An MPLS T1 is a virtual private network (VPN) for securely connecting two or more locations over the public Internet or a private MPLS network. MPLS T1 lines are secured through encryption on a customers router, which is known as a CPE based MPLS VPN, or on the MPLS providers network router, which is known as a network-based MPLS VPN. MPLS T1 services are typically provisioned over Internet T1 lines or a private MPLS line, higher bandwidth speeds are offered as well (MPLS Ethernet, NxT1, DS3), with options for managed MPLS T1 services. An MPLS connection provides class of service (CoS) by utilizing MPLS VPN technology to prioritize and route time-sensitive data based on application. MPLS lines are used by businesses to provide reliable, secure, MPLS VPN service for applications including credit card processing, file sharing, data backup, MPLS VOIP, or remote access. MPLS lines can also be configured by most MPLS service providers to carry voice, Internet, and IP VPN services together as an Integrated MPLS T1 line. MPLS T1 service is also known as an MPLS VPN, MPLS WAN, MPLS Circuit, MPLS Network, or VPN T1.
