Whakamaramatanga teitei 4 Channel Multiplexer - 8E1 + Whakaaturanga LCD + SNMP JHA-C2P-E8bF4R2 PDH Fiber Multiplexer - JHA

8E1+LCD Whakaatu +SNMP JHA-C2P-E8bF4R2

PDH Fiber Multiplexer

Tirohanga

Kei tenei taputapu te mana papatohu, e whakarato ana i te whakamarumaru 1 + 1 muka , tohu ki te tohu tohu whakaata, whakaaturanga LCD , i runga i te kaupapa o to maatau kamupene te whakawhanaketanga o te tuku whakaata PDH, whakamahia te VLSI motuhake me te SNMP NMS.

Ko te taputapu e whakarato ana i te atanga 1-8 * E1, 1-4 * 10 / 100M Ethernet atanga (Wire tere 100M) me te 2 atanga roha. Ko te atanga Itarangi 4Channel he atanga whakawhiti, ka taea te tautoko i te VLAN. 2 atanga roha ka taea te whakamahi hei teihana tuku o RS232/RS485/RS422 raraunga tukutahi. He tino ngawari. He mahi whakaoho. Ko te mahi he pono, he pumau, he iti te kaha o te kaha, te whakauru nui, te rahi iti
