Transport Module (TM)
The cabinet contains a compartment, called the Transport Module (TM),
for mounting other transmission equipment. Examples of transport
network products installed here may include indoor interfaces for Mini-
link, line terminals, higher-order multiplexors, radio link control units
or fiber-optic cable interfaces.
The TM-box is a standard 19” rack according to the standard
DIN 41494. Dimensions of the rack are
266 mm high X 395 mm deep X 449 mm (19 inches) wide between the
vertical mounting rails.
Power can be +24 V DC, –48 V DC, or both. A DC/DC converter is
required for –48 V DC power; the RBS 2106 can be equipped with two
DC/DC converters to obtain redundancy in the power supply.
Maximum power consumption for the various supply voltages are given
in the following table.
Table 52
Maximum power consumption of equipment installed in TM box
Supply
Maximum Power Consumption
+24 V DC
2 x 250 W
–48 V DC
2 x 200 W
Simult24 and –48 V DC
500 W (system total)
The maximum allowable heat generated in the TM space is 300 W.
Equipment in this compartment must fulfill the following
Electromagnetic Compatibility (EMC) requirements:
•
ETS 300 342–2, the BTS product standard, in accordance with the
European EMC Directive 89/336/EEC.
•
FCC, part 15.
If equipment is not installed in the TM, the unused module positions
must be covered with dummy front panels for balanced airflow
throughout the cabinet.
