Glossary
Node Manger HP OpenView Network Node Manger provides fault, configuration, and
performance management for multivendor TCP/IP networks.
P
port An outlet through which a device can be connected to a computer, consisting of a
physical connection point and controlling hardware, controlling software, and
configurable port characteristics. Ports can be thought of as data paths through which
a device communicates with the computer.
port group A port group corresponds to a connector on the rear panel of the DTC 16RX. The
type of port group you configure depends on whether you attach a modem or direct
connect connection accessory.
printer name A character string of up to 16 characters specified in the DTC 16RX Manager
configuration to define a printer by name. A printer name can be shared by several
printers (port pool).
probe proxy server A node on an IEEE 802.3 network that possesses a network directory. A probe proxy
server can provide a node with information about other nodes on the same or other
networks of an internetwork.
program captive device
See programmatic device.
programmatic access Access to devices by software running on a system. The HP DTC Device File Access
product, for example, allows HP-UX hosts to programmatically access devices
connected to a DTC 16RX.
programmatic device A device operating under control of a program running on a computer. Programmatic
devices can be used for input, output, or both, depending on the device and how it is
opened by the controlling program.
PSN Packet Switching Network. The main characteristic of a packet switched network is
that the data it handles are broken down into packets for transmission over the
network. Each data packet is able to pass through the network by a different path
without loss of data. On arrival, the packets are reassembled into the original data
stream. An X.25 network is a PSN.
R
remote node Any network node that is physically separate from the node you are currently using
or referring to.
Routable AFCP A method of encapsulating AFCP in UDP packets to permit communication between
DTC ports and an HP 3000 Series 900 system across a routed IP network. A front-
end DTC is required.
RS-232-C The Electronic Industries Association (EIA) Level 1 specification that defines
electrical circuit functions for 25 connector pins. Hewlett-Packard provides two
implementations of this standard: a 3-pin version for direct connections up to a
distance of 15 meters (50 feet), and a version which makes use of additional circuits
