Mobius TAS Glossary


TDM, or Time Division Multiplexing, transmits multiple signals or data streams over a single communication channel by dividing it into distinct time slots. Each signal takes turns utilizing the channel for transmission, enabling efficient and simultaneous communication between multiple devices or users.


The Public Switched Telephone Network (PSTN) refers to the global network infrastructure that enables the transmission of traditional telephone calls through a circuit-switched system. It is a collection of interconnected telephone lines, switches, and other equipment operated by various telecommunications providers worldwide. The PSTN allows users to make voice calls over long distances using analog or digital signals, providing reliable and widespread communication services.

IP Multimedia Subsystem (IMS)

IP Multimedia Subsystem (IMS) is a framework used in telecommunications to enable the delivery of multimedia services over IP networks. It provides a standardized architecture for integrating various communication services, such as voice, video, and messaging, into a single network infrastructure. IMS allows for the seamless convergence of different communication technologies, improving interoperability and enabling the creation of innovative multimedia applications.

Call Session Control Function (CSCF)

The Call Session Control Function (CSCF) is a key component in an IP Multimedia Subsystem (IMS) network that provides call control and session management functions for multimedia sessions, such as voice, video, and messaging. It acts as the signaling gateway between the access and core networks, processing and routing SIP (Session Initiation Protocol) messages between the user equipment and the IMS core.

Network Functions Virtualization (NFV) deployment

Network Functions Virtualization (NFV) deployment is a technology that replaces traditional, specialized network hardware with software-based virtualized functions running on standard servers. NFV enables flexible and scalable network infrastructure by virtualizing and abstracting network functions, such as firewalls, routers, and load balancers, allowing them to be dynamically deployed, managed, and scaled based on the network’s needs.
