GENERAL DE§CFWTION I , 
OVERVIEW 
The general description section provides detailed information of the operation of the 
MT-16H Electronic Key Telephone System. The CPU, network interface and 
’ 
system components are described in order to provide a working knowledge of the 
equipment and its operation. 
GENERAL DESCRIPTION OF THE KSU 
The system architecture of the MT-16H is designed with “state of the art” 
components and high quality design criteria. The system is organized...

The user programmed data is backed up by a 3.7 volt NICAD battery that isunder 
constant trickle charged by the KSU power supply. The NICAD is also used to 
provide backup voltage for the real time clock. The NICAD battery will protect the 
speed dial numbers and customer database until the power.outage exceeds 
approximately 40 hours. 
When the AC power is turned ON, the NICAD recharges. 
Memory 
power backup circuitry is monitored by voltage detecting circuitry 
controlled by the CPU and, in turn,...

POWER SUPPLY 
The power supply section consists of components which change 1 lo/220 AC 
voltage into the DC voltage which the integrated circuits use. Working in 
conjunctionwith this circuitry, the 
MT-16H employs an on-line monitoring circuit 
which detects under-voltage and over-voltage. 
In the event the system loses AC voltage and the system battery backup has been 
installed, the system detects when the batteries have discharged to such a rate that 
the KSU is no longer usable. Instead of allowing...

DOORPHONE 
The MT-16H main PCB contains circuitry for one door-phone. Calling to and from 
the KSU is standard. A door lock relay contact is also provided. The user, after 
answering the call, may press-the door key (or dial 3) which, in turn, activates the 
relay. Database Programming.activates the hardware. 
EXPANSION CARDS 
The MT-16H KSU supports the following three expansion cards: 
MT-STU/A 
Provides an additional capacity of 2 CO lines and 4 keysets. Programming activates 
the additional CO lines...

, 
SINGLE LINE TELEPHONES 
Any 
industrial standard single line telephone may be installed on the MT-16H. The 
total ringer equivalency should not exceed 5.OB per single line port or damage to the 
system might result. 
ELECTRONIC TELEPHONE SETS 
The MT-16T telephones support 8 CO lines and 16 stations. It has a built-in 
speakerphone and an optional LCD unit which may be installed at a later date. Any 
phone location may be used to program the system database as long as the correct 
security code is...
