1-1. OFFICE STE AND TACTICAL STE DESK SETS
The STE desk set, shown in Figure 1-2 , is made up of two parts: the STE and the Wedge.
1. The STE contains ISDN (Integrated Services Digital Network) and data processing circuits
common to all STE configurations.
2. The Wedge contains additional circuits that provide access to other telecommunications systems
as described below.
The Office Desk Set is available in two configurations: ISDN only, and ISDN and PSTN (Public Switched
Telephone Network). When equipped with a standard wedge, access is available only to ISDN for voice
and data operation. When equipped with a PSTN wedge, access is available to both ISDN and PSTN for
voice and data operation. The Wedge can contain either a Conventional PSTN Adapter or an
International PSTN Adapter. Conventional PSTN STEs can be used in the United Stated or in other
countries where they are approved for use. The International PSTN STEs can be used worldwide. The
default setting for the International adapter is “United States”. Actions required to prepare the
International Adapter for in other countries is addressed in Chapter 2. The Office STE operates under
local control (dial pad) for voice and data operation and under remote control, via a connected Personal
Computer (PC), for data operations.
