DK40 Configuration
This chapter explains how to configure a Strata DK40 system. It also provides space to record
the hardware and station devices that make up the system.

Base Key Service Unit (KSU)

Station and Exchange Lines

The DK40 Base KSU can have up to eight digital telephone stations and four exchange lines
(Table 1-1). Instead of the exchange line PCB (TCOU), a two circuit ISDN BRI PCB (TBSU)
can be installed providing up to four B-channels set to NT or TE. An optional KSTU PCB
can be added to the Base KSU to provide four standard telephone circuits (ports).
Note

Peripherals

The DK40 Base KSU can support a number of peripherals, which are not considered as
stations and do not affect the maximum station and exchange line capacities. The DK40 Base
KSU can interface with an amplifier and speaker for paging and night ringing, customer-
supplied Music-on-Hold (MOH) source, separate background music source, reserve power
batteries, and emergency standard telephone for system power failure occurrences
1).
A relay contact is also provided to control one of the following peripherals: MOH source,
night bell, or page amplifier mute control.
