To display the parameter configuration of the BITS clock sources, enter the dspclkparms command as
Step 3
shown in the following example:
M8850_LA.8.PXM.a > dspclkparms
BITS Cable
BITS Signal Type :
The above example shows the default BITS clock configuration parameters. The cable type can be either
twisted pair or coax. The signal type can be either data mode or sync mode.
Step 4 If you need to change the BITS clock configuration parameters, enter the cnfclkparms command as
follows:
M8850_LA.8.PXM.a > cnfclkparms <signal type> <cable type>
Replace the signal type variable with 1 to select data or with 2 to select sync. Replace the cable type
variable with 1 to select twisted pair cabling or with 2 to select coaxial cabling.
Step 5 To configure an additional BITS clock source, repeat
additional source. The clock parameters configured in Steps 3 and 4 apply to both BITS clock inputs.
Step 6 To display the clock source configuration, enter the dspclksrcs command.
The dspclksrcs command is described in the
Chapter 9, "Switch Operating

Descriptions
Replace <priority> with the type of clock source that is
either primary or secondary. The default is primary.
The <shelf> value is always 1 and is optional.
For the BITS clock, the <slot> number is 7 for a
Cisco MGX 8850 (PXM1E/PXM45) or
Cisco MGX 8950 switch, or slot 1 for a
Cisco MGX 8830 switch.
The <port> number identifies the line on the
PXM1E-UI-S3 or PXM1E-UI-S3/B back card to which
the BITS clock is connected, and the type of line
connected. Select the appropriate port number from the
following:
• Port 35 = upper line
• Port 36 = lower line
The -bits option specifies whether the clock source line
is an E1 or T1.
The -revertive option enables or disables the revertive
feature for all clock sources.
Note In releases prior to Release 5, this option applied
only to BITS clock sources.
