LINE SHARE 120H
4.2 Standard Operations
When a call comes in, all the phones begin to ring (including extension
phones, phones connected to the PHONE and TAD ports). The Line Share
120H allows 6 rings to the telephones before it automatically transfers the call
to the FAX/MODEM port. If you or your answering machine answer the call
before this transfer occurs, the Line Share 120H listens for the following
signals:
• a CNG tone
• an access code for the FAX/MODEM port # 9 9
If the Line Share 120H detects any of these signals, it routes the call to the
FAX/MODEM port.
If an unanswered call is transferred to the FAX/MODEM port, the
Automatic Ring Reduction feature engages.
For calls that occur after this, the Line Share 120H will route calls to the
FAX/MODEM port after 3 rings.
The Automatic Ring Reduction Reset will reset the ring count to 6 rings
after 5 minutes of inactivity on the FAX/MODEM port. You can also manually
reset the Line Share 120H to 6 rings by performing any of the following steps:
• Lift the receiver of any phone device on the line connected to the Line
Share 120H and hang it up.
• Answer a call from any phone before the call is routed to the
FAX/MODEM port.
• Place an outbound call from any phone connected on the line connected
to the Line Share 120H.
