The DTC Routable Communications Server
A DTC Routable Communications Server controls the transfer of data between the
devices connected to it and the computer systems which those devices can access.
The DTC controls communications that would otherwise need to be controlled by
the computer system. Therefore, the DTC frees system resources and can improve
the processing performance of the Hewlett-Packard computers that use the DTC as
their communications controller.
Only the DTC 16RX can be managed by the DTC 16RX Manager. Refer to the DTC
hardware installation manual (part number: J2064-90001) for a more detailed
description of the DTC.
The DTC consists logically of two boards: a LAN (or processor) board, and a
connector board with 16 asynchronous ports. You cannot add boards to the DTC.
Extended switching configurations (back-to-back)
The DTC must be connected to the LAN. It can also be connected directly to
systems other than HP 3000 Series 900 or systems running Internet Services. This is
called extended switching, or back-to-back switching.
Port groups
On the DTC the ports are grouped into two port groups. Each port group has eight
ports and can be attached to a modem or direct-connect connection accessory. A
port group corresponds to a connector on a DTC.
LAN board
A DTC has a LAN board that handles the overall management of the DTC. The
LAN board is the central processing unit (CPU) of the DTC and contains the
firmware responsible for much of the data communications processing. It also
provides the DTC with its connection point to the LAN via an Attachment Unit
Interface (AUI) cable and a Medium Attachment Unit (MAU) for ThickLAN
connection, or a BNC T-Connector for ThinLAN connection.
