4.4.2 MMU II Master vs. Slave Configuration

This configuration will allow two MMU IIs to be used connected to one transceiver.
The function here, since the RS485 has not yet been implemented, would be to allow
two MMU IIs to connect and carry on a phone conversation as in a party line
situation. The Slave will not be able to indicate signal strength as that is a function
of the RS232 control line and not implemented as part of this feature... yet.
Full operation of the MMU II in a master slave relationship will require
implementation of the RS485 control bus. This is not yet released and when it is all
slaves will function as the master does in an installation.
To configure two MMU IIs to communicate over POTS line with one transceiver,
follow the below procedure.
Perform the following configuration and testing with reference to the MMU II
Operators Guide, and the Pilot's Guide for description of function and use of the
knobs and menus.
