This topic provides switch connection troubleshooting
information.
Caution! If you verify the switch administration
settings and check the cabling and still cannot connect properly
with the switch, contact the remote support center. Do not perform
the following procedures unless instructed to do so by the remote
support center. These procedures are primarily for systems outside
of the U.S. and Canada.
No call answer
If you do not have call answer, check the cable connections and
the hunt group on the switch.
Failure to detect far-end disconnect
In some cases, there might be issues detecting the
far-end disconnect in some countries. Additional administration
might be required on the switch to ensure that the far-end disconnect
is recognized.
By default, most switches use U.S. parameter settings for different
switch tones in all countries. Therefore, all dial tone, busy tone
detection, and reorder tones are based on U.S. settings. These tones
do not create problems in the internal call answer function. Problems
arise in countries where the disconnect (usually busy) tone is provided
by the network.
Note: This problem does not occur if the public switch
network gives a polarity disconnect or wink disconnect. Order the
polarity disconnect or wink disconnect option from the central office,
if possible.
If you experience this problem, use tone
administration to capture and tune the tones.
