Description

Cisco IOS® Software Release 12.0DB was released to introduce node switch processors (NSPs) on the Cisco 6400 Series Serial Universal Access Concentrator platforms. The NSP is an ATM switching blade based on the LightStream 1010 that resides in the Cisco 6400. There can be one or more of both NSPs and node route processors (NRPs) in a Cisco 6400 at any one time. This custom hardware design offers Digital Subscriber Loop (xDSL) technology features.

In December 1998, Cisco IOS Software Release 12.0(1)DB was introduced as the first version of the Cisco IOS 12.0DB release train. Cisco IOS Software Release 12.0DB is directly synchronized to Cisco IOS 12.0. In the future it will reparent and start synchronizing to Cisco IOS Software Release 12.0T. This will occur around the time frame of Cisco IOS Software Release 12.0(4)T. For more information, see the following pages:
