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
