Function
Subrack
Num
Function
MPR
1
MPR includes 1 main processing subrack (MPS) and
0, 1 or 2 extended processing subracks (EPSs)
MPS
1
MPS provides centralized O&M, system clock, service
processing and inter–subrack connections.
EPR
0-1
1 to 3 EPSs can be configured
EPS
0-5
EPS performs service processing.
Notes
This cabinet is not identical to that of the BSC6900
(differences include power distribution unit + cooling)
Notes
This subrack is not compatible with that of BSC6900.
Higher power consumption required change of air flow within
cabinet (mechanical changes).

Subsystems:
BSC6910 Logical Structure
Switching Subsystem
The switching subsystem performs switching of traffic data,
signaling, and O&M signals of the BSC6910.
Service Processing Subsystem
The service processing subsystem processes BSC6910 services and performs
controller functions defined in 3GPP specifications.
Interface Processing Subsystem
The interface processing subsystem provides transmission ports and resources
for the BSC6910, processes transport-layer and network-layer messages,
and enables interaction between BSC6910 internal and external data.
Clock Synchronization Subsystem
The clock synchronization subsystem of the BSC6910 consists of the
Clock board and the clock processing units of each subrack. It provides working
clocks and reference clocks for base stations for the BSC6910.
O&M Subsystem
The O&M subsystem enables management and maintenance in the following
scenarios: routine maintenance, emergency maintenance, upgrades, and capacity
expansion. It enables management in data configuration, security, performance,
alarm, loading, and upgrade.

BSC6910
Subrack interconnection
(SCUc)
The SCUc in a subrack provides four 40GE ports for intersubrack connection.
There is a connection between every two adjacent
nodes.
If an intermediate node is out of service, the
communication between other nodes is affected. If
three or fewer subracks are configured, they are
connected in a star topology.
The MPS and two EPSs in the MPR are connected in a
star topology. In the star topology, the MPS functions as
the basic subrack and the EPSs function as extension
subracks. The EPSs in the MPR and the EPSs in the EPR
are connected in a chain topology. Figure 2 shows the
star and chain topologies.
