Lucent Technologies Inc.
Application Overview
The T7256 is intended for use in ISDN networks as part of a 2-wire to 4-wire converter (NT1) or as part of a termi-
nal adapter (TA), providing 2-wire termination of the network with available voice and/or data ports. Local switching
of terminal voice/data is also supported by the T7256. Figure 3 shows the NT1 and TA applications. See Using the
T7256 in a Combination TE/TA Environment in the Application Briefs section for a detailed explanation of an appli-
cation that has both TE and TA functions.
