Overview

The IDM-MUX90 is a multi-service SDH access device with SDH technology at its core and STM-1 level performance, fully compliant with ITU-T standards. This device provides users with access to multiple services and SDH optical transmission, offering two 155.52Mbps optical interfaces (A and B), four 10M/100M Ethernet interfaces, multiple groups of E1 interfaces, and 64K services. It features ITU-T G.813 standard network element timing, VC-12 cross-connection, and channel protection functions. In addition, the IDM-MUX90 is used to construct point-to-point, point-to-multipoint chain and ring transmission networks. The IDM-MUX90 multi-service access platform can be widely applied in telecommunications data services, power, banking, public security, military and other sectors for public telephone network access or dedicated line information transmission.
