8 Channel PCI Recording Card

8 Channel Ananlog PCI Recording Card

With the open access framework, the SHT series is a powerful and versatile analog telephony interface platform with on-board DSP resources to process fax, conferencing and voice-processing. It is designed to provide developers of highly reliable telecommunications systems with an optimized, cost-effective solution that saves cPCI/PCI/USB slots over traditional designs by combining 2~16 analog Loopstart/Subscriberloop connections with DSP-based enhancements such as fax, conference and voice processing capabilities.

Rooted in all-in-one architecture, hardware design of SHT series adopts modular structure to deliver custom products and high application flexibility for developers and integrators. SHT series boards can be installed with specific modules for station, trunk and recording functions and have high analog interface capability to fit to diverse applications needs. The "USB Box" in the SHT Series is handy for setting up 2~4 port systems for application developers and household users.

The SHT series is also supported by in-house unified API that is operating systemindependent, which makes it highly versatile. With a single, protocol-independent API, programmers can easily and quickly develop applications that run on a variety of telecommunication networks simply by executing protocols on the SHT DSP resources. The in-house unified API unifies application development across all CTI and call recording products.

ON-BOARD FUNCTIONAL MODULES AVAILABLE
offers seven types of modules for SHT series board, including MT, MU, MTU, MR, MR+, MTR+ and MTR. A single module interfaces to an on-board socket and corresponds to two channels. For instance, SHT-16B-CT/PCI is designed with 8 on-board sockets (corresponding to 16 ports), so customers can freely configure 8 modules on the board from the following module types:
MT (Trunk module)
MT is the module that connects to the telephone network (analog loop start lines). It can carry out a series of work such as tone detection, playback/record, caller-ID/called-ID retrieval, polarity reversal detection and DTMF acquisition. Moreover, MT can check the status of telephone wires for its line voltage detection ability. With MT on the board, inbound and outbound calling, teleconferencing, voicemail, IVR and the like solutions can be implemented.
MU (Station module)
MU internally interfaces to the analog telephone set to perform a series of work such as ringing signal, caller-ID (DTMF/FSK), playback/record and DTMF detection. MU works well in solutions such as operator service.
MTU (Trunk/station combined module)
An MTU also corresponds to 2 ports, with one channel performing MT module's function and the other MU's. Besides all the functions inherited from MT and MU, this module offers an added advantage, i.e. phone calls will not be interrupted even when power supply is out thanks to the internal physical connection between the MT and MU.
MR (High-impedance record module)
MR is used for recording inbound and outbound calls and can carry out a series of work such as DTMF detection, tone detection, recording voice and signaling data (caller-ID, called-ID), etc. With MR on the board, a perfect recording solution can be implemented.
MR+ (Microphone record module)
MR+ is the module that connects to a microphone for recording voices and signals through the microphone. MR+ enhances and expands the diversity and flexibility in recording solutions.
MTR+ (Trunk/Microphone record combined module)
An MTU module corresponds to 2 ports, with one performing MT's function and the other MR+'s.
MTR (Trunk/record combined module)
An MTR module corresponds to 2 ports, with one performing MT's function and the other MR's
