Q: What should be noted in the link binding of NE40 E1/CE1?
A: NE40/80 support MP through hardware; namely, the functions are realized by interface board. At present, only cpos, 8CE1 and 8CT1 support MP.
8CE1 and 8CT1 support it through DSP; the hardware of 8E1 has no DSP, so it does not support MP.
Additionally, NE40/80 do not have virtual template, so they cannot realize binding through virtual-template.
Therefore, the binding of 2M link of NE40/80 can only be realized through MP-GROUP, and only 8CE1 and 8CT1 interface board can realize binding.
