Even if your telephone system switch is Caller ID capable, it will not pass analog Caller ID.
Therefore, the POS series units must be connected to the phone lines coming into the building from the
telephone company. These lines are branched (split or half-tapped) and connected to the input jacks of
the monitoring unit. If these lines are not modular, solid wire to modular adapters must to be installed
