2x2 or 2x1

	The Call Type ﬁeld determines which type of HSCSD call the HP/
	Agilent 8922 establishes the next time a call is initiated.
	If you select 2x1, the HP/Agilent 8922 tries to establish a call with 2
	downlinks and 1 uplink when a call is next initiated. The measure
	timeslot ﬁeld will no longer be visible, nor will the controls concerned
	with the second uplink (Slave TX level, Slave input level, Slave
	input level control mode).
	If you select 2x2, the HP/Agilent 8922 sets up a call with 2 downlinks
	and 2 uplinks. The Measure timeslot ﬁeld appears, along with controls
	associated with the second uplink. The Measure timeslot ﬁeld is set to
	the default for each unit (slave for slave, master for master).
	Each of these changes is subject to the conditions that a call must not be
NOTE
	in progress when the change to this ﬁeld is made and that the ﬁeld will
	not change if changing the slave timeslot would make it take on an
	illegal value.
