No connection.
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 communication is not
acceptable under the current LAN
environment (when using LAN).
Consult with the system administrator
so that the packet for Communication
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
the communication with another
party.
Answering the call is not permitted
by the remote terminal as it is
operating for setups, etc.
Ask the remote party to permit
answering a call.
The remote terminal is not set to
auto answer mode.
Ask the remote party to set the
terminal to auto answer mode, or to
answer a call manually.
The ISDN telephone numbers are
not set up in the remote terminal
(when using bonding).
Ask the remote party to set up “Area
Code” and “Local Number” in the
ISDN Setup menu correctly (page
85).
The eighth digit and up of the ISDN
telephone numbers are not the same
when connecting using bonding
(when the remote party uses the
communication system of an older
model such as the PCS-1600).
Connect without using bonding, or
use the ISDN telephone numbers that
are the same in the eighth digit and
up.
There is some problem with the
remote terminal.
Try to dial the number of another
terminal.
A message appears on the screen.
See “On-Screen Messages” (page
255).
