The 3745 and 3746 Communicaitons Controllers End of Service has been announced in some parts of the world.
3745 and 3746 Communication Controllers and NCP Software
IBM has previously stated that it has no plans to end service for the 3745 and 3746 Communications Controllers before 2010. In line with this statement, IBM announced end of service for these products in Japan and countries in Europe, Middle East and Africa (EMEA) as of December 31, 2010. Service for these products will continue in the Americas and Asia Pacific until further notice. IBM recommends customers who use the 3745 and 3746 Communication Controllers in these geographies develop migration plans consistent with IBM’s strategic direction, which is to migrate to the Communication Controller for Linux.
NCP support: IBM intends to support and maintain ACF/NCP and associated software products (EP, NPSI, NTuneMon) beyond the 3745 and 3746 product support dates and reminds its customers that monthly license fees for these software products remain in effect.
All statements regarding IBM's future direction or intent are subject to change or withdrawal without notice, and represent goals and objectives only. When IBM announces end of service for these products, all existing 3745 and 3746 service contracts will be honored.
If you continue to require SNA solutions that require Network Control Program (NCP) functions, you can consider IBM Communication Controller for Linux on System z (CCL) as a migration strategy to replace your IBM Communications Controllers (374x).
The Gigabit Ethernet and 1000BASE-T OSA-Express2 and OSA-Express3 features have the capability to provide channel connectivity from System z operating systems to CCL when using the Open Systems Adapter for the Network Control Program (OSA for NCP) supporting the Channel Data Link Control (CDLC) protocol.

Features: OSA-Express2 (#3364, #3365, #3366) and OSA-Express3 (#3362, #3363, #3367, #3369, #3373) Gigabit Ethernet and 1000BASE-T
CHPID type: OSN
OSA for NCP operating system support:
