CPU usage and increased board density per server. They provide the power to interconnect traditional telephony systems with emerging Voice-over IP (VoIP) technologies. Compared with other products in Synway AST series, the TEJ board has high integration. It is integrated with the capability of 64ms echo cancellation, eliminating the need of getting supports from extra modules or devices, bringing an obviously better effect of echo cancellation than other subseries in AST. -
Page 6: Features
Entirely compatible with Asterisk at the hardware/driver level, with all source codes open. RJ48C Jack TEJ-1A/PCI, TEJ-2A/PCI and TEJ-4A/PCI boards respectively have 1, 2 and 4 RJ48C jacks which can either connect directly with digital trunks or convert to BNC connectors via a proper adapter, making connection easy and malfunctions rare. -
Page 7: Operation Principle
Synway Information Engineering Co., Ltd The self-adaptive echo cancellation feature gives the board the capability of 64ms echo cancellation so as to effectively eliminate echoes under various conditions, canceling out the effect of voice playback on DTMF and busy tones detection, avoiding self-excited oscillation and howling, and minimizing the possibility of registering wrong DTMF and busy tones in a conference call, designed especially for VoIP application environments. -
