Preparing to Configure DTCs

Defining the DTC

Chapter 2

Defining the DTC

The following parameters are required to define each DTC used for connection between

the HP e3000 and its asynchronous devices (terminals and printers).

DTC Name A name for the DTC, up to eight alphanumeric characters, beginning

with a letter. Each DTC configured on the system must have a unique

name.

DTC LAN Station Address The local station address of the DTC. The HP 2345B (DTC

48) station address is printed inside the front cover. The HP 2340A

(DTC 16) station address is printed on the label located on the upper

right-hand corner of the back panel of the DTC. The HP J2070A (DTC

72MX) and J2062A/J2063A/J2064A (DTC 16iX/16MX/16RX) station

address is printed on the label located at the lower center of the back

panel of the DTC.

A typical LAN address looks like: 08-00-09-1A-11-11.

For DTC 16RX access to an HP e3000 in an MPE/iX host-based

management environment, use the value 00-00-00-00-00-00 as the

DTC 16RX LAN address. Configuration of the DTC 16RX on the HP

9000 host using DTC 16RX Manager uses the DTC’s IP address and

not its LAN address.

DTC Node Name A fully qualified node name of the DTC, in the form

nodename.domain.organization, where each field can contain 16 or

fewer characters (alphanumeric, underscores, or hyphens). The first

character of each field must be alphabetic.

Assign meaningful node names. For example, ACCTS.IXNET.ACCTG and

PAY.IXNET.ACCTG are meaningful names for two nodes on the same

Local Area Network (LAN) within the accounting department. One

node (ACCTS.IXNET.ACCTG) is used by the accounts staff. The other

node (PAY.IXNET.ACCTG) is used by the payables staff. The domain

field is the same because the nodes belong to the same network. The

organization field is the same because the nodes belong to the same

internetwork.

DTC IP Address (optional) The internet protocol (IP) address of the DTC. The IP

address is optional. It is used if your HP e3000 is configured as part of

a network and you want the DTC to be able to respond to PING/iX

requests.

An IP address has four fields of decimal numbers:

xxx.xxx.xxx.xxx

where xxx is a number from 0 to 255.

An IP address has two parts: a network portion and a node portion.

The following are examples of three types of IP addresses:

Class A: nnn xxx.xxx.xxx

Class B: nnn.nnn xxx.xxx

Class C: nnn.nnn.nnn xxx
