The following figure identifies some of the hardware devices that are part of the POS SPA architecture. The figure shows the four ports that are supported by the 4-Port OC-3c/STM-1 POS SPA only.

Figure 1. 4-Port OC-3c/STM-1 POS SPA Architecture

Every incoming and outgoing packet on the 4-Port OC-3c/STM-1 POS SPA goes through the SONET/SDH framer and field-programmable gate array (FPGA) devices.

The following figure identifies the primary hardware devices that are part of the 2-Port OC-48c/STM-16 POS SPA architecture.

Figure 2. 2-Port OC-48c/STM-16 POS SPA Architecture

The following figure identifies the primary hardware devices that are part of the POS SPA architecture. The figure shows a single optics transceiver. The 1-Port OC-192c/STM-64 POS/RPR XFP SPA supports XFP optics.

Figure 3. 1-Port OC-192c/STM-64 POS/RPR XFP SPA Architecture

In POS mode, every incoming and outgoing packet on the OC-192 POS SPAs goes through the SONET/SDH framer and SPI4.2 interface.

The following example shows an output of the show interfaces pos command on Cisco ASR 1000 Series Aggregation Services Routers with a 1-Port OC-192c/STM-64 POS/RPR XFP SPA installed in slot 1:
