The ht-322 is designed as a compact, high performance, and low cost fxo gateway. The fxo detection is optimized to avoid the hold up of the pstn line when the other party is disconnected. This has been one of the key issues in the design of fxo gateway. The incoming pstn caller id is also transmitted to the voip user for more user friendly operation. The ht-322 is a full featured fxo gateway and is designed for easy installation and configuration. It is an ideal solution for voip to pstn termination in both sme and soho environment.

1310 nm optical transmitter 1). Product profile The unit applies the imported high linear dfb laser with low noise, big transmission capability and small nonlinear distortion. It is completed with reliable apc (automatic power control) circuit for light power output and atc (automatic temperature control) for thermo-electric cooler, mgc (manual gain control) and agc (automatic gain control) circuit for distortior input radio-frequency drive current. Agc applies the automatic digital processing technology for radio frequency power, by which the driving level power can be automatically processed according to the level of input radio frequency and the channel quantity, and the output level of the optical receiver can keep constant to maintain the cso, ctb and c/n indexes at the optimum state all the time, thus to ensure the stable operation of the chain indexes and the laser all through its service life. A gaas element is adopted as the preamplifier, which not only lowers the input level and adds a radio frequency predistortion circuit, but also enhances the cso, ctb and c/n indexes. The built-in microprocessor software provides multiple functions including real-time monitoring for the transmitter operating state, digital display, aural-visual alarm and network management. Once an operational parameter of the laser runs out of the preconfigured allowable range, the power supply to the laser will be automatically switched off, and the red indicator will flash for warning. The embedded blue screen lcd on the front panel indicates various tasks of the unit, parameters and fault messages in chinese distinctly. The optical transmitter provides standards rs-232 and rs-485 interfaces for network management and remote monitoring. The optical transmitter applies standard 19fª 1u rack, which is provided with high efficient switching power supply for transmitting catv, telephone, and digital or compressed digital data. OEM/ODM serveice available.
