Integrated Services Digital Network (ISDN)
Note: ISDN Not
Yet Available
Though your system can provide ISDN capabilities, they are not
yet agency approved and available for your system. Currently,
a plug has been placed in the ISDN port pending approval of
ISDN licenses. Once agency approval of ISDN for the DEC 3000
Model 600/600S/700 AXP system has been granted, you will be
contacted by your Digital sales representative to inform you of
the ISDN certification. At that point, you must remove the plug
from the ISDN port before connecting to the ISDN network.
The following information explains the ISDN capabilities for
your system pending license approval.
Australian ISDN
Connections
The ISDN interface in this equipment has not completed
Australian ISDN network connection certification testing and
as such does not have an AUSTEL permit for connection. In
Australia it is an offence to connect non-permitted devices to a
public telecommunications network and may attract a fine of up
to $12,000.
Plug in ISDN
Connector
Your system is shipped with a foam plug inserted in the ISDN
connector so that the port is inaccessible. Before using the port
when ISDN is available, remove the foam plug carefully so that
you do not damage any of the port connections.
ISDN
Capabilities
ISDN is a digital telecommunications network, providing
connectivity for voice and data applications.
Your workstation includes an ISDN Basic Rate S/T interface,
which includes:
• two 64-kilobits-per-second B channels
• one 16-kilobits-per-second D channel
Use of ISDN B
Channels
The B channels can be used for digitized voice, circuit-switched
data transmission at up to 64 kilobits per second, or for
packet-switched data transmission.
