Overview
4/8E1 PDH Multiplexer can multiplex 4E1 or 8E1 and 2-ports Ethernet (10/100Mbps line speed) signals in one fiber channel to transmit. It is suitable for low capacity, point-to-point application of remote transmission. The circuit part of the equipment is fully digitized. The whole equipment is reliable, stable, easy to install and maintain. It has good temperature and voltage characteristics, complete alarm functions, one RS232 asynchronous interface and remote loop back functions(from software). At the same time, it can be managed from management software Fi-View-MP through its Console port or through chassis FC-912.
