Chapter 4. ESCON C Figure 4-1. ESCON Attached Controllers Overview ESCON controllers, including the PCI ESCON Adapter (PBSA), can be connected to the mainframe in more than one fashion. As shown in Figure 4-1, Controller 1 is attached directly to one of the mainframe’s ESCON channels. Assuming the mainframe is running a single Logical Partition (LPAR), this is simplest option for connecting an ESCON controller to the mainframe. - Page 22 Finally, using both ESCON Directors and EMIF, it is possible for a single ESCON controller to communicate with multiple Logical Partitions (LPARs) running on multiple mainframes, using multiple ESCON channels. Because an ESCON controller may be attached to an ESCON director, which may be connected to multiple mainframes and Logical Partitions (LPARs), it is necessary to configure the ESCON controller in order to define how the unit will appear to each environment.
- Page 23 Channel Link – The address of the ESCON director port that connects to the mainframe this device is to communicate with. The value range is from 01-FE hexadecimal. In Figure 4-2 the mainframe uses a channel link address '02' to communicate with Server 1.

Page 29: Tcp/Ip Direct Connect 23
Chapter 5. TCP/IP D TCP/IP Direct Connect software included with the PCI ESCON Adapter provides high-performance, point-to-point TCP/IP communications between a Windows server (Windows 2000 or Windows NT 4.0) and the mainframe. TCP/IP Direct Connect operates over Channel-to-Channel (CTC) or Multi-Path Channel Plus (MPC+) links. TCP/IP Direct Connect is not required and does not need to be installed for TCP/IP Passthrough for Windows NT, Communications Server, Microsoft’s Host Integration Server or Microsoft’s SNA Server. -
Page 30: Windows 2000
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. - Page 31 2. Click OK when Setup displays it’s Welcome dialog (Figure 5-4). Figure 5-4. TCP/IP Direct Connect Install Confirmation 3. The TCP/IP Direct Connect Properties dialog will display (Figure 5-5).

Page 47: Tcp/Ip Routing
TCP/IP Routing TCP/IP Direct Connect is a Network Driver Interface Specification (NDIS) compliant adapter driver. TCP/IP Direct Connect makes the PCI ESCON Adapter appear exactly like any other Network Interface Card (NIC) to the Windows server. As a result when TCP/IP Direct Connect and a PCI ESCON Adapter are installed along with one or more Local Area Network (LAN) adapters the Windows server becomes a multihomed system. - Page 48 Subnet 0 Subnet 1 Subnet 2 Subnet 3 As shown, the Ethernet segment makes up subnet 0 and the Token-Ring makes up subnet 1. Subnets 2 and 3 are currently not used. The router’s Ethernet port is assigned an IP address in Subnet 0 and the Token-Ring port is assigned an address in subnet 1.
- Page 49 Figure 5-26. TCP/IP Direct Connect Configuration Screens Notice also that the subnet these two addresses are in is different than the subnet of the server’s LAN adapter (207.168.12.68). Microsoft’s TCP/IP stack can be configured to automatically forward IP packets between network adapters as long as those adapters are in different subnets.
