DSX-40 Common Equipment
DSX-40 4x8x2 Key Telephone System with 2 Door Box Ports and Caller-ID
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
con
fi
guration, 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.
