Description
：
When the E1/T1 interface is connected
，
Both parties must be identical on the E1/T1 interface parameters.
，
Because both E1/T1 cannot have signal loss/frame out-of-synchronization/multiframe
out-of-synchronization/slip code conditions
，
Because the inconsistency of individual characteristic
parameters will cause data channel failure / error code / slip code / out of step, etc.
。
These characteristic
parameters are: impedance / frame / line coding / CRC check,The above parameters need to be negotiated
with the peer when docking.
