PDH Fiber Multiplexer

Kakaretso

Sesebelisoa sena se na le taolo ea khokahano, se fana ka ts'ireletso ea 1 + 1 fiber back-up, ho supa phetiso ea optical, ponts'o ea LCD, motheong oa nts'etsopele ea k'hamphani ea rona ea phetisetso ea PDH optical, sebelisa VLSI e khethehileng le SNMP NMS.

Sesebelisoa se fana ka sebopeho sa 1-8 * E1, 1-4 * 10 / 100M Ethernet interface (Wire speed 100M) le 2 segokanyimmediamentsi sa sebolokigolo. 4Channel Ethernet segokanyimmediamentsi sa sebolokigolo ke switjha segokanyimmediamentsi sa sebolokigolo, ka tšehetsa VLAN. 2 segokanyimmediamentsi sa sebolokigolo e ka sebelisoa e le mocha oa phetiso ea RS232/RS485/RS422 asynchronous data. 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
