Digital Keysets
The DCS-408/DCS-408i system provides four ports, DLI1–DLI4, for digital keysets. Connect
the digital keyset to one of the DLI ports using a pair of cables such as #24 AWG (0.5mm) or
#26 AWG (0.4mm).
Analogue Telephones
The DCS-408/DCS-408i system provides four ports, SLI1–SLI4, for analogue telephones.
Connect an analogue telephone to one of the SLI ports using a pair of cables such as #24
AWG (0.5mm) or #26 AWG (0.4mm).
System Options
The DCS-408/DCS-408i digital keyphone system includes several kinds of optional hardware
for memory backup selection, music source selection, etc.
Memory Backup Selection
The system is provided with a memory backup circuit (with a MEM BACK-UP switch) em-
ploying 256K memory and a super-capacitor in case of power failure. The MEM BACK-UP
switch is located on the upper right-hand side of the unit and is set to OFF by default.
When you have finished programming your system (using MMCs as described in the Sam-
sung Combined Programming Manual), turn the MEM BACK-UP switch to ON. If the switch
is not turned ON, all programmed data will be deleted if a power failure occurs.
