carry 24 digitalized voice channels, or it can carry data at a rate of 1.544 megabits per second.

Hosted VoIP eliminates the need to purchase or lease expensive PBX equipment to gain advanced calling features such as voicemail, automated attendants, extension dialing, call forwarding, call park, or call transfer. Hosted VoIP also eliminates the need to obtain service from multiple carriers for local and long distance calling, PBX tie-lines, private lines, etc. The service also includes Internet access and Quality of Service (QoS) to guarantee voice quality all on one invoice. Hosted VoIP offers freedom from legacy equipment costs, eliminates reliance on slow-moving traditional phone companies, multiple bills, and offers flexibility to deliver customized user productivity solutions for your company.

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.

A major feature of Internet over Ethernet is the ease in which you can upgrade from 1 Mbps to 1 Gbps. Simply call your Internet Service Provider (ISP) and ask for an upgrade and it can be provisioned almost in real time. This service is the future of Internet access for the foreseable future.

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.

Exlpore why Ethernet is probably the next killer broadband delivery platform.

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.

MPLS can be used to create highly-scalable IP networks with layer 2 level security as well as easy network configuration, management, and provisioning.
