Description

Cisco IOS® Software Release 12.0DC was released to introduce the Node Route Processor (NRP) on the Cisco 6400 Series Serial Universal Access Concentrator platforms. The NRP is an ATM switching blade based on the Cisco 7200 series router that resides in the Cisco 6400. There can be one or more of both node switch processors (NSPs) (Digital Signal Processor) and NRPs in a Cisco 6400 platform at any one time. This custom hardware design offers Digital Subscriber Loop (xDSL) technology features. The Cisco IOS Software Release 12.0(3)DC adds new functionality such as PPP over Ethernet (PPPoE) and Service Selection Gateway (a feature set sometimes referred to as NRP-SSG). This is the first time web-based service selection has been introduced into a branch of Cisco IOS.
