A network that has a synchronizing arrangement in which each clock in the network exerts a degree of control on all others.

A condition of an interface, as determined by the network, based on the network's capability to terminate another call to that interface. The interface is said to be NDUB if any of the following conditions exist: (a) if the maximum number of information channels available has been reached and the network does not support the offering of additional calls beyond… (Read More →)

1. An interconnection of three or more communicating entities.
2. An interconnection of usually passive electronic components that performs a specific function (which is usually limited in scope), e.g., to simulate a transmission line or to perform a mathematical function such as integration or differentiation.
Note: A network may be part of a larger circuit.

A physical entity that provides network access for users. It contains the call-control agent function and may include the call-control function. [T1.667-1999]

The signaling point code, containing for U. S. national networks, the network identification, network cluster, and network cluster member fields (24 bits). [T1.110-1987]

Wherever the carrier places the home router, they typically request the IP addresses in the home not be represented directly to the network. Instead, a transplant NAT is used.

A group of network management functions that (a) provide support services, (b) ensure that the network is used efficiently, and (c) ensure prescribed service-quality objectives are met.
Note: Network administration may include activities such as network address assignment, assignment of routing protocols and routing table configuration, and directory service configuration.

1. The design principles, physical configuration, functional organization, operational procedures, and data formats used as the bases for the design, construction, modification, and operation of a communications network.
2. The structure of an existing communications network, including the physical configuration, facilities, operational structure, operational procedures, and the data formats in use.

Network Attachment is the process by which a network entity (such as the ITF or DNG) establishes Layer 3 connectivity to an IP-network and obtains network configuration data.

The probability a network can perform its required functions. [T
