Cisco (PA-POS-2OC3)
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.
