Composite Link Speed and Clocking Commands

DSU Clock	The DSU Clock command allows the internal DSU to accept				timing from it's internal
timing oscillator ($DSUACLI) or from the		$DSUCL		DDS Network'sReceive Bipolar Signal. The $DSUACLI
	command enables the internal DSU on link A to establish the				timing. DDS
Clocking command $DSUCLD is used whenever				the internal DSU is connected to DDS network line. The
	$DSUCLD command is the factory default and automatically				configures the
MultiMux clocking.
DSU Speed	The DSU Speed command sets the speed of the internal DSU.				The $DSUASP56000
command sets the internal DSU on link A		$DSUSP		to a link speed of 56K bps. The default DSU speed is 56K
bps.	The DSU speed commands are as follows:
					$ D S U A /
BSP2400	$DSU/BSP4800
	$DSUA/BSP9600		$DSUA/BSP19200
	$DSUA/BSP56000
Mux Clock	The Mux Clock command enables the MultiMux to accept timing				from either it's internal
timing oscillator ($MUXCLI) or derive $MUXCL			timing from a synchronous full-duplex external device
($MUXCLE). The $MUXBCL command is used any time an				external link device is connected to the link or a
synchronous	device is connected to Port B as a Sync Data Channel. The				$ MUXACLI
command configures link A for internal clocking. If				the Sync Data Channel is configured, the $MUXBCLI
command	sets the MultiMux up for internal clocking. If the clocking is being				provided by
the synchronous device, the $MUXBCLE command				would be used to set the clocking. The default condition for
the	MultiMux is internal clocking.
Mux Speed	The Mux Speed command selects the clocking speed when				clocking is provided by
the MultiMux. The only time the mux		$MUXSP speed needs to be set is when the MultiMux is providing the
clocking. The Mux Speed commands are used when the ports				are set as composite link:
$MUXA/BSP 2400		$MUXA/BSP 4800		$MUXA/BSP 7200	$MUXA/BSP 9600
$MUXA/BSP 14400			$MUXA/BSP 19200
$MUXA/BSP 38400		$MUXA/BSP 57600		$MUXA/BSP 64000	$MUXA/BSP 76800
$MUXA/BSP115200		$MUXA/BSP 128000		$MUXA/BSP 256000
