applicable to PCI Express X1, X2, X4, X8, X16 slots.
zModule Configurable
8 on-board dual channel modules can be freely arranged in pairs or groups for
various complex, multi-functional applications, such as call center and recording
functions available on a single board.
zRJ45 Connectors Available
A single board has four 8-pin RJ45 jacks, each of which can be converted to four
2-pin RJ11 jack via a four-way hub, making connection easy and malfunctions rare.
zTeleconferencing

SHT-16D-CT/PCIe Hardware Manual (Version 1.01) Page 1

Synway Information Engineering Co., Ltd
simultaneous conferences and participants in each conference, allows monitoring
and recording of the whole conference and each individual speaker.
zOn-board Ringing Current & Battery Feed Power Supply
Each station channel has a circuit to generate ringing current and battery feed for
itself, saving the cost on external power supply and facilitating the use.
zFlexible Power Supply Scheme
Multiple power supply schemes are available to provide the 12V power for the boards
using station channels. One option is to connect the P4 D-type hard disk power plug
of the computer, and another choice is to short the S17 pin header and obtain the
power via the PCIe slot. If the power supply inside the computer is insufficient,
external connection of 12V power adapter can be a substitute (Refer to Figure 2-2).
zOvervoltage Protection and Undervoltage Indication
The board is designed with overvoltage protection and undervoltage indication
features. The D1 indicator light is on when the power supply is normal (about 12V).
When the voltage is lower than 10.8V, it is off, indicating the power supply failure
(Refer to Figure 2-2).
zProgrammable Tone Detector
Detects single or dual tones at any frequency, offering facility for use with a variety of
PBXes and key telephone systems.
zSpecialized Driver Algorithm
Uses SPECDial – a specialized driver algorithm - to perform a complete automatic
dial process through analog lines. Accurately identifies called-party statuses and
precisely distinguishes an answering machine from a fax machine that is responding
at the remote end.
zEcho Cancellation
The self-adaptive echo cancellation feature effectively eliminates echoes under
various conditions, which cancels out the effect of voice playback on DTMF and busy
tones detection, avoids self-excited oscillation and howling, and minimizes the
possibility of registering wrong DTMF and busy tones in a conference call.
The board itself has the capability of 16ms echo cancellation. If it is installed with an
E021 module, the capability of echo cancellation will increase to 128ms.
zOptional Modules
Compared with the B-type or C-type analog voice boards Synway launched
previously, the SHT-16D-CT/PCIe board uses the modularized design more
completely. Installing different kinds of modules on a same motherboard of
SHT-16D-CT/PCIe can achieve various features and functions. At present, the
supported modules are only E021 (with echo cancellation capability) and F021 (with
SHT-16D-CT/PCIe Hardware Manual (Version 1.01) Page 2

Synway Information Engineering Co., Ltd
faxing capability).
zVarious CODECs Support
Offers a large selection of voice CODECs, including hardware-based A-law, μ-law,
IMA-ADPCM, software-based 16-bit linear PCM, MP3 and VOX.
zSupports WAV File
The recorded speech files can be edited and played by audio tools such as Cooledit.
zAudio Output Interface
The analog tone amplifier circuit equipped on the first（default）channel allows the
board to connect directly with the headset or sound box, and enable the voice to be
played to a specified channel by simple function calls.
zTDM Capability
The use of H.100 CT-BUS facilitates smooth connectivity to third-party boards with
H.100 bus for the transfer of acquired voice signals to other devices.
zUnique Hardware Serial Number
Each board has a unique hardware serial number written in the firmware to
distinguish itself from other boards and prevent piracy. The number is available via
an easy function call with applications.
zAuthorized Code Identification Circuit
The on-board authorized code identification circuit is designed for software safety.
Users can apply to our company for the authorized code.
zSynway’s Unified SynCTI Driver Development Platform
Synway owns the intellectual property rights for the unified high-intelligence SynCTI
driver development platform. Each system supports up to 2048 channels. Functions
such as the detection and analysis of rings, tones and Caller IDs, are available via
simple function calls on the driver platform, without having to understand complex
call procedures.

