PDH Fiber Multiplexer

Nchịkọta

Ngwaọrụ a nwere njikwa njikwa, na-enye 1 + 1 fiber back-up nchebe, na-atụ aka na-arụtụ anya nnyefe, LCD ngosi , na isi nke ụlọ ọrụ anyị mmepe nke PDH ngwa anya nnyefe, na-eji pụrụ iche VLSI na SNMP NMS.

Ngwaọrụ na-enye 1-8 * E1 interface, 1-4 * 10 / 100M Ethernet interface (Wire speed 100M) na 2 mgbasawanye interface. 4Channel 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
