Attaching the Power System to a remote host system

This section shows four ways in which the Power System can be attached to a remote host system, which might be a System/370, System/390, or AS/400 system. These attachments enable Blueworx Voice Response to use SNA LU2 protocols to emulate a 3270 terminal and get access to the information on the host computer.

The four examples show how you can attach the Power System:

Using a token ring LAN and an IBM 3174 network gateway (Figure 1)
Using a token ring LAN and a network controller (Figure 2)
Using an SDLC attachment, modems, and a network controller (Figure 3)
Using a token ring LAN, an IBM 3174 network gateway that is attached via SDLC modems, and a network controller (Figure 4).

These are only examples. Depending on the distances involved, some of the items shown in figures Figure 1 through Figure 4 might be unnecessary.

Example A

Attach the Power System to a token-ring local area network (LAN) that is attached to the host through an IBM 3174 (used as a network gateway). This attachment requires the following items:

Token-ring adapter in the Power System
Cable to attach the Power System to the LAN
Token-ring adapter in the 3174

Example B

Attach the Power System to a token-ring LAN that is attached to the host via a network controller. This attachment requires the following items:

Token-ring adapter in the Power System
Cable to attach the Power System to the LAN
Token-ring adapter in the network controller

Figure 2. Data communications network attachment (example B)
This figure is described in the text which precedes it. Two machines are connected via a LAN to an IBM 3745 Communications Controller, which is in turn connected to the host system

Example C

Attach the Power System to the host using a single-drop SDLC attachment and modems. This attachment requires the following items:

Multiprotocol adapter in the Power System
Modems that operate at a rate compatible with the line speed

Example D

Attach the Power System to a token-ring LAN that is connected to the host through a network controller. The network controller is attached to an SDLC connection that is accessed via an IBM 3174 (used as a network gateway). This attachment requires the following items:

Token-ring adapter in the Power System
Cable to attach the Power System to the LAN
Token-ring adapter in the 3174
