4E1 + 4FE PDH Fiber Multiplexer JHA-CPE4F4

Nchịkọta

Ngwaọrụ a na-enye 1-4*E1 interface, 1-4*10M/100M Ethernet interface (Wire Speed ​​100M) na 2 mgbasawanye interface. 4 * Ethernet interface bụ mgba ọkụ interface, nwere ike ịkwado VLAN. Enwere ike iji interface mgbasawanye 2 dị ka ọwa nnyefe nke RS232/RS485/RS422 data asynchronous. Ọ na-agbanwe nke ukwuu. O nwere ọrụ mkpu. Ọrụ ahụ bụ nke a pụrụ ịdabere na ya, kwụsie ike, na ike dị ala, ntinye dị elu, obere nha.
