Data leased line is a data transmission service that uses optical fiber, digital microwave, and open circuits, and uses a digital transmission channel to transmit digital signals. It can provide point-to-point and point-to-multipoint transparent transmission of data leased circuits for users to transmit data, images, Information such as voice provides circuit transmission services with a variety of rates from 2Mbps to 2.5Gbps, and is generally used in intra-enterprise intranet networking.

Line classification:

Data lines can be divided into local data lines, long-distance lines, and international long-distance lines according to geographical areas.

According to the line type, there are DDN, Frame Relay (FR), ATM, SDH, MSTP, Ethernet dedicated line, MPLS-VPN, etc.

  • MSTP

    "MSTP dedicated line" service refers to the use of multi-service transmission node (MSTP) technology, relying on the transmission network, with 2Mbps as the granularity, providing customers with flexible bandwidth adjustment and Ethernet access functions, the access rate is between 2Mbps and 1000Mbps Data line business.
