Before Configuring Terminal and Printer Connections
Defining the DTC
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.
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
where nnn represents the network portion and xxx
represents the node portion of the address. The network
portion must be the same for all nodes on the network;
the node portion must be unique for all nodes on the
network. Examples of IP addresses for two DTCs on the
same network follow:
C 192.191.191 008
C 192.191.191 009.
You can obtain a Class B or Class C IP address from:
Government Systems, Inc.
Attn: Network Information Center
7990 Boeing Ct.
Vienna, VA 22183
[phone] or FAX [phone]
For DTC 16RX access to an HP 3000 in an MPE/iX
host-based management environment, the IP address
of the DTC 16RX is configured using the DTC 16RX
Manager on the HP 9000 host and not on the HP 3000.
Any value entered for the DTC 16RX in NMMGR will
be ignored.
DTC Cards (or
DTC Boards) The number and types of connector cards in the DTC.
(The cards are also referred to as boards.) DTC 16 can
have up to 2 asynchronous cards and 1 DTC/X.25
Network Access card, DTC 48 up to 6 cards, and
DTC 72MX up to 4 cards.
