2 Getting Started with the Site Maintenance TerminalThis describes how to connect the Site Maintenance Terminal PC to the BTS, log in to the SiteMaintenance Terminal System, and exit the Site Maintenance Terminal, after the SiteMaintenance Terminal application is installed.3 Using the Site Management RightsThe operations of the site management rights involve obtaining the site management rights andreleasing the site management rights.4 Managing SitesThe site management involves viewing site resources, querying the delay in reporting boardalarms, resetting the BTS, testing whether the boards in a site operate normally and whether theconnection of transmit links is normal, monitoring and managing the environment parametersin a site, viewing the board parameters of the BTS, testing the RF specifications, and viewingthe settings of parameters in a ring network and the bar codes of a site.5 Managing CellsThe cell management involves managing cell attributes and cell extended attributes, testing allthe BTs and RCs of a cell so that they can be locked or unlocked, and checking whether the BTsand RCs are functional.6 Managing BTsThe BT management involves locking or unlocking a BT, resetting a BT, performing the RCself-test, view the status of the channels on a specified BT, and enabling a specified RC totransmit signals at a predefined power level.7 Managing RCsThe RC management involves setting the attributes and extended attributes of an RC, lockingor unlocking an RC, resetting an RC, and adjusting power of an RC automatically.8 Managing ChannelsThe channel management involves viewing and setting channel attributes, locking or unlockinga channel, and checking the quality of a channel by testing the parameters such as the bit errorratio (BER) and transmit power.9 BBU OperationsThe BBU operations involve the query, configuration, and test operations associated with theBBU. You can query the board settings, board information, board extended information, boardalarms, 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 OperationsDRFU operations include the viewing, setting and testing of the DRFU parameters. You canview the board information, board extended information, and board alarms. You can alsoperform operations such as the board reset, power-off reset, operation start, self-test, loopbacktest, parameter management, and antenna mode configuration.11 DRFU ConfigurationThis 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.
