Mixing -TR and -SE line cards with RSP 880-SE

[IK4]

Hi everyone, 

I know that mixing -SE and -TR line cards is supported in ASR 9000 chassis.
Question is what is happening with operational mode of whole system when RSP880-SE is combined with mixture of -TR l -SE line cards, and in case of RSP880-TR and -SE line cards. Any recommendation or restriction for this combination of line cards ?

Thanks in advance.
