Rear (MSC) View of Line Card Chassis
The Cisco ASR 14000 series 8-slot line card chassis contains:
•
As many as eight
modular services cards (MSCs, also called line cards) and eight
physical layer
interface modules (PLIMs). The MSC and PLIM are an associated pair of cards that mate through
the chassis midplane. The MSC provides the forwarding engine for Layer 3 routing of user data, and
the PLIM provides the physical interface and connectors for the user data.
The MSC can be associated with several different PLIMs, which provide different interface speeds
and technologies. The available PLIMs are:
–
1-port OC-768c/STM-256c packet-over-SONET (POS); available in short-reach (SR) optics.
–
4-port OC-192c/STM-64c POS/DPT; available in long-reach (LR), intermediate-reach (IR),
short-reach (SR), and very-short-reach (VSR) options.
–
OC-48c/STM-16c POS/DPT, configurable with 1 to 16 ports; available in long-reach (LR) and
short-reach (SR) options. This PLIM supports pluggable optics.
–
10-Gigabit Ethernet (GE); available in long-reach (LR) optics.
This PLIM supports pluggable
optics, and can be configured with 1 to 8 ports.
