COM 1 or COM2 is connected to the DCD product
The user port can be any unused port, including the Ethernet port
Messages can pass from a user to the DCD product and from the DCD product
to a user through the TimeSource 3100
The TID (SID for DCD) is used to identify commands that go to the DCD product.
The TimeSource 3100 passes any TID not its own through to the DCD product.
In the reverse direction, all commands received from the DCD product are
passed through to the user.
DCD is fully managed except for firmware download.

Alarm Programmability
New releases of TimeSource (1.05.03 and higher) allows the user to provision the
alarm escalation parameters that were hardcoded in the previous releases of
TS3100.hex. The defaults for this release remain the same as were previously
hardcoded. This feature can be used to set the programmability for such alarms as
GPS, HOLDOVER, SPAN-X, and RO-X.
The TS3100 alarms can be programmed for GPS and HOLDOVER types of events.
The SPAN-X alarms can be programmed for AIS, ERROR, and LOS types of
events. The RO-X alarms can be programmed for ERROR and LOS types of
events.
Note: The TID of the TL1 command must be the SID of MIS.
