Which of the following does not come under subsystem of GSM architectu...
Explanation:

GSM (Global System for Mobile Communications) is a standard for mobile communication that is widely used around the world. It consists of various subsystems that work together to provide reliable and efficient mobile communication services.

The GSM architecture is divided into three main subsystems:

1. Base Station Subsystem (BSS):
The Base Station Subsystem (BSS) is responsible for handling the communication between mobile devices (MS) and the mobile network. It consists of two main components: the Base Transceiver Station (BTS) and the Base Station Controller (BSC). The BTS handles the radio transmission and reception, while the BSC controls and manages multiple BTSs.

2. Network Subsystem (NSS):
The Network Subsystem (NSS) is responsible for the core network functions of the GSM system. It includes the Mobile Switching Center (MSC), which is the main switching element that connects mobile devices to other networks such as the Public Switched Telephone Network (PSTN) and the Internet. The NSS also includes the Home Location Register (HLR) and the Visitor Location Register (VLR), which store and manage subscriber data and location information.

3. Operation and Support Subsystem (OSS):
The Operation and Support Subsystem (OSS) is responsible for the management and monitoring of the GSM network. It includes various components such as the Operation and Maintenance Center (OMC), which provides centralized control and monitoring of the network, and the Authentication Center (AUC), which handles the authentication and security functions.

4. Channel:
The channel is not a subsystem of the GSM architecture. In GSM, the channel refers to the frequency band that is used for communication between the mobile device and the base station. There are several types of channels in GSM, including the traffic channels used for voice and data transmission, as well as control channels used for signaling and control purposes.

Conclusion:
In conclusion, the correct answer is option D, "Channel," as it is not a subsystem of the GSM architecture. The other options, BSS, NSS, and OSS, are all important subsystems that play specific roles in the functioning of the GSM network.
