Chapter 2 Overview: Cisco 12000 Series Router Shared Port Adapters
2-Port, 4-Port, and 8-Port OC-3c/STM-1 and OC-12c/STM-4 POS SPA, 4-Port OC-3c/STM-1 POS SPA, and 8-Port
Note Three different faceplates exist for either the 2-Port, 4-Port, and 8-Port OC-3c/STM-1 and
OC-12c/STM-4 POS SPAs. They each contain the same LEDs and the number of ports are 2, 4 and 8
respectively.

The 2-Port, 4-Port, and 8-Port OC-3c/STM-1 and OC-12c/STM-4 POS SPA and the 4-Port and 8-Port
OC-3c/STM-1 POS SPA LEDs are described in Table 2-31.
2-Port, 4-Port, and 8-Port OC-3c/STM-1 and OC-12c/STM-4 POS SPA and 4-Port
and 8-Port OC-3c/STM-1 POS SPA Interface Specifications
The framer processes incoming and outgoing SONET or SDH frames. The framer operates at OC-3 line
rates (155.52 Mbps) and OC-12 line rates (622.08 Mbps). Packet data is transported with a
user-configured encapsulation (such as Point-to-Point Protocol [PPP]) and is mapped into the layer 2
frame.
The 2-Port, 4-Port, and 8-Port OC-3c/STM-1 and OC-12c/STM-4 POS SPA and the 4-Port and 8-Port
OC-3c/STM-1 POS SPA interface complies with the following IETF RFCs:
1 C/A (Carrier/Alarm) LED 3 STATUS LED
