Description |
This parameter specifies the format of the data frame to be transmitted. The E1 links are classified into DOUBLE_FRAME and CRC4_MULTI_FRAME. Where, DOUBLE_FRAME stands for a double-frame structure and CRC4_MULTI_FRAME stands for a multiframe structure. Generally, CRC4_MULTI_FRAME is used. This type of link has an error code check function to greatly reduce the error rate of the frame synchronization detection. The T1 links are classified into EXTENDED_SUPER_FRAME and SUPER_FRAME. Where, SUPER_FRAME stands for the superframe and EXTENDED_SUPER_FRAME stands for the extended superframe. Generally, EXTENDED_SUPER_FRAME is used. This type of link has an error code check function. |
