Descripción del producto

PCM**0 multiplexer: The PCM**0 equipment multiplexes ****0 channels of voice data into ***6 E1 data. As an equipment which has import quality and based on SEL Company in Pairs. With stable working characteristic the PCM**0 is able to be used in *0KV electric power substations and **0V electric power substations. Each interface has many protection circuits. Stainless steel with Alloy oxidation Aluminum board make the sub-frame not change color. Two power channels to constitute 1*1 protection. 4 channels can be plugged in central multiplex unit, each central multiplex unit has 4 E1 ports, so there are totally ***6 E1 ports, *2 channels remaining for inserting various service cards. To use *0 channels each unit, 6U sub-frame has **0 channels which equivalent 4 PCM equipments. *6 E1 ports have the ability of cross-connect **2X**2 time slots flexibly, With the help of network management software, the PCM equipment could select routing port automatically. *6 E1 routing-proposals can be defined in accordance with the E1 quantity for auto routing switch. In fact, *2 channels for the service card can be plugged in multiplex unit, So if necessary, the equipment could upgrade to *4 E1 and work as a completely cross-connect equipment. This equipment can work as *6 PCM that is the other way to explain the cross-connect. Like other PCM made by our company, PCM**0 has various of service interfaces, including ***0HZ carrier magnets interfaces that is used in military, stereo signal interfaces in broadcasting radio and so on. The most application of the interfaces is S and O interfaces of the telephone, 2/4 wire interface and various interfaces for data.
