Stratum	Code	Meaning
-------	----	-------
0	DCN	DCN routing protocol
0	NIST	NIST public modem
0	TSP	TSP time protocol
0	DTS	Digital Time Service
1	ATOM	Atomic clock (calibrated)
1	VLF	VLF radio (OMEGA, etc.)
1	callsign	Generic radio
1	LORC	LORAN-C radionavigation
1	GOES	GOES UHF environment satellite
1	GPS	GPS UHF satellite positioning
1	ACTS	ACTS telephone modem dial-up
1	IRIG	Inter-Range Instrumentation Group signal

Note, for TrueTime time servers only GPS, ACTS and IRIG are presently used. Further, a primary time server's outgoing NTP packet will have its reference identifier field set to ntpSysRefClockIdent."

ntpControlInput OBJECT-TYPE

SYNTAX DisplayString (SIZE (0..255)) MAX-ACCESS read-write

STATUS deprecated

DESCRIPTION

"This variable emulates TrueTime's serial function command strings. The same commands issued to the serial port can be sent to this string. Use this variable for SNMP sets of functions strings.

Note, setting this variable clears ntpControlOutput to the null string. See ntpControlOutput below."

::= { ntsControl 1 }

ntpControlOutput OBJECT-TYPE

SYNTAX DisplayString (SIZE (0..255)) MAX-ACCESS read-only

STATUS deprecated

DESCRIPTION

"This variable emulates TrueTime's serial function command strings. The same commands issued to the serial port can be sent to this string. This variable holds the output result string from the last setting of the above ntpControlInput variable. Use this variable for SNMP gets of function strings. See ntpControlInpuut above."

::= { ntsControl 2 }

gpsGroupValid OBJECT-TYPE SYNTAX INTEGER (0..1) MAX-ACCESS read-only STATUS deprecated

DESCRIPTION

"A test flag indicating if data contained in this SNMP GPS group is valid or not. This flag equals 1 when GPS is used as the time synchronization source and 0 for all other sources. "

::= { gps 1 }
