Configuration Type B

• Standard multi standard mixed mode

• N number ofDUS41 card will extend their GPS out

synchronization signal to N number of DUG cards serving for

DCS. (N=1 or 2, in this project)

• GSM can be available on not and that will only be a

dependency for the number of MUs going to be added

• DUS41/s could be install in the same MU or in separate MUs

where DUGs are installed which are serving for DCS

• There could be more than one RRUS [Two] per sector and one

of them could be DCS only.

Configuration Type C

• Extended multi standard mixed mode

• N number ofDUS31 card will extend their GPS out

synchronization signal to M (>N) number of DUG cards serving

for DCS. (N=1 or 2, in this project)

• GSM can be available or not and that will only be a

dependency for the number of MUs going to be added

• DUS31/s could be install in the same MU or in separate MUs

where DUGs are installed which are serving for DCS

• There could be more than one RRUS [Two] per sector and one

of them could be DCS only.

• The IDL2 port support would be available after Q2 2014.
