2 ~ 4 Analog Ports
2 - 4 analog Loopstart/Subscriber interfaces with call
control and switching in USB slot for combined
trunk/station/recording applications in single box.
Bus Standards
Compliant with USB2.0 bus standard, support hot swap, perfect
for high-portability small-scale systems, and no power supply
needed.
Physical Interfaces
USB Band Box can be connected to phone line through RJ11
connector without need for external wiring box, which
facilitates connection and improve reliability.
On Demand Voltage Detection and Ring Detection
Voltage values and Ring states are reported with standard
SHCTI API events to simplify application development.
Programmable Voltage Thresholds
Easily control voltage detection event by configuring box to
the local analog environment.
Detect Polarity Reversal
Adapt to environments where Tip and Ring are reversed.
Conference Resource
Independent conference resource in each port, support
conference monitoring and BGM; filter DTMF to eliminate DTMF
signal in conference; can configure as interactive
teleconferencing without limit on the number of conferees and
conferences of multi-parties.
All-in-One Architecture
Universal port capability supports Conference and Voice
processing to ensure compatibility and high performance for
leveraging developer time and application investment.
In-House Unified API
Protocol-independent API minimizes system development and
deployment efforts and feature-rich software development kit
support for Windows® and Linux®.
Built-in Voice Processing Resource
Support A-law, µ-law, IMA ADPCM and GSM 6.10 format;
record/playback of Windows WAV file; Programmable tone
generation/ reception/ detection for DTMF; FSK receiver/
transmitter; Adaptive Echo cancellation and Barge-in
functionality.
Full DSP Resources
Implement call control, switching, and enhancements such as
voice play/record, DTMF/MF, call progress functions, echo
cancellation and conferencing. DSP resources are efficiently
managed to minimize host overhead and maximize host processing
time for applications.
On-Box Audio Jack and Microphone Connector
Real-time monitor all channels or playback audio files by
on-board audio jack resources; take microphone recording when
"MIC" connector connects to a Microphone.
In-house Unified API (SHCTI)
A single protocol-independent API minimizes the processing
overhead on system CPU by executing protocols only on The Band
Box itself, freeing your computer's resources for other things.
FSK and DTMF Detection
Handle Call Connection with SPECdial algorithm for dialing
handing and recognizing caller ID in FSK and DTMF modes.
Real Time Monitoring
Real time monitoring by audio Jack for any of channels in
teleconferencing without need of any additional channel.
Safety Protection of User Software
With special built-in identification circuit for each user to
provide a unique authorized number for safety protection of user
software.
Application Environment
Easily customized and compatible with our in-house unified
API, USB Band Box can be configured for multi-channel systems.
In any analog environment, USB Band Box can work well between
Office and PBX, office and phones, PBX and phones and any other
analog audio signals.
Worldwide Analog Support
USB Band Box supports trunk/station on ground start and loop
start analog networks. Features such as programmable voltage
thresholds, voltage detection, ring detection and polarity
reversal are managed through our In-house unified API, so the
products easily adapt or are customized to variations in analog
systems throughout the world.
