End-of-Sales for TTM 4OC-12

The first production versions of the 4OC-12 POS line card known as TTM 4OC-12 are not orderable after December 1, 1999.


Customers that have purchased TTM 4OC-12 POS line cards will have one year from the end-of-sale announcement to upgrade, for free, to Performance-based (Perf) 4OC-12 line cards. An active program will be in place for the year-long period, where customers will have the option to automatically receive free upgrades. The upgrades will only be authorized if a TTM 4OC-12 POS sales order can be referred to.

After October 2000, upgrades to Perf 4OC-12 POS need to use the standard Technology Migration Plan (TMP) credit program.

Calculations for credits or trade-in values can be found by using the TMP calculator found at:

End-of-Contract Renewals

Service contracts on these products will not be renewed after 12/01/2002.


The TTM line cards will be supported by Cisco TAC through 2002, but no changes to the functionality of the line card or enhancements can be made under any conditions. If issues with the TTM 4OC-12 card arise and additional capabilities are necessary or there are issues with existing functionality, then the card needs to be upgraded to the Perf 4OC-12 POS line card.
