Enhanced Key Telephone
The Enhanced Key Telephone is fully equipped for hands-free, speakerphone operation. 
This key telephone is expanded to 28 buttons. Eight fixed function buttons remain 
consistent with those of the Basic Key Telephone. 
Twenty buttons are user-programmable feature buttons equipped and dual color LED 
with pre-assigned default settings for quick power up operation. These buttons are 
arranged in five rows and four columns. Beginning at the top left button they are 
assigned the following default values; Station 10 - 21, CO line 1-6, HF/Tone and Message 
Waiting. The Enhanced Key Telephone also is equipped with a 12-key Dial Pad for dialing 
intercom numbers, system feature codes and telephone network numbers on CO lines.
Figure 2-7: Enhanced Key Telephone
Each telephone is equipped with an Additional Device Port (ADP) located on the 
underside of the phone for user-friendly connection of analog devices (answering 
machines, faxes, modems, cordless telephones, etc.). An analog adapter is required for 
this port to be equipped for use as an extension of the system.

Executive Key Telephone
The Executive Key Telephone model has a 2 x 16, 32-character Super Twist LCD display, 
with three interactive Soft Buttons to enhance system features operation.
The Super Twist LCD eliminates the need for contrast adjustment and enhances angled 
viewing position clarity of displayed data. A visual reference to call progress and call 
duration, as well as time and date information, is displayed. The display also enables the 
Executive Key Telephone user to send and receive visual advisory and call-back 
messages.
The Executive model telephone is fully equipped for hands-free, speakerphone 
operation, and enables hands-free outgoing and incoming calls. The same 20 
Programmable Feature Buttons are available on the Executive model, as on the 
Enhanced model. Eight fixed function buttons remain consistent with those of the Basic 
and Enhanced Key Telephone.

Each telephone is equipped with anADP located on the underside of the phone for user-
friendly connection of analog devices (answering machines, faxes, modems, cordless 
phones, etc.). An analog adapter is required for this port to be equipped for use as an 
extension of the system. 
						

							2-10DHS General Description
Direct Station Selector (DSS) Console 
Previously only available on the DHS-E, the Direct Station Selector (DSS) Console is now 
also available on the DHS. One DSS Console may be assigned to a station. Each DSS 
Console uses one Digital Station Port. Up to 12 DSS Consoles can be installed on a 
system.
The DSS Console buttons are programmed by the Station User using the FEAT + # + 5 
command, then pressing the button on the DSS to be programmed. All system feature 
codes may be stored on the Programmable Feature Buttons for one-button operation. 
Certain programmed feature buttons will light when activated (DND, Call Forward, DSS/
BLF, etc.), while others such as Call Pick-Up, BGM and Last Number Redial do not.
Features are separated into three distinct categories for programming on a button: CO 
line, station, or feature.

2-Port Analog Adapter
A 2-Port Analog Adapter is optionally available which will support most auxiliary 
equipment within a business environment such as fax machines, answering devices and 
Single Line Telephones (SLT). Each adapter requires an unused digital station port and 
will yield two analog device interfaces.
The 2-Port Analog Adapter is a wall mount apparatus that is powered from the KSU. The 
adapter receives both voice channels and data control from the KSU, over one pair of 
wires. The 2-Port Analog Adapter generates -30V DC and 20-25Hz, 50V square wave 
ringing for operation of SLTs, fax machines, answering devices, and most modems. All 
terminations are by RJ-11 connection.
The analog Adapter utilizes the B1 channel for voice tip/ring connection to one analog 
station, and the B2 channel for the other. D channel provides port control to and from the 
KSU. The adapter provides two DTMF receivers (one for each analog port). Third party 
analog devices connected to the 2-Port Analog Adapter must generate DTMF signaling 
(Pulse/rotary dial telephones/equipment are not supported). The 2-Port Analog Adapter 
provides adequate housing space for one 2-Port Analog Expansion.

Loop disconnect and message waiting lamps are not supported by the analog adapter. 
						

							2-12DHS General Description
Two-Port Analog Expander
A 2-Port Analog Expander module is optionally available and is designed to be installed 
inside the 2-Port Analog Adapter housing. The 2-Port Analog Expander provides the 
same interface capabilities of the 2-Port Analog Adapter and is in fact comprised of the 
same circuit board used inside the 2-Port Analog Adapter. Loop disconnect and message 
waiting lamps are not supported by the analog adapter.
Figure 2-11: 2-Port Analog Expander
The 2-Port Analog Expander requires its own, dedicated digital DHS port for operation.
