host-based network
management Method of
managing asynchronous
communications for HP 3000
Series 900 computers. All of the
controlsoftwareis configured on a
single host and is downloaded to
the DTCs that are managed by
that host. With host-based
management, there is a
permanent relationship between
each DTC and the host, and
terminal users can access only
the single system that owns the
DTC their terminal is connected
to.
host-based X.25 The
management of X.25 network
connections from a host computer.
Host-based X.25 network
connections are made through a
DTC Network Access card
installed in a DTC managed by
the host. All configuration is
accomplished using the NMMGR
utility. It is not necessary for a PC
to be part of the LAN when you
are using host-based X.25.
host computer The primary or
controlling computer on a
network. The computer on which
the network control software
resides. For HP purposes, it may
also be used to distinguish the
HP 3000 Series 900 system (host)
from the DTC.
HP ARPA Telnet Express A
DTC dedicated to providing
protocol conversion between
Telnet on TCP/IP and AFCP to
allow incoming calls from the
ARPA environment to HP 3000
systems.
HP block mode Block mode
transmission method employed
by HP computers where the
system controls the block mode
handshake. When HP block mode
is used, the user program need
not concern itself with data
transfer protocol.
HP PPN Hewlett-Packard
Private Packet Network.
Hewlett-Packard’s own
packet-switching X.25 network,
which gives users full control over
the administration and security
of their data communications.
HP TS8 A terminal server that
can support up to eight
asynchronous serial connections.
When used in back-to-back
configuration, users can access
HP 3000 MPE/V systems on it via
a DTC.
idle device timeout Timeout
defined by the Configure: CPU
command. When the timer lapses,
a device connected to the DTC
user interface that is still inactive
will be disconnected.
IEEE 802.3 A standard for a
broadcast local area network
published by the Institute for
Electrical and Electronics
Engineers (IEEE). This standard
is used for both the ThinLAN and
ThickLAN implementations of
the LAN.
