Preparing to Configure DTCs
Defining the DTC

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.
Att: Network Information Center
7990 Boeing St.
Vienna, VA 22183
[phone] or FAX [phone]
For DTC 16RX access to an HP e3000 in an MPE/iX host-based
management environment, the IP address of the DTC16RX 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.
DTC 16iX/16MX/16RX has its two port connectors built directly onto
its backplane for support of up to 16 asynchronous devices. It does not
have removable cards; you do not specify the number or type of cards
for a DTC 16iX/16MX/16RX.
The valid card types are:
For DTC 16 and DTC 48:
D for direct connect cards (up to 8 ports per card),
M for modem connect cards (up to 6 ports per card),
X for DTC/X.25 Network Access cards (for connection)
For DTC 72 MX:
L for the LAN card, pre-installed in slot 0
A for asynchronous processor boards (up to 24 ports per
card for direct and modem connections)
X for DTC/X.25 Network Access cards (for X.25
connection).
DTC Event Logging For each DTC, you may specify which event logging class is to be
enabled. Event logging class 1 logs catastrophic events and will always
be enabled. Class 2 logs critical events; class 3 logs non-critical events;
classes 4 and 5 log informative events and class 6 provides statistical
information. It is recommended that you only enable classes 4 through
6 when you encounter problems, because they will generate a
substantial amount of events logged.
