A telephone system is common in a medium or large office arrangement in
which calls are coming in on 2 or more lines and can be routed to any
number of extensions. The system typically has features like call holding,
music on hold, conference calling, and intercom paging.
Figure 3-6 shows telephone devices connected to the Line Share 120H for a
telephone system; follow the same procedures if you have a mini-telephone
system in your home or small office. For the Line Share 120H to operate
properly, it must be “in front” of the telephone system. In other words, it must
connect directly to the incoming telephone line. Connect the other
equipment as previously shown.
All equipment on that line (telephone system, fax, computer modem,
and so on) must connect directly to the Line Share 120H.
CAUTION
You should be familiar with telephone wiring to complete this
installation. If you have any questions or are not confident that you can
complete this installation procedure, call for technical support.
Do not plug the Line Share 120H into a telephone system phone jack.
You may damage your phone system.
NOTE
If your phone number is a direct dial number within your company’s
telephone system and it accessible from external and internal locations
without assistance, you might be able to connect the Line Share 120H
directly to your extension. Plug the LINE-IN line cord into your extension
(wall) jack. With this configuration, the Line Share 120H must be “in
front” of all equipment.
However, your telephone system must send out analog signals to all
extensions. Make sure your telephone system is compatible with this
application or damage to the system may occur.
