[c-nsp] SPA-POS-1xOC48 on SXF or SRA on 7600?

[Phil Bedard]

	Looking at the datasheet for the 1-port OC48 POS it says that the  
minimum release on the 7600 for that SPA is 12.2(33)SRA but in the  
hardware configuration docs for the SIP-400 it give some caveats for  
the OC48 SPA when running 12.2(18)SXF... The SIP-400 is supported in  
SXE...  I'm a bit confused by the docs on when support first showed  
up for that SPA...
