1.3  Key terms used in this document 
Service Provider 
In this document, the term Service Provider (SP) refers to companies who provide 
telecommunications services as a business. SPs may operate networks, or if they do not operate 
networks they may simply integrate the services of other providers (who operate networks) in order to 
deliver a total service to their customers. In this document a Value-added Service Provider is also 
called a SP. 
Providing telecommunications service to any one End-Customer may involve multiple SPs, where 
one SP may "sub-contract" with other SPs to fulfill the customer's needs.  When necessary to 
account for this relationship, the term SP is used in this document to describe the enterprise 
responsible to provide service to an End-Customer: the SP provides access through a contract or 
subscription.  The term Other Provider is used to denote enterprises which have a sub-contractual 
responsibility.  
Network and Network Provider 
In this document, the term Network refers to the networks, networking components, network systems 
and/or network management systems which may or may not be owned and operated by the SPs 
which are used to deliver services.  
The network is managed by the Network Provider whose primary task is to organize the basic 
infrastructure, such as switches, interlinks, local loop etc. The services can be supplied internally 
within the same organization, to its own SP organization, or to external SPs.  
Note: The European Commission, in its Green Paper, has regulated that a formal split be made 
within telecoms in network operating departments and SP departments with a formal supplier 
relationship that is equal to an external vendor/buyer relationship. This relationship must be non-
discriminatory. Similarly, requirements of the FCC Ruling on Interconnection in the US are 
encouraging companies to formally separate their network provider and SP business. 
Equipment or Network Elements (NEs) 
Equipment or Network Elements (NEs) is the short term for the basic infrastructure, i.e. the hardware 
and software components of the network. The use of this term emphasizes the technological aspect 
of network elements and systems components. In the usual case, Equipment is vendor-specific to a 
large extent. For billing, this means that the raw accounting data is delivered often in a vendor-
specific format and reflects the functionality of the elements actually used. 
The Network Provider operates the equipment. In the conventional case where the SP and the 
Network Provider are identical, one may say that the SP has a direct interface to the equipment. 
Network Management System (NMS) 
The Network Management System represents the hardware and software components used by the 
SP or Network Provider to manage their networks as a whole. The NMS provides an end-to-end 
network view of the entire network enabling management of the NEs contained in the network. These 
NEs managed across the network are typically provided by multiple vendors. The NMS performs 
management functions across the Network Management Layer (NML) of the TMN. Some examples 
of these management functions include connection management and circuit fault correlation.  
Element Management System (EMS) 
The Element Management System  (EMS) represents the hardware and software components used 
by the SP or Network Provider to manage one or more Network Elements (NEs). The EMS provides 
management across a subnetwork or a single NE, typically across a single vendor equipment or 
collection of single vendor equipment. The EMS performs management functions across the Element 
Management Layer (EML) of the TMN. Some examples of these management functions include 
provisioning of NE resources and collection of NE faults.
