PVC Permanent Virtual Circuit.
A permanent logical association
between two physically separate
DTEs that does not require call
set-up or clearing procedures.
PXP See Packet Exchange
Protocol.
Q
Q bit Qualified bit. When set in
DATA packets the Q bit signifies
that the packet’s user data is a
control signal for the remote
device, not a message for its user.
QuickVal A software program
that tests whether Network
Services are operating correctly
between nodes.
R
RDBA Remote Data Base Access.
A network service that allows
users to access data bases on
remote nodes.
remote node A node on an
internetwork other than 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)
Length of time the transmitter
will wait for an acknowledgment
from the destination address
