BTS3900 GSM Site Maintenance Terminal Guide

About This Document

2 Getting Started with the Site Maintenance Terminal This describes how to connect the Site Maintenance Terminal PC to the BTS, to the Site Maintenance Terminal System, and exit the Site Maintenance Terminal, after the Site Maintenance Terminal application is installed. 3 Using the Site Management Rights The operations of the site management rights involve obtaining the site management rights and releasing the site management rights. 4 Managing Sites The site management involves viewing site resources, querying the delay in reporting board alarms, resetting the BTS, testing whether the boards in a site operate normally and whether the connection of transmit links is normal, monitoring and managing the environment parameters in a site, viewing the board parameters of the BTS, testing the RF specifications, and viewing the settings of parameters in a ring network and the bar codes of a site. 5 Managing Cells The cell management involves managing cell attributes and cell extended attributes, testing all the BTs and RCs of a cell so that they can be locked or unlocked, and checking whether the BTs and RCs are functional. 6 Managing BTs The BT management involves locking or unlocking a BT, resetting a BT, performing the RC self-test, view the status of the channels on a specified BT, and enabling a specified RC to transmit signals at a predefined power level. 7 Managing RCs The RC management involves setting the attributes and extended attributes of an RC, locking or unlocking an RC, resetting an RC, and adjusting power of an RC automatically. 8 Managing Channels The channel management involves viewing and setting channel attributes, locking or unlocking a channel, and checking the quality of a channel by testing the parameters such as the bit error ratio (BER) and transmit power. 9 BBU Operations The BBU operations involve the query, configuration, and test operations associated with the BBU. You can query the board settings, board information, board extended information, board alarms, and port attributes. You can also perform operations such as board reset, power-off reset, self-test, clock configuration, loopback test, and parameter management. 10 DRFU Operations DRFU operations include the viewing, setting and testing of the DRFU parameters. You can view the board information, board extended information, and board alarms. You can also perform operations such as the board reset, power-off reset, operation start, self-test, loopback test, parameter management, and antenna mode configuration. 11 DRFU Configuration This describes how to perform various operations on the DRFU based on the actual requirement, such as adding or deleting an DRFU, adding or removing a ring, displaying in-position boards, detecting in-position boards, setting and canceling a breakpoint. 2

The test device (for example, a base station integrated tester) is connected to the ANT port on the DRFU.

Context A base station integrated tester is required to test the RF specifications. Pay attention to the following points before the test: l

Before the test, you need to reset the configured RC by clicking -defined Message. –

If the E1 cables are connected, after the configured RC is reset, you can observe the RUN LED on the DRFU to check whether the RC is running normally. If the RC is running normally, you can perform the test.
