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