4-4 Issue 2 November 1996
Call disconnects
immediately after an
attempt to connect;
BUSY or NO
CARRIER may be
displayed on the
local terminal
device; green LED
turns off, red LED is
on.
The far-end device
is busy with
another call.
Try the call again.
The telephone
number was dialed
incorrectly.
Check the number of the far-end
device that you wish to call and try the
call again.
The far-end device
is not busy, but the
PBX has restricted
access to the
called device.
This situation can only be resolved by
having the PBX readministered to
remove the access restriction.
The value in
S-register
S7 does
not allow enough
time for the call to
be completed.
Increase the value of S-register
S7.
