[c-nsp] SIP-400 and 10GbE SPA

[MKS]

Hi There

According to cisco SIP-400 can
"Ability to run 4 GE line rate for 64-byte packets, and OC-48 line
rate for 48-byte packets for POS, HDLC, etc. with select services"
https://www.cisco.com/en/US/prod/collateral/routers/ps368/product_data_sheet0900aecd8027c9e6.html

Can someone please clarify what exactly this means.

Also if I put a 10GbE SPA into a SIP-400 what is the expected
performance of that?

Thanks
