ACARS Data Mode With this parameter the radio can be configured for voice (disabled) or
ACARS data operation (enabled) (2400 Bps).
The Voice setting is optimized for voice processing and squelch muting.
The ACARS setting available for receiving ACARS data. In this case a
faster RF front-end control is in action. The attack and decay time is in
accordance with the ETSI EN 300676 standard.
If the radio is operating in ACARS data mode, only the 25 kHz spacing can
be used and the parameters RX Audio AGC and TX Audio ALC must be
deactivated.
Select Audio Interface This parameter is used to select the audio interface of the radio. If the
Analog Audio is selected, the RX Audio Basic interface X10/TX Audio
Basic interface X5 is used. If the E1 is selected, the E1 – Communication
Data interface X13 is used. For more information on E1 interface please
refer to chapter 3.12 Audio via E1 Interface. If VoIP is selected, audio data
will be transmitted via Ethernet by the data interface X6 (RX), X9 (TX) (see
chapter 3.15) and TX Audio Basic interface X5. For parallel operation of
VoIP and Analog Audio interfaces, please see chapter 3.15.9 Parallel
Operation of the Analog and VoIP Audio Interfaces.
RX Input Sensitivity There are two settings for the sensitivity of the transceiver:
The Low Distortion (LD) setting is recommended for strong interference
signals at the antenna input. It reduces sensitivity, and thus improves
immunity.
The Low Noise (LN) setting increases the sensitivity, and thus improves
the reception of weak signals.
Set/Get Values for
Preset Page 200 preset pages can be stored in the radio and called up. Each contains
the frequency and spacing parameters. These parameters can be set for
each preset page.
Installation Info Information (up to 20 characters) can be entered to describe the radio
more precisely.
Location Info Only the first 20 characters entered by using the R&S ZS 4200 appear on
the radio display.
IP Address An IP address must be assigned for each radio module, which allows each
module to be uniquely identified and operated in remote operating mode.
Additionally, specifying the netmask and the gateway makes it possible to
work within different subnets via a router.
ACL
(Access Control List) Here you can enter the IP addresses of the remote control systems or
clients that are allowed to access the radio. This protects the radio against
unwanted/unknown accesses. If the list is blank (default), then any client
with any IP address can access the radio.
BSS Enable
The parameter is used to enable or disable the Best Signal Selection
functionality. For more information please refer to chapter 3.11 Best Signal
Selection.
