TNN1ETMC Is Huawei OptiX OSN7500 Packet Interface Boards
Huawei OptiX OSN7500 Packet Interface Boards TNN1ETMC 03020XRC Overview
TNN1ETMC (8xFE+4xFE/GE electrical interface board).
The ETMC is available in one functional version, namely, TNN1.
As a packet interface board, the ETMC works with the EG8 to process four GE services or 12 FE services.
ETMC boards provide four FE/GE auto-sensing electrical ports and eight FE electrical ports to receive Ethernet services, and work with the EG8 to process the received Ethernet services.
The ETMC consists of the interface converting module, service processing module, management module, clock module, and power module.
