OM Equipment

The OM equipment performs the OM functions of the BTSsuch as security management, alarm

management, data configuration, and maintenance management. The BTS3012 supports three

OM modes: Site Maintenance Terminal, LMT, and Network iManager.

Auxiliary Equipment

The BTS3012 can be configured with the auxiliary equipment such as 3.1 Sidepower, 3.2

EMU, and various sensors. The auxiliary equipment converts the power supply, monitors the

environment of the equipment room and the BTS, and reports environment alarms.
