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 200 extensions and 28 lines as well as some system features.
DSS40 handles the 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 then page 11 shows extensions 1111 to 1199, page 12 shows extensions 1200
to 1299 and page 13 shows extensions 1300 to 1310, at maximum capacity. It is
also possible to scroll forward and backward among the pages, via the “+” and “-“
keys on DSS40 keypad. The states of 28 lines as well as system features are
displayed on all pages.
The outlook and BDP of DSS40 are illustrated in the following figures.
