List of terms

NTP

See network time protocol (NTP) (page 88).

NTS

See Network Time Synchronization (NTS) System (page 89).

numbering-plan indicator (NPI)

The part of a given data network address that defines the numbering plan to which it belongs. Examples of numbering plans defined by ITU-T are X.121 and E.164.

OAM

See operations, administration, and maintenance (OAM) (page 93).

OC-3

Optical carrier level 3. In SONET networks, OC-3 is the optical form of the first SONET multiplexing level when it is transmitted through an optical fiber. The

155.52Mbit/s OC-3 signal is made up of three multiplexed OC-1 basic channels.

OC-12

An optical carrier signal in the SONET optical format that is 12 times the OC- 1 rate.

OC-48

A high-speed optical carrier signal in the SONET optical format providing a line rate of 2.488 Gbits/s, ATM services, and traffic management.

OC-N

Optical Carrier level N. The optical signal that results from an optical conversion of an STS-N signal.

off-network call

A call destined to another network. An off-network call crosses one or more gateways.

on-network call

A call that is routed internally through the SCR and DCR systems to a destination within the network.

open shortest path first (OSPF)

An IP routing model defined in RFC 1583, whereby the shortest route to a destination is calculated from a database of link states.
