Chapter 1. General Information on 3745 and 3746 Controllers
This chapter will give you general information on the 3745/46 family of controllers.
The IBM 3745 and 3746 Controllers Family
For nearly three decades, IBM's advanced line of communication controllers (3705,
3720, 3725, 3745, and 3746) have proved an effective solution for rapid changes in
network technology. In particular, the 3745s and, more recently, the 3746-900 and
the 3746-950, have proved cost effective for network evolution and adaptability to
new functions.
IBM controllers include the following:
These controllers were originally designed for the attributes and advantages of
SNA. Later innovations in the same model line incorporated developments in
APPN, HPR, and IP networking technologies:
The 3746 Models 900 and 950 form the latest generation of controllers, the 3746
Nways Multiprotocol Controllers. These controllers are the basis of efficient and
reliable multiprotocol networks that support both SNA and TCP/IP applications.
By integrating the 3746-900 and the 3746-950 into your network, you can add the
advantages of APPN/HPR and IP, while providing support for existing SNA
configurations.
Figure 1-1 on page 1-2 illustrates the development of 3745 and 3746 controllers, in
line with the evolution of networking technologies.

The 3746-950 can operate simultaneously as an IP router and APPN/HPR
Network Node (NN), independently of any 3745 running NCP.
The 3746-900 can operate simultaneously as an IP router, APPN/HPR NN, and
an NCP-controlled SNA subarea node or APPN composite network node
(CNN).
