5. Troubleshooting/Helpful Hints
• Why are fax calls being routed to my telephone and/or answering machine?
• The Line Share 120H is a semi-automatic line sharing device, therefore
calls are routed first to the TAD and PHONE ports. When a device
connected to one of these ports answers a call, the Line Share 120H then
listens for fax tones to transfer the call. If you answer a call and hear a fax
tone, keep the phone off-hook until your fax answers and then hang up.
• Why can’t I receive faxes when I’m away from the Line Share 120H?
• Check the following settings and procedures:
1. Leave a message on your answering machine for callers to press #99 to
send a fax, and leave 4 seconds of silence before your message.
2. Set your fax to answer on 1 ring.
3. Set your answering machine to answer on 2 rings.
• Why don’t fax calls transfer to the fax when I answer the phone?
• Some fax machines do not produce fax tones, therefore, when you receive
this type of call, press #99 on your tone phone, wait for the fax to answer
and then hang up.
• Why don’t fax calls transfer to the fax when my answering machine answers a call?
• You may not have the 4-second silence at the beginning of your answering
machine announcement message. If you do, contact Technical Support
for more information.
• The LED doesn’t light on the Line Share 120H. What should I do?
• Check your power connection. If power is connected properly, make sure
that you are using a 12-volt AC power adapter.
• I don’t have dial tone with the phone(s) connected to the Line Share 120H. What
should I do?
• Check all of the phone-line connections and repair or replace any
damaged cables.
