No, it's not:
"2.5 Gbps switch fabric (80 Gbps switching system
bandwidth) - This consists of the GSR16/80-CSC and the
GSR16/80-SFC fabric set. Each SFC or CSC card provides a
2.5 Gbps full-duplex connection to each line card in the
system. For a Cisco 12016 with 16 line cards, each with
2 x 2.5 Gbps capacity (full duplex), the system switching
bandwidth is 16 x 5 Gbps = 80 Gbps."
Note also that:
"On 120xx models, each 2.5 Gbps chassis slot has up
to four 1.25 Gbps serial line connections, one to each of
the switch fabric cards to provide a total capacity of 5 Gbps
per slot or 2.5 Gbps full duplex."
The upgraded fabric in the 124xx series is 10 Gbps
full-duplex, so you will not find any 12xxx model with 5
Gbps full-duplex to a slot.

They seem pretty clear to me, Chris.
