Relation between Parts
Radio Exchange
Item Connects Remarks
Modular Cabinet 9 System Boards
1 Connection Board
2 Power Supplies
Number of System Boards may be less due to
power limitations. Up to 4 cabinets can be chained.
An MCCB is factory mounted.
CPU PC, Printer, General Alarm, SMS
and PWT air interface
synchronization signals
Only 1 per system (also with a multi–cabinet
system).
CPU/SDB synchronization cables.
Note: Sync Kit required for each CPU. FPGA
must be installed.
SLU 8 calls
8 Base Stations
An SLU consists of an SPU part and a CLU part.
The SLU can be combined with SPU and CLU
boards.
The SPU part provides for 8 speech paths. The CLU
part can connect 8 Base Stations.
CLU/MDF Cables and CLU/MCCB Power cables.
Quantity depends on required traffic capacity and
GOS.
DTU-E1, CCS 60 simultaneous calls Two 2–Mbit links, each link having 30 channels to
which Portable Telephones are assigned
dynamically. The maximum number of Portable
Telephones depends on the GOS and the traffic
capacity of the RE configuration (1 per RE)
DTU-T1, CCS 46 simultaneous calls Two 1.544-Mbits, each link having 23 channels to
which Portable Telephones are assigned
dynamically. The maximum number of Portable
Telephones depends on the GOS and the traffic
capacity of the RE configuration (1 or 2 per RE).
DTU-E1, CAS 60 individual extensions Two 2–Mbit links, each link having 30 channels to
which Portable Telephones are assigned on a
dedicated basis. (Max. 10 per system)
DTU-T1, CAS 48 individual extensions Two 1.544-Mbits, each link having 24 channels to
which Portable Telephones are assigned on a
dedicated basis. (Max. 13 per system)
LTU 8 PBX lines (analog, 2 wires) LTU/MDF Cable Set- 1 cable supports 3 LTUs . A
maximum of 272 Portable Telephones supported.
DLU 12 PBX lines (1:1 digital lines) DLU/PBX Cable Set- 1 cable supports 2 DLUs. Each
DLU supports 12 Portable Telephones.
CLU 8 Base Stations – 2.2 miles CLU/MDF Cables and CLU/MCCB power cables.
CLU-S 8 Base Stations – 1.2 miles
SPU 8 calls The SPU provides 8 speech paths. Quantity
depends on required traffice and GOS.
MCCB 3+7 CLU or 3+7 SLU power ports
for Base Station power
PC, Printer/SMS and General
Alarm
Modular Cabinet Connection Board
SDB 1 input and 3 output PWT air
interface synchronization
connections
To be mounted on the bottom plate of the Modular
Cabinet.
