DATASET 1101 Cartridge Description
14.4 A DATASET 1101 is mounted within a SUPE/%SE7 3DN or a SUPERSET 4DN
telephone. It is 13 x 13 cm (5 x 5 inch) and connects via an internal cable to the
telephone set circuit board; it interfaces to the PABX DNI Line Card through the same
pair of wires that the telephone set voice circuit uses. Although the DATASET I 101
Cartridge has LEDs near its connectors, its primary interface to the user is through
two programmable line appearance keys and an associated LCD on the telephone
set. Figure 14-I shows a DATASET II 01 Cartridge mounted in a set; note that in this
example two keys and an LCD immediately above the prime line key of the set are
assigned to control operation of the DATASET II 01 Cartridge. These are
programmed in Form 9 during Customer Data Entry.
The DATASET 1101 Cartridge usually interfaces a terminal, a personal computer, a
printer, a file disk, or another peripheral device to the PABX, for connection to a host
computer or to another peripheral device. Figure 14-2 shows a typical application of
a SUPE/?SE7 3DN set with a DATASET II 01 Cartridge connecting a personal
computer and the telephone set to the PABX over a single pair of wires.
The DATASin 1101 Cartridge is not field replaceable; it is an integral part of the
SUPERSET3DN
or
SUPERSET
4DN telephone.
