II.1.D. DSS40 DIRECT STATION SELECT MODULE
The DSS40 Direct Station Select Module, which is used as an add-on module for
OP48(-H) Consoles and LT48(-H) Feature Phones, consists of a BDP (Busy
Display Panel), a 2-Character Display and a programmable keypad including 40
multipurpose keys and 40 corresponding LEDs.
Each key may be programmed to activate two facilities, which may be calling an
extension, accessing a line or activating a system feature. The corresponding LED
of each key shows the status of the facility assigned to the primary function of the
key.
The BDP (Busy Display Panel) together with the 2-Character Display shows the
states of 124 extensions and 20 lines as well as some system features.
DSS40 can be used not only with the MS128 system, but also with the other
KAREL systems of bigger capacities. That is why DSS40 handles 4-digit physical
numbers for extensions, such that the 2-Character Display is used to show the
most significant two digits whereas the LEDs on the BDP are used to indicate the
least significant two digits. In this way, the two digits in the 2-Character Display may
be interpreted as “page numbers”, and there are 3 pages with numbers 11 to 13
that covers all the extensions in the KAREL systems to which DSS40 can be
connected. It is also possible to navigate forward and backward among the pages,
via the “+” and “-“ keys on DSS40 keypad. However, when DSS40 is connected to
MS128 system, it is enough to observe the first page (page 11) for the extensions
111 to 199 and the second page for the extensions 200 to 234. The states of 20
lines as well as system features are displayed on all pages.
The outlook and BDP of DSS40 are illustrated in the following figures.
