Troubleshooting
No connection. Some of the system settings are not
correct. Set the system settings correctly
referring to “Registering Local
Information” (page 46).
The IP address and network mask
are not set correctly (when using
LAN). Ask the system administrator to set
them correctly (page 62).
The LAN or ISDN cable is
disconnected. Connect correctly (pages 25, 26).
The LAN or ISDN cable is
connected to the incorrect
connector. Connect correctly (pages 25, 26).
The LAN or ISDN cable is down. Replace the cable with a new one.
The cable exclusively designed for
the ISDN connection is used for

LAN). Use the cable for LAN connection.
Incorrect type of cable (cross or
straight cable) is used for the LAN
or ISDN connection. Use the correct type of cable.
The DSU is turned off. Turn on the DSU.
If you disconnect the
communication with an abnormal
procedure, e.g., unplugging an
ISDN cable or turning off the
system during communication, you
may not connect to the ISDN line
for a while (when using ISDN). Turn off the power of the system and
wait for a few minutes before turning
it on again.
If you repeat plugging/unplugging
or turning on/off, you may not
connect to the network for a while
(when using LAN). Turn off the power of the system and
wait for a few minutes before turning
it on again.
LAN connection timeout (when
using LAN). Try again later.
Packet for videoconferencing is not
acceptable under the current LAN
environment (when using LAN). Consult with the system administrator
so that the packet for
videoconferencing becomes
acceptable under your LAN
environment.
The remote terminal is not turned
on. Ask the remote party to turn on the
terminal.
It takes a long time for the remote
party to be able to answer from the
standby mode. Ask the remote party to cancel the
standby mode.
The remote party is in
communication with another party. Call the remote party after they end
