Chapter 2 31
Preparing to Configure DTCs
Defining the DTC
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:
DTC Event
Logging For each DTC, 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 and log a substantial
number of events. The log files could use a significant
amount of disk space.
Event logging classes do not apply for access to an
HP 3000 in an MPE/iX host-based management
environment using a DTC 16RX; any values entered in
these fields for the DTC 16RX will be ignored.
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).
