DHS General Description 2-3
System Administration
The system default customer data base can be entered and changed, under password
control, from any Executive Key Telephone. All Customer information is protected by an
internal rechargeable NiCad or NiMh battery. Programmable password protection is
allowed for each station, system administrator and external (DISA) callers. An optional PC
Programming Software is available to program the
DHS system. This Software allows the
user to program offline and then upload directly to the system. The DHS requires the
Option Module to use the PC Programming Software.
Key Service Unit (KSU)
The DHS Key Service Unit (KSU) is a modular flat-pack design. It is a self-contained cabinet
with internal power supply, common control circuits (CPU board) and 3 x 8 module. The
power supply AC transformer is hard-wire selected for either 117V AC (
+
10%). The KSU is
designed for wall mount and shipped with a wall mounting template. The compact KSU
weighs less than 20 pounds and is UL compliant.
Standard inserts installed over various KSU openings may be removed or repositioned to
accommodate exterior connection requirements; three such panels are present. One may
be removed to route a serial cable through the KSU outer housing for connection of
SMDR equipment. Another may be removed to route a serial cable through the KSU outer
housing for connection of a modem or PC (via a straight-through cable). This serial port is
used for Caller ID, PC programming and maintenance. Both serial ports are provided
when the Option Module is installed.
One KSU opening panel may be removed or repositioned to accommodate cable entry
requirements through the outer housing for connection to the MDF.
