Mobile Gateway S20
The
CAU
(if installed) is a Carrier Unit. This module offers three plug in spaces for
expansion boards. Both BRA or PRA or a combination of both types of expansion boards
can be inserted.
Usually the BRA interfaces are not provided with 42 Volts ISDN line power. If you want
to connect a BRA interface to an item of terminal equipment that also needs a power
supply from the BRA interface, it will be necessary to use a DC4. The DC4 is a seperate
slide in module, that will provide the necessary voltage to power terminal equipment
connected to the BRA interface. This module is simply added to the existing modules by
inserting it into a slot in the rack.
The Antenna Combiner Unit
(ACU)
gathers the output of the WAU cards to one RF output.
This RF output shall be connected to the next ACU input or directly to the outdoor antenna
(the number of the possible cascade stages is location pendant. For more information please
contact NovaTec). The ACU contains 4, 8 or16 inputs. 15 inputs shall be connected to the
RF outputs of the WAU’s (in a 60 channel configuration) or should be terminated by RF
termination resistors (please consolt NovaTec).
Please note:
Never run the system without antenna! Do not leave any RF input without
termination!
The
SXU
is an additional module which is used in conjunction with the WAU. In this
combination the SXU allows the number of Simcards per channel available to the WAU
according to configuration parameters to be chosen between 1 and 5 Simcards per channel.
The Sim-Combiner-Unit
(SCU)
corresponds optically to the SXU. The Status Displays of
the SCU are different than those on the SXU and are therefore also separately described. The
SCU is only for operation with the NMG as a Simserver, and therefore requires the SOS
software to be installed for this to be used.
The
EWU
contains four GSM mobile engines and four SIM card readers for each GSM-
Channels. The front panel contains:
- One RF output to be connected to the ACU or to an appropriate antenna.
- One strain relief lug for the antenna cable.
The EWU contain four LEDs for each mobile engine and two LEDs for the EWU itself as
Status-Display. The SIM card reader GSM-Channel can be inserted by SIM cards of diffe-
rent providers (multiple provider mode) at the same time or can be left without SIM card.
Standard or prepaid SIM cards can be handled by the system at the same time.
The
ULU
is a Module that can supply 4 X U-Interfaces. On these interfaces endequipments
with U-Interfaces can be connected. In combination with PT-Repeaters and PT-US it is
then possible to operate end equipments with BRI Interfaces up to 24km away from the
actual system.
The ULU is also available with powered interfaces therefore end equipments i.e. the PT
can be powered over greater distances.
