DSX-40 Common Equipment DSX-40 Common Equipment DSX-40 4x8x2 Key Telephone System with 2 Door Box Ports and Caller-ID At a Glance P/N 1090001 Digital extension ports: Built-in: 8 Fully expanded: 24 Analog extension ports: Built-in: 2 Fully expanded: 18 Built-in door box ports: 2 Built-in door box control relays: 2 Total Ports: 40 Ethernet port: Yes (auto sensing) Analog line ports: Built-in: 4 Total: 8 Expansion slots: Station expansion slots: 2 Line expansion slots:1 Audio outputs: 1 Audio inputs: 2 CompactFlash interface: Yes USB connector: Yes DSX-40 is a compact, wall-mountable, more economical member of the DSX family that offers many of the features and options of the larger DSX-80/160 in a smaller, self-contained cabinet. In its off-the-shelf basic configuration, DSX-40 supports 4 CO (outside) lines with Caller ID, 8 DSX digital keyset extensions, and 2 analog (single line) extensions with power failure. Additionally, the basic DSX-40 provides: • CompactFlash card interface (for IntraMail, software loading, and database backup) • Conference circuits, DTMF receivers and DTMF generators • NAND Flash for storing the system database • Battery for short term (14 day) backup of the internal Real Time Clock and station parameters • Two audio inputs for Background Music and Music on Hold (1/8" mono minijacks) • One audio output for External Paging (1/8" mono minijack) • Ethernet and USB ports for local and remote PC Programming • RS-232 serial port for Station Message Detail Recording • 2 DSX Analog Door Box ports with associated relays • Built-in V.32BIS 14.4K BPS modem for remote maintenance Tips to remember: 1. The CPU also has a reset switch that provides the following three functions: • System reset (when momentarily pressed). • System initialization (when held down as power is turned on). • Software update (when held down for a few seconds while a software update CompactFlash card is installed). 2. DSX-40 provides FSK Message Waiting. It does not provide high voltage Message Waiting. Even with all the value built into the basic off-the-shelf DSX-40, the system is easily expandable by adding station and line PCBs. See DSX-40 PCBs (page 13) for more. 12 ◆ Components DSX-40 Hardware Manual
