Section 1 Basic System Construction

Outside (CO) line board is take on connect with PSTN,
various CO line signal can transmit to each extension
port by tone exchange system that in CO line board to
realize communicating between CO line and Extension.
Allowed maximum install two pieces of CO line board,
and have 8 CO line ports in each CO line card, maximum
have 16 CO lines.
The port order of No.1 CO line board are 01~08 from the
bottom up; the No.2 CO line board are 09~16 from the
bottom up.
The line will priority enter the idle lower CO line port
when internal extension make the external call.
To reduce the CO lines are occupied by the outgoing
calls, we suggest to connect the high-frequency used
CO lines that for external call incoming to the higher
CO line port
Arrester is a device to be installed on outside (CO) line
to prevent a damaging from thunder. We recommend
to install arrester. In addition, grounding (connection to
earth ground) is very important to protect the system.
(Thunder damaging is void warranty)
Extension board is connecting with internal telephone,
the system can build internal communication or external
call by tone exchange system.
Maximum allowed connect with sixteen extension cards,
have 8 extension ports in each board, total have 128
extensions. The port order of each extension board is
increased from the bottom up, The No.1 card are 01~08,
the No.2 board are 09~16 from the bottom up, thus
analogically.
We are recommend to installed the arrester for extension
lines when the extension lines are expose at outdoor.

A lightning protector is a device to be installed on an outside (CO)line to prevent
a dangerous surge from entering the building and damaging the equipment, please
use less 10ohm resistor grounding arrester for CO line.
3.System must be at well grounding condition, otherwise system may operates
un-properly.
Avoid install telephone cable at outdoor, do not wire telephone cable in parallel
with power source, computer, telex, etc. Otherwise, the system operation may be
interfered by the electromagnetism from such equipment.
Install at least 50cm away from flammability or volatile, avoid install on dusty
places, or places where water or oil may come into contact with system.
Unplug the system when change card, draw or insert card vertically.
Adopt power switching, input voltage is 80V~260V, power switching only
control DC power, don't control AC power.
8.The system can be equipped with an external music source to replace internal
built-in music, input signal voltage range is 0.5V~2V. Voice Recorder port is
exclusive for connect with monitor voice recorder(model LH-2000).
9.System serial communication port is for connect with PC COM port, allows
realize multi-functions application and PC charge function when work with our
CTI (computer and telephone integrated ) software.
10.Please read manual carefully before connecting and programming, avoid error
program cause system doesn't operates properly, please reset power supply
when a failure occurs, or contact with your dealer. This unit may only be
installed and served by qualified service personnel.

Section 2 System Programming
2.1.1 This system has a default factory setting. If any of the programming needs to be
changed, the user can change the setting by system programming.
2.1.2
2.1.3 The user should input the password to enter the system programming.
2.1.4
2.1.5
2.1.6
2.1.7
2.1.8 In this manual, we have marked when the functions are different for different
model AK,HK,DK,VK.
All programming must be operated on extension 1 (default is 8001) or by computer
when use our CTI software. When extension is at direct outgoing mode, please input
'' * '' to enter internal dial mode first, then go ahead.
Input '' * '' to start program and end with '' #'', allows input '' * '' to restart program
in the event of failure program occurs.
A long BEEP tone indicates correct programming, if instead of three serial BEEP
tone indicates error programming.
If without special remark, here in manual extension number ''ABCD'' indicates
extension current number, not default extension number.
Any extension is capable connect with our key telephone, plug and play when change
single line telephone to key telephone; however, when change key telephone to single
line telephone, you are required to input format ###0 on key telephone first,
otherwise, system may doesn't operates properly.

2. The port number 1 to 8 of No.2 CO line card are correspond to actual CO
line 9 to 16.
3. The line will priority enter the idle lower CO line port when internal
extension make external call. Example,CO line 1,2,3,4,5 have been
connected, the extensionA will access CO line 1, meanwhile, extension B
will access CO line 2.
To reduce the CO lines are occupied by the outgoing calls , we suggest to
connect the high-frequency used CO lines that for external call incoming
to the higher CO line port
4. The CO line can be connected do not accord to the order, for example, we
can connect CO line 1,2,5,6,7,8, leave the port 3 and 4 are vacant.
