BSC6000 can be upgraded to BSC6900 by software change only , but hardware change is also required if we want to increase the hardware capability and to
support new feature.
BSC6900 Subrack Types
Prepared by Mohyedeen Alkousy04/13/2023 5
MPS Subrack
TCS Subrack
EPSSubrack
The MPS performs centralized switching and provides traffic paths for other subracks. It also provides the service processing interface, OM interface, and system clock interface.
Extension subrack that provide the same services as main subrack , The EPS performs the functions of user plane processing and signaling control.
The TCS processes CS services by performing the functions of voice adaptation and code conversion

Mandatory Optional / expand according to the traffic needs
In this configuration mode the BM and TC cabinets areMerged into one cabinets that will perform all the functions thus provide maximum integration , but the transcoder in this case cannot be adopted remotely.

Mandatory Optional / expand according to the traffic needs
In this configuration mode the BSC doesn’t need TCS because the transcoding function will be performed by Huawei media gateway at the core side (MGW).

The BSC6900 supports two data configuration modes: • effective mode .• ineffective mode.
Effective modeIf data configuration is performed on the BSC6900 in effective mode, then the relevant configuration data takes effect on the host boards in real time.Ineffective modeIf data configuration is performed on the BSC6900 in ineffective mode, then the relevant configuration data takes effect only after the BSC6900 is reset or is switched to the effective mode.
Data Configuration Modes
