24 PCI ESCON Adapter Installation Guide
TCP/IP Direct Connect supports three link types across the ESCON channel:
Channel-to-Channel (CTC), High-Speed Access Services (HSAS) for UDP, or Multi-
Path Channel Point-to-Point (MPCPTP). HSAS and MPCPTP require installation of
MPC+ for Windows (MPC+).
CTC links use two ESCON devices (one for read, one for write) to communicate with
mainframe TCP/IP stacks such as OS/390 TCP/IP, MVS TCP/IP and VM TCP/IP.
These links support simple TCP/IP applications such as Telnet, TN3270, and FTP.
High-Speed Access Services is a MPC+ link specifically designed to work with the
OpenEdition TCP/IP stack provided with OS/390 version 2 release 4 and above.
HSAS provides support for applications using Universal Datagram Protocol (UDP).
The System/390 SAP R/3 implementation uses HSAS TCP/IP to retrieve data from
DB/2 running under OS/390.
MPCPTP links provide full TCP/IP communications over MPC to OS/390 version 2
release 5 and above. Applications such as Telnet, TN3270, FTP, and Web Servers
would use a MPCPTP link to communicate with OS/390 TCP/IP over MPC+.
Windows 2000
Installation
TCP/IP Direct Connect provides a setup program for installing itself into a Windows
2000 environment. The setup program may be run as many times as necessary to
provide connection to each TCP/IP stack running on the mainframe.
Step
1. Insert the TCP/IP Direct Connect for Windows 2000 floppy into your systems
drive and invoke the setup program (see Figure 5-3).
