shared dial A dial link that
provides connection to more than
one remote system, although to
only one at a time.
shared-line access The feature
that allows two or more HP 3000
Series 900 hosts to use the same
DTC/X.25 Network Access card
on a DTC to access an X.25
network.
SIC Serial Interface Card. A card
installed in the front of the DTC
that acts as an interface between
a corresponding Connector Card
(CC) and the DTC’s processor.
slaved device A device that
shares the same DTC port as
another device and is connected,
to the other device, referred to as
its master, by a cable. The actions
of the slaved device are controlled
by the master device.
SNMP Simple Network
Management Protocol. An
industry standard for managing
networked computers in a
multi-vendor environment.
SNMP agent A network node,
such as a DTC, that is able to
respond to SNMP requests.
SNMP manager A network
management platform that is
running software which allows it
to manage SNMP nodes.
SNP Synchronous Network
Processor card; an alternative
name for an X.25 board.
