Kakaretso

Sesebelisoa sena ke sesebelisoa sa ho fetisetsa optical point-to-point se entsoeng motheong oa VLSI. Sesebelisoa se fana ka sebopeho sa 1-8 * E1, 1-4 * 10/100 / 1000M Ethernet interface (Wire Speed ​​1000M) le 2 ea ho atolosa. 4 * Ethernet interface ke switch interface, e ka tšehetsa VLAN. 1 segokanyimmediamentsi sa sebolokigolo ka sebelisoa e le mocha phetiso ya RS232/RS485/RS422 asynchronous data, omileng letshwao la ho ikopanya, 1Channel ditsitithale fono ya kgwebo ka ba boikhethelo. E tenyetseha haholo. E na le ts'ebetso ea alamo. Mosebetsi o ka tšeptjoa, o tsitsitse, 'me o sebelisa matla a fokolang, ho kopanya ho phahameng, boholo bo fokolang.
