C CSMA/CD Carrier Sense Multiple Access/Collision Detection (CSMA/CD) are a set of rules determining how network devices respond when two devices attempt to use a data channel simultaneously (called a collision). Standard Ethernet networks use CSMA/CD to physically monitor the traffic on the line at participating stations. If no transmission is taking place at the time, the particular station can transmit. L LED Light Emitting Diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. LEDs are used as visual indicators in network elements. N NMS Network Management System (NMS) provides an integrated management of Element Management Systems (EMS) across an intelligent optical network. NMS collects and represents management data from geographically dispersed EMSs on to a centralized database. O OAM Operation Administration Maintenance (OAM) is a group of management functions that provide node or network the functionality of fault indication, performance monitoring, security management and diagnostic functions. It is a popular framework among service providers for their network management systems. P PCM Pulse Code Modulation (PCM) is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a digital (usually binary) code. PDH Plesiochronous Digital Hierarchy (PDH) is a technology used in telecommunications networks to transport large quantities of data over digital transport equipment such as fibre optic and microwave radio systems. It is the conventional multiplexing technology for network transmission systems.
