DHS-E Description
System Technolog y
Incorporating state-of-the-art digital technology for voice switching and call processing, 
the DHS-E  utilizes Pulse Code Modulation and Time Division Multiplexing (PCM/TDM). 
The DHS-E  family is engineered to allow migration of digital telephones and accessories 
throughout the entire product line (refer to Digital Key Telephones, in Chapter 2, DHS 
Description and Installation). ISDN-like, 2B+D technology complements the system 
architecture...

3-2DHS-E Description
DHS-E  is expandable to meet a variety of applications. Regardless of the configuration, 
the system has sufficient resources to allow completely non-blocked access to all facilities 
(intercom and CO lines).
An external music source may be connected to each BGM/MOH Jacks via a 1/8 in. phono 
plug for BGM/MOH listening. All system features are supported by the equipment 
provided in the DHS-E  KSU. The Main Processor Board provides two Dual Tone Multi-
Frequency (DTMF) receivers and...

System Administration
The systems 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-E Systems. This Software allows 
the user to program OFF/LINE and...

3-4DHS-E Description
Power Supply
The power supply circuitry of the DHS-E incorporates a linear design transformer with a 
choice of input voltage taps. The transformer primary windings are shipped wired for 
117V AC applications. Since the power supply is linear in design the output voltage varies 
between 21.6V DC and 32V DC depending on load and stability of the input voltage. The 
output voltage is delivered to the CPU board for distribution and rectified there for logic 
and control voltages.

Figure 3-2: Firmware Caution
Figure 3-3: 3 x 8 Module
Although all existing 3 x 8 boards can be used when upgrading an existing DHS system, 
some pre-qualification must be performed. This pre-qualification will prevent noise 
problems on stations that can result from a firmware incompatibility issue. This issue can 
be corrected by obtaining the correct firmware from Vodavi (refer to 
Figure 3-2: Firmware 
Caution
 for further information).
