5700MSC-IP
IP Network Grand Master Clock & Video Master Clock System
Page - 78 Revision 0.2
5.3.2.5. Setting the Time Reference Lock Type
INPUT
The Lock Type menu item is used to control how and when the 5700MSC-
IP
updates its system time to match the time reference. This decision is
made whenever the system time is in disagreement with the time reference.
Select User when user intervention is required before updating system time.
When the 5700MSC-IP
system time does not match the time reference a
warning will be displayed on the front panel (TIME JAM NEEDED), which
can optionally trigger an SNMP trap. The user must initiate a manual jam of
reference time into system time using the Jam Time menu item in order to
get system time to match the time reference.
Select Never
to ignore the time reference completely unless the user
performs a manual jam. No warnings are generated in this mode.
When set to Always the system time of the 5700MSC-IP will constantly track
the time reference. Any change in the time reference will be immediately
applied to the system time of the 5700MSC-IP.
If Daily is selected, the 5700MSC-IP system c
lock will run independently
from the time reference and jam once daily at the time of day specified by
the Input Jam Time control.

If the time reference has been set to SNTP, the time lock type is forced to Daily, no
matter what this control has been set to.
5.3.2.6. Setting the Daily Jam Time for the Time Reference
INPUT
When the Lock Type is set to Daily, the 5700MSC-IP system time will run
independently from the time reference and jam to it once a day. This menu
item is ignored if the Lock Type is set to anything other than Daily.
If the time reference is set to SNTP then this sets the time to do a daily
SNTP synchronization, and the Lock Type is not applicable.
Enter the time of day in 24-hour format that the 5700MSC-IP should perform
this daily jam
. When the jam occurs, the update will ripple to all output
timecode clocks. The NTP server and IRIG outputs will also be affected.
The time specified should be during a period when it will have a minimum
effect on system operation.

5.3.3. Configuring the Jam Input
These menu items allow the user to initiate an immediate forced synchronization of the master system
oscillator to its frequency reference, or the system time to its time reference.
CAUTION: These controls perform an immediate action once the SELECT button is pressed. The
text “Live control” will be shown on the left LCD with a red background as a warning.
