Chapter 1 Cisco CRS Carrier Routing System
Chassis Components
–SIP is a carrier card that is similar to a PLIM and inserts into a line card chassis slot and interconnects to an MSC, FP, or LSP like a PLIM. Unlike PLIMs, SIPs provide no network connectivity on their own.
–SPA is a modular type of port adapter that inserts into a subslot of a compatible SIP carrier card to provide network connectivity and increased interface port density. A SIP can hold one or more SPAs, depending on the SIP type and the SPA size. POS/SDH and Gigabit Ethernet SPAs are available.
•A chassis midplane that connects MSCs, FPs, or LSPs to their PLIMs and to switch fabric cards. The LCC supports 40G, 140G, and 200G fabric cards, as follows:

•The Cisco
A mixture of 40G, 140G, and 200G fabric cards is not supported except during migration.
