<h2>User interface</h2>

<p>The network element's local user interface is usually an
option to using the Graphical User Interface (GUI) from Nokia NetAct. The
whole GSM network can be managed through Nokia NetAct GUI.</p>


<p>A standard terminal (VT 52 or VT 100) is used as a network
element's man-machine interface (MMI) terminal. Nokia Base Station Controller
(BSC) and Nokia Transcoder Submultiplexer (TCSM) have a user-friendly interface
with plaintext messages and man-machine language (MML) commands, which are
easy to learn and use. The user interface complies with the recommendations
of the International Telecommunication Union (ITU-T).</p>


<p>The Base Transceiver Station (BTS) equipment can be controlled
locally at the site by the user, via Nokia BTS Manager or remotely by Remote
BTS Manager. Nokia General Communication Server (GCS) SW Suite is used for
providing both local and remote connections to the BTS.</p>


<p>Nokia BTS Manager has a graphical user interface and runs
on a PC in Windows environment. The PC is connected to Nokia BTS Manager via
the local management port (LMP) on the BTS interface unit. Nokia BTS Manager
is used for commissioning the BTS and for carrying out maintenance functions
locally at the BTS.</p>


<p>Remote BTS Manager enables the monitoring and testing of
the BTS remotely, by connecting to the BTS via Network Management System (NMS/2000)
or NetAct. A PC with the BTS Manager software is used as a user terminal.</p>


<p>It is not possible to perform the BTS commissioning remotely,
because the BTS must be commissioned before the BSC is able to send remote
BTS Manager commands to it.</p>


<p>Element Managers (also called Node Managers) are used for
operating, commissioning and carrying out maintenance functions on different
transmission elements. Transmission managers include: FXC STM-1 Manager, FXC
Bridge Manager, FXC RRI Manager and Nokia E1/T1 Manager.</p>


<p>Related transmission managers include: Nokia MetroHub Manager,
UltraSite BTS Hub Manager, Transmission Loader (Tresman), FXC E1/T1, FXC RRI
Manager and FC STM Manager.</p>
