We need to connect the SDH Equipment "Optical boards" to the BSC Equipment "Optical Boards", and I got the parametters for the BSC Equipment "GOIUA Board" in M2000 are same with that in the SDH in T2000 such as the J0 and J1 and J2.
But in BSC for J2 I got additional parametters "Tx frame format" and "RX frame format" that have two options "Double-frame" or "CRC4-Multiframe".
So for the SDH optcal board is need to set this parameters or no need?
And if no need, so what is the characters of the J2 in SDH Optical Boards to set the BSC in M2000?
The OSN and BSC have same setting for J0,J1 and J2 and they can configure same in OSN or BSC (usually is Huawei SBS)
For Frame Format type: have no relation with transmission.
To choose Double Frame or CRC4_Multiframe both ends (BSC and MSC) should be same, And it's always for Huawei by default is "Double Frame"...
