Relation between Parts

Radio Exchange

Item	Connects	Remarks
Modular Cabinet	9 System Boards	Number of System Boards may be less due to
	1 Connection Board	power limitations. Up to 4 cabinets can be chained.
		An MCCB is factory mounted.
	2 Power Supplies
CPU	PC, Printer, General Alarm, SMS	Only 1 per system (also with a multi–cabinet
	and PWT air interface	system).
	synchronization signals	CPU/SDB synchronization cables.
		Note: Sync Kit required for each CPU. FPGA
		must be installed.
SLU	8 calls	An SLU consists of an SPU part and a CLU part.
	8 Base Stations	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	Modular Cabinet Connection Board
	for Base Station power
	PC, Printer/SMS and General
	Alarm
SDB	1 input and 3 output PWT air	To be mounted on the bottom plate of the Modular
	interface synchronization	Cabinet.
