End-of-Sale and End-of-Life Announcement for the Cisco LC-OC12-DS3(=)

Cisco Systems® announces the end of life of the Cisco® LC-OC12-DS3(=). The last day to order the Cisco is December 30, 2004. Customers will continue to receive support from the Cisco Technical Assistance Center (TAC) until December 30, 2009. Table 1 describes the end-of-life milestones, definitions, and dates for the Cisco LC-OC12-DS3(=).

Customers are encouraged to migrate to the 4CHOC12/DS3-I-SCB(=), which is based on the ISE Architecture and offers all the features and functions provided by the LC-OC12-DS3(=), but at the same time provides all the enhanced benefits and functions of the ISE Architecture. The ISE-based linecards provide a superset of the functionality over the LC-OC12-DS3(=), which includes flexible channelization as well as dynamic provisioning. While LC-OC12-DS3(=) is channelized down to DS3, the ISE based line card—4CHOC12/DS3-I-SCB can be channelized to OC3 and/or DS3 and can be configured on a per port basis.
