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.
SNMP Enable 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", both GB2PP and SNMP protocols are supported.
Note: It is strongly recommended to disable the SNMP protocol if only the
GB2PP protocol is used.
E1 Alarm for Inactive
Warning The parameter is used to enable/disable the transfer of the inactive
warning via the E1 interface.
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 0301 and 0401, 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 0302 and 0402, 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.
VoIP radio URI RX This is the unified identifier for VoIP communication of the RX module. This
identifier consists of two parts concluded with the “@” sign
user@<IP Address>
or user@<Full Qualified Domain Name> eg.
