TX Preemphasis
For the use especially with long telephone lines, the AF response shape
can be adjusted in a way that higher frequencies have higher gain than
lower frequencies. The value in dB specifies the gain at AF = 3400 Hz in
comparison to AF = 800 Hz. Nominal TX audio level is always related to
AF = 1 kHz. Default value is 0 dB which means that TX preemphasis is off.
SNMP Community
String
Name of the SNMP communication community. It is used to restrict the
network access.
Enable SNMP
The parameter is used to enable and disable the SNMP functionality of the
radio on the LAN interface.
If the parameter is set to "Disable", the SNMP functionality is disabled and
only GB2PP protocol is supported via LAN. If the parameter is set to
"Enable", only the SNMP protocol is supported.
Note: Parallel usage of the SNMP and GB2PP is not supported.
Note: For a proper use of the SNMP protocol, it is necessary to update the
access control list (ACL).
DC-Battery
Supervision
The voltage during battery operation can be monitored. If the voltage is too
low, two responses in the radio can be triggered.
The Warning setting generates the CBIT warnings 301, which are output
via the remote system connected.
The NOGO setting sets the TEST_OC signal at the output
(connector X5.4) and initiates a switchover to the standby mode in
a main/standby configuration. This setting is recommended if, for example,
two separate DC networks are used for the main and standby radios.
AC-Main
Supervision
The voltage during network operation can be monitored. If the voltage is
too low, two responses in the radio can be triggered:
The warning setting generates the CBIT warnings 302, which are output
via the remote system connected.
The NOGO setting sets the TEST_OC signal at the output
(connector X5.4) and initiates a switchover to the standby mode in
a main/standby configuration. This setting is recommended if, for example,
two separate AC networks are used for the main and standby radios.
Note: If the AC-Mains fail, operation automatically switches to the standby
radio. Otherwise the DC battery of the main radio would be
unnecessarily discharged.
Local Mode Warning
The radio can be configured in such a way that pressing the LOC button on
the radio generates the CBIT warnings 336, which is output via the remote
system connected.
USB Connect Warning
The radio can be configured in such a way that a USB access via a service
PC generates the CBIT warnings 335, which is output via the remote
system connected.
