AUXILIARY LINE	The auxiliary jack (the top jack) on each line module bridges and monitors the
TELEPHONE	outside line connected to the first line jack (the second jack from the top, line
	A) on the module. If you have a second line module, its auxiliary jack
	connects to line E, and you can gain access to it with a basic Touch-Tone or
	rotary dial telephone. Note the location of the Aux jack in Figure 22.
	This jack provides many services.
	● You can connect accessories, such as a modem, answering machine, or a
	Fax machine to it and reap the benefits of a dedicated line.
	● When the line is not used by any accessory attached to the Aux jack,
	MERLIN Plus system voice terminal users have access to it.
	● The jack can be used as a single-line extension phone that not only works
	as part of the MERLIN Plus communications system, but also continues to
	work after a power failure.
	NOTE: A MERLIN Plus system voice terminal is not designed for and
	will not work in the Aux port.
