That's V2R5, as you noted below. The new Communications Server component was
introduced in V2R4, but only for Unix applications. IIRC, the CS included VTAM
and TCP/IP and they were pretty tightly integrated.
The announcement of 2.4 and preview of 2.5 is here:

CS OS/390 adds a new, completely redesigned,TCP/IP stack, which exploits
native OS/390 services and multiprocessing capability, for significantly
improved performance, reliability, availability, serviceability, and
scalability.
