4.7.2 Gamma Cable
This cable connects the BBIFB and RFIFB. The cable carries serial traffic
streams from the gamma interface. The BBIFB and RFIFB can connect two
gamma cables, one for each antenna branch.
4.7.3 Intra-Cabinet Timing Cable
This cable is also a connection between the BBIFB and RFIFB. This cable
connection distributes timing signals from the RF to the BB subrack and is used
to read RFIFB product information.
4.7.4 Inter-Subrack Timing Cable
This cable distributes timing signals from the TUB to RF subracks. This cable
is connected to the BBIFB in the main BB subrack and to all RFIFBs. In a
multi-cabinet configuration these cables must have the same length.
4.7.5 Internal Jumper Cable
This cable carries the transmit and receive RF signals.
The cable connects an AIU to the Connection Field, and since an AIU can
handle two antenna branches, two cables are connected per AIU. For Antenna
Near Products, the AIU can feed power through both cable connections. One of
the antenna connectors also has the capability to carry the AU interface, which
supervises and controls units, for example the ASC.
4.7.6 MCPA and MCPA Fan Unit Control Cable
This cable is the AU control connection for the MCPA and MCPA fan unit. This
cable is connected between RFIFB and MCPA hub. MCPAs within the MCPA
subrack and the fan unit are controlled through the same connection.
4.7.7 Low-Power Multi-Carrier TX Cable
This cable carries the low power RF signal after carrier combination and signal
splitting (if applicable) from the AIU to the MCPA.
4.7.8 High-Power TX Cable
This cable carries the RF signal from the MCPA to the AIU after power
amplification.
4.7.9 Site LAN Cable
This cable is an Ethernet-based connection for the thin client. The site LAN
cable connects the Ethernet interface of the GPB to the Connection Field.
4.7.10 Transmission Cable
This cable connects the ETB to the Connection Field.
