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."
::= { ntp 14 }
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 }
