Configuration Directions, Relation between Parts
Remarks
Number of System Boards may be less due to
power limitations. Up to 4 cabinets can be chained.
An MCCB is factory mounted.
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.
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.
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)
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).
Two 2–Mbit links, each link having 30 channels to
which Portable Telephones are assigned on a
dedicated basis. (Max. 10 per system)
Two 1.544-Mbits, each link having 24 channels to
which Portable Telephones are assigned on a
dedicated basis. (Max. 13 per system)
LTU/MDF Cable Set- 1 cable supports 3 LTUs . A
maximum of 272 Portable Telephones supported.
DLU/PBX Cable Set- 1 cable supports 2 DLUs. Each
DLU supports 12 Portable Telephones.
CLU/MDF Cables and CLU/MCCB power cables.
The SPU provides 8 speech paths. Quantity
depends on required traffice and GOS.
Modular Cabinet Connection Board
To be mounted on the bottom plate of the Modular
Cabinet.
