Chapter 1 Overview
The DST Series DST-24B/PCI, DST-24B/PCI+, DST-24B/PCI(2.0), DST-24B/PCI+(2.0),
DST-24B/PCIe(2.0) and DST-24B/PCIe+(2.0) are 24-channel digital station tap boards with
PCI/PCIe bus, used especially for recording of digital subscriber lines (extension lines).
1.1 Functions
zHigh-impedance recording of digital phone lines through parallel connection
zA variety of ways to start/stop recording
zSupports simultaneous recording on 24 channels, each with a different format
zSupports independent-recording of incoming, outgoing and mixed-recording
modes
zANI and DNIS support
zSynchronous acquisition of the information displayed on digital phones during
recording
zDetects all modes of keying supported by user phones
zActivity/silence detection
zAutomatic Gain Control (AGC) support in recording operation
zCall progress monitoring
zAutomatically checks board to see if modules are correctly inserted and to
determine the number of modules on the board
zSupports detection and alarming of line faults, including line break and errors in
voltage level, signal-to-noise ratio and synchronization
zSwitches flexibly between voice channels B1 and B2
zBesides, DST-24B/PCI+, DST-24B/PCI+(2.0) and DST-24B/PCIe+(2.0) boards
support MS-GSM, G.729A and MP3 for encoding in hardware
1.2 Features
zPCI 2.2 Bus Support
(DST-24B/PCI & DST-24B/PCI+ & DST-24B/PCI(2.0) & DST-24B/PCI+(2.0))
These four boards include PCI 2.2 bus with burst data transmission rate up to 132
MB/s; the PNP (plug and play) feature they have eliminates the need for jumper
leads; in the universal PCI design, they support 3.3V/5V slot voltage and PCI-X.
zPCIe Bus Support

Synway Information Engineering Co., Ltd
(DST-24B/PCIe(2.0) & DST-24B/PCIe+(2.0))
Developed with the design of PCIe X1, these two boards support PCIe X1, X2, X4,
X8 and X16 slots.
zDMA Transfer Support
The DMA transfer of recording data does not cost any of the host CPU resources,
which helps extend the capacity of recording lines on a single board to an extreme.
zModularized Design
This board is designed with modularized structure and can be configured in
flexible ways. Besides the 8 on-board recording channels, each board can be fitted
with up to 2 recording modules, and each module can support recording of up to 8
digital phone lines. Now it is widely used in various systems.
zAvailable RJ21 Connector
This board has a 50-pin RJ21 connector which is often used for PBXs, making
connection easy and malfunctions rare. With the help of a 24-port RJ21-to-RJ11
adapter that is supplied with the board, users can use the RJ11 jack for direct
connection.
zFits Modules via Inter-plane Connectors
The use of high-precision, streamlined, inter-plane connectors highlights the
characteristic compact and highly-reliable advantage of Synway’s all-in-one
boards.
z1 to 24 Port Hi-Z Monitoring of Digital Lines
This board connects to monitored phone lines via high-impedance and parallel
connection of 2 or 4-lead lines, with the access points flexibly positioned on
communication lines between a digital PBX and some digital phones. In such way,
it is widely used for recording multiple digital PBX and phone models.
zProgrammable Tone Detector
Detects single or dual tones at any frequency, offering facility for use with a variety
of PBXs and key telephone systems.
zRecording of Source Code Stream
When using the board, any problem found on the monitored line can be located
and settled by remote debugging with the cooperation of users.
zRemote Support for New PBX Models
New PBX models can be supported by remote operation, not requiring on-site
helps.
zHigh-impedance Recording
The recording impedance is over 1KΩAC, ruling out interruption on transmission

of monitored signals.
zInstantly-upgradeable Hardware Circuit
Using instantly-upgradeable hardware circuits, the board can support different
models of PBXs and digital phones simply through software reconfiguration, i.e.
there is no need to replace any hardware components. So far, a dozen of
mainstream PBXs, such as Alcatel, Avaya, NEC, Siemens, Nortel, are supported.
zVoice Processing & Signaling Analysis
A single board is capable of processing voices and handling call-signaling analysis,
and can constitute a recording system by itself without the need for supplementary
boards or external devices.
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. In
addition, the DST-24B/PCI+, DST-24B/PCI+(2.0) and DST-24B/PCIe+(2.0) boards
support hardware-based MP3, MS-GSM and G.729A for encoding.
zSupports WAV File
The recorded voice files can be edited and played by audio tools such as Cooledit.
zAudio Output Interface
Equipped with an analog tone amplifier circuit and an output interface, the first
channel on the board can directly connect to the headset or sound box, allowing
monitoring of a specified channel in real time and voice playback only via a simple
function call.
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.
zAuthorization Code Identification Circuit
The on-board authorization code identification circuit is designed for software
safety. Users can apply to our company for the authorization 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.

1.3 Advantages (vs. A-type Boards)
Compared with the old A-type boards (e.g. SHR-16DA-CT/PCI, SHR-24DA-CT/PCI), the
DST-24B/PCI, DST-24B/PCI+, DST-24B/PCI(2.0), DST-24B/PCI+(2.0), DST-24B/PCIe(2.0)
and DST-24B/PCIe+(2.0) boards (hereinafter referred to as B-type boards) are endowed
with the following advantages:
zEnabled to perform digital adjustment of front-end analog circuits in software, to
optimize the input signals before they come into the processor.
zEnhanced capability to detect line faults.
zUse of FPGA chip, to improve the ability of handling complex signals.
zDMA support, to minimize the CPU cost for data transfer.
zEnabled to record on-line source code streams, to locate problems as soon as
possible with the cooperation of users.
zSupport of new PBX models through remote debugging.
zEnabled to configure a monitored voice channel to B1 or B2 in software, provided
the monitored signal is 2B+D.
zFor boards having greater power (e.g. DST-24B/PCI+, DST-24B/PCI+(2.0) and
DST-24B/PCIe+(2.0)): Support of GSM (by default), G.729A and MP3 (by
modifying driver configuration items) compressions.
PS: A-type boards don’t support GSM and MP3 compressions.

1.5 Functional Modules
zMOD-24DB High-impedance Recording Module
This module embraces 8 ports for recording digital phone lines (See Figure 2-10,
Figure 2-11). A board, allowed to have up to 2 modules, is able to identify the
number of on-board modules. Together with the board’s firmware-loading feature,
this module can be used to perform recording of most digital PBXs and telephones
connected via parallel lines.
