Huawei EFT4 Board is 4 channel FE Ethernet transparent transmission board
Huawei EFT4 Board Product Overview
Huawei EFT4 Board is an Ethernet transparent transmission board, which is mainly used to solve telecommunications applications such as Ethernet service access, bandwidth management, and Ethernet service convergence. It can realize the point-to-point transparent transmission of Ethernet services. इथरनेट बोर्डमा इन्टरफेस मार्फत, it realizes data transmission and reception, म्यापिङ, data flow control, and supports port-based point-to-point transparent transmission, data encapsulation/decapsulation, आंशिक ओभरहेड र सूचक प्रशोधन, भर्चुअल संयोजन, र SDH म्यापिङ / डिम्यापिङ, LCAS, आदि.
Huawei OSN1500 EFT4 board completes the encapsulation and mapping functions: in the upstream direction, the mapping module first encapsulates the Ethernet signal into LAPS, HDLC or GFP format and performs cascading. त्यसपछि, the mapping module converts the Ethernet signal into an SDH signal. In the downstream direction, the mapping module demaps the SDH signal and compensates for the virtual concatenation delay. Through the alignment operation, the mapping module decapsulates the data packet according to the encapsulation format. The data after decapsulation is sent to the network processing module.
