Permet de transmette 4 ports Ethernet 10/100Base-T sur 1 Port E1 (120 Ohms/75Omhs) non tramé.
It converts Ethernet frame structure to E1 frame structure, and recovers E1 frame structure to Ethernet frame structure at the other side, which enables Ethernet data to transmit in telecom network based on E1.
Because it is efficiently and effectively used the spared bandwidth of telecom providers, it saves the networking cost and improve the efficiency and can be used immediately.
The outstanding feature is supporting 4 Ethernet interfaces with VLAN function
Support Ethernet data transmitting transparently or according to timeslots in E1 line; bandwidth ranges from 64Kbps-2048Kbps.
Support 4 auto-negotiate and full/half duplex Ethernet interfaces, Support MDI/MDI-X auto-sensed, support intercommunicate and VLAN division between 4 Ethernet interfaces, support VLAN transparent transmission.
Support network management function, able to supervise the working status.
Support data filter at local side.
Synchronously provide 75Ω unbalance /120Ω balance E1 port.
