1. Cisco CRS-1 SIP-800
   The processing on the Cisco CRS-1 SIP-800 is performed by two PLIM ASICs, each of which can process up to 20 Gbps of traffic. SPA subslots 0, 1, and 3 are associated with one PLIM ASIC, while SPA subslots 2, 4, and 5 are associated with the second PLIM ASIC. See the figure below for subslot locations.
