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 (or T-1) T1 is a symmetrical local access connection to an Internet port that allows for downloads and uploads of up to 1.5 Mega Bits Per Second (Mbps) which is 30 times as fast as a 56 Kilo Bits Per Second (Kbps) dial-up connection over a standard Plain Old Telephone Service (POTS) phone line.
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.
Our clients include Fortune 500 Companies, Small-to-Medium Businesses (SMBs) Governmental Agencies, Defense Contractors, Hospitals, Law Offices, Internet Service Providers, Wireless ISPs, State Universities, Web Hosting Companies, etc.
Ethernet can be used to connect twisted copper pair networks and to connect fiber optic cable networks.
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.
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.
High-speed Microwave, 3G, and Satellite Wireless Internet service connects subscribers who are in remote locations or unique locations where DSL or other types of Internet access is unavailable. All you need to connect to wireless Internet is an unobstructed view of the provider Internet transmitter - receiver or satellite.

Layer 2 MPLS VPNs (L2VPNs) are similar to Frame Relay, Asynchronous Transfer Mode, or point-to-point Wide Area Networks (WANs).
