Used Cisco Carrier Routing Systems

The CRS-1 (different from a GSR or a 7600), is built around a midplane. Each "line card" (Modular Services Card) has a part that goes into the back and a part that goes in the front, called Physical Layer Interface Module (PLIM). The MSCs are all the same and work with any kind of PLIM which are available for different kinds of transmission media.