2.3 Installation Procedure
Step 1: Plug the desired modules into the module slots on the board, and fit the
board into the PC chassis.
Step 2: Connect to analog lines or phones.
Each SHT-16D-CT/PCIe board has four 8-pin RJ45 jacks each of which can be connected to
four 2-pin RJ11 jacks via a 4-way hub.
Here below we take the first RJ45 jack for example. The corresponding relations among
on-board channel number, 8 pins of the RJ45 jack and interfaces of the 4-way hub are
shown in Table 2-1.
Jack No. Channel No. Pins of RJ45 Interfaces of 4-way Hub
1 1st and 2nd pins 1st interface
2 3rd and 4th pins 2nd interface
3 5th and 6th pins 3rd interface
First RJ45
Jack
4 7th and 8th pins 4th interface
Table 2-1 Corresponding Relations among Channel Number, RJ45 Pins and Hub Interface
Notes:
① To use the first RJ45 jack to connect lines, you can refer to the above relations and
SHT-16D-CT/PCIe Hardware Manual (Version 1.01) Page 9

Synway Information Engineering Co., Ltd
convert it correctly via a 4-way hub. The other three RJ45 jacks are used in the
same way.
② The 4-way hub used to convert the on-board RJ45 jacks can be purchased from
Synway. If you’d like to construct lines by yourself, we suggest you strictly follow
Figure 2-4.
Step 3: Connect to HD power plug or external 12V power adapter
See Figure 2-12 below for how to connect the HD power plug in the chassis to the
motherboard.
HD Power Plug
Figure 2-12 Insert HD Power Plug to Board
Note:
① For the boards before V101, whatever modules you use, you must ensure the HD
power plug is properly connected. For the boards of V101 and above versions, only
those equipped with FXS channels are required to be connected with power plug.
② As the HD power plug may probably be used in more than one place, we provide a
power port extender (one master to three slaves) with the board to offer more plugs.
Then you can connect with more boards. However, considering the limit on the
on-state current, we suggest a master HD power plug be connected with no more
than 4 boards via the power port extender.
③ For the boards of V101 and above versions, if the P4 D-type hard disk power plug is
not available, the 12V power supply can be obtained via the PCIe slot. In this case,
you should short the S17 pin header using the jumper.
④ If the power supply inside the computer is insufficient, another option is to connect
the external 12V power adapter for the FXS channel. The external power supply
should meet the following requirements:
a) Provides 12V DC output, with the output current greater than 3A.
SHT-16D-CT/PCIe Hardware Manual (Version 1.01) Page 10

Synway Information Engineering Co., Ltd
b) Specification of power plug: DC5525.
c) The 12V DC power adapters can be purchased from Synway. Should you have
any requirements, please contact our sales persons.
Step 4: Fit the trunk-station composite module.
Skip this step if direct connection between trunk and station which keeps call uninterrupted
during power outage is not required by the system.
When the trunk-station composite module is used, the station phone and the phone line
which both share the same module can be directly linked before the board is powered on or
the driver software is initialized to allow emergency telecommunication. Once the board
application program starts to run, the link automatically breaks and the internal and external
lines become independent.
Note: When composite modules are used, the adjacent two channels are by default a station
channel and an analog trunk channel. Users can set whichever channel to be a station
channel or an analog trunk one by modifying the configuration file.
Step 5: Connect the sound box or other proper sound devices.
Skip this step if there is no need to ‘monitor in real time’ or ‘play’.
Regarding how to choose proper sound devices, refer to ‘Input/output Interface’ and ‘Audio
Specifications’ in Appendix A Technical Specifications.
Note: The first module slot on the board must be fitted with a module should you wish to play
sound via the amplifier.
Step 6: Connect H.100 bus interfaces on all boards by bus cable.
Skip this step if there is no need for bus exchange between multiple boards.
Notes:
1) See
Figure 2-13 for correct insertion. Do not twist or insert in the opposite direction.
SHT-16D-CT/PCIe Hardware Manual (Version 1.01) Page 11

Synway Information Engineering Co., Ltd
Figure 2-13 Connection of H.100 Bus
2) There are two clock settings for voice boards: When between-board bus exchange is
not required, each board sets its own clock and may not be connected to the bus cable;
otherwise, each board must be connected to the bus cable to follow the clock of the
cable.
3) The bus cable houses a stiff conducting material. Therefore, when it has been shaped,
do not bend it repeatedly or violently lest it is broken.
Step 7: Boot your computer and install the driver.
Regarding driver installation, refer to SynCTI_InstManual.pdf.
Key Tips:
zAs the system is expected to run for long hours unmannedly, ‘energy-saving’ mode
should be turned off for both the CPU and the HD in CMOS or WINDOWS
operating system. This is to ensure full-speed operation of the computer, or it may
lead to a drop in performance or unexpected errors after running for some time.
zA chassis installed with voice boards must be grounded for safety reasons,
according to standard industry requirements. A simple way is earthing with the third
pin on the plug. No or improper grounding may cause instability in operation as well
as decrease in lightning resistance.
