Port Adapter Overview
The PA-POS-2OC3 provides two Packet-over-SONET (POS) ports in a single port adapter slot. The two
ports function as either dual independent OC-3c/STM1 ports or a single port with automatic protection
switching (APS). The PA-POS-2OC3 is used as a direct connection between the supported router or
switch platform and external networks.
The PA-POS-2OC3 fits into a single port
adapter
slot on the Cisco 7204VXR router, Cisco 7206VXR
router, Cisco 7201 router, Cisco 7301 router, Cisco 7304 PCI port adapter carrier card in a Cisco 7304
router, Cisco 7401ASR router, Cisco 7500 series routers (Cisco 7505, Cisco 7507, Cisco 7513), and the
Cisco 7600 series routers with FlexWAN or Enhanced FlexWAN.
Note
The Cisco 7206VXR router can be used as a router shelf in a Cisco AS5800 universal access server.
