IMUX-500 (COT)
BR Optical MUX is a device which accepts up to DS1, DS1E, DS3-class private lines and multiplexes them with dependent signals at the subscriber’s device (RT) and sends them optically (with OC1 signal), and conducts demultiplexing and line distribution at a device (COT) at a branch office. This device can be divided into COT which can be used in relation to toll centers and RT. COT mostly is used at central offices of network providers which should provide services to multiple subscribers and RT can be conveniently used by premises of customers who want to receive the service.
