introduCtion
The xMAX BSN-250 VoIP Base Station is a three-sector, 18-channel system used to communicate with xMAX
handsets and modems operating in the 900 MHz band. The BSN-250 is preconfigured with all software
required to transmit and receive voice and data to and from xMAX handsets and modems. This guide provides basic information on how to install, configure, and operate the base station.
ATTENTION: This symbol is used in this guide to draw attention to precautionary steps and
safety-related instructions. Failure to follow these instructions may result in a safety hazard
and/or damage to equipment.

rack that is at least 18 inches deep and 15U high.
ATTENTION: Be sure to follow proper safety precautions when lifting heavy equipment.
2. Two 10/100 Mbps RJ-45 Ethernet connectors are installed on the rear of the control unit. The Ethernet
ports are used to connect the base station to the backhaul network and the xMSC. Connect the Ethernet
cable to the control unit, as shown in Figure 2.

3. Install the 36 RF cables as shown in Figure 2.
4. Install the six Digital RF Interface (RJ-50) cables as shown in Figure 2.
5. Install the 18
cables from the RF unit to the three sector units
as shown in Figure 2.
6. Connect the DC power cables from the power supply unit to the corresponding ports on the control unit
and the RF unit as shown in Figure 2.
7. Connect the N-Type connectors for the antenna leads as shown in Figure 2.
This system has four antenna ports, one for each of the three sector units and one for the GPS antenna.
The ports for the sector units are located in the center of the back panel of each unit. The GPS antenna
port is located on the lower right corner of the back panel of the control unit.
The antenna port for sector unit 1 must be connected to the antenna pointing south of the tower. The
antenna port for sector unit 2 must be connected to the antenna pointing toward azimuth 60°, and the
port for sector unit 3 must be connected to the antenna pointing toward azimuth 300°.The GPS antenna
port must be connected to a GPS antenna.
The impedance of the chassis mount BNC female connector is 50 ohms. For proper operation of this
device, this connector should be connected to a 50 ohms coaxial cable with BNC male connector.
Any 50 ohms coaxial cable with a male BNC connector on one end and antenna on the other end
can be used. However, the recommended coaxial cable is LMR-900. The recommended antennas for
3 sectors are 900MHz 90° antennas vertical with gain better than 6dBi. The antenna for the GPS is
not required at this point. Additional details are included in xG Network Implementation Guide. Please
contact your xG sales representative for access to this document.

8. Connect the AC power cable to back of the power supply unit before connecting to the power outlet.
The BSN-250 operates on 100V/240V AC, 50/60Hz and single-phase AC power line. The device is
connected to the AC power line using a standard 3-prongs power connector. This is shown in Figure 3.
ATTENTION: Be sure to follow proper safety precautions when working with electric power cables.
9. Toggle the back power switch to ON, as shown in Figure 3.

ATTENTION: Before turning ON the system, be sure you have connected the antennas using the
recommended coaxial cable to the chassis mount BNC connectors installed on the rear of
the unit. The cables and antennas serve as a load to the xMAX BSN-250. Never turn the
system ON without first installing the cable and antennas.

powering on the xmax bsn-250
After the components of the base station are correctly mounted in the rack, follow these steps to turn the
system ON:
1.
2.
Make sure the data, DC power, and antenna cables are connected to all units, the AC power cable
(240 V main line) is connected, and the back power toggle switch is flipped ON, as detailed in the
section Installing the xMAX BSN-250.
Flip the front power switch to the ON position. The red AC power lights on the power supply unit
indicate when the AC power is ON.
ATTENTION: Before turning the device ON, connect the antennas using the recommended coaxial
cable to the chassis mount connectors installed on the rear of the sector units. The cables
and antennas serve as a load to the xMAX BSN-250. Never turn the unit ON before
installing the cables and antennas.
3. During power up, all LED indicators are turned on. As the control unit goes into boot mode, the System
LED will remain yellow while the other LEDs are turned off. When the control unit processor enters runtime mode, the System LED turns green if no faults are detected. Otherwise, the System LED turns red
if faults are detected or if the control unit processor is unable to communicate with the i.MX. See the
section Front Panel Status Indicators for the possible colors and meanings of the LEDs on each unit.
4. Verify that both the System LED and Link LED indicator lights on the control unit are green. The base
station is now ready for initial configuration.

Configuring the xmax bsn-250
Upon initial installation, the base station must be configured manually to work with the network. This section
describes how to connect to the base station and use the base station’s command line interface to perform
initial configuration of the Ethernet network interface and the serial interface. After performing these steps,
the base station provides a Web-based interface that is used to finish configuration of network, make cable
and channel settings, and to make adjustments for optimal performance.
A serial port on the front of the control unit allows for connection to a VT100-compatible terminal or other
device through any terminal emulator that supports VT100 terminals. To connect to the base station:
1.
With the base station ON or OFF, connect the serial cable to the VT100-compatible terminal or other
device.
With the base station ON, turn the VT100-compatible terminal ON or start the terminal emulation
2.
program on the device.
Select the COM port and port speed.
3.
At the command prompt, use the
4.
ifconfig command to enter the base monitoring entity (BME) IP
address, which is the IP address for the base station: ifconfig eth0 <BME IP address>
Consult your network administrator for the IP address assigned to this BSN-250.
5. Use ifconfig again to enter the subnet mask for the Ethernet interface. Consult your network administra-
tor for the subnet mask assigned to the network.
6. Use ifconfig to enter the IP address of the gateway device on the backhaul metropolitan network that
provides access to other devices on the network, such as the xMSC. Consult your network administrator
for the IP address of the gateway.
