E
communication link. It carries control signaling from the MP to device boards
in the subracks.
Gamma Cable
The gamma cable connects the BBIFB and RFIFB. The BBIFB and RFIFB can
connect two gamma cables, one for each antenna branch. It carries serial
traffic streams from the gamma interface.
Intra-Cabinet Timing Cable
The intra-cabinet timing cable is a connection between the BBIFB and RFIFB.
This cable connection distributes timing signals from the RF subrack to the
baseband subrack and to read RFIFB product information.
Inter-Subrack Timing Cable
The inter-subrack timing cable distributes timing signals from the TUB to RF
subracks. The cable is connected to the BBIFB in the main baseband subrack
and to all RFIFBs. In a multi-cabinet configuration these cables must be
of same length.
Internal Jumper Cable
The internal jumper cable connects an AIU to the connection field at the top of
the RBS cabinet. As an AIU can handle two antenna branches, two cables are
connected per AIU. The cable carries the transmit RF and receive RF signals.
For mast mounted equipment, the AIU can feed power through both cable
connections. One of the antenna connectors also has the capability to carry
the auxiliary unit interface, which supervises and controls units, for example
the ASC.
MCPA and MCPA Fan Unit Control Cable
The MCPA and MCPA fan unit control cable is the auxiliary unit control
connection for the MCPA and MCPA fan unit. The cable is connected between
RFIFB and MCPA connector hub. MCPAs within the MCPA subrack and the fan
unit are controlled through the same the connection.
Low-Power Multi-Carrier TX Cable
The low-power multi-carrier TX cable carries the low power RF signal after
carrier combination and signal splitting (if applicable) from the AIU to the MCPA.
High-Power TX Cable
The high-power TX cable carries the RF signal from the MCPA to the AIU after
power amplification.
Site LAN Cable
The site LAN cable is an Ethernet based connection for the thin client. The
site LAN cable connects the Ethernet interface of the MP to the connection
field at the top of the RBS cabinet.
