1.1 BS411 BASE STATION - 8 CARRIER

Description

DAMM BS411 is a 8-carrier TETRA indoor base station and is complementary to DAMM

BS421 and DAMM BS414 TETRA base stations. The BS411 may be used in networks where

high traffic capacity is required (up to 31 Erlang).

It is designed for a fully IP based connectivity and allows for remote supervision and

diagnostic, test, control, setting and software update, file transfer and SNMP. Its embedded

Operate & Maintenance (OM) system is reached by means of Windows desktop.

The BS411 support discontinuous transmission fully GPS synchronized. This allows a

dramatic decrease in power consumption, as only the active TR412 (‘s) needs to be

powered, until traffic load requires more carriers to be on air.

BS411 fully supports Voice + Data services in full and half duplex modes, compliant with the

ETSI EN 300 392

Access to all field replaceable units (FRU) is from the front, protected by a lockable door, and

all external connectors in located on top of the rack.

Date D100300-REF 1.02 2012-10-09 BS411 Base Station The BS411 consist of the base station controller, the transceiver modules, the combiner system and the filter system. In the receiver path a separate Tower Mounted Amplifier/Duplexer (TMD412) is an integrated functional part of BS411. The TMD412 is intended for mast/tower mounting.

The AI411 Antenna Interface unit is used in all Base Station (BS411and BS414) and contains all the necessary circuit to support a complete Radio Cell including support of the Tower Mounted Amplifier/Duplexer TMD412 with all functions. The two independent RX multi-coupler amplifiers are built with low-noise high dynamic range transistors.
