1-1 Chapter 1 System Overview Introduction DCS-408 Digital Communication System is a digital telephone system designed for a small -sized business. The system employs the very latest Digital Signal Processors (DSP) technology. DCS-408 is easy to install and maintain, convenient to use and provides a variety of features.
1-2 Chapter 1 System Overview Size and configuration 408 Base KSU The DCS-408 system consists of the Basic Key Service Unit (KSU), 4 analog trunk circuits and 8 station circuits. The KSU is a single cabinet, and in its basic form has 4 trunks ports and 8 station ports: four (4) analog trunk circuits, four (4) keyset ports and four (4) single line telephone (SLT) ports. Additionally, the KSU contains two miscellaneous ports for general-purpose dry contact and external music source.
1-3 Programming DCS-408 is self-configuring. This means that when the power is switched ON, the system reads the types and locations of all installed cards and telephones and assigns default data to them. This data provides for system operation within seconds after power is switched ON. All trunks and stations are assigned according to the default numbering plan. This numbering plan is flexible and may be changed to suit customer requirements.
