PA-POS-1OC3 Overview

The PA-POS-1OC3 provides a single Packet-over-SONET (POS) port in a single port adapter slot. The port functions as a single independent OC-3c/STM1 port. The PA-POS-1OC3 is used as a direct connection between the supported router or switch platform and an external network.

The PA-POS-1OC3 fits into a single port adapter slot on the Cisco 7201 router, Cisco 7204VXR router, Cisco 7206VXR router, Cisco 7301 router, Cisco 7304 PCI port adapter carrier card in Cisco 7304 router, the 7401ASR router, Cisco 7500 series routers (Cisco 7505, Cisco 7507, Cisco 7513), and Cisco 7600 series routers (Cisco 7603, Cisco 7606, Cisco 7609, Cisco 7613) with FlexWAN or Enhanced FlexWAN.

Note The Cisco 7206VXR router can be used as a router shelf in a Cisco AS5800 universal access server. Refer to the Cisco AS5800 documentation at the following URL: http://www.cisco.com/en/US/products/hw/univgate/ps509/tsd_products_support_series_home.html

PA-POS-1OC3, PA-POS-2OC3 specifications

Cisco Systems has long been at the forefront of networking technology, providing solutions that empower organizations to enhance their connectivity and communication capabilities. Among its impressive lineup, the PA-POS-2OC3 and PA-POS-1OC3 modules stand out as significant components designed to optimize performance in service provider and enterprise environments.

The PA-POS-2OC3 and PA-POS-1OC3 modules are designed for use with the Cisco 7600 Series routers and are tailored for Packet Over SONET (POS) transport. Supporting the OC-3 speed of 155.52 Mbps, these modules provide reliable high-speed connectivity, enabling organizations to efficiently manage data traffic and ensure rapid data transfer across their networks. The PA-POS-2OC3 offers dual OC-3 capabilities, allowing for higher aggregate bandwidth and redundancy options, making it common in demanding network environments.

One of the main features of the PA-POS-2OC3 and PA-POS-1OC3 is their enhanced support for advanced networking protocols, including MPLS (Multiprotocol Label Switching). MPLS facilitates efficient data routing and improves bandwidth utilization by enabling multiple types of traffic to be consolidated over a single network. This is crucial for organizations looking to deploy services like VoIP, video conferencing, and other bandwidth-intensive applications.

The modules also offer robust error correction and monitoring capabilities, which are essential for maintaining service quality in mission-critical applications. Administrators can monitor performance and diagnose issues in real-time, enabling swift responses to potential concerns that could disrupt service.

Moreover, the PA-POS-2OC3 and PA-POS-1OC3 are designed with features that support enterprise-grade security and scalability. This is particularly beneficial for organizations expecting growth or requiring enhanced protection for sensitive data as it traverses the network.

In summary, Cisco's PA-POS-2OC3 and PA-POS-1OC3 modules represent essential building blocks for high-speed networking solutions. Their support for OC-3 connectivity, advanced routing protocols, and robust monitoring capabilities make them ideal for both service providers and enterprises. Through increased scalability, improved bandwidth management, and enhanced security, these modules allow organizations to adapt to the ever-evolving landscape of data communications effectively. With Cisco at the helm, businesses can trust in a networking solution that not only meets current demands but is also primed for future growth.
