T21E1
T21E1 is a SDH board card used in STN6200 platform to support E1 service convergence. It supports multiple clock selection, ensures clock frequency and phase synchronization of all nodes, and realizes correct and effective exchange of all data information. It adopts industry-leading chipset technology and fully supports international standards（ITU-T).

It adopts industry-leading chipset technology and fully supports international standards（ITU-T).
T21E1 can transmit 21 E1 services at the same time. The card supports E1 mapping to any multiplexing structure of 63 vc12 of STM1. With the line card, it can converge to OTU1 or OTU2 services, which can flexibly meet the simultaneous transmission of multiple services of customers. It is suitable for customer dedicated line access and multiple service convergence scenarios.
