NovaTec
Mobile Gateway S20
4.5 Internal Structure of the NovaTec
Mobile
Gateway S20
The NovaTecMobile Gateway S20 is comprised of several different modules.All modules can
be inserted into the 19“ rack and then connected together at the rear of the rack via the
backplane. The individual slots inside the system are clearly numbered on the backplane to
ensure easy identification. The left slot is Slot 1 where only the CCU should be inserted. On the
right, next to the CCU is Slot 2, and so on up to Slot 17. On the right-hand side of Slot 17 is
the power supply slot. This slot is double the width of the others and accommodates the power
supply for the whole rack. The slot designations (slot numbers) can be found on the front side
of the back plane. The numbers can be seen on the back plane when viewed from the insertion
side of the 19“ rack.
The CCU is a Central Control Unit and is the core of the system. The CCU provides four
BRA interfaces, one Centronics and one RS232 interface. In addition the CCU provides a
plug in space for either a four time BRA or a two time PRA expansion board.
The CCU Light corresponds to the CCU with the exception that the CCU Light has no BRI
Interfaces.
The CCU-3 corresponds in the basic functions to the CCU. The difference is firstly that
the CCU-3 has instead of the printer interface an ethernet interface, which can be either
operated with 10MBit or 100Mbit. Also the CCU-3 does not have ISDN Interfaces on the
board but can be equipped with either 2 PRI or 2 BRI boards. All Support-Functions, that
are on the CCU-Light/CCU via V.24 or ISDN are still realisable and can be carried out via
Ethernet on the CCU-3.
The Call-Back-Server (CBS) corresponds in the optical features the same as the CCU-3.
When the system is being used with the Call-Back-Functionality, the corresponding required
software CBS must be used. Installation guides for the CBS can be found in Chapter 5 of
this handbook under CBS.
The Sea-Of-Sims (SOS) must be used in conjunction with the Sim-Server . The SOS
corresponds in the optical features the same as the CCU 3. Operation of the NMG as Sim-
Server requires the installation of the SOS software and one SCU must be installed in the
system. Installation guides for the SOS can be found in Chapter 5 of this handbook under
SOS.
The WirelessAccess Unit (WAU) provides the access to the mobile network and contains:
- up to two daugther boards with two dual band engines each
- one 4 to 1 antenna combiner/multiplexer
- the electronic access to the backplane (hot plugable)
Please note: Never run the system without antenna! Do not leave any RF input without
termination!
Each daughter board contains the SIM card reader, which is accessible via the front panel.

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.
TheAntenna Combiner Unit (ACU) gathers the output of the WAU cards to one RF output.
This RF output shall be connected to the nextACU input or directly to the outdoor antenna
(the number of the possible cascade stages is location pendant. For more information please
contact NovaTec). TheACU 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 alsoseparately 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.

The PTI is a Module that can convert a BRI Interface to a U Interface. This would for
example be required when a row of ISDN end equipments in a Star formation are terminated
to a single point.
The following could be one solution: The PTI-SU in combination with the PT-US would
be operated, If at the location no power supply socket was available the use of the PTI-
SU-LP and the PT-US-LP would enable the power supply to be available to the equipment
at greater distances.
The DC4 is a power supply module. When Bri Interfaces are required for example for the
use of ISDN telephones and these ISDN telephones require power supply over the BRI
interface then a DC4 must be used within the system. For calculation purposes 8 X ISDN
telephones with typically 2 watts each require the use of 1 X DC4.
The B-Channel-Unit (BCU) enables the connection of the system to one or more IP Network
for using VOIP-Applications. This then gives the possibility to re-route Data or Speech
that is received into the system via ISDN, GSM or IP to other already existing IP networks.
The BCU is available as either a 4 Channel, 8 channel, 16 channel or 32 channel BCU. The
Modules are not destinguishable from each other from a front. If the BCU is removed from
the System a sticker can be found on the connectors on the Backplane with the Model
number, hereby the individual variants of the BCU can be differentiated. Each BCU can be
populared with a GPS receiver doughter board. This doughterboard is optional necessary
to be used minimum one in a system, when the NovaTec S20 has no other Synchronisation
Source and synchron data should be transfered via IP network (TDM over IP).
The Plug-in cards are sub Modules that can be attached to various mainboard Modules.
The Modules that can be equipped with Plug-in cards are the CCU, CCU-3 and CAU.
The following Plug-in cards are available at this time:
BRI-Plug-in card
The BRI-Plug-in card makes 4 additional BRAinterfaces available.With the BRAPlug-in
cards there are two different variants .The BRI Plug-in card with the article number
1F5021-2 only allows ISDN terminals to be attached. To the BRI Plug-in card with the
article number 1F5020-2 ISDN terminals or ISDN local loops can be attached alternatively.
The function of the proposed interface must be defined in the configuration.
PRI-Plug-in card
The PRI Plug-in card is likewise in two different variants available:
The PRI Plug-in card with the article number 1F5020-1 makes two S2M-Interfaces
available. On the other hand the PRI Plug-in card with the article number 1F5020-1/1
makes available only one S2M-Interface.
PRI-Plug-in card (with optional Echo Cancelation)
The PRI (ISDN 30) Module is available in 6 Variants:

These S2M (PRI ISDN 30) Add-on boards can be installed on the CCU3, CCU_Light and
the CAU.
1F5100R -> S2M-Add-on board with 2 PRI (ISDN 30) Interfaces with switch through for
the 1st S2M interface to the 2nd when system is inactive.
The Add-on board with the numbers 1F5100, 1F5100/1 and 1F5100R have no
echocancelling functions.
The Add-on board with the numbers 1F5100/1E 1F5100E and 1F5100R have
echocancelling functions on channel 1 (Recognisable by an „E“ in theArticle number).
TheAdd-on board with the numbers 1F5100ER and 1F5100R switch between Interface 1
to Interface 2 when the system is inactive, this allows for operated systems behind the
NovaTec to carry on operating when the NovaTec is out of operation.
GSM-2 Plug-in-card
The GSM-2-plug in card can be used on the WAU. It supports the system with two GSM-
Dual-Band interfaced with DTMF.
GPS-Receiver
The GPS-Receiver is an plug-in card only for the BCU. it supports the system with an
reference clock if no other reference clock source is available. In this case the system
needs minimum one receiver on one BCU.
SIM-Reader Plug-in card
The SIM-Reader Plugin-in card is an Sub-Modul only for the EWU. It supplies the EWU
with 16 Sim-Card-Reader ( 4 for each GSM-Channel of the EWU) and will be needed, for
lokal SIM-Cards. For Applications with SIMs in SIM-Server only the SIM-Reader Plug-
in card is not neccessary.
