ETV 30 ports FXS/FXO Voice over E1 PCM Multiplexer
♦Product Introduction
ETV-PCM30 integrated service access equipment is used to transmit 30 64K voices on E1 transmission channel or optical fiber transmission channel, or part of the time slot is used to transmit N*64K data service (Ethernet data), or part of the time slot is used for RS232 Multiplexing transmission equipment for data services.
ANV-PCM30 adopts a stand-alone structure and multiplexes 10/100Base-T Ethernet, voice channels, RS232, etc. in an E1 transmission, which is suitable for extending the working distance of the interface through channels such as optical fiber, microwave, and DDN private network.
When ANV-PCM30 works in optical transmission mode, the Ethernet interface can reach a line speed of 100M.
