Chapter 1 Overview
The Synway TEJ101E and TEJ201E are digital trunk interface boards which support E1, T1 and
J1 environments. They are in 2U size, half-length, compact in structure and high in integration.
They use high-performance standard PCIe bus, designed especially for various application
systems that require high performance.
The TEJ101E and TEJ201E boards perform echo cancellation by on-board DSPs. The echo
canceller developed by Synway supports up to 128ms for time delay estimation, which ensures
high-quality voice talking without the help of extra modules or devices for 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.
Supported Voice Modes:

The TEJ101E and TEJ201E boards connect Asterisk Server with PSTN, Channel Bank or PBX via
T1, E1 or J1 interface to build a specialized telephony network environment. Figure 1-1 and Figure
1-2 below are typical application models with these boards.

1.1 Features
zPCIe Bus Support
Includes PCIe bus; supports PCI Express X1, X4, X8, X16 slots and PNP (plug and play)
feature.
zDMA Read and Write
The use of DMA technique for data reading and writing helps minimize the cost of the host
CPU.
zCompatible with Asterisk
Entirely compatible with Asterisk at the hardware/driver level, with all source codes open.
zRJ48C Jack
The TEJ101E and TEJ201E boards respectively have 1 and 2 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.
zEcho Cancellation
The echo canceller developed by Synway uses on-board DSPs to work. It supports up to

128ms for time delay estimation per channel, really cost-effective. It not only cancels out
the effect of voice playback on DTMF and busy tones detection, but also avoids self-excited
oscillation and howling, and minimizes the possibility of registering wrong DTMF and busy
tones in a conference call, designed especially for VoIP application environments.
zVoice CODEC Support
Supports A-law, μ-law codecs.
zClock Sync Support
The TEJ101E and TEJ201E boards support input and output of CT clock, allowing clock
synchronization with multiple boards.
