Energy Efficient Ethernet (OpenScape Desk Phone CP205/CP400/600 only)
The OpenScape Desk Phone CP205/400/600 phones support the standard IEEE 802.3az (En-
ergy Efficient Ethernet).
The energy saving benefit provided by this standard can only be received when the phone is
connected to a network component which also is able to support the IEEE 802.3az standard.

Date and Time
To ensure that HFA security operates properly, the phone must obtain the correct date and time
before logging on to the system. For this purpose, the phone must use the same SNTP server
that is used by the system/PBX. If the DHCP server in your network provides the IP address of
the SNTP server, no manual configuration is necessary. If not, you have to set the
SNTP IP
address
parameter manually.
The date and time to be displayed can be obtained either from the SNTP server or from the
system/PBX. To select SNTP-based date and time, set the
Time source
parameter to "SNTP".
The default value is "System".
For correct display of the current time, the
Timezone offset
must be set appropriately. This is
the time offset from UTC (Coordinated Universal Time). If, for instance, the phone is located in
Munich, Germany, the offset is +1 (or simply 1); if it is located in Los Angeles, USA, the offset
is -8. For countries or areas with half-our timezones, like South Australia or India, non-integer
values can be used, for example 10.5 for South Australia (UTC +10:30).
If the phone is located in a country with daylight saving, the administrator can choose whether
daylight saving time is activated manually or automatically. If
Daylight saving
is enabled, and
Auto time change
is disabled, daylight saving time (DST) is in effect immediately. If
Auto time
change
is enabled, daylight saving is controlled by the
DST zone
parameter. This selects the
daylight saving timezone which is characterized by the start and end date for daylight saving
time.
The
Difference (minutes)
provides the time difference for daylight saving time in minutes. This
parameter is required also when
Auto time change
is enabled. In Germany, for instance, as in
most countries, this is +60.
The
Current DISPLAY Time
is the date and time according to the timezone and daylight saving
settings; this date and time is presented to the user. The
Current UTC Time
is the UTC time
used by the phone and the system internally.
