INTRODUCTION

2.1
The GDK-100 Digital Key Telephone System is a fully digital hybrid Key Telephone System, designed to
meet the telecommunication needs of medium sized business offices.
The GDK-100 System incorporates state of the art digital technology for command processing and voice
switching, utilizing a Pulse Code Modulation/Time Division Multiplexing (PCM/TDM, "A" law) distributed
switching matrix.
The GDK-100 achieves a high level of flexibility by 1) employing a Universal Card Slot architecture with
a Small Basic, Basic and Expansion cabinet to house plug-in Printed Circuit Boards, and 2) providing
support for different types of instrumentation.
The GDK-100 Small Basic, Basic and Expansion KSU are wall mounted cabinets that house the back
plane and contain card slots for the system power supplies, CO line /Key Station /SLT /ISDN /DECT
interface boards, and other optional PCBs. Station, CO Line, SLT, ISDN, DECT and optional boards are
installed in any of the system card slots up to the system's maximum configuration. MISB can be installed
only slot 8 of Basic KSU, Digital Line Boards (E1IB, PRIB, BRIB, STIB) and WTIB can be installed from
slot 1 to slot 7 of Basic KSU, and DVIB(Digital Voice Interface Board) can be installed from slot 1 to slot 7
of Basic KSU. Thus, the system capacity is established by the number of cabinets and the types of
interface boards installed and is not limited by an artificially fixed Station to CO Line ratio.
The system architecture has been designed to allow a high level of software control over the system's
hardware. The software incorporates a vast array of features and capabilities including PC Database
Administration, Auto Route Select, ACD, etc.
The GDK-100 system supports a combination of Digital Keysets (KD, KD/E, KD/S, KD/C, LKD series),
Electronic Keysets(GSX, GSX/E series), various kinds of ISDN terminals, and wireless terminals as well
as analogue single line devices. With the keysets, commonly used features are activated by direct button
selection. Additionally, many functions may be accessed by dialing specific codes or optionally, by
assigning these dial codes to Flexible Buttons on the keyset. In addition to key telephones, an array of
optional terminals is available including DSS/DLS Console, Intercom/Door Box.
With the flexibility of the GDK-100 extensive feature content, and the capability to use an array of
instruments, the GDK-100 can be tailored to meet the short and long term needs of the most demanding
customer requirements.
