1. Overview

HB(Heart Beat)1900 is designed for the purpose of checking the repeater systems which were

installed in Sprint network.

Using CDMA 1x modem protocol, heartbeat is happened only when the repeater system

operates correctly. It traces the repeater status and give heartbeat signal periodically to WNMC

server through SNMP Trap.

The SNMP Board located in the HB 1900 cabinet which is the essential of the HB 1900.

The SNMP board contains powerful microprocessors.

Operational parameters, such as Heartbeat interval, Modem Attenuation, SNMP version, Site ID,

etc. are set using a desktop or notebook and OMT, which communicate, locally via RS-232C

cable, with the RRMS. Remote operation is performed via CDMA net

4. Installation

4.1 How to install Program File

GUI program consists of one exe file. Therefore, you can copy one exe file to your PC and use it.

R-TRON Proprietary & Confidential Page 11

4.2 Connect communication cable

Connect communication cable as followings,

4.3 Power on

After connecting the communication cable, you can supply AC power to the HB 1900. As you

can see the following picture, when you supply AC power to the HB 1900, the DC 5V LED light

up one time. After 3 or 4 seconds later, the modem power(3.3Voltage) LED light up two times.

Then 10 seconds later, the LED light three times. This signals that the heartbeat unit is ready for

communication. Finally, you can execute GUI program and get the heartbeat communication

started.

4.4 How to start GUI Program

Click HB 1900 v1_2.exe.

R-TRON Proprietary & Confidential Page 12

When you click HB 1900 v1_2.exe, you will see the following pop-up window.

4.5 How to use and configure the Graphic User Interface (GUI)

4.5.1 Login / Logout

To proceed using the GUI Program, a user should log-in.

There are two kinds of users. One is the‘root’ and the other is the‘operator’. The ‘root’ user, the

can control all GUI buttons but the ‘operator’, can not use debugging pop-up window. Input

classified user IDs(‘root’ or ‘operator’) and assess password. After that,all default buttons will be

activated.

4.6 How to set up a communication port

After setting up the GUI Login, you should set up the communication port between the system

R-TRON Proprietary & Confidential Page 13

and GUI. The Communication protocol is a RS-232C protocol between the SNMP board and the

PC serial port which is set up by the GUI. The Current RCU transmit speed is fixed at

11,5200bps. As you can see in the above picture, you can select the proper COM port and then

click the ‘START’ button. Now the RCU communication is started. If there is no problem with the

communication, the Rx LED will light up green with the Tx and Rx lighting up green, alternately.

4.7 Check setting figures

As shown in the above picture, you can check the Site ID(Cascade Code) , WNMC Phone

Number , WNMC IP Address , SNMP Version and Modem Phone Number. When you change

the current GUI settings, you can input the needed numbers in the white boxes and click toggle

switch to store the values.

4.7.1 How to set Parameter value

4.7.1.1 Cascade code Input

ex) Cascade Code which is given by a wireless operator : test01

Type Cascade code in white activated box. Click “SiteID Set” button.

R-TRON Proprietary & Confidential Page 14

4.7.1.2 Input WNMC Phone Number

Sprint WNMC Phone Number is #777 and procedures is as followings,

Type “#777” in white activated box Click “Phone Number Set” button

4.7.1.3 WNMC IP Address입력

Sprint WNMC Server IP Address는 10.22.25.15 and procedures is as followings,

Type “10.22.25.15” in white activated box. Click “IP Address Set” button.

R-TRON Proprietary & Confidential Page 15

4.7.1.4 Input Modem Phone Number

Type modem phone number which you are going to put it into HB 1900.

Each modem phone number is different.

For example, when it comes to modem phone Click “Modem NUM Set”

number is 5022759735, type this number

in white activated box.

2.4 How to check Modem

You can set the network connection status in ‘modem mode’ using the modem status pop-up

window and entering information in the ‘modem statistics’ pop-up window as followings,

R-TRON Proprietary & Confidential Page 16

① When the Modem is properly connected, you will see ‘READY’ im green, like in the

above picture[number 1].

② Then you can click the NMST button [number 2] and test the AT Command. When

you see the ‘OK’ response, this means that the modem and SNMP board status is

Okay.

2.5 Check RSSI Value and Set Attenuation

2.5.1 Set Attenuation

After check the RSSI value which is displayed on the GUI, set the RSSI value as -70dBm, using

the modem attenuation. For example, when the GUI RSSI value is -67dBm, you can set it as -

70dBm, using the modem attenuation 3dB. To set the attenuation, you can input the attenuation

value in white box and then click the ‘modem atten’ button which is located on the left side to

store it. (Ex-factory setting value of HB 1900 : user attenuation is 12dB , Heartbeat interval is

5 minutes.)

Ex) How to set User Attenuation

Antenna input Level Fixed Loss User Attenuation Reference RSSI Value

-30dBm -15dB -25 dB -70dBm

-40dBm -15dB -15 dB -70dBm

-50dBm -15dB -5 dB -70dBm

R-TRON Proprietary & Confidential Page 17

2.5.2 Set Heartbeat Interval

Type heartbeat interval in white Click “Heartbeat Interval” button.

activated box.

(Heartbeat Interval Range : 3 ~59 min)

2.6 How to check PPP connection and heartbeat

Set heartbeat interval as 20 minutes and then change network connection status to ‘PPP Mode’.
