I. System Overview
i. System Operation
Sigma V KT848 system is a stored program controlled electronic key telephone
system ready to use as soon as it is turned on. A powerful microprocessor digitally
controls all speech paths and system functions. The operating program with default
memory is stored in non-volatile ROM. Customer data is stored in RAM and protected
by a Ni-Cd battery for up to at least one month’s continuous loss of system power.
When AC power is restored, the Ni-Cd battery will be recharged.
ii. System Configuration
Sigma V KT848 system has a basic capacity of 4 CO line ports and 16 extension ports,
which can be extended to 8 CO and 48 extensions in maximum by adding optional
expansion boards. This system can be used for both feature phones and single line
phones. Extension ports 1 to 4 are assigned for either feature phone or single line
phones. The extension ports can be connected with single line phones as well as
faxes, recording machines and cordless phones etc.
Sigma V KT848 system has three kinds of expansion boards:
y4 ports CO line expansion board (1 pc. expandable at max.)
y8 ports Extension expansion board (4 pcs. expandable at max.)
y7 ports Caller ID board (1 pc. at maximum)
Combining the strapping options of basic KSU with all the combinations of expansion
boards, Sigma V KT848 system is extremely flexible. The maximum numbers of each
circuit type available in a fully configured Sigma V KT848 system are listed below.
Circuit Type Maximum Number Available
Feature Phone 4
Single Line Phone 48 (if no any feature phone)
CO Line (Loop Start) 8
Remarks: Two features will reduce the system capacity:
1. Caller ID occupy 1 CO port
2. DISA Trunk-to-Trunk occupy 1 Ext port

III. Installation
System installation is shown as below:
i. Main unit installation
Remark:
- Make sure that have enough space to open the cover of Main Unit, switch on/off
power and make a connection with parallel interface
- Measure the length between two holes for wall mount, and then drill and put it on the
wall
- Put the ground terminal connect to earth through ground wire

Notes
1. The Sigma V KT848 system should be installed in a place away from vibration and
moisture, which is clean, dry and ventilated. Do not either put sundries on the KTU
or block its vent hole.
2. While you are wiring the extensions, it is a good idea to mask the wires off the power
line and other high frequency links or keep them at least 1m away.
3. When the crystal heads (RJ11) of all the extensions are compressed, please check
whether the heads are properly connected to the telephone lines to make sure all
the contacts work properly and whether the crystal heads and their bases are loose
or not.
4. The feature phone is provided with one connecting line of four cores; if you want to
make it longer, please be careful with the order of the four cores, where the two in
the middle are for signaling and the two in both sides for data transmission. If you
need to add more crystal heads for joints, please refer to the diagram (if the
operating distance of the feature phone connecting line is less than 100m, while
compressing the crystal heads for joints, you must disconnect the connecting line
from the host).
5. Be sure that the power plug of the KTU is properly plugged into the power socket.
Do not share the power socket with other equipment such as air conditioner and
electric motor etc.
6. When the system is fixed, switch on the power, and the working voltage is 220VAC
(please refer part II in details).
7. See to the power, backup power inclusive, is switched off when any component
except for the plugging and unplugging of the crystal heads of the inside and
outside lines inside the system is to be altered. It is suggested no lines be
connected to the extension ports, which are in no use.
8. The KTU must be connected to ground for fear of thunder stroke. Be sure that the
ground wire is in proper contact with the ground so as to make the most of the
lightening proof function of the system.
