OfficeServ 100 General Description Guide/Ed.00

1.2 Size and Configuration

The OfficeServ 100 system consists of the basic KSU(Key Service Unit), an Expansion

cabinet, Interface cards and Digital keysets. The KSU begins with eight keyset ports

expandable to 18 analogue C.O. line ports, or 24 lines if 4 BRI cards are used, or 32

stations. In addition, up to 8 keyset daughter boards may be added to the system along with

the optional 2 SLI card.

The Expansion cabinet A type has three Universal slots and one DCS slot for TEPRI(PRI)

or SVMi-8, which provides the maximum configuration of 66 ports with analogue trunk

lines or 96 ports with Digital trunk lines.

The Expansion cabinet B type has two Universal slots and two DCS slot for TEPRI(PRI) or

SVMi-8, which provides the maximum configuration of 58 ports with analogue trunk lines

or 88 ports with Digital trunk lines.

Two types of telephones can be connected to the system: proprietary digital stations called

‘keysets’ that connect to DLI ports and standard telephone sets, generally called ‘Single

Line Telephones’, that connect to SLI ports.

The system also has an optional MISC card, which provides Music on Hold facilities, two

serial I/O ports and other useful facilities.

The following charts(Figures 1.2, 1.3, 1.4, 1.5) describe configurations using the basic

KSU, an Expansion cabinet and expansion cards. However, by using the DCS’s unique

KDB(Keyset Daughter Board), which are installed in the base of a digital keyset, the

capacity of the system can be increased by one station per KDB. Installing a KDB-DLI

adds another digital port while a KDB-SLI adds a single line port. Mix and match these

two types of KDB to get up to a total of 8 KDB in the system. Using this method allows the

OfficeServ 100 to expand to a maximum of 64 stations. Adding the optional 2 SLI card to

the KSU provides a further two SLI ports.

The combination of the basic 008 KSU plus three expansion cards in the KSU plus three

expansion cards and one DCS card in the Expansion cabinet plus 8 KDB plus a 2 SLI card

provides a maximum configuration of 96 ports plus Miscellaneous card.
