Synway Information Engineering Co., Ltd
Chapter 1 Overview
The Synway TEJ100P, TEJ200P, TEJ100E, TEJ200E, TEJ101P, TEJ201P, TEJ101E and
TEJ201E are digital trunk interface boards which support E1, T1 and J1 environments. They are in
2U size, 120mm in length, compact in structure and high in integration. TEJ100P, TEJ200P,
TEJ101P, TEJ201P include PCI bus while TEJ100E, TEJ200E, TEJ101E and TEJ201E include
PCIe bus, designed especially for various application systems that require high performance.
They all perform echo cancellation by on-board DSPs. The enhanced capability of TEJ101P,
TEJ101E, TEJ201P, TEJ201E in echo cancellation reaches 128ms for time delay estimation,
which ensures high-quality voice talk without extra modules or devices to support echo
cancellation. They are cost-effective. The design of on-board EMC and lightning-proof circuits
further guarantee the security in use.
These boards are completely compatible with Asterisk at the hardware/driver level and support
smooth connection to Asterisk platform. Therefore they have a lot of advanced call features.
Supported Data Modes: Cisco HDLC, HDLC, PPP, Multi-link PPP, Frame Relay.
