What are MSISDN and MSN? Easy-to-understand explanation of the basic concepts of the telecommunications industry
In the vast realm of the telecommunications industry, a multitude of technical terms and acronyms are used daily. Two common terms you may come across are MSISDN and MSN. Let’s dive into what these terms mean and how they are used in the telecommunications world.
MSISDN
MSISDN stands for Mobile Station International Subscriber Directory Number. It is a globally unique number that identifies a specific mobile device in a mobile network. In simpler terms, it is your mobile phone number. The MSISDN consists of a country code, mobile network code, mobile subscriber number, and possibly other codes, depending on the specific numbering plan used in a country.
With the MSISDN, operators and network providers can route voice calls, text messages, and data to the correct mobile device. It acts as a way to address and communicate with mobile devices within a cellular network. For example, when you make a phone call to a friend, your MSISDN is used to route the call to your friend’s mobile number.
MSN
MSN, on the other hand, stands for Multiple Subscriber Number. It is a term primarily used in the context of landline telephony, referring to the additional phone numbers associated with the main phone line. These additional phone numbers are commonly used in businesses where multiple lines are required for different departments or services but share a single physical connection with the public telephone network.
With the MSN feature, businesses can assign different phone numbers to various devices or users, all connected to the same physical line. For example, a company may have a main phone number for inquiries but also separate numbers for sales, customer support, and accounting. The use of MSN enables efficient call routing and helps ensure that calls are directed to the appropriate department or individual.
In summary, MSISDN is the unique mobile phone number used to address and communicate with mobile devices in a cellular network, while MSN refers to additional phone numbers associated with a main landline phone line, commonly used in businesses for call routing purposes.
Understanding these basic concepts of the telecommunications industry can help shed light on the technical aspects behind the devices and services we use daily.
