MDW 9040 Wireless Pocket Phone Installation and Use,
503-801-19016 Issue 2, February 2001
Synchronization When two or more radio modules are connected, one radio module shall be deemed
the “Control” radio module since it is administered to control the synchronization for
all of the other radio modules to which it is connected; that is, when the “Control”
radio module is transmitting or receiving signals (Control LED is Steady Green), the
expansion or other radio modules connected to it transmit or receive signals at the
same time (Expansion LEDs are Steady Amber).
Note: Radio modules can be installed in a single zone or dual zone
configuration with up to the same number of handsets
that is, 9 radio
modules (18 handsets) per zone for key systems such as PARTNER or
MERLIN or MERLIN MAGIX and up to 15 radio modules (30 handsets)
for PBX systems such as MERLIN LEGEND or MERLIN MAGIX (in
PBX mode) and DEFINITY.
The following is a diagram showing three radio module units operating in a single
zone configuration providing six handsets with the appropriate switch interface.
