Modular ICS 7.1 Installer Guide
U-NT and U-LT loops can be used in combination to provide
D-packet service for a point-of-sale terminal adapter (POSTA)
or other D-packet device. D-packet service is a 16 kbps data
transmission service that uses the D-channel of an ISDN line.
To deliver D-packet service, a network connection (U-NT) is
programmed to work with a terminal connection (U-LT). The
loops must be on the same physical card. For example, if the
network connection is a loop found on the BRI Card in Slot 1,
the terminal connection must be a loop found on the same card.
S reference point
The S reference point connection provides either a point-to-
point or point-to-multipoint digital connection between
Norstar and ISDN terminal equipment (TE) that uses an
S interface.
S loops support up to seven ISDN DNs, which identify TE to
the ICS.
