Chapter 1Overview
These Synway E-type digital trunk boards are earmarked for PBX. They have almost all
functions needed for call/voice processing systems which are connected to them through
E1/T1/J1 trunks. These boards are designed with the enhanced capability in echo
cancellation and the DMA Read and Write function which speeds up the data transfer and
minimizes the cost of CPU, further improving the system performance.
1.1 Functions
zA single board accommodates 1, 2, 4 or 8 E1/T1/J1 trunks
zSupports China SS1, SS7 and ISDN connections in E1/T1 mode
zSupports phone calling and voice processing
zActivity/silence detection
zAutomatic Gain Control (AGC) support in recording operation
zEnhanced echo cancellation
zUp to 64 fax channels optional on a single board
zAllows DTMF transmission and detection during voice recording or playback
zIncludes H.110 bus, facilitating smooth connectivity to third-party boards with
H.110 bus for the transfer of acquired voice signals to other devices
zThe flexible distributed conferencing system sets no limit on the number of
simultaneous conferences and participants in each conference, allows monitoring
and recording of the whole conference and each individual speaker
zEquipped with hot-swap circuits to support board insertion and extraction during
runtime, easy for maintenance and backup
zThe on-board lightning-proof circuit reaches the telecom standard and surely
eliminates the damage caused by lightning
zEquipped with the EMI circuit, effectively preventing the electromagnetic
interference
zEach 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
zThe on-board authorization code identification circuit is designed for software

safety. Users can apply to our company for the authorization code
zCompatible with other series of voice boards from Synway
1.2 Features
zDMA Read and Write
Uses the DMA technology based on PCI bus to read and write data, greatly reducing
the CPU cost.
zE1/T1/J1 Support
Provides an easy selection of the E1, T1 or J1 trunk and its matching impedance via
software reconfiguration, not requiring any change in hardware.
zSignaling Interface
SS1 provides two levels of interfaces respectively for MFC transmission/receipt and
SS1 connection; SS7 provides two levels of interfaces respectively for MTP and
TUP/ISUP, meeting various customer requirements.
zSignaling Processing
Installed with loadable signaling processing modules, each board supports SS1, SS7
and ISDN, eliminating the need for extra signaling boards. The signaling processing
program can be upgraded via a simple software configuration, without having to
change the hardware.
zSignaling Links
Each board supports up to 8 signaling links and the signaling hot-backup feature, i.e.
the signaling can be processed by the standby server whenever something is wrong
with the links being used, which increases the flexibility and reliability in a great
extent. All the timeslots ranging from 1 to 31, not only TS16, can be used for SS7 and
ISDN signalings.
zProgrammable Tone Detector
Detects single or dual tones at any frequency, offering facility for use with a variety of
PBXes and key telephone systems.
zSoftware-based Terminal Matching
A single board supports several kinds of trunks which differ in impedance. They are
100ΩT1, 110ΩJ1 and 120ΩE1 twisted-pair cables and 75ΩE1 coaxial cable. Both
transmit and receive terminals on the board are specified via software configurations,
facilitating easy connections to a variety of digital trunks and optical transceivers.
zSpecialized Driver Algorithm
Synway SSW Series E-type Digital Trunk Boards Hardware Manual (Version 1.1) Page 2
Synway Information Engineering Co., Ltd
The driver uses SPECDial - a specialized driver algorithm - to perform a complete
automatic dial process through digital trunks and to accurately identify the
called-party status.
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
tone detection, avoids self-excited oscillation and howling, and minimizes the
possibility of registering wrong DTMF and busy tones in a conference call. Among
the products introduced in this file, the SHD-30/60E-CT/PCI/EC(SSW),
SHD-120/240E-CT/PCI/EC(SSW), SHD-30/60E-CT/PCI/FAX(SSW),
SHD-120E-CT/PCI/FAX(SSW) boards have an increased capability in echo
cancellation and offer a much better effect in this aspect.
zA Particular Separation Design
As the mainboard and the outlet board are designed independent from each other,
when you pull out the mainboard or reinsert it or replace it with other boards, there is
no need to reconnect lines as long as the outlet board is not changed or removed.
zBarge in
Supports the Barge-in feature.
zVarious CODECs Support
Offers a large selection of voice CODECs, including hardware-based A-Law (G.711),
μ-Law, IMA ADPCM and software-based 16-bit linear PCM, MP3.
zSupports WAV File
The recorded voice files can be edited and played by audio tools such as Cooledit.
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. The
complex call procedures can be analyzed and controlled through simple function
calls on the driver platform, without having to understand details.
