Overview Of SPA-8XOC3-POS
The Cisco SPA-8XOC3-POS is a Shared Port Adapter (SPA) developed exclusively for the ASR 9000 Series routers. It provides eight ports for OC-3/STM-1 POS (Packet over SONET/SDH), significantly increasing network connectivity and transmission capabilities. OC-3/STM-1 denotes Optical Carrier level 3 or Synchronous Transport Module level 1 in the SONET/SDH network hierarchy, respectively. POS stands for Packet over SONET/SDH, which refers to a communications protocol for transmitting packets as the Point-to-Point Protocol (PPP) over SONET/SDH. The key feature of the SPA-8XOC3-POS is its scalability. This modular SPA allows for network growth by simply adding more port adapters. It is hot-swappable, so capacity expansion can be performed without causing system interruptions. The Cisco SPA-8XOC3-POS is important in ASR 9000 series routers, offering vital support for networks using OC-3/STM-1 POS. This flexible and scalable adapter supports quick and simple adjustments to changing network needs, making it a highly valued asset in dynamic and growth-oriented networking environments.
