4.3 AN-30e Terminal
The front panel includes the Ethernet port, the TDM ports, and three groups of LED
indicators: System, Wireless, and Ethernet. The rear of the terminal includes the
power supply connections, the IF port, the serial console port, and a BNC connector
for the time synchronization signal (future release).
4.3.1 Mounting
The terminal can be freestanding on a flat surface, or mounted into a standard 19-inch
equipment rack.
4.3.2 Power Supply
The AN-30e power supply connections are provided on the rear of the chassis.
Separate connections are provided for each power supply.
Grounding Connection
A ground connection terminal is located on the back of the AN-30e system. Correct
grounding is very important for safe operation of wireless equipment. Refer to the
installation section for additional information.
System Fuse
Removable fuses located at the rear of the terminal protect the system power inputs.
Refer to section 7.5: Replacing System Fuse on page 75 for additional information.
4.3.3 Time Synchronization Port
The AN-30e has one BNC input on the rear panel for time synchronization. This port
accepts a standard IRIG-B signal (1 pps) from a GPS satellite clock. This port is
currently disabled and is enabled in a future software release.
4.3.4 Wireless Section
This section describes the wireless port and LEDs.
IF Port (Radio Control)
The terminal has a female F-type connector (rear of chassis) for interconnection with
the system radio.
The IF cable carries the following signals between the terminal and the radio:
- OFDM IF signal at 815 MHz
- Local Oscillator (LO) signal at 2.5 GHz
- 24 Volt DC voltage for the transceiver electronics
- Control signal between IDU and ODU
