Kakaretso

Sesebelisoa se sebelisang theknoloji ea reverse direction multiplexing ho bokella lipotoloho tse ngata tsa E1 ho fetisetsa data ea Ethernet ea 4Channel 100BASE-TX. E ka hlokomela phetoho lipakeng tsa 1 ~ 8 channel E1 le Ethernet optical interface, ho etsa hore likanale tsa E1 li hokahane le Ethernet optical interface. U sebelisa encapsulation ea GFP, tšehetsa LCAS (sekema sa tokiso ea bokhoni ba khokahano) le protocol ea LAPS.

Sesebelisoa sena se ka tšehetsa tlhophiso ea mocha oa 1-8 Channel E1, se khona ho lemoha palo ea E1 ka bo eona ebe se khetha E1 e teng. E lumella nako ea phetiso ea mela ea E1, 1channel/4channel/8channel Ethernet bandwidth is1984Kbit/s, 7936Kbit/s, 15872 Kbit/s.
Sesebelisoa se fana ka ts'ebetso ea alamo. Mosebetsi o ka tšeptjoa ebile o sebelisa matla a fokolang, ho kopanya ho phahameng, boholo bo nyane. Ts'ehetso ea Tsamaiso ea Marang-rang , Mosebetsi o ka sehloohong oa tsamaiso ea marang-rang ke ho phethahatsa lipatlisiso bakeng sa lisebelisoa tsa lehae le tse hōle le tsamaiso ea tlhophiso ho kenyelletsa le ho botsa boemo ba alamo moleng oa E1, boemo ba ho sebetsa ba Ethernet, le taolo ea loopback joalo-joalo.
