RSP-APA-002 User’s Manual R-tron., Inc. 3/34 page 1. Overview Figure 1.1 RSP-APA-002 Repeater R-tron RSP-APA-002 Repeater can be used in CDMA service hole spots like in-buildings, underground and tunnels to cover its service area. This repeater system designed for dual and simultaneous service, namely, it receives signals from the base station through donor antenna, amplifies the signals and re-transmits it to one or other mobile terminals. Also, it amplifies the signals which comes from mobile terminals through distributor antenna and re-amplifies it to base station. Using local OMT(Operation and Maintenance Terminal) which is connected between repeater control board and personal or laptop computer, it is possible to check or to control repeater status. With wireless modem which is in the repeater, it also enables to monitor Sprint WNMC(Wireless Network Management Center) in a remote place.

Figure 5.17 Alarm Mask Window 5.3.8.3 ALC (Auto Level Control) Setting This function lets you control ALC settings and the ON/OFF status. To change a setting, you need to enter a value and click the SET button at the lower part of the Control Window. ▶ If the ALC gets activated with system output exceeding ALC Target values, you need to use the USER ATT to adjust the output to meet the range of the upper settings. If the output exceeds the Attenuation range (30dB), the ALC FAIL alarm will occur. If the system output exceeds the Shutdown Target value due to lack of attenuation, then the ASD (Auto Shut Down) will be activated. If output exceeds the Shutdown target values and makes the repeater shut down, the repeater
RSP-APA-002 User’s Manual R-tron., Inc. 29/34 page goes back to the active status after the ‘Shutdown-on’ time. If the output of the repeater is higher than the set target value, the repeater will be de-activated again after the set ‘Shutdown-off’ time. The repeater repeats the process by the Shutdown count. If the output of the repeater still exceeds the target value after the repetitive work, the repeater will turn completely off. Figure 5.18 ALC Setting window 5.3.8.4 Time set When you press the Time set button at the menu window, the window seen in Figure 5.19 appears. When you click the Set button in the window, MCU automatically reads the time of the PC for time setting. The set time appears on the RTC Time on the SYSTEM window [See the Figure 5.8]. Figure 5.19 Time set window 5.3.8.5 Reset This function clears communication status, rebooting the MCU. When you press the Reset button, current communication status is reset.

RSP-APA-002 User’s Manual R-tron., Inc. 31/34 page 1. Modem system window ▶ General control - Communication Port : Connects MCU to the modem port. You can refer to the same settings as those in the main GUI. - Modem own number : Refers to the modem number, with which you can call using a modem. - Firmware version : Refers to the version of currently used software. ▶ WNMC configuration - Cascade code : Refers to the ID designated by operator where the repeater is installed. The ID is composed of ten-digit characters and figures. It may appear in the following form: XX##YY$$$$ 　① XX : First two-digit characters showing the installation site of the repeater. If the repeater is installed in Boston, XX is seen as ‘BS’. ② ## : Shows whether the repeater is installed inside/outside of a building: In Building System (Indoor type)/Macro System (Outdoor type). 　 ③ YY : Shows device types (Repeater/cell site). If the system is found as repeater, YY is ‘XR’; if it is a cell site, YY is ‘XC’. 　 ④ $$$$ : Refers to integers (1 ~ 9,999) indicating the number of repeaters installed in XX. If 24 repeaters are installed in Boston (BS), $$$$ is ‘24’. ▶ Control The Control window is to set the periodic interval of the Heartbeat. This function lets you set the time interval of the Heartbeat to 3 ~ 59 minutes. ▶ Modem Configuration - Network Connection : ① Modem mode : This button lets you see the modem status. When you press the button, the Modem Status window, the Modem Configuration window, the Modem Statistics window, and the Modem Status window are activated. With the [NMST] button in the Modem Status window, you can see modem status. ② PPP mode : Stands for Point to Point Protocol, which helps set connection between the MCU and WNMC. PPP connection is automatically set. Facing connection failure, MCU retries until the connection is successful. When PPP is fully set, the Modem Status window, the Modem Configuration window, and the AT Command window are automatically de-activated. ③ WNMC : This button lets you clear PPP connection. You can see whether PPP is connected/disconnected depending on the icon color of the WNMC button. You can see the connection status in the window next to the WNMC button. You can have access to the PPP
RSP-APA-002 User’s Manual R-tron., Inc. 32/34 page and verify the ‘Disconnected’ status and press the “WNMC” button. At this time, you need to check if the status window next to the “WNMC” button is changed: Disconnected ->calling-> PPP Connected. If the connection fails to be set in 60 seconds, the status will be ‘Disconnected’ due to timeout. In this case, you can press the “WNMC”button again to set the connection. With PPP set, MCU is connected to the Internet, enabling SNMP Trap messages to be sent to WNMC whenever alarms and Heartbeats occur. - Program Download : Lets you download a new firmware version to the MCU when firmware is upgraded. Downloaded files should be in Binary format and downloading methods are split into Ack and NoAck. ① Download(AcK) : Receives AcK (acknowledge messages) for each message that is transmitted to calculate Check Sum. When errors are generated during file transmission, the transferring will be immediately stopped. This method requires roughly one more minute than the NoAcK method. ② Download(NoAcK) : Calculates Check Sum for each message that is transmitted when AcK may not be received. AcK messages are received when the transmitted messages are completely sent. This method reduces one minute to download than the Ack method. Figure 5.22 Modem Status Window 2. Modem system window ▶ Modem status - NMST button : Refers to AT command to report current modem status with AT + NMST commands programmed in the button. When you press the button, modem status information is displayed. - Analog / Digital : Shows transferring methods of the modem (Analog/digital types). When the modem uses analog communication method, ‘Analog’ is displayed; if it uses Digital
RSP-APA-002 User’s Manual R-tron., Inc. 33/34 page communication method, ‘Digital’ is displayed. - Lock Mode : Shows whether the current modem is locked/unlocked. ‘Locked’ means the current modem is locked; ‘Not Locked’, the modem is unlocked. - Service : Shows whether the current modem is available for calling. ‘No Service’ means the modem is not available; ‘In Service’ means the modem is available for you to try a call. - SMS(Short Message Service) : Refers to the two-way wireless data-calling service according to GSM (Global System for Mobile Communications), sending data at up to 150-byte length between terminals. Using this service, you can send/receive messages composed of characters and/or figures between terminals or networks. This service type includes short message transferring, emergent message indication, date/time recording, and message indication. SMS has two status of “None” and “Exist”: “None”means there are no received SMS messages; “Exist” means SMS messages have been received. - Missed Call: Refers to the count of failed communication trials by the modem. - Service System : Consists of three items of “Band Class”, “Band”, and “System ID”. ▶ Modem statistics This window enables you to manually control the modem using AT commands. Seen in the modem statistics, such protocols as RLP, TCP, UDP, PPP, IP, and RLP3 are supported by a built-in operating system (Installed in protocol stacks including integrated RLP, TCP, UDP, PPP, IP, RLP3, etc.) installed in MCU. Using the protocols, the modem can have access to communication network.
