? CRC automatic alarm threshold can be set to isolate the poor quality transmission lines and cut off a single-direction. When 2M
branch circuit one direction error rate exceeds threshold, cutting off this direction the other direction is not affected; that is to say, both
of the Ethernetdirection transmission can be asymmetric
? Allow 8Channel E1 transmission time delay difference 100ms. When the margin exceed the allowed range, the system can automatically
stop on the E1 that time delay is too large to send data
