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).

In a T1, each of the twenty-four 64 Kbps channels can connect to the Internet individually or the Internet T1 can be configured to aggregate all of the 24 channels into one large 1.544 Mbps concatenated channel.

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.

Internet access via Ethernet is becoming more and more popular to meet the growing demand for dynamic high bandwidth increases. For example, an increase from 10 to 100 Mbps can be accomplished by a High Speed Internet over Ethernet provider by simple changing the settings on already installed Ethernet switches. This scalability is cost effective for customers in that bandwidth can be increased or decreased quickly and easily, on demand, without the necessity of adding or changing datacom equipment as would be required with T1 / T3 or E1 / E3 local access lines.

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 facilitate layer 3 IP VPNs, layer 2 VPNs, Quality of Service (QoS), Class of Service (CoS) and to guarantee Service Level Agreements.
