Telephone Number Standards

This document describes the Signalling System Number 7 (SS7) network capabilities forcompleting calls to end users with portable numbers. The SS7 network capability, known as Call Completion to a Portable Number (CCPN), provides the core functionality. CCPN also includes optional...

Purpose and Scope This document specifies guidelines for the administration and assignment of thousands-blocks (NXX-Xs) to Local Number Portability (LNP)-capable service providers (SPs) in rate centers where thousands-block number pooling has been ordered or implemented.1 All...

This kappa number standard applies to many kinds of chemical, semi-chemical, unbleached and semibleached pulps within the kappa number range 1 to 100. Above a kappa number of 100, precision of the test may decrease, and the relationship between kappa number and lignin...

Developed from the author's popular graduate-level course, Computational Number Theory presents a complete treatment of number-theoretic algorithms. Avoiding advanced algebra, this self-contained text is designed for advanced undergraduate and beginning graduate students in...

Use/relationship: The Document Number Assignment Report provides the information necessary to maintain the Government's document number usage records. This provides information on allocated document numbers for engineering design data documents comprising the elements of a TDP...

This method provides for the determination of the relative "hardness" or bleachability of chemical pulps (1) having a permanganate number below 35. This Useful Method covers two variations in a single procedure. One procedure is for low lignin content pulps having a permanganate...

This guide recommends minimum performance requirements for enhanced access to public safety services using the North American standard emergency telephone number, 9-1-1. This guide provides assistance to states, counties, and local jurisdictions in the development of 9-1-1 enhanced...

SCOPE AND OVERVIEW This technical requirements document defines the switch requirements for Number Portability (NP) between wireline networks, using the Location Routing Number (LRN) Method. The terms Number Portability (NP) and Local Number Portability (LNP) are used...

This is a rapid procedure for estimating mercaptan sulfur in naphtha or other low-boiling petroleum distillates. Copper number is defined as the number of milligrams of copper required to titrate 100 mL of sample. Mercaptan sulfur is calculated from the copper number. Hydrogen...

This memo defines serial number arithmetic, as used in the Domain Name System. The DNS has long relied upon serial number arithmetic, a concept which has never really been defined, certainly not in an IETF document, though which has been widely understood. This memo supplies the...

Bringing the material up to date to reflect modern applications, Algebraic Number Theory, Second Edition has been completely rewritten and reorganized to incorporate a new style, methodology, and presentation. This edition focuses on integral domains, ideals, and unique factorization in the...
