Cisco Systems® announces the end of life of the Cisco® 1-Port Channelized OC-12/STM-4 (OC-3/STM-1) Line Card. The last day to order the Cisco 1-Port Channelized OC-12/STM-4 line card 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 1-Port Channelized OC-12/STM-4 line card.

Customers are encouraged to migrate to the Cisco 12000 Series 4-Port Channelized OC-12/STM-4 (DS3/E3, OC-3c/STM-1c) POS/SDH ISE Line Card, which is based on the IP Services Engine (ISE) architecture and offers all the features and functions provided by the 1-Port Channelized OC-12/STM-4 line card, but also provides all the enhanced benefits and functions of the ISE architecture. Table 2 lists the part numbers for the end-of-life and replacement products.

The ISE-based line cards provide flexible channelization as well as dynamic provisioning. While the end-of-life line card is channelized down to OC-3, the replacement line card can be channelized to OC-3 and/or DS3 and can be configured on a per-port basis.
