Mô tả sản phẩm: Netlink OP-4E1*Eth*RS232 (NETWORK MULTIPLEXER)
product function：
Transfer 4 E1s,1 10/100M Ethernet and 1 RS232 signal through fiber .
product character:
(1) Provide 1 Ethernet interface (support VLAN, flow control, and self- negotiation; full/semi duplex, 10M/100M optional)
(2) Can provide at most 4 E1 channels transmission transparently, and 1 100M Ethernet data channel.
(3) Provide function of E1 remote loop, order Ethernet remote loop, fiber local loop, and 1 interface of phone(optional).
