Remote server:
Remote server is the intermediate daemon which forwards the telemetry received from the GSED to
the clients (i.e the web browsers). Normally this field should display text 'Alive'.
GSED is the software daemon receiving the SOHO telemetry from the SOHO EOF Core System.
The 'Remote server' is located at the University of Turku, Finland.

GSED connection:
GSED connection status provides information about whether the link between the GSED and
the 'Remote server' is active. Normally this field should display text 'Established'.
GSED is located at the University of Turku, Finland.

NRT TLM session:
NRT TLM session provides information about whether the link between the GSED and
the SOHO Experimenters' Operations Facility (EOF) Core System is active. Normally this field
should display text 'Initialized'.
EOF is located at the Nasa GSFC premises Maryland USA.

H/K TLM sync:
Field 'H/K TLM sync' provides information whether the telemetry (TLM) stream from the SOHO spacecraft
to the GSED is synchronized or not. Synchronized means that all the Housekeeping telemetry
packets sent by the CEPAC instrument onboard SOHO spacecraft are received in chronological
order and none of the packets is lost or duplicated during the transfer. Hence, the CEPAC
'Housekeeping minute buffer' can be assembled by the GSED without any errors. Normally this
field should display 'OK'.

DSN contact:
DSN refers to the Nasa's Deep Space Network which is telecommunications array of radio
antennas and which provides communication link to various spacecrafts (including SOHO).
This field shows the DSN contact information between the DSN and the SOHO spacecraft, thus
indicating whether the data shown is accurate (in contact) or outdated (out of contact).
Note the status of the field 'H/K TLM sync' too and TLM packets' arrival times.
