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 (also spelled Internet T-1) is a high-speed digitally transmitted connection to the Internet that transfers signals at 1.544 Mbps (1,544,000 bits per second) that can be divided into twenty-four 64 Kbps telephone lines or trunks.

Voice over IP is a digital phone service that allow users to make calls across the public switched telephone network (PSTN) via the Internet. By using a high speed Internet connection and a VoIP phone or analog telephone adapter (ATA), a user receives the same type of phone service as plain old telephone service (POTS) plus many additional features. For example, find me / follow me allow a user to enter all of the phone numbers the user wants to ring when the user's VoIP phone number is called. If you are at home, at the office, or on your mobile phone, all of your phones can be rung in succession or at the same time using VoIP!

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.

Multi-Site National and Global Network Solutions: As your organization grows, so does the importance of telecommunications integration and coordination. For example, we can design a Virtual Private Network (VPN) or Multi-Protocol Label Switching (MPLS) Network that can connect all of your locations to enable sensitive data to flow back and forth at a high speed without the risk of interception. Call us at (888) 255-5859.

MPLS works across various data protocols such as the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and frame relay. MPLS forwards most packets at layer 2 (switching) instead of at layer 3 (routing) level.

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.

POTS local loop speed is increased by up to 50 times when a DSL modem is attached at the customer premise and a Digital Subscriber Line Access Multiplexer (DSLAM) is connected to the local access loop at the local telephone company central office (CO).

On Telecom Links, you can learn how an Internet T1 works and why it is more reliable than DSL or cable.

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.
