M2M	Machine-to-Machine - a broad label that can be used to describe any technology that enables networked devices to exchange information and perform actions without the manual assistance of humans. In Vodafone, M2M is being substituted by IoT (Internet of Things).
MSISDN	Mobile Station International Subscriber Directory Number - a number uniquely identifying a subscription in a GSM mobile network. It is the telephone number to the SIM card in a mobile or cellular phone. The MSISDN is an important number used for identifying a mobile subscriber. It is used for routing calls to the subscriber. MSISDN is the number normally dialled to connect a call to the mobile phone.
MSISDN (CSD)	The Secondary MSISDN - the telephone number in an international format used in data calls to and from the IoT device. Typically, these calls are Circuit Switched Data (CSD). CSD is a legacy connection-oriented low-speed data technology and is deprecated across much of the world. The secondary MSISDN is only required where the device is unable to recognize incoming voice as opposed to data calls and requires a separate line to do so.
MSISDN (Voice)	The Voice MSISDN - the telephone number in an international format used in telephone calls to and from the IoT device using the SIM. Voice services are secondary to IoT data services and are only available where specifically enabled. The MSISDN is also used for certain messaging services.
NB-IoT	Narrowband Internet of Things - a Low Power Wide Area Network (LPWAN) radio technology standard.

Voice (CS)	Voice (Circuit Switched) - the traditional voice telephone call service provided by mobile and fixed telephone networks. These services are circuit switched because an individual radio link and call connection is established for the duration of the call. Modern voice telephone services now use packet switched transmission technologies, such as Voice over IP.
VPN Group	Voice Private Network Group - the VPN group defines a closed voice calling capability to and from IoT connections. The IoT service does not provide open public telephone calling. Instead, VPN Groups record the permitted inbound and outbound telephone numbers that may call and/or receive calls with IoT connections.
Wake-up notification URL	The wake-up notification URL specifies the address of an API on a customer server. When enabled and configured, the Vodafone IoT service makes an outbound API call to the URL to inform the customer server whenever an IoT device wakes and establishes a data connection in the PDP context over the cellular network.
