DTE Access to Public Services and Networks

Abstract

The concept of DTE access involves all means and methods of communication between a DTE and the network by which the considered PDN service is provided. The data transmission service can be either of the switched or the leased circuit type. The network, if public, can be a CSPDN, PSPDN or ISDN. Contrary to the common use of the term, access here covers both directions of communication set-up, outgoing as well as incoming (the same applies of course to the directions of transmission). Access can be achieved:

• By direct connection of the DTE to the PDN or ISDN

• By switched connection of the DTE to a PDN or ISDN via an intermediate network of another type (including PDN, PSTN, Telex and ISDN with or without a terminal adaptor, see Chapter 2)
