The NIC-5EB Ethernet bridge is used to transfer data from 1 to 5 E1 channels to one Ethernet channel for fast transmission,

The NIC-8EB Ethernet bridge is used to transfer data from 1 to 8 E1 channels to one Ethernet channel for fast transmission,

As an extension device of Ethernet, it can utilize the abundant E1 channel resources of existing operators to achieve interconnection between two Ethernet networks at a lower cost.

characteristic

Low cost Ethernet access and interconnection based on TDM

application

Used for operators with E1 resources (China Mobile, China Unicom, China Telecom, Tietong) and private network customers (railway, power, public security)

function characteristics

NIC-5EB transmits Ethernet data through 5 E1 circuits

NIC-8EB transmits Ethernet data through 8 E1 circuits

⊙ Can display remote alarms and support remote reset function

⊙ A 16ms transmission delay difference is allowed between any two E1 channels

⊙ Real time detection of available E1 circuits and automatic allocation of line bandwidth

⊙ Intelligent monitoring of E1 circuit quality, automatically shutting down E1 circuits with errors

⊙ Manually set the E1 error threshold to 10-4, 10-5, 10-6

⊙ Support one-way closure of faulty E1 circuits to achieve asymmetric transmission

⊙ Supports automatic sorting of MAC frames

⊙ Support the transmission of VLAN Trunk frames

⊙ Support flow control function based on 802.3x, support SNMP network management

Networking application

Option 1: On up to 5 E1 circuits provided by the operator, NIC-5EB utilizes reverse multiplexing technology to provide Ethernet interconnection services between two users across regions, with a maximum bandwidth of 9.92Mbps. As shown in the following figure:

Option 2: In the FTTX solution, NIC-5EB utilizes its unique built-in optical Ethernet interface function to save users one optical transceiver for access while achieving comprehensive end-to-end network management. As shown in the following figure:
