Configuring Systems for Terminals, Printers, and Other Serial Devices

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). 

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       The local station address of the DTC.The HP 2345B
Address               (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 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 on the HP 9000 host
                      using DTC 16RX Manageruses 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        The internet protocol (IP) address of the DTC. The
(optional)            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:

                                 Table 2-2.   
-------------------------------------------------
|                  |                            |
| 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:

                      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
                      Manageron 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     The number and types of connector cards in the DTC.
Boards)               (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, 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.

                      Event logging classes do not apply for DTC 16RX
                      access to an HP 3000 in an MPE/iX host-based
                      management environment; any values entered in these
                      fields for the DTC 16RX will be ignored.
