The reference model for the ISDN-basic access according to CCITT I series recommendations
consists of
– an exchange and trunk line termination in the central office (ET, LT)
– a remote network termination in the user area (NT)
– a two-wire loop (U interface) between NT and LT
– a four-wire link (S interface) which connects subscriber terminals and the NT in the user

ISDN-Basic Subscriber Access Architecture
The NT equipment serves as a converter between the U interface at the exchange and the
S interface at the user premises. The NT may consist of either an NT1 only or an NT1 together
with an NT2 connected via the T interface which is physically identical to the S interface. The
NT1 is a direct transformation between layer 1 of S and layer 1 of U. NT2 may include higher
level functions like multiplexing and switching as in a PBX.
The ISAC-S TE is designed for the user area of the ISDN-basic access, especially for
subscriber terminal equipment with S interfaces. Figure 4 illustrates the application of the
ISAC-S TE.
