The base station then connects the call to the MSC. The MSC then connects the call to the destination phone, which may be a mobile phone or a landline phone.<\/p>\n<p>The MSC also handles call routing and handover. Call routing is the process of directing a call to the correct destination. Handover is the process of transferring a call from one base station to another as the mobile phone moves around.<\/p>\n<p>The MSC is a critical part of the cellular network. It is responsible for ensuring that all calls are connected and that the network is operating efficiently.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: Connection of mobile to base stations. This is the correct answer. The MSC is responsible for connecting mobile phones to the base stations in its area of coverage.<\/li>\n<li>Option B: Connection of mobile to PSTN. This is not the correct answer. The MSC is responsible for connecting mobile phones to the base stations in its area of coverage, not the PSTN.<\/li>\n<li>Option C: Connection of base station to PSTN. This is not the correct answer. The base station is responsible for connecting mobile phones to the MSC, not the PSTN.<\/li>\n<li>Option D: Connection of base station to MSC. This is not the correct answer. The base station is responsible for connecting mobile phones to the MSC, not the other way around.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on
