Introduction
Typical Network Configurations
Back-to-Back Access
By arranging DTCs and DTC terminal connections in a special way,
terminal users can establish communications with an MPE V computer.
This is referred to as back-to-back access.
Figure 1-6 shows two DTCs in a simple back-to-back configuration.
DTC 1 has terminals connected to it. DTC 2 is connected through one of
its ports to the Advanced Terminal Processor (ATP) card in the MPE V
computer. A terminal user connected through DTC 1 is able to establish
a communications link to the MPE V system by going through DTC 2.
Note that the OpenView Windows Workstation is on the same LAN as
the DTCs involved in the back-to-back configuration.
