H901EDSH is a 32-channel TDM E1 upstream board, supporting transparent transmission and convergence of digital data network (DDN) private line services
Used for PSTN reconstructing, accessing DDN private line, data and voice services without maintaining the DDN separately. This simplifies the network architecture
2*16-channel E1 interfaces (NE96 Connector, 96PIN, PCB PressFit Type)
