reachable network A network
that can be accessed (with
additional internet hops possibly
required) by a particular gateway.
remote connect device An
asynchronous device that is
indirectly connected to a DTC
through a modem and telephone
hook-up or through a PAD.
remote node Any network node
that is physically separate from
the node you are currently using
or referring to.
retransmission count (N2) The
maximum number of times a
frame will be retransmitted
following the expiration of the
Retransmission Timer, T1.
retransmission timer (T1) The
length of time that a transmitter
will wait for an acknowledgment
from a destination address before
attempting to retransmit a frame.
When choosing this value, factors
like the line speed and maximum
frame size should be taken into
account.
RFA Remote File Access. A
network service that allows users
to access file and devices on
remote nodes.
routing The path that packets or
fragments of a message take
through a network to reach a
destination node.
RMP Remote Maintenance
Protocol. HP proprietary protocol
used in DTC management.
RPM Remote Process
Management. A network service
that allows a process to
programmatically initiate and
terminate other processes
throughout a network from any
node on the network.
RS-232-C The Electronic
Industries Association (EIA)
Level 1 protocol specification that
defines electrical circuit functions
for 25 connector pins. HP
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 and can be
used for either modem or direct
connections.
RS-422 TheElectronicIndustries
Association (EIA) Level 1 protocol
specification implemented by HP
in a 5-pin version which can be
used for direct device connection
up to a distance of 1500 meters
(4000 feet).
S
security string An
alphanumeric character string
that functions as a password for
dial links. The security string is
used by the Dial IP protocol.
serial device Any device that is
attached to and communicates
with a computer by means of a
serial transmission interface.
