  Public Switched Telephone Network - Wikipedia, the free encyclopedia
The public switched telephone network (PSTN) is the concentration of the world's public circuit-switched telephone networks, in much the same way that the Internet is the concentration of the world's public IP-based packet-switched networks.
Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital, and now includes mobile as well as fixed telephones.
Although the network was created using analog voice connections through manual switchboards, automated telephone exchanges replaced most switchboards, and later digital switch technologies were used.

 RFC (Request for Comments) 3482   (Site not responding. Last check: 2007-10-11)
The donor network is the network that first assigned a telephone number (e.g., TN +1-202-533-1234) to a subscriber, out of a number range administratively (e.g., +1 202-533) assigned to it.
The old serving network (or old SP) is the network that previously served the ported number before the number was ported to the new serving network.
It is assumed that the old serving network, the new serving network, and the donor network are different networks so as to show which networks are involved in call handling and routing and database queries in each of the four schemes.

The telephone network is simple to use and provides bi-directional and multi-directional communication (for example in a conference call), in a fully random-access mode where any point is accessible to any other point.
The importance of the telephone network will continue to grow during this decade as communication speeds on the network improve, as the network becomes able to support a greater variety of media, and as it becomes cheaper to use.
This power of computers on the communication network will make the photocopier into the ‘quill pen’ of the 20th century, and is already creating a legal nightmare, [129], [130] The National Writers Union in the U.S. claims that electronic publishers are violating their copyrights and that they are losing tens of millions of dollars.

 RFC 3482 (rfc3482) - Number Portability in the Global Switched Telephone N
Since a TN can port a number of times, the old SP is not necessarily the same as the donor network, except for the first time the TN ports away, or when the TN ports back into the donor network and away again.
If an entity in the IP-based network needs to query those existing NPDBs for routing number information to terminate the calls to the destination GSTN, it would be an impractical, if not impossible, job for that entity to support all those interface standards to access the NPDBs in many countries.
NP certainly must be considered at the first level because the telephony service providers do not "own" or control the telephone numbers under the NP environment; therefore, they may not be the proper entities to have the authority for a given E.164 number.

 RFC 3601 (rfc3601) - Text String Notation for Dial Sequences and Global Sw
Network Working Group C. Allocchio Request for Comments: 3601 GARR-Italy Category: Standards Track September 2003 Text String Notation for Dial Sequences and Global Switched Telephone Network (GSTN) / E.164 Addresses Status of this Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements.
A Dial Sequence is normally composed of Dual Tone Multi Frequency (DTMF) elements, plus separators and additional "actions" (such as "wait for dialtone", "pause for N secs", etc.) which could be needed to successfully establish the connection with the target service: this includes the cases where subaddresses or DTMF menu navigation apply.
Although the commonly called "telephone numbers" are normally used to generate a Dial Sequence when establishing a connection, the full abstract E.164 addresses [2], i.e., the universal addressing on the Global Switched Telephone Network (GSTN), have further elements which cannot be dialled.
