Defining the DTC
The following parameters are required to define each DTC used for connection between
the HP 3000 and its asynchronous devices (terminals and printers). You can use the DTC
Configuration worksheets as shown later in this chapter to record the values selected for
each DTC.
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 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. 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.
A typical LAN address looks like: 08-00-09-1A-11-11.
If a valid LAN address is entered, then this DTC will be a managed
DTC on this system. If you want to define this DTC as a
non-managed DTC on this system, then use the value
00-00-00-00-00-00 as the LAN address. In this case you will only be
allowed to define NAILED devices for all the connector cards.
To configure a DTC 16RX for access to an HP 3000 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 is done
on the HP 9000 host using DTC 16RX Manager.
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.
If this DTC is a non-managed DTC then the DTC Node Name must
match the Node Name for the DTC on the system where this DTC is a
managed DTC being shared.
DTC IP Address (optional) The internet protocol (IP) address of the DTC. The IP
address is optional. It is used if your HP 3000 is configured as part of a
network and you want the DTC to be able to respond to PING/iX
requests.
