10.1.1 CONNECTIONS WITH THE PBX
The radio base station connector is a female RJ45 connector.
The connection to the PBX main distribution frame uses 3 pairs (two pairs for the S0 part
and one pair for clock synchronization).
Note: You are recommended to use RJ45 connectors to facilitate maintenance of the
radio base station.
The pinout is S0 type:
Pin
Signal
The wiring on the radio base station side uses a 3-pair cable.
The pinout is of S0 type, plus one synchronization pair.
Pin
SYNC+
Signal
To synchronize the radio base stations to the same PBX:
♦
pin 1 in all radio base stations should be connected together
♦
pin 2 in all radio base stations should be connected together or directed through a
synchronization repeater (if more than five radio base station are installed)
The RSx pair receives S0 signals from the PBX.
The ESx pair sends S0 signals to the PBX.
The cable used to connect a radio base station to a wall mounted S0 connector must
comply with the standards in force:
♦
4-pair cable
♦
connection: pin 1 to pin 1; pin 2 to pin 2; ....; pin 8 to pin 8
Using the MMCs, configure each radio base station as master or slave depending on
whether it sends or receives the clock signal. There are two cases:
♦
MASTER mode - this clock is provided by the master radio base station and
transmitted to other radio base stations by the synchronization pair on the S0 link
♦
SLAVE mode - this clock is extracted from the synchronization pair on the S0 link
